Chapter 1. IBM PC Server Technologies IBM PC Servers use a variety of technologies. This chapter introduces many of these technologies and gives examples of system implementations where they are used. 1.1 Processors The microprocessor is the central processing unit (CPU) of the server. It is the place where most of the control and computing functions occur. All operating system and application program instructions are executed here.
performance. (Please see 1.3, “Memory” on page 3 for a discussion of memory speeds and system performance.) The point is that you cannot compare system performance by simply looking at the speed at which the processor is running. A 90 MHz machine with a set of matched components can out perform a 100 MHz machine which is running with slow memory. IBM PC Servers are always optimized to incorporate these factors and they always deliver a balanced design. 1.1.
1.2 Multiprocessing Multiprocessing uses two or more processors in a system to increase throughput. Multiprocessing yields high performance for CPU intensive applications such as database and client/server applications. There are two types of multiprocessing: • • Asymmetric Multiprocessing Symmetric Multiprocessing Asymmetric Multiprocessing: In asymmetric multiprocessing the program tasks (or threads) are strictly divided by type between processors and each processor has its own memory address space.
The key is to achieve a balanced design where the speed of the processor is matched to that of the external components. IBM engineers achieve a balanced design by using several techniques to reduce the effective access time of main system memory: • Cache • Interleaving • Dual path buses • SynchroStream technology 1.3.1 Caches Research has shown that when a system uses data, it will be likely to use it again.
• Write-Back Cache Write operations are also performed on the cache. Transfer to standard memory is done if: − − Memory is needed in the cache for another operation Modified data in the cache is needed for another application The third level of cache or L3 cache is sometimes referred to as a victim cache. This cache is a highly customized cache used to store recently evicted L2 cache entries. It is a smaller cache usually less than 256 bytes.
Dedicated Cache: This SMP design supports a dedicated L2 cache for each processor. This allows more cache hits than a shared L2 cache. Adding a second processor using a dedicated L2 cache can improve performance as much as 80%. With current technology, adding even more processors can further increase performance in an almost linear fashion up to the point where the addition of more processors does not increase performance and can actually decrease performance due to excessive overhead.
In interleaved systems, memory is currently organized in either two or four banks. Figure 3 on page 7 shows a two-way interleaved memory implementation. Figure 3. Two-Way Interleaved M e m o r y Banks Memory accesses are overlapped so that as the controller is reading/writing from bank 1, the address of the next word is presented to bank 2. This gives bank 2 a head start on the required access time. Similarly, when bank 2 is being read, bank 1 is fetching/storing the next word.

1.4 Memory Error Detection and Correction IBM PC servers implement four different memory systems: • Standard (parity) memory • Error Correcting Code-Parity • Error Correcting Code (ECC) memory • ECC Memory on SIMMs (EOS) Memory 1.4.1 Standard (Parity) Memory Parity memory is standard IBM memory with 32 bits of data space and 4 bits of parity information (one check bit/byte of data).
Figure 5. ECC M e m o r y Operation As the data is read from memory, the ECC circuit again performs a scan and compares the resulting pattern to the pattern which was stored in the check bits. If a single-bit error has occurred (the most common form of error), the scan will always detect it, automatically correct it and record its occurrence. In this case, system operation will not be affected. The scan will also detect all double-bit errors, though they are much less common.
Figure 6 on page 11 shows the implementation of ECC-P. When ECC-P is enabled via the reference diskette, the controller reads/writes two 32-bit words and 8 bits of check information to standard parity memory. Since 8 check bits are available on a 64-bit word, the system is able to correct single-bit errors and detect double-bit errors just like ECC memory.
1.4.5 Performance Impact As previously discussed, systems which employ ECC memory have slightly longer memory access times depending on where the checking is done. It should be stressed that this affects only the access time of external system memory, not L1 or L2 caches. Table 1 shows the performance impacts as a percentage of system memory access times of the different ECC memory solutions. Again, these numbers represent only the impact to accessing external memory.
1.5.1 ISA Bus The Industry Standard Architecture (ISA) is not really an architecture at all but a defacto standard based on the original IBM PC/AT bus design. The main characteristics of the ISA bus include a 16-bit data bus and a 24-bit address bus. The bus speed is limited to 8 MHz and it did not allow for DMA and bus masters in its original form. It does not support automatically configuring adapters and resolving resource conflicts among adapters nor does it allow for sharing of interrupts.
Figure 7. Micro Channel - Basic Data Transfer (20 MBps) However, in many cases, blocks transferred to and from memory are stored in sequential addresses, so repeatedly sending the address for each 4 bytes is unnecessary. With data streaming transfers, the initial address is sent, and then the blocks of data are sent; it is then assumed that the data requests are sequential. Figure 8 shows 40 MBps data streaming in operation. Figure 8.
The Micro Channel supports another mode of data streaming whereby the address bus can also be used to transfer data. This is depicted in Figure 9 on page 15. Figure 9. Micro Channel - Data Streaming Transfer (80 MBps) As can be seen from this figure, in this mode, after the initial address is presented during the first bus cycle, the address bus is then multiplexed to carry an additional 32 bits of data. This results in an effective data transfer rate of 80 MBps.
is available with previous bus architectures. In order to optimize performance, the PCI architecture strictly limits the number of loads (hence the number of adapters) on the bus. It therefore needs an I/O expansion bus to handle the more routine I/O devices. The bus has 32 or 64 bits of address and data, is processor independent and is capable of speeds over 50 MHz. 8-bit and 16-bit devices are not supported.
4. Small Computer System Interface (SCSI) - The SCSI interface is a high speed parallel interface that transfers eight bits at a time rather than one bit at a time for the ST506 and ESDI serial interfaces. Thus data transfer rates for SCSI are measured in mega bytes versus mega bits and are considerably faster than those of the serial interfaces. SCSI is also a bus level interface which makes it very flexible.
It defines an 8-bit interface with a data transfer rate of 5 MBps. SCSI-II is the second SCSI standard and is defined in ANSI standard X3T9.2/375R REV10K. It defines extensions to SCSI-I which allow for 16 and 32-bit devices, a 10 MBps transfer rate, and other enhancements discussed below. • Common Command Set The SCSI standard defines a set of commands which must be interpreted by all devices that attach to a SCSI bus. This is called the common command set.
SCSI bus bandwidth. If the controller held onto the bus while waiting for the device to seek, then the other devices would be locked out. This is also sometimes referred to as overlapped operations or multi-threaded I/O on the SCSI bus. This feature is very important in multitasking environments. • Synchronous versus Asynchronous An asynchronous device must acknowledge each byte as it comes from the controller. Synchronous devices may transfer data in bursts and the acknowledgments happen after the fact.
standard 8-bit SCSI devices. Up to seven SCSI physical devices may be attached to this adapter. This adapter has a dedicated 80C186 local processor on board, which allows it to implement advanced features such as TCQ. The dual bus design of the adapter prevents access to internal DASD from the external port. It also allows the maximum cable length to be calculated individually for each bus. This allows for additional capability externally.
In addition to the features supported with the IBM SCSI-2 F/W PCI Adapter, the IBM SCSI-2 F/W RAID adapter provides a RAID controller. Please reference 1.6.5, “RAID Technology” on page 22 for a discussion on RAID. 1.6.3.1 Summary The following tables summarize the features of the IBM SCSI adapters. Table 3.
to the desired cylinder of the disk. The latency is the amount of time it takes for the disk to rotate to the proper sector on that cylinder. It should be noted that two disks of the same physical size, for example 3.5-inch disks, will differ in their access times with the larger capacity disk having a better access time. This is due to the fact that the distance between cylinders is shorter on the larger disk and, therefore, seek time is reduced.
Disks are often among the least reliable components of the computer systems, yet the failure of a disk can result in the unrecoverable loss of vital business data, or at the very least a need to restore from tape with consequent delays. • Cost It is cheaper to provide a given storage capacity and a given performance level with several small disks connected together than with a single disk. There is nothing unusual about connecting several disks to a computer to increase the amount of storage.
1.6.6.1 RAID-0 - Block Interleave Data Striping without Parity Striping of data across multiple disk drives without parity protection is a disk data organization technique sometimes employed to maximize DASD subsystem performance (for example, Novell NetWare′ s data scatter option). An additional benefit of this data organization is drive spanning . With data striped across multiple drives in an array, the logical drive size is the sum of the individual drive capacities.

RAID-1 (Disk Mirroring) Disk mirroring involves duplicating the data from one disk onto a second disk using a single controller. Disk duplexing is the same as mirroring in all respects, except that the disks are attached to separate controllers.

1.6.6.4 RAID-2 - Bit Interleave Data Striping with Hamming Code This type of array design is another form of data striping: it spreads the data across the disks one bit or one byte at a time in parallel. This is called bit (or byte) interleaving. Thus, if there were five disks in the array, a sector on the first drive will contain bits 0 and 5, and so on of the data block; the same sector of the second drive will contain bits 1 and 6, and so on as shown in Figure 16.
1.6.6.5 RAID-3 - Bit Interleave Data Striping with Parity Disk The use of additional disks to redundantly encode customer′s data and guard against loss is referred to as check sum, disk parity or error correction code (ECC). The principle is the same as memory parity, where the data is guarded against the loss of a single bit. Figure 17 shows an example of RAID-3.

1.6.7 Recommendations • Use IDE on smaller systems IDE actually outperforms SCSI on systems where only one or two devices are attached. Several models of the IBM PC Server 300 and 320 lines implement IDE as an integrated controller on the planar board. This is more than adequate if no more than a couple of hard disks will be used.
system memory because they occur across an I/O expansion bus. This means that when shared RAM adapters are involved, the CPU spends a significant amount of time doing the primitive task of moving data from point A to point B. On lightly loaded servers providing traditional productivity applications such as word-processing, spreadsheets, and print sharing, this is not really a problem.
sometimes moves quickly to the CPU when servers are upgraded to incorporate LANStreamer technology. Of course, other components can emerge as the bottleneck as throughput increases. The wire (network bandwidth) itself can become a bottleneck if throughput requirements overwhelm the ability of the network technology being used. For example, if an application requires 3 MBps of throughput, then a token-ring at 16 Mbps will not perform the task. In this case a different network technology must be employed.
• • • Attaching more than four Ethernet 10Base-2 segments to the server Providing switching between 10Base-T and 10Base-2 segments Conserving server slots An add-on to NetFinity provides an advanced Ethernet subsystem management tool. Parameters such as packets/second or total throughput can be monitored for each port, for traffic within an adapter, or for traffic between adapters.
1.8.1 Tamper-Evident Cover Systems equipped with a tamper-evident cover have a key lock for their covers and internal I/O devices. In the locked position, it mechanically prevents the covers from being removed. The key has been changed to a type that can be duplicated only by the manufacturer. If the covers are forced open, an electro-mechanical switch and perimeter sensor detect the intrusion.
there is a power failure; the machine is able to recover with the keyboard lock still in place. 1.8.3.1 Privileged-Access Password Because the power-on and keyboard passwords can be defeated by deactivating the battery inside the system, another level of password protection is provided. This security feature is called the privileged-access password. It provides a much higher level of security.
1.8.5 Selectable Drive Startup Selectable drive startup allows the system owner or administrator to select the IPL source and sequence. This allows the system owner to control the IPL source, but prevents the user from modifying the source and sequence. For example, the diskette drive can be excluded as an IPL source. This feature helps to ensure that the system owner′s specified operating system is loaded.
manage those products. As DMI technology evolves, installation and management in desktops and servers will become easier. It should be noted that the DMI specs say nothing about the transport protocol that is used between the manageable products and the management applications. Both of these elements of a DMI compliant system can be implemented using any native transport protocol available in the system.
The simplest MIF file contains only the component ID group, but MIFs can become as complex as needed for any given product. 1.9.1.3 Management Interface (MI) The management interface (MI) shields managements applications from the different mechanism used to obtain management information for products within a desktop system. The MI allows a management application to query for a list of manageable products, access specific components and get and set individual attributes.
SNMP provides a means of communicating between the network management stations and the agents in the network resources. This information can be status information, counters, identifiers, etc. The SNMP manager continuously polls the agents for error and statistical data. The performance of the network will be dependent upon the setting of the polling interval. 1.9.2.
• • • Agents maintain vital information about their respective devices and networks. This information is stored in a MIB. The SNMP manager polls each agent for MIB information and stores and displays this information at the SNMP manager station. In this manner, the system administrator can manage the entire network from one management station. Agents also have the ability to send unsolicited data to the SNMP manager. This is called a trap. 1.9.
• System Profile Allows the systems administrator to define additional information for each system, such as location • System Monitor Provides system performance monitoring utilities, such as CPU, DASD, and Memory • Critical File Monitor Can generate alerts when critical files are changed or deleted • System Partition Access Allows an administrator to access the system partition on remote PS/2s • Predictive Failure Analysis Monitors PFA-enabled drives for errors • ServerGuard Service Can monitor
It also supports Novell NetWare. This means that there is a version of NetFinity Services which installs as a NetWare NLM on the file server and allows the server to be managed by a NetFinity Manager station. NetFinity Services can also be installed on a Windows NT server and used to manage this platform as well.
• File Transfer Can send/receive files to the remote system. • Remote Session Can open a remote console to the managed device. • Screen View Can take a snapshot of any screen on the remote device. • DMI Browser Enables you to view information about DMI compliant hardware and software. • Process Manager Enables you to start/stop/view processes running on the managed device. • Software Inventory Can scan remote device for installed software using a software dictionary .
Manager services and system module. This feature provide an extensive capability to merge dissimilar LANs into a single view of NetFinity managed assets. 1.9.3.4 DMI Support NetFinity is the first product available to customers that includes DMI support. NetFinity implementation of DMI support provides instrumentation from its System Information Tool to the DMI service layer for both OS/2 and Windows clients.

1.10.1 NetWare SFT III NetWare SFT III is a special version of the NetWare 3.x or 4.x NOS which adds a high degree of fault tolerance. It is composed of two servers, a primary and a secondary, which are mirrored together. To clients on the network, only the primary server appears to be active. The secondary server remains in the background; however, it maintains the same essential memory image and the same disk contents as the primary server.
Mirrored Server Link (MSL): The MSL is a bidirectional point-to-point connection that is used by the two servers to synchronize with each other. Information such as client requests and acknowledgments are passed back and forth on the MSL. After a failure has occurred, the MSL is used to synchronize the memory and disk of the failed server. As it is being brought back up, the active server transfers the entire contents of its MS Engine memory image to the formally inactive server.
Consequently, clients only receive reply packets from the primary server′ s IOEngine; this is the same IOEngine to which they sent the original request packet. The clients view the mirrored server as any other NetWare server. Clients send a single request packet and receive a single reply packet from the same address. The duplication of requests to the secondary IOEngine and synchronization of events to both server engines happens transparently to network clients.
The primary server sends the disk changes over the mirrored server link to update the repaired server and to mirror the contents of the disk. Disk mirroring occurs in the background during idle cycles. Scenario 2. Hardware fails in the secondary server: The primary server notifies the system administrator that the secondary server is down and that it is still the primary server. SFT III keeps track of any disk changes following the secondary server′s failure.
1.11 Uninterruptible Power Supply (UPS) Digital computers require a clean source of direct current (DC). It is the computer′s power supply which takes an alternating current (AC) from the input line and transforms it into clean DC voltages. However, problems on the input AC signal can often lead to DC voltages that are less than satisfactory for the digital circuits to operate properly. There are five main types of AC line problems that can cause trouble for a computer system: 1.
The primary service, however, that the UPS provides in the case of AC line problems is extra time. While a UPS can enable the server to continue operating even if there is a power loss, the primary benefit of a UPS is that the server software has time to ensure that all caches are written to disk, and to perform a tidy shutdown of the system. Some UPSs also offer an automated shutdown and reboot facility for network operating systems.
Flex Events is programmable such that when an event occurs, you can configure PowerChute to take certain actions.
Chapter 2. IBM PC Server Family Overview The IBM PC Server family contains three product lines which offer different features and capabilities: • The PC Server 300 series This series is targeted at small enterprises or workgroup LANs. These machines offer leading technology and are very price competitive. They are more limited in terms of upgrade and expansion capabilities than the other two lines in the family.

Chapter 3. Hardware Configuration The different technologies used to implement the PC Server family require different methods for configuration. Unfortunately, there is no one common configuration program which can be run on a machine to completely configure it. In most cases, multiple programs will need to be run in order to complete this process. This chapter gives instructions on using the various configuration programs and when to use each one. There are some model dependencies, however.

3.1 The Setup Program The setup program is used to configure system options on ISA and EISA machines. The system options include such things as diskette and hard disk options, video subsystem, and system memory. These parameters are controlled by system BIOS and, hence, need to be modified before the operating system boots. To access the setup program: 1. Turn on the server and watch the screen. The BIOS level appears. 2. When the message Press to enter SETUP appears, press F2. 3.
The Main panel contains fields which allow the user to: • • • • • Modify date and time Configure the diskette drives Configure the IDE disks Configure the video Enable/Disable level 2 system memory cache Notes: 1. Video BIOS Shadow This option allows the user to shadow the video BIOS into RAM for faster execution. The pre-installed SVGA Adapter supports this feature. 2. IDE Devices If no IDE DASD devices are installed, you must set all the IDE devices to none.
3.1.2.1 Advanced Menu - Boot Options By pressing the Enter key, a screen like that shown in Figure 25 will appear. Phoenix BIOS Setup - Copyright 1985-94 Phoenix Technologies Ltd.
If disabled, the system ignores the error and attempts to boot. 3.1.2.2 Advanced Menu - Peripherals To reach this menu: • • • Press ESC to quit the Boot options. Use the arrows keys to select the integrated peripherals option. Press Enter. A screen like the one in Figure 26 will appear: Phoenix BIOS Setup - Copyright 1985-94 Phoenix Technologies Ltd.
Memory Gap: Some ISA network adapters need to be mapped in system memory address space, normally at the upper end. Since the ISA bus is limited to 24-bit addressing (0-16 MB), systems with more than 16MB of memory installed will not accommodate these adapters. When enabled, this selection will remap system memory such that a gap is created between the addresses of 15 and 16MB. This gap is then used to map the I/O space on the adapter into this area. 3.1.
Enter password If you enter the wrong password, the following message appears on the screen, and you are prompted again: Incorrect password After 3 incorrect attempts, the following message appears and you must turn off the server and start again: System disabled Notes: 1. Before you set a supervisor password, you must first set your selectable drive-startup sequence. 2. Only the supervisor can change the supervisor password. 3.
Note BIOS of PCI/EISA servers is located in a Flash ROM on the motherboard. If necessary, it can be updated with a bootable diskette which has the new BIOS (.BIN) file. This file will be named: • • M4PE _Txx.BIN for DX2-66 models M5PE _Txx.BIN for Pentium models Where xx is the BIOS level as it appears when booting. For more information on how to obtain BIOS updates, please reference Appendix B, “Hardware Compatibility, Device Driver, and Software Patch Information” on page 199.
3.2 EISA Configuration Utility This utility is used when you add or remove an ISA or EISA adapter. We will use an example to illustrate the process. In our example we will add an Auto T/R 16/4 ISA adapter in slot 3 of a PC Server 320. The steps to complete the process are: 1. Boot with the EISA configuration utility diskette. 2.

Chapter 5. Performance Tuning To get the optimal performance from your NetWare server, you need to consider the performance of both the hardware and the software. In this chapter, we examine the general performance characteristics of file server hardware. We also discuss several performance monitoring tools. We then discuss the NetWare operating system and its relevant performance parameters. 5.
LAN adapters and fast disk subsystems. In contrast, database servers typically need fast processors (or multiple processors) and fast disk subsystems. Both file and database servers require large amounts of memory for operating system caching. Tuning system performance involves determining where the current bottleneck is and then alleviating this bottleneck.
Systematic measurements of server performance employing adequate resolution typically produce a graph shaped like the one shown in Figure 140 on page 169. The characteristics that shape this graph are important for understanding potential bottlenecks in a file server. Figure 140. File Server Performance - General Characteristics The horizontal axis shows the number of simultaneous active users. The vertical axis indicates server throughput, or number of transactions per second.
which represents the maximum server transactions per second or throughput rate. After the peak throughput is reached, the curve begins to slope downward. As the number of users is increased, the caching engine of the operating system begins to break down. The reduction in the disk cache hit rate is caused by the increasing amount of data that each additional user requests the server to access.
Figure 141. Differences in LAN Adapters Upgrading the disk subsystem will tend to flatten out the top of the curve as it will provide a higher sustainable data transfer rate. In most cases, the disk subsystem becomes the bottleneck when a large number of users becomes active. Since most disk subsystems are significantly slower than a cache-hit operation, the throughput curve begins to decline.
Figure 142. Differences in Disk Subsystems Improving performance of the disk subsystem transactions per second rate shown in Figure be to improve the disk cache hit rate. This is from the cache quicker, so that the amount of new data is increased. will usually prolong the maximum 142. The effect of a faster disk can because write-data can be flushed memory available for caching of 5.2 Performance Analysis Tools Using performance analysis tools is an effective method of understanding server performance.

Figure 143. MONITOR Utility The monitor utility allows you to check many important aspects of file server performance. It allows you check resource allocations and utilization of these resources. For example, you can: • List system modules loaded • View memory statistics • View tracked resources • Check status of LAN drivers and statistics • List active connections • Clear a connection • List open files • List record locks 5.2.2.
4. You are the given a choice of parameters to either view or set. In the following sections, we look at many of these parameters and make recommendations for setting them. Note Many of the set parameters can be adjusted from the server console while the server is up and running. However, several parameters must be set in either the AUTOEXEC.NCF or STARTUP.NCF files. The information displayed using the set command will indicate which parameters must be set in this way. 5.2.2.3 SERVMAN.
5.3.1 Disk Subsystem The file server disk subsystem contains the files which are accessed by the LAN workstations. The efficiency at which access is performed is directly related to the file server performance. The following section describes some of the findings of the IBM PC Server performance laboratory on the major factors that affect hard disk subsystem performance. 5.3.1.1 Block Size and Cache Buffer Size (NetWare 3.12) NetWare V3.
5.3.1.2 Block Size (NetWare 4.1) In all versions of NetWare prior to NetWare 3.X, the block allocation unit was fixed at 4KB. In NetWare 3.X, larger allocation units are possible, but they result in a lot of unused disk space at the end of files. For example, if the last part of a file took up 1KB of a 16KB block, the remaining 15KB was wasted. Sub-allocation is implemented in NetWare 4.1 to overcome the problem of wasted disk space due to under-allocated disk blocks.
NetWare 3.12 and 4.1: Default = 5 minutes 29.6 seconds Increasing the Turbo FAT re-use wait time helps ensure that the index structures are not flushed if the file is reused quickly. For example, a large database file might be accessed frequently throughout the day, with many file load and save operations. By increasing this parameter there is an increased likelihood of servicing the file request from a Turbo FAT index, thereby improving performance. 5.3.1.
5.3.1.5 File Caching File caching has the most affect on overall file server performance. Because accessing data from cache is much faster than accessing data from disk, the more data than can be held in cache, the better the server performance. Hence, the number of file cache buffers available can greatly impact server performance.
size is equal to 4096, the amount of memory used in megabytes can be calculated as follows: system memory used = (original cache buffers - total cache buffers) x cache buffer size (3000 - 2500) x 4096= 2,048,000 bytes (2MB) From this calculation, you can determine if the file server requires more memory, particularly when adding NLMs or changing the server configuration with set parameters.
5.3.1.7 Dirty Disk Cache Delay Time The dirty cache delay time controls the time taken to hold the write requests in the cache when the cache is not full. If your system has unused cache memory, and your typical server workload contains a high number of sequential write operations, then you may improve performance by increasing this value. The dirty cache delay time value can be set in the AUTOEXEC.NCF file using the following format: SET DIRTY DISK CACHE DELAY TIME=VALUE NetWare 3.12 and 4.
Attention Set this parameter to ON only if you are absolutely sure your backup strategy enables you to restore a file which has been deleted. 5.3.1.11 Enable Disk Read After Write Verify In NetWare, this read-after-write verify capability complements the hot fix function. This allows the system to prevent any file from being written to a bad disk block by attempting to read the data after it has been written to disk. NetWare′s read-after-write capability and hot fix function are implemented in software.
5.3.2.2 Packet Size Different network topologies will use different packet sizes. For example, a token-ring LAN adapter set to 16 Mbps can use packets of up to 4202 bytes. If the packet size is left at the network default value, which is 1514 bytes, this could unnecessarily slow down the LAN adapter performance. The reason for this is that it takes just as many instructions to process a small frame as it does a larger frame.
monitored using MONITOR.NLM. Use this value rather than the number of defined LAN users. For example: 1. For 40 LAN users with 2 LAN adapters in the file server: 40 (users) + ((10 x 2) LAN adapters) = 60 buffers minimum; set the maximum to 160. 2. For 100 LAN users with 4 LAN adapters in the file server: 100 (users) + ((10 x 4) LAN adapters) = 140 buffers minimum; set the maximum to 240.
Recommendation • • For networks without wide area (WAN) segments, set the maximum packet receive buffers to 300. For networks that use WANs, set the maximum packet receive buffers to 1000. This should be adequate to handle the additional buffering needed for WAN links. 5.3.2.4 New Packet Receive Buffer Wait Time The new packet receive buffer wait time is the wait time taken before spawning a new packet receive buffer. This parameter must be set in the AUTOEXEC.NCF file to change the value.
The size of the cache buffer pool is dynamic and determined by the amount of memory left over after the other pools have been allocated. As more buffers are allocated for NLMs and other system resources, this reduces the size of the cache buffers pool. Both the movable and non-movable pools return memory to the cache buffer pool when it is no longer needed. Checking the Allocation of Memory to Each Memory Pool: You can use the MONITOR.NLM utility to view the allocation of system memory by pool.
5.3.4 Memory Requirements The following sections present some guidelines for calulating total server memory requirements for both the NetWare V3.12 and V4.1 environments. 5.3.4.1 Calculating Server Memory Requirements (V3.12) To calculate the total system memory required, use the following guidelines: 1. Allocate a m i n i m u m of 4MB of RAM for loading the operating system, disk drivers, LAN drivers and the INSTALL.NLM. 2.
processing, this is an indication that the LAN adapter could be a bottleneck in the file server. In this case, the LAN adapter could be upgraded or another one added to balance the LAN load and use the system processor more efficiently. The use of bus mastering LAN adapters and disk controllers also helps to spread the load on the file server more evenly and thereby uses the system processor in a more efficient manner.

Appendix B. Hardware Compatibility, Device Driver, and Software Patch Information One of the challenges that LAN administrators face is ensuring that the adapters they want to use are supported and then finding the latest level of device drivers for these adapters. Another problem they face is trying to find information about known software bugs and their corresponding fixes. This appendix is included to help readers solve these problems. B.
Figure 145. Sample Compatibility Report Showing Ethernet LAN Adapters In addition, it contains reports by NOS and by machine and model number which shows the testing done to certify the hardware against the operating system. These reports show detailed information on hardware configurations, adapters, device drivers, and code levels used in the testing. B.
For OEM adapters, many manufactures have web and FTP sites which work very similar to the process outlined above. There is a one very useful web site which maintains an index to many OEM web sites which have device drivers for many popular boards. The site is called the LAN Drivers Page and the URL for this site is: • http://sunsite.unc.edu/ ∼ towfiq/lan-drivers.html B.
