Plug the Controller into any 32-bit or 64-bit PCI Slot Manual No.
Installation Process Preparing the SCSI Drives To prepare the drives for installation, follow these steps: 1. Remove any terminators attached to the drive or set any drive termination jumpers to the disabled position. 2. Set the SCSI IDs on the drives. 3. Enable term power on the drives. Refer to the drive manual for specific information about drive configuration settings. Installing Cables and Setting Termination Please refer to Table 2-3 on page 2-15 for SCSI Formats and Bus Length requirements. 4.
Installation ☛ Note In order to ensure an error free environment, the proper cable type designed for a certain SCSI speed must be used, please refer to Table 2-3 on page 2-15. ☛ Note To avoid problems caused by mixing drive types, please refer to “Limitations on Mixing SCSI Drives” on page 2-16. SCSI Termination Each end of a SCSI bus must be terminated to maintain proper voltage levels for SCSI control and data signals. The device used for this purpose is called a terminator.
Installation Process 1. Termination - Only Internal or Only External Devices Check that the drive channel is properly terminated according to drawings below, or skip to Step 2 if using both internal and external devices. The AcceleRAID 170 is equipped with automatic SCSI termination circuitry which handles automatic enabling and disabling of on-board termination. For example, if the controller is at the end of the SCSI bus, it automatically enables on-board termination.
Installation 2. Termination - Both Internal and External Devices Check that the drive channel is properly terminated according to the drawing below. If the controller is in the middle of the SCSI bus, it automatically disables on-board termination. If some SCSI devices on the channel are connected to the internal connector, and some are connected to the external connector, on the same channel, the two ends of the SCSI bus farthest from the controller must each be terminated.
Installation Process Setting SCSI Device IDs 4. Set the SCSI ID on the disk drives; ID 7 is reserved for the controller. See Figure 2-12. ☛ Note Each drive must have a unique ID chosen from 0 through 6 or 8 through 15. Be careful not to duplicate a drive address. Remember: ID 7 is reserved for the controller; therefore, it cannot be used as a disk drive ID. ID’s from 0 through 6 are usually for Narrow, 8-bit devices.
Installation SCSI Cabling The controller supports one Ultra 160 SCSI channel which can support up to 15 SCSI devices (plus the controller itself). LVD Mode The controller supports Ultra 160 SCSI with LVD. If all drives attached to a controller drive channel support Ultra 160 SCSI with LVD, then that channel will operate at a maximum of 160MB/s burst speed. This setup allows a maximum SCSI bus length of up to 12 meters.
Limitations on Mixing SCSI Drives Limitations on Mixing SCSI Drives Narrow with Wide SCSI Drives If you mix narrow and wide SCSI devices on the controller, use a terminator that does not terminate the upper eight bits, and be sure to properly terminate the end of the bus with either a 16-bit terminator or a 16-bit device that has termination enabled.
Chapter 3 Controller Start-up This chapter describes: • BIOS Options • BIOS Configuration Utility (RAID EzAssist) • Operating System, Device Drivers, GAM • What to Check in Case of Problems This chapter describes the AcceleRAID 170 RAID controller start-up procedures and messages produced by the BIOS during start-up or re-boot. This chapter also explains three BIOS options that are available for configuring controller operation.
BIOS Options option.
Controller Start-up Setting BIOS Options The available BIOS options are: • BIOS disabled / enabled • CD-ROM boot disabled / enabled • 2GB / 8GB drive geometry BIOS Disable or Enable This option must be enabled in order to toggle the CD-ROM boot parameter shown in the BIOS Options menu. The BIOS must also be enabled in order to boot from any device (e.g., CD-ROM) or system drive configured on the controller, or to access any DOS partition on any drive configured on the controller.
BIOS Options Enable 8 GByte or 2 GByte Drives This setting affects how the BIOS reads the disk drives for the boot partition. Drive geometries can be toggled between 8 GB and 2 GB. The default is 2 GB. When the drive geometry is changed, the drive should be formatted at the operating system level. Caution Changing this setting after data has been stored will make the data unreadable. If you have already configured your array and have stored data, you should not change this setting.
Controller Start-up ☛ Note In the event that the RAID controller needs to be replaced, the current drive geometry will be restored from the configuration on disk (COD). BIOS Configuration Utility (RAID EzAssist) RAID EzAssist is the on-board BIOS Configuration Utility used to build several types of RAID configurations. Refer to the RAID EzAssist Configuration Utility User Reference Guide or RAID EzAssist Configuration Utility Quick Configuration Guide.
Global Array Manager (GAM) Client Global Array Manager (GAM) Client The controller can be configured using GAM. GAM can also be used from the server or a system client to monitor status and verify data integrity of disks connected to the controller while the system and disks are running. For details on how to install and run GAM client, refer to the Global Array Manager Client Software Installation Guide and User Manual.

System Reboot or Power Down B-4 AcceleRAID 170 Installation Guide
Appendix C PCI Hot Plug Introduction PCI Hot Plug is a feature that allows a PCI card to be replaced while the host system is still running. The term “Hot Plug” is somewhat misleading; the PCI card cannot simply be pulled out of the host system while the card is operating without risk to the card, the system, and the data on the system. In order to replace a Hot Plug PCI card, a software command must be invoked to power off the card slot before the card can be removed.
Implementation • odineb.nlm - This is a module combining the Open Data-link interface and the Novell Event Bus (NEB). The NEB controls the device drivers through the Open Data-link. If the NetWare installation process determines that the server supports PCI Hot Plug and detects the appropriate driver, the installation process adds the following two LOAD commands to the autoexec.ncf file: • LOAD sys:\system\driver_name This command loads the bus driver (for Compaq, this is cpqsbd.nlm).
PCI Hot Plug Windows NT Windows NT requires additional software from the vendor who makes the system. Since this software is not a part of NT, the software needs to be installed after the operating system is loaded. Refer to your system or server vendor's PCI Hot Plug documentation. Caution GAM drivers can stop PCI Hot Plug Boards from unloading. If this problem occurs, stop GAM and unload the GAM drivers before attempting to unload the PCI Hot Plug controller.
Implementation the PCI Hot Plug capability. No additional software is required. Please refer to the Windows XP or .NET 32-bit documentation for instructions on how to use the PCI Hot Plug feature.
Appendix D Enclosure Management Introduction Mylex’s AcceleRAID controllers support the industry standard enclosure management protocol SCSI Accessed Fault-Tolerant Enclosures (SAF-TE). This feature allows the host to monitor drive enclosures and detect certain faults or operating environment conditions. The host can make a decision to shut down the system or issue a warning based on the type of fault detected.
SES SES The AcceleRAID 170 supports SES (SCSI Enclosure System) cabinets. Please refer to the documentation supplied with your SES enclosure cabinet for details on how to take advantage of this feature.
Glossary AcceleRAID™ The AcceleRAID family features high performance, cost effective Ultra SCSI/Ultra2 SCSI LVD and Ultra 160 SCSI to PCI RAID controllers and adapters for high-end desktops, workstations, and entry level and mid range servers. AcceleRAID controllers support PCI-based motherboards with embedded SCSI chips and systems that have a PCI expansion slot designated for add-in RAID controllers. The AcceleRAID family consists of the 150, 200, 250, 352, 160, 170, and 170LP controllers.
Automatic Rebuild Mylex controllers provide automatic rebuild capabilities in the event of a physical disk drive failure. The controller performs a rebuild operation automatically when a disk drive fails and both of the following conditions are true: A standby or hot spare disk drive of identical or larger size is found attached to the same controller; All system drives that are dependent on the failed disk drive are configured as a redundant array: RAID 1, RAID 3, RAID 5, or RAID 0+1.
Glossary Bus A set of conductors that connect the functional units in a computer and are the channels through which data is transferred. There are several types of bus channels, including serial, parallel, PCI, ISA, EISA, and MCA. See also I/O Bus. Cables The physical wires (copper or fibre optic) over which electrical signals are transmitted. Cables are used to connect peripherals (such as disk arrays) to computers and servers or to connect peripherals or components to each other.
Channel Any path used for the transfer of data and control of information between storage devices and a storage controller or I/O adapter. Also refers to one SCSI bus on a disk array controller. Each disk array controller provides at least one channel. Conservative Cache An operating mode in which system drives configured with the write-back caching policy are treated as though they were configured for write-through operation and the cache is flushed.
Glossary Disk A non-volatile, randomly addressable, re-writable data storage device, including rotating magnetic and optical disks as well as solid-state disks or other electronic storage elements. Disk Array A collection of disks from one or more commonly accessible disk systems. Disk arrays, also known as RAID, allow disk drives to be used together to improve fault tolerance, performance, or both. Disk arrays are commonly used on servers and are becoming more popular on desktops and workstations.
active controllers (also called Active/Active controllers) are connected to the same set of devices and provide a combination of higher I/O performance and greater failure tolerance than a single controller. ECC Error Correcting Code, a method of generating redundant information which can be used to detect and correct errors in stored or transmitted data.
Glossary eXtremeRAID 1100, 2000, and 3000 provide the highest performance and most flexible RAID solution available today. Failback Restoring a failed system component’s share of a load to a replacement component. Failover A mode of operation for failure tolerant systems in which a component has failed and a redundant component has assumed its functions. Failover Port A fibre channel port capable of assuming I/O requests for another, failed port on the loop.
Gigabyte 230 (1,073,741,824) bytes. Abbreviated as G or GB. Global Array Manager (GAM) A Mylex RAID management utility that allows a system administrator to configure, monitor, and manage network RAID storage from anywhere in the world. GAM can communicate critical notification via e-mail, fax, pager, SNMP or the launching of an application. GAM is everything needed to manage Mylex PCI RAID Controllers, SCSI Host Adapters, and External RAID Controllers.
Glossary controller to “rebuild” the data on the new drive, all without interrupting system operations. Once the rebuild is complete, the controller will be brought back into a fault tolerant state. See also Hot Swap. Hot Spare A physical disk drive not part of a system drive that the controller can use to automatically rebuild a critical system drive. The hot spare drive must have at least as much capacity as the largest disk drive in the array or the rebuild may not start. See also Hot Standby.
I/O Input/Output, the transmission of information between an external source and the computer. I/O Bus Any path used for the transfer of data and control information between I/O adapters and storage controllers or storage devices. See also Bus. I2O Intelligent Input/Output, a driver that uses special I/O processes to eliminate I/O bottlenecks. The processes deal with interrupt handling, buffering, and data transfer.
Glossary Logical Drive States A logical (system) drive can be Online, Critical, or Offline. Notice that the term “online” is used for both physical and logical drives. LVD Low Voltage Differential, a form of SCSI signaling introduced with Ultra2 SCSI (Fast40 SCSI) uses data high and data low signal lines to increase transmission distances over those of single-ended (conventional SCSI signaling) lines. LVD allows for cable lengths of up to 12 meters (approximately 39 feet) with up to 15 devices.
Mirroring Refers to the complete duplication of data on one disk drive to another disk drive, this duplication occurs simultaneously with each write operation: each disk will be the mirror image of the other (also known as RAID Level 1, see RAID levels). All Mylex RAID controllers support mirroring. M.O.R.E. Mylex Online RAID Expansion, an advanced configuration mode that allows expansion of any unconfigured or hot spare drive into the expandable drive group while the controller is online with the host.
Glossary Offline A Logical Drive is in an “offline” state if no data can be read from it or written to it. Offline does not apply to physical disk drives. System commands issued to offline logical drives are returned with an error status; no operations can be performed on offline logical drives. See also Logical Drive States, Online, and Critical. Online A Logical Drive is in an “online” state if all of its participating SCSI drives have power and are operational.
Physical Device Any device connected to some kind of hardware. For example, SCSI disk, fibre disk, network disk, RAM disk, etc. Physical Disk Drive A single hard disk drive. Each physical disk drive is assigned a unique identification address. PROM Programmable Read-Only Memory, memory that users with appropriate instructions can reprogram. Protocol A special set of rules for transmitting data between two devices in a telecommunication connection.
Glossary RAID Levels Mylex disk array controllers support four RAID Advisory Board approved (RAID 0, RAID 1, RAID 3, and RAID 5), two special (RAID 0+1, and JBOD), and three spanned (RAID 10, 30, and 50) RAID levels. All DAC960, AcceleRAID, and eXtremeRAID series controllers support these RAID levels. Level 0: Provides block “striping” across multiple drives, yielding higher performance than is possible with individual drives. This level does not provide any redundancy.
RAID Migration A feature in RAID subsystems that allows for changing a RAID level to another level without powering down the system. RAM Random Access Memory, the "built-in" readable and writable data storage that comes with (or can be added to) a computer. RISC Reduced Instruction Set Computing, architecture for an application-specific processor. RJ-11, RJ-45 Registered Jacks (sometimes described as RJ-XX), a series of telephone connection interfaces (receptacle and plug) that are registered with the U.
Glossary enclosure itself is treated as simply another device on the SCSI bus. Many other leading server, storage, and RAID controller manufacturers worldwide have endorsed the SAF-TE specification. Products compliant with the SAF-TE specification will reduce the cost of managing storage enclosures, making it easier for a LAN administrator to obtain base-level fault-tolerant alert notification and status information. All Mylex RAID controllers feature SAF-TE.
Offline: A SCSI disk drive is in a “offline” state if it is not present, if it is present but not powered on, or if it failed to operate properly and was “offline” by the controller. When the controller detects a failure on a disk, it “kills” that disk by changing its state to “offline.” An “offline” SCSI drive can also be present and powered on, but a SCSI drive in a “offline” state does not participate in any I/O activity; no commands are issued to dead drives.
Glossary reported, conservative cache is enabled and all system drives are switched to write-through cache. Primarily used in fibre enclosures. SIMM Single In-line Memory Module, RAM packed on a small circuit board with a defined edge connector. Two SIMMs are required for a 64-bit memory path on a Pentium processor. See also DIMM. SISL See SCSI Interrupt Steering Logic (SISL).
To use the standby rebuild feature, you should always maintain a standby SCSI disk in your system. When a disk fails, the standby disk will automatically replace the failed drive and the data will be rebuilt. The system administrator can disconnect and remove the bad disk and replace it with a new disk. The administrator can then make this new disk a standby. The standby replacement table has a limit of 8 automatic replacements in any session (from power-on/reset to the next power-off/reset).
Glossary drive 1, block 2 on SCSI drive 2, block 3 on SCSI drive 3, block 4 on SCSI drive 1, block 5 on SCSI drive 2, and so on. This storage method increases the disk system throughput by ensuring a balanced load among all drives. Sustained Data Transfer Rate A rate of data transfer defined for continuous operation at a maximum speed level.
Ultra SCSI (Fast 20 SCSI) A high performance SCSI protocol that has a bus speed of 20 Megabytes per second in the Narrow SCSI configuration and 40 MB in the Wide SCSI (Fast 20 Wide SCSI) configuration. Ultra Wide SCSI 16-bit wide Ultra SCSI (IS devices), double the speed of narrow SCSI. Ultra2 SCSI (Fast 40 SCSI) A higher performance SCSI protocol than Ultra SCSI.
