Note: The following sample configurations are for illustration only and may not be suitable for any specific customer installation. Contact your IBM Business Partner
or IBM Marketing Representative for assistance with your specific configuration requirements.
Internet Server
An Internet server handles all requests from the Internet (Intranet or Extranet). Usually this type of server has the same characteristics as a file server. The main
difference is that an Internet server uses a different protocol (TCP/IP vs NETBEUI or IPX/SPX) and often needs to perform an extra security check (firewall). In the
case of an Internet server, the server itself communicates primarily with one client, the Internet Service Provider (ISP), instead of many clients as applies to a file
server.
With this in mind, the xSeries 232 was selected to provide an affordable price point for the growing Internet server market with two-way Pentium processing, 512MB
of system memory (expandable to 4GB), availability features such as RAID-protected internal hot-swap storage and power protection with an APC Smart-UPS.
The network configuration depends on the method that will be used to connect the server to the Internet. Usually fast Ethernet routers are used, but if other methods
are preferable, you can add the appropriate adapter. The configuration includes a tape back-up unit for secure storage of critical data in the event of a system or
storage media failure.
File and Print Server
A small business or departmental server is usually required to perform all typical server functions while servicing up to 100 users in a normal workgroup computing
environment, but doesn’t require the high-end performance and fault-tolerance properties of larger servers.
The sample configuration above consists of an xSeries 232 with 768MB of memory (expandable to 4GB) and 54.6GB of RAID-protected hard disk drive space. It has
enough processor power and memory to run most current network operating systems comfortably and enough hard disk drive space to store a significant amount of
data with additional external storage expansion still available. Demanding network traffic is effectively handled by the standard 100Mbps Ethernet connection.
This configuration also includes a tape back-up unit, monitor, and a UPS to protect the system during power surges and outages.
Note: Additional power is not required when installing a SCSI device in bay A or B. If adding additional power supplies to base models for redundancy, removal of the standard 385W power
supply is required before adding both Hot-Swap Power Conversion Kit (P/N 24P3513) and two or three optional 250W Hot-Swap Redundant Power Supplies (P/N 33L3760). Models shipped
standard with redundant power contain two hot-swap 250W power supplies (maximum of three). An optional SCSI cable is required for attachment of media bay devices to the Ultra160
controller B. No external SCSI port is available. External tape enclosures are supported by PCI Wide Ultra160 SCSI Adapter (P/N 19K4646) which has an external 0.8mm VHDCI connector.
1. Internal tape drives require the two-drop multi-mode terminated LVD SCSI cable included with the Media Bay Tray and LVD Cable Kit (P/N 10K2340).
2. LVD support for LVD devices installed in a NetMEDIA Storage Expansion Unit EL (P/N 3551001) requires replacement of the standard single-ended internal cables with one or more
(depending on configuration) cables from Media Bay Tray and LVD Cable Kit (P/N 10K2340) which contains a single two-drop multi-mode terminated cable. If the standard cables are used
for attachment to LVD devices, single-ended SCSI rules and bus speeds apply.
3. Requires 68-pin External Multimode LVD/SE SCSI terminator (P/N 00N7956).
4. Tape library attributes and prerequisites are located in Appendix B: Tape Library Attributes.
5. Provides a black desktop 133mm (5.25in) half-high (HH) tape enclosure. Connector is configurable as 50-pin Centronix or 68-pin high density. Requires either tape drive self-termination
or 68-pin External Multimode LVD/SE SCSI Terminator (P/N 00N7956).
6. NetMEDIA Storage Expansion Unit EL (P/N 3551001) is a black 3U, 19in rack mountable tape enclosure which includes two full-high (FH) or four half-high (HH) extended length 133mm
(5.25in) bays, two external 0.8mm VHDCI connectors and two internal four-drop single-ended terminated 16-bit SCSI cables for device attachment. Two power supplies and two power
cords are also included. Tip: The front rail clips will need to be reversed and screwed in from behind to secure the unit in a 930842x rack.
7. NetMEDIA Systems Management Adapter (P/N 10L7113) may be installed in a 3551001 to provide repeater function, LVDS interface, aggregate cable lengths up to 12m when attached to
an LVD SCSI controller, and auto-termination when the 3551001 is powered off. External connector is 0.8mm VHDCI.
8. IBM eServer xSeries Hot-Swap Power Conversion Kit (P/N 24P3513) includes a hot-swap power backplane. Required when upgrading standard power on base models,
which are shipped with a single 385W power supply that must be removed when adding this option.
Note: Additional tape attributes can be found in Appendix A: Tape Drive Attributes.
