IBM XSERIES 220

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 normal file server. The

main difference is that an Internet server talks a different language (TCP/IP vs NETBEUI or IPX/SPX) and often needs to do an extra security check (firewall). In the

case of an Internet server, the server itself talks mostly to just one client, the Internet Service Provider (ISP), instead of many clients as a file server does.

With this is mind, the xSeries 200 was selected to provide an affordable price point for the growing Internet server market with two-way Pentium III processing,

256MB of system memory (expandable to 4GB), 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 used you can add the appropriate adapter. The configuration includes a tape backup unit for secure backup of critical data in the event of a system or storage

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 220 with 256MB of memory and 54.6GB of HDD 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 backup unit, monitor, and a UPS to keep the system protected during power surges and outages.

Note: All models include an Ultra160 SCSI controller with a five-drop multi-mode terminated LVD SCSI cable. Single-ended devices attached to this cable will limit the entire SCSI bus to

single-ended performance. All tape drives and external tape enclosures are supported by PCI Wide Ultra160 SCSI Adapter (P/N 19K4646) which includes a five-drop multi-mode

terminated LVD SCSI cable and an external 0.8-mm VHDCI connector.

1. To determine cable requirements, note the tape drive’s SCSI interface, the appropriate SCSI controller from the system configurator section, and the desired enclosure, then refer to

Appendix D: Cables - Storage Units - Controllers.

2.This single-ended device will limit the SCSI bus to which it is attached to Ultra SCSI speeds. To provide a dedicated tape SCSI bus, install PCI Wide ultra160 SCSI Adapter (P/N

19K4646) which includes a five-drop multi-mode LVD SCSI cable.

3. RAID configurations, where the standard SCSI cable is attached to a RAID adapter, require the two-drop multi-mode terminated LVD SCSI cable included with Media Bay Tray and LVD

Cable Kit (P/N 10K2340) for attachment of the tape drive to the standard SCSI controller.

4. Requires 68-pin External Multimode LVD/SE SCSI Terminator (P/N 00N7956)

5. 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 mult-mode terminated cable. If the standard cables are

used for attachment to LVD devices, single-ended SCSI rules and bus speeds apply.

6. 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).

7. 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 68-pin high density 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.

8. 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.
