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 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 one client, the Internet Service Provider (ISP), instead of many clients as a file server does.

With this in mind, the xSeries 230 was selected to provide an affordable price point for the growing Internet server market, 256MB of system memory (expandable to

4GB, and 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 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 230 with 256MB of memory (expandable to 4GB) and 27.3GB of RAID-protected HDD space. It has enough

processor power and memory to run most current network operating systems comfortably and enough HDD 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.

The configuration also includes a tape backup unit, monitor, and a UPS to keep the system protected during power surges and outages.

Note: Additional power may be required when installing a SCSI device in bay A or B. Configurations exceeding four SL hot-swap hard disk drives and two PCI adapters are recommended

to include both Hot-Swap Power Supply Expansion Kit (P/N 37L6881) and at least one optional 250W Hot-Swap Redundant Power Supply (P/N 33L3760). An optional SCSI cable is required

for attachment of media bay devices to 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 either Media Bay Tray and LVD Cable Kit (P/N 10K2340) or Hot-Swap Power Supply

Expansion Kit (P/N 37L6881).

2. If installed in a rack, a fixed shelf is required. Allow an additional 1U for the fixed shelf. One unit only per shelf is supported.

3. 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.

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

5. Tape library attributes and prerequisites are located in Appendix B: Tape Library Attributes.

6. Install in second drive bay of 3600 Series LTO Tape Libraries or in either of the two bays of 3600 Series 2-Drive 20-Cartridge Expander Module to increase performance. Includes an LTO

(Ultrium) drive and a one-meter external LVD SCSI cable.

7. 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).

8. 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.

9. 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.

10. Hot-Swap Power Supply Expansion Kit (P/N 37L6881) includes a hot-swap power backplane and two-drop multi-mode terminated LVD SCSI cable. Required when installing a second

power supply.

Note: Additional tape attributes can be found in Appendix A: Tape Drive Attributes.
