IBM System Storage DR550 Version 3.0 ------ 17 March 2006 Page 7

Hardware Overview

The DR550 includes one or two IBM System P5 520 servers running AIX® 5.3. When configured with two 520 servers, the servers are setup in an HACMP™ 5.3 configuration. Both P5 520s have the same hardware configuration. When configured with one 520 server, no HACMP software is included.

IBM System P5 520

The IBM System P5 520 (referred to hereafter as the P5 520 when discussing the DR550) is a cost- effective, high performance, space-efficient server that uses advanced IBM technology. The P5 520 uses the POWER5+ microprocessor, and is designed for use in LAN clustered environments.

The P5 520 is a member of the symmetric multiprocessing (SMP) UNIX servers from IBM. The P5

520(product number 9131-52A) is a 4-EIA (4U), 19-inch rack-mounted server. The P5 520 is configured as a 2-core system with 1.9 GHz processors. The total system memory installed is 1024 MB.

The P5 520 includes six hot-plug PCI-X slots, an integrated dual channel Ultra320 SCSI controller, two 10/100/1000 Mbps integrated Ethernet controllers, and eight front-accessible disk bays supporting hot-swappable disks (two are populated with 36.4 GB Ultra3 10K RPM disk drives). These disk bays are designed to provide high system availability and growth by allowing the removal or addition of disk drives without disrupting service. The internal disk storage is configured as mirrored disk for high availability.

•Media – dev1 – Slimline DVD-RAM (FC 1993)

•SCSI tape drive (not included)

From the back of the server, the following ports and slots are included.

PCI-X slots: The P5 520 provides multiple hot-plug PCI-X slots. The number and type of adapters installed is dependent on the configuration selected.
