Hardware Overview
The DR550 SMB includes one IBM eServer P5 520 server running AIX® 5.2, a flat panel monitor
and keyboard, and when configured for tape attachment, a Fibre Channel SAN Switch is included in
the offering. No clustering option is available.
IBM eServer P5 520
The IBM eServer POWER5 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 9111-520) is a 4-EIA (4U), 19-inch rack-mounted server (you will need ton
provide space in an existing rack or purchase a new rack separately). The P5 520 is configured with
a 1-way 1.5 GHz processor. The total system memory installed is 512 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 (all eight are populated with 146 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 uses RAID-5 protection
for high availability.
In addition to the disk drives, there are also 3 media bays available.
• Media - dev0 – not used for DR550
• Media – dev1 – Slimline DVD-RAM (FC 5751)
• 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.
Disk only version:
The following adapters are installed.
• One – POWER GXT135P Graphics Accelerator with Digital support adapter (FC 2849)
o Used to connect to the integrated monitor
The customer will need to choose one of the following adapters for network connection.
• For fiber optic connections, choose the single Port Gigabit Ethernet-SX PCI-X adapter
(feature code 5701).
• For copper connections, use the integrated 10/100/1000 Ethernet ports on the p520 server.
Disk and Tape ready version:
The following adapters are installed.
• One 2 Gigabit Fibre Channel PCI-X adapters (two for connections to the internal SAN for
disk attachment and one for connection to the internal SAN for tape attachment) (FC 5716)
• One – POWER GXT135P Graphics Accelerator with Digital support adapter (FC 2849)
o Used to connect to the integrated monitor
The customer will need to choose one of the following adapters for network connection.
• For fiber optic connections, choose the single Port Gigabit Ethernet-SX PCI-X adapter
(feature code 5701).
• For copper connections, use the integrated 10/100/1000 Ethernet ports on the p520 server.
I/O ports: The P5 520 includes several native I/O ports as part of the basic configuration:
