IBM System p5 520 and 520Q Technical Overview and Introduction

The primary rules that you should follow when you mount the server into a rack are:

򐂰

The p5-520 or p5-520Q is designed to be placed at any location in the rack. For rack 
stability, we advise that you start filling a rack from the bottom.

򐂰

Any remaining space in the rack can be used to install other systems or peripherals, 
provided that the maximum permissible weight of the rack is not exceeded and the 
installation rules for these devices are followed.

򐂰

Before placing or sliding a p5-520 or p5-520Q into the service position, it is essential that 
you have followed the rack manufacturer’s safety instructions regarding rack stability. 

The availability of 14-foot, 9-foot, and 6-foot jumper cords (between the drawer and the PDU) 
provides several options to ensure that all cables are accounted for inside the rack space.

Depending on the current implementation and future enhancements of additional 7311 Model 
D20 drawers that are connected to the system, Table 1-12 shows examples of the minimum 
and maximum configurations for different combinations of servers and attached 7311 Model 
D20 I/O drawers.

This section highlights some solutions available to provide a single point of management for 
environments composed of multiple p5-520 or p5-520Q servers or other IBM System p5 
servers.

The IBM 7212 Model 103 is designed to provide efficient and convenient storage expansion 
capabilities for selected System p servers. The IBM 7212 Model 103 is a 1U rack-mountable 
option to be installed in a standard 19-inch rack using an optional rack-mount hardware 
feature kit. The 7212 Model 103 has two bays that can accommodate any of the following 
storage drive features:

Digital Data Storage (DDS) Gen 5 DAT72 Tape Drive provides a physical storage capacity 
of 36 GB (72 GB with 2:1 compression) per data cartridge.

򐂰

VXA-2 Tape Drive comes with a media capacity of up to 80 GB (160 GB with 2:1 
compression) physical data storage capacity per cartridge.

򐂰

VXA-320 Tape Drive comes with a media physical capacity of up to 160 GB (320 GB with 
2:1 compression) physical data storage capacity per cartridge.

򐂰

Half-High LTO-2 Tape Drive comes with media physical capacity of up to 200 GB (400 GB 
with 2:1 compression) data storage per Ultrium 2 cartridge and a sustained data transfer 
rate of 24.0 MB per second (48 MB per second with 2:1 compression). In addition to
