IBM System p5 520 and 520Q Technical Overview and Introduction
Three non-hot-swappable media bays are used to accommodate additional devices. Two
media bays only accept slim-line media devices, such as DVD-ROM or DVD-RAM drives, and
one half-height bay is used for a tape drive. The rack-mount model also has I/O extension
capability using the RIO-2 bus that allows attachment of the 7311 Model D20 I/O drawers.
For partitioning, we recommend an HMC. Dynamic LPAR is supported on the p5-520 and
p5-520Q servers, allowing up to two logical partitions. In addition, the optional Advanced
POWER™ Virtualization feature supports up to 40 micro-partitions using Micro-Partitioning™
technology. The Integrated Virtualization Manager provides partition management in settings
where an HMC is unavailable or not desired.
Additional reliability and availability features include redundant hot-swappable cooling fans
and redundant power supplies. Along with these components, the p5-520 and p5-520Q are
designed to provide an extensive set of reliability, availability, and serviceability (RAS)
features that include a dual service processor, fault isolation, recovery from errors without
stopping the system, avoidance of recurring failures, and predictive failure analysis.
The p5-520 and p5-520Q are backed by a three-year limited warranty. Check with your IBM
representative for particular warranty availability in your region.
