IBM eServer p5 Model 520Q Express

Linux® & UNIX processing consolidation & power for small- to medium-sized business & branch operations

Utilizing IBM’s new Quad-Core Module (QCM) technology, the System p5 520Q Express servers are optimized for Java™ & web applications, making it ideal for the most demanding eCommerce and Web infrastructure applications.

Enhanced Scalability

QCM technology delivers 4-core processing power for the p520Q Express systems. This unique infrastructure is designed to increase system throughput and memory bandwidth, and is ideal for compute-intensive applications. Each p520Q Express servers comes with a four-core QCM, and you can choose between 1.5GHz or 1.65GHz POWER5+ processors.

In addition the System p5 520Q server can:

• scale up to 64GB of DDR2 memory
• support up to 2.4TB internal disk
• have up to 4 I/O drawers, which can provide up to 16.8TB of disk and up to 28 hot-plug PCI-X slots

64-bit POWER5+ processing power

IBM’s fifth generation of POWER technology delivers 64-bit computing with advanced features like simultaneous multithreading, which allows you to run two concurrent application threads on the same processor.

Virtualization Engine™

The IBM System p5 520Q Express model comes with IBM’s Virtualization Standard, allowing you to utilize the server to consolidate multiple UNIX and Linux workloads on one system. In addition, Dynamic LPAR further enhances the virtualization capabilities of your p510Q, allowing you to allocate and re-allocate systems resources as needed. without rebooting.

Virtual LAN comes with the Virtualization Engine, and delivers a fast interconnect in between your partitions, speeding internal communications to memory speeds.

Advanced POWER Virtualization

This module is optional on the p520Q Express platform, and offers features like Micro-Partitioning and Virtual I/O Server (VIOS). These features further maximize the utilization of your system resources.

Micro-Partitioning lets you define partitions as small as 1/10th of a processor, and changed in increments as small as 1/100th of a processor.

VIOS for the System p5 520Q Express increases the amount of systems resources you can share between partitions, such as expensive disk drives. The VIOS includes the Integrated Virtualization Manager, a browser-based applications that greatly eases the amount of time and effort required to create and manage virtual devices & partitions.

Packaging & Configuration Flexibility

All of the System p5 520Q Express systems can be packaged as a deskside or rackmount system, you can implement this p5 system as a versatile departmental or branch server, or use it as a scalable server in your datacenter.

Reliability, Availability, Security (RAS)

The p520Q servers include many of the same RAS features included with the higher-end System p5 machines. Some of the RAS capabilities include:

• Chipkill™ ECC & bit-steering memory
• hot-swappable, redundant components
• dynamic deallocation of system components
• a sophisticated service processor

The System p5 520Q servers design logical partitions to be shielded from one another to prevent applications running in one partition from violating security policies across partitions, for additional security.
