POWER5+ processor core
*Designed to provide excellent application performance and high reliability
*Includes simultaneous multithreading to help increase commercial system performance and processor utilization
High memory / I/O bandwidth
*Fast processors wait less for data to be moved through the system
*Delivers data faster for the needs of HPC and other memory-intensive applications
1U packaging
*19-inch rack-mount model for high-density configuration
Shared processor pool*
*Provides the ability to transparently share processing power between partitions
*Helps balance processing power and make sure the high priority partitions get the processor cycles they need
*Allows each processor in the shared processor pool to be split into as many as 10 partitions
*Fine tune processing power to match workloads
Virtual I/O Server*
*Helps save cost and ease systems administration by sharing expensive resources
Virtual LAN*
*Helps speed internal communication between partitions at memory speeds
Dynamic logical partitioning*
*Allows reallocation of system resources without rebooting affected partitions
*Offers greater flexibility in using available capacity and more rapidly matching resources to changing business requirements
Mainframe-inspired RAS
*Delivers exceptional system availability using features usually found on much larger, more expensive systems including service processor, IBM Chipkill™ memory, First Failure Data Capture, dynamic deallocation of selected system resources, hot-plug PCI-X slots, hot-swappable disk bays, redundant hot-plug cooling, selective dynamic firmware updates and more
Multiple operating system support
*Allows clients the flexibility to select the right operating system and the right application to meet their needs
*Provides the ability to expand application choices to include many open source applications
