IBM pSeries p660-6M1 Server

IBM pSeries p660-6M1 Server Overview

Copper-based, SOI-based SMP processors
*Provide significant performance increases over the predecessor Model M80
*Improve reliability while reducing the heat produced
Capacity Upgrade on Demand
*Offers flexibility to immediately and cost-effectively add processing capacity
64-bit system architecture
*Improves physical memory use for applications requiring faster access to large amounts of data
Up to 8MB ECC L2 cache per processor
*Provides increased performance
Up to 64GB ECC Chipkill™ memory
* Allows exploitation of 64-bit addressing for large database applications
*Provides growth options with much greater throughput
*Significantly lowers number of memory failures that cause system outages; thus increasing system availability
Rack-drawer configuration
*Allows for efficient utilization of floor space
*Provides flexible growth in processor, I/O and storage capacity
Up to 56 hot-plug PCI slots
*Dramatically improve availability and provide uninterrupted growth for new adapters
*Provide increased connectivity for e-business applications
Built-in service processor
*Continuously monitors system operations and takes preventive or corrective action for quick problem resolution and high system availability
*Allows diagnostics and maintenance to be performed remotely
Hot-plug redundant power and cooling subsystems
*Allow uninterrupted operations if a power supply or cooling fan becomes disabled
Dynamic Processor Deallocation
*Automatically deallocates resources when impending processor failures are detected so applications can continue to run uninterrupted
NEBS Level 3 compliant
*Offers rugged packaging required for telecommunications central office operations and other harsh computing environments
SP™ Switch attachment
*Allows attachment to a high-speed SP Switch providing consolidation and operational advantages in a cluster environment
IBM eServer Cluster 1600
*Provides centralized management of multiple systems
*Provides ability to handle unexpected workload peaks by sharing resources
*Allows for more granular growth so user demands can be readily satisfied
