The pSeries 680 is part of the IBM eServer product line—advanced servers that can help lower costs, improve efficiency and speed e-business transformation. With 4 to 24 microprocessors, each with 16MB of ECC (error checking and correcting) Level 2 (L2) cache, the pSeries 680 has the power, capacity and reliability for the most demanding e-business applications. For customers with lower perfomance needs, 6 to 24 450MHz processor options are available.

The pSeries 680 is the first UNIX platform to feature RS64 IV microprocessors, based on state-of-the-art copper, silicon-on-insulator (SOI) technology from IBM. It delivers lots of power for business applications with a total aggregate internal bandwidth of 43.2GB/sec for enhanced throughput.

The pSeries 680 (p680) provides the scalability necessary to handle business growth smoothly, and extend business-critical applications to the Web. Processors, cache and memory are packaged in "books" with four or six processors1 to protect the sensitive electronics. As demands on the system grow, up to three additional processor books—each with six processors—can simply be added and plugged into the system as required. The combination of the p680 system and AIX® operating system helps companies to easily handle unexpected peaks in demand. The Workload Manager function of AIX automatically allocates system resources based on customer-established priorities. This allows critical applications to remain responsive, even if multiple applications are running on a single pSeries 680.

The Capacity Upgrade on Demand feature enables businesses to scale the system very quickly to handle requirements for more computing resources. For a fee, one or more additional processor books may be installed, but initially disabled. When the need for additional capacity arises, an AIX command activates as many additional processors as required in increments of two. Workload Manager ensures that system resources are allocated to accommodate the newly activated processors. Capacity planning is easier to implement with granular growth options (i.e. 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, 24 processors).
