What kind of mainframe technology goes into the new eServer pSeries 690?
We have put in things like Chip Kill technology, partitioning and self-healing. Chip Kill technology says that even if a memory chip dies/fails I can reconstruct all the information inside that failed chip. This increases the reliability of the system’s memory. Partitioning technology allows you to virtualize servers. Our p690 system allows you to build up to 16 logical partitions, but it’s not just the number it’s how you build those partitions. The resources in these partitions are uncoupled and each partition can be configured to have a specific number of resources. The granularity of these partitions is one processor, one PCI adapter and a minimum of 1 GB memory, in increments of 256 MB. Our competition (Sun) offers 18 domains with 72 processors, but those are physical partitions. Partitioning was first introduced on the IBM mainframes in the late 1980s. What are the migration issues involved when companies move from a room full of servers to a single server with multiple processor
