IBM iSeries is the midrange server line that runs OS/400 and, on the eServer i5 models, i5/OS. IBM’s handbook for the line covers three groups of systems. The iSeries 270, 820, 830 and 840 use processors named Pulsar, SStar and IStar. The iSeries 800, 810, 825, 870 and 890 come next: the 800 and 810 use SStar processors at 540 and 750 MHz, while the 825, 870 and 890 use POWER4, with the 870 and 890 at 1.3 GHz. The eServer i5 520, 550, 570 and 595 use POWER5 processors.
Machine type 9406 covers the 250, 270, 800, 810, 820, 825, 830, 840, 870 and 890 and the i5 520, 550, 570 and 595, and the i5 520 also has a 9405 form. The i5 520 takes one or two POWER5 processors at 1.5 GHz or 1.65 GHz, with main storage up to 32 GB and up to 20 logical partitions. The i5 550 takes one to four POWER5 processors at 1.65 GHz, with main storage of 2 to 64 GB and up to 40 logical partitions. The 800 and 810 hold 512 to 16384 MB of main storage, the 870 holds 8 to 128 GB and the 890 holds up to 256 GB.
Adapter options for these systems include four IBM-numbered cards. The #2766 PCI Fibre Channel Disk Controller attaches external disk at 1 Gbps or 2 Gbps and needs its own I/O processor. The #2787 PCI-X Fibre Channel Disk Controller has an LC connector and supports a 64-bit, 133 MHz PCI-X bus. The #5704 PCI-X Fibre Channel Tape Controller uses the same LC connector for external tape. The #2757 PCI-X Ultra RAID Disk Controller has four Ultra SCSI buses and a 757 MB compressed maximum cache, giving RAID-5 protection to internal disk units.
Neighboring IBM lines are on the IBM pSeries and IBM Hardware Management Console pages. For the Power generations that followed, see IBM Power 5 server parts, IBM Power 7 server parts and fully licensed IBM iSeries Power 9 servers. The IBM server system category holds more systems, and everything else sits under servers.
