The 8203-E4A is the machine type and model of the IBM Power 520 Express built on POWER6 and POWER6+ processors. IBM's Power 520 Redpaper describes it as the unified configuration, orderable from October 2008, that can run AIX, IBM i or Linux in one or several partitions. IBM i on this model needs system firmware level EL340_039 or later.
It comes as a 4U rack-mount drawer (feature #7200) or as a deskside tower. The drawer measures 173 x 440 x 538 mm (height, width, depth) and weighs 34.0 kg; the deskside version is 540 x 182.3 x 628 mm at 40.8 kg.
Processor options are 1, 2 or 4 cores, all permanently activated. The 4.2 GHz POWER6 card comes in 1-, 2- and 4-core form, and the 4.7 GHz POWER6+ card in 2- and 4-core form. The processors are soldered to the planar, so the processors cannot be swapped, and each core has 4 MB of level 2 cache.
Memory runs from 1 GB to 64 GB, capped by core count: 16 GB on a 1-core system, 32 GB on 2 cores and 64 GB on 4 cores. The 1- and 2-core systems have four DIMM slots and the 4-core system has eight, and the 64 GB feature (#4288) needs the 4-core model. / Internal storage is up to six SAS drives on one of three backplanes: six 3.5 inch bays (default, no external SAS port), six 3.5 inch bays with an external SAS port, or eight 2.5 inch bays with an external SAS port. Expansion is five hot-swap PCI slots (three PCIe x8, two PCI-X DDR) plus GX+ adapter slots for RIO-2 or 12X loops; a 1-core system supports neither loop type.
Built-in ports are an Integrated Virtual Ethernet card (2 or 4 gigabit ports, or 2 ten-gigabit), three USB, two serial and two HMC ports. A 950 W hot-swap power supply is standard, with redundancy optional.
Compare with its bigger sibling on the page for the Power 550 Express server and the Power 595 server, or browse the IBM server systems category.
