The 8234-EMA is the IBM Power 560 Express, a POWER6 rack server that IBM released on 7 October 2008. IBM withdrew it from marketing on 7 January 2011 and ended support on 31 March 2019, naming the 8233-E8B as the recommended replacement.
It is sold as a 4-core, 8-core or 16-core system, the 16-core version being two system units cabled together in a rack. Each unit has six PCI slots plus two GX+ slots: three PCIe x8 slots and two PCI-X DDR slots (64-bit, 266 MHz) take long cards, and one short PCIe x8 slot completes the six. The sixth slot shares its connector with the first GX+ slot, so it takes either a PCIe x8 adapter or a GX+ adapter. The second GX+ slot is not active on a 4-core system. All slots support Enhanced Error Handling.
Adapters go in generation 3 blind-swap cassettes, which IBM notes rules out internal SCSI connectors on PCI storage adapters. Capacity is expanded through the GX+ slots: a 4-core unit supports one GX slot, with six I/O units on RIO-2 or four on a 12x Channel Adapter, and an 8-core unit has two. The 5796 PCI-X drawer and the RIO-2 attached 7311-D20 are supported, and the PCIe drawers feature 5802 and 5877 attach through the 12x adapters, up to two drawers each.
The recommended replacement is listed as the 8233-E8B. More IBM server parts are on the Power7 server parts page.
