8408-E8D: IBM Power 750 Express Server

The 8408-E8D is the IBM Power 750 Express, a 5U 19-inch rack-mount POWER7+ server. It takes one to four 8-core dual chip modules, each built from two 4-core chips, so a system has 8, 16, 24 or 32 cores and all cores are active. The modules run at 3.5 GHz (feature EPT8) or 4.0 GHz (EPT7), every module in a system must be the same feature, and each module has 10 MB of L3 cache per core and 256 KB of L2 per core.

The board has 64 DDR3 DIMM slots, 16 per module, filled in feature pairs of 8, 16 or 32 GB at 1066 MHz up to 1,024 GB. The optional Active Memory Expansion hardware accelerator (feature 4792) can expand AIX partition memory by up to 125 percent. Six hot-swap 2.5-inch SAS or SSD bays make up the internal storage, up to 5.4 TB of HDD or 3.6 TB of SSD, and they can be split into two sets of three bays across the two integrated SAS adapters. A slim SATA DVD-RAM bay is required.

There are six PCIe Gen2 x8 slots plus two GX++ slots, and up to four 12X-attached PCIe drawers (#5802 or #5877) add as many as 40 PCIe Gen1 slots. The EXP30 Ultra SSD I/O Drawer can be added with 6-pack SSD features rated at up to 140,000 IOPS, and the 4-pack features at up to 90,000 IOPS. Redundant 1,925 W hot-swap power supplies are standard, and the Integrated Multifunction Card choices cover dual 10 Gb copper or optical ports with Gb Ethernet.

One unit is 447 mm wide, 858 mm deep and 217 mm high, and weighs 70.3 kg. The 9109-RMD Power 760 shares the same chassis dimensions. Other IBM Power7 servers are the 8233-E8B and the 9179-MHB Power 780, and the IBM Power7 server parts hub has more.
