210 3 Server Blades: Setup and Installation Item 1 2 3 4 5 Description Blade Unit/Module SATA Hard Drives (2 per blade node, 4 total) DIMMs (system memory, 8 per node) CPU Heatsinks (4) Top Cover Memory Support Each node of a AB2x280 F1 blade module supports up to 128GB/32GB of ECC Registered/Unbuffered ECC DDR3-1333 SDRAM in eight DIMM sockets. Memory Installation The mainboard of each blade unit must be populated with DIMMs (Dual In-line Memory Modules) to provide system memory. The DIMMs should all be of the same size and speed and from the same manufacturer due to compatibility issues. Populating Memory Slots The mainboard of a AB2x280 F1 blade module has eight memory slots per node. Both interleaved and non-interleaved memory are supported, so you may populate any number of DIMM slots. Populating slots at the same time with memory modules of the same size and of the same type will result in three-channel, interleaved memory, which is faster than single-channel, non-interleaved memory. See the following table and Figure 3-106 for details.
