IBM BladeCenter HX5 12Express ModelsThe following table lists the region-specific Express models. Express models are preconfigured withadditional components such as processors and memory to make the ordering and installation processsimpler.Models with optional MAX5. These models can optionally attach to the MAX5 memory expansion unit.If the MAX5 is attached you cannot also attach the two-node scalability kit to form a two-nodeconfiguration. The reverse is also true - forming a two-node configuration precludes the use of theMAX5.Models with standard MAX5. These models do not support the two-node scalability kit to form atwo-node system since adding a MAX5 and adding a second node are mutually exclusive.Table 3.

Some models have the MAX5 standard (88Y6128) and somemodels have the two-node scalability kit standard (46M6975).‡ With Xeon E7 processors, the memory speed in the HX5 and the MAX5 are the same.§ All models contain an onboard 2-port Gigabit Ethernet controller. Some models also include an additional 10GbExpansion Card installed in the CFFh expansion slot, as follows:(E1) Emulex 10GbE Virtual Fabric Adapter Advanced(E2) Emulex 10GbE Virtual Fabric Adapter Advanced II
