Also available is a virtualization workload-optimized model of these HX5s. This is a
pre-configured, pre-tested model targeted at large-scale consolidation. Table 1-7 shows the
model.
Table 1-7 Workload-optimized models of the HX5
Model 7872-68x is a virtualization-optimized model and includes the following features in
addition to standard HX5 and MAX5 features:
򐂰 Forty DIMM sockets, all containing 4 GB memory DIMMs for a total of 160 GB of available
memory.
򐂰 VMware ESXi 4.1 on a USB memory key is installed internally in the server. See 5.15,
“Integrated virtualization” on page 214 for details.
򐂰 Emulex Virtual Fabric Adapter Expansion Card (CFFh).
