1.2 Model summary
This section summarizes the models that are available for each of the eX5 systems.
1.2.1 IBM System x3850 X5 models
Table 1-1 lists the standard x3850 X5 models.
Table 1-1 Base models of the x3850 X5: Four socket-scalable server
1.2.2 Workload-optimized x3950 X5 models
Table 1-2 on page 4 lists the workload-optimized models of the x3950 X5 that have been
announced. The MAX5 is optional on these models. (In the table,
std is standard, and max is
maximum.)
Model 5Dx
Model 5Dx is designed for database applications and uses solid-state drives (SSDs) for the
best I/O performance. Backplane connections for eight 1.8-inch SSDs are standard and there
is space for an additional eight SSDs. The SSDs themselves must be ordered separately.
Because no SAS controllers are standard, you can select from the available cards as
described in 3.9, “Storage” on page 90.
Model 4Dx
Model 4Dx is designed for virtualization and is fully populated with 4 GB memory dual inline
memory modules (DIMMs), including in an attached MAX5 memory expansion unit, a total of
384 GB of memory. Backplane connections for four 2.5-inch serial-attached SCSI (SAS) hard
disk drives (HDDs) are standard; however, the SAS HDDs themselves must be ordered
separately. A ServeRAID BR10i SAS controller is standard in this model.
