64 IBM eX5 Implementation Guide3.3 ModelsThis section lists the currently available models. The x3850 X5 and x3950 X5 (both modelsare machine type 7145) have a three-year warranty.For information about the recent models, consult tools, such as the Configurations andOptions Guide (COG) or Standalone Solutions Configuration Tool (SSCT). These tools areavailable at the Configuration tools website:http://www.ibm.com/systems/x/hardware/configtools.htmlx3850 X5 base models without MAX5Table 3-2 lists the base models of the x3850 X5 that do not include the MAX5 memoryexpansion unit as a standard. The MAX5 is optional. In the table, std is standard, max ismaximum, and C is core (such as 4C is 4-core).Table 3-2 Base models of the x3850 X5: Four-socket scalable serverWorkload-optimized x3950 X5 modelsTable 3-3 on page 65 lists the workload-optimized models of the x3950 X5 that have beenannounced. The MAX5 is optional on these models. (In the table, std is standard, and max ismaximum.)Model 5DxModel 5Dx is designed for database applications and uses SSDs for the best I/Operformance. Backplane connections for eight 1.8-inch SSDs are standard and there is spacefor an additional eight SSDs. You must order the SSDs separately. Because no SAScontrollers are standard, you can select from the available cards that are described in 3.9,“Storage” on page 90.Model 4DxModel 4Dx is designed for virtualization and is fully populated with 4 GB memory DIMMs,including in an attached MAX5 memory expansion unit, for a total of 384 GB of memory.Model aa.
