Memory in ztC Endurance Systems
Read this topic before you add or replace registered dual in-line memory modules (RDIMMs
Registered dual in-line memory module. RDIMMs have a register between the system’s memory controller and the dynamic random-access memory modules, thus allowing for greater capacity and increased reliability.) in a ztC Endurance system.
Memory Components in Each Compute Module
Table 1 lists the memory components in each compute module A customer-replaceable unit (CRU) located at the front of the ztC Endurance system. It is equipped with processors, RDIMMs, BIOS, BMC, fans, and other technology to boot and run the ztC Endurance system. Each system contains two compute modules..
| Model | Processors | Sockets | RDIMM Slots | Minimum Number of RDIMMs | Maximum Number of RDIMMs |
|---|---|---|---|---|---|
| 31x0 | 1 | 2 | 161 | 1 | 4 |
| 51x0 | 2 | 2 | 16 | 2 | 8 |

Figure 6 shows the area of a compute module that contains memory components. Specifically, the figure shows the two processors, each installed in a socket, and the location of each RDIMM Registered dual in-line memory module. RDIMMs have a register between the system’s memory controller and the dynamic random-access memory modules, thus allowing for greater capacity and increased reliability. slot.
