CAUTION!
–
When using the TPM, note the program descriptions provided by the
third party manufacturers.
–
You must also create a backup of the TPM content. To do this, follow
the third party manufacturer's instructions. Without this backup, if the
TPM or the baseboard is faulty you will not be able to access your
data.
–
If a failure occurs, please inform your service about the TPM
activation before it takes any action, and be prepared to provide them
with your backup copies of the TPM content.
3.2
Main memory
The baseboard can be equipped with 4 to 8 CPU Memory Risers
(CPUMEMRs). Each CPUMEMR includes one processor and can be equipped
with up to 16 DIMM memory modules.The DIMM slots are suitable for 2 GB,
4 GB, 8 GB, and 16 GB DDR3 DIMM modules with 1333 MHz. Thus, the system
supports a maximum memory configuration of 2 TB with availability of 16 GB
DIMM modules.
ECC with memory scrubbing and the single-device data correction (SDDC)
function are standard. There is no support for non-ECC-DIMMs.
Basically, the memory modules of an individual CPUMEMR are assigned to the
processor installed on this CPUMEMR. However, every CPU can access the
memory modules installed on all other CPUMEMRs via the corresponding
CPUs, see
figure 3
.
The basic configuration includes four CPUMEMRs. This configuration can be
expanded in two steps. Each steps includes two additional CPUMEMRs. In the
4 and 6 CPUMEMR configurations, an air duct is installed in an empty slot.
