Dimms - EMC VNX Series Parts Location Manual

DIMMs

SP DIMMs
The Storage Processor (SP) requires either 24 GB (optionally 48 GB) per SP or 48
(optionally) 96 GB per SPE or array and the Data Mover requires 24 GB per Data Mover.
Figure 32 on page 40 shows an example of the SP DIMM slot location.
The base SP CPU uses SDRAM DIMMs
Double-Data-Rate 3 (DDR3) type memory for a total of 24 GB per SP CPU or 48 per SPE.
Figure 32 on page 40 shows an example of the SP DIMM slot location.
To allow for a larger cache when full data services are enabled, an SP CPU using optional
six 8-GB SDRAM DIMMs for a total of 48 GB per SP or 96 GB per SPE is used.
page 40 shows an example of the SP DIMM slot location.
Figure 33 on page 40 shows an example of the SP DIMM with a part number label.
Table 27 on page 41 lists the part number, description, and whether it is a FRU or CRU.
IMPORTANT
The DIMM part numbers are visible only when you remove the DIMM from the DIMM slot.
You must first take the SP out of service, disconnect any SP cables, remove the SP from the
SPE, then remove the SP power supply/cooling module from the SP (see
page 13 and Figure 10 on page
DIMM cover up in the SP CPU, and then remove the DIMM from the DIMM slot. Ensure that
you remove only those DIMMs that you intend to replace. For more information about
removing and installing the DIMM or memory module, refer to the
module
procedure available from the VNX Procedure Generator program.
Note the orientation of the VNX7500 Block and File (Unified) platform SP DIMMs (see
locations DIMM 0, DIMM 1, DIMM 2, DIMM 3, DIMM 4, and DIMM 5 in
on the DIMM cover also identifies the DIMM slots as DIMM 0, DIMM 1, DIMM 2, DIMM 3,
DIMM 4, and DIMM 5.
1. The term DIMM is used throughout this guide. The term DIMM is also referred to as a memory
module. These terms are interchangeable and basically mean the same thing.
