VMA-series Memory Array Installation and Service Guide

Memory arrays store up to 64, 128, 256, or 512 GB of data per memory

module providing up to 43 TB of raw flash storage per system. The amount of

usable memory in a system is the number of VIMMs used for data storage,

which is four per redundant array of independent disks (RAID) group (up to 64

VIMMs), multiplied by the amount of memory per module, multiplied by the

usable percentage the system is formatted for. For example, in a fully loaded

system with 84 VIMMs, the usable memory is 64 VIMMs multiplied by 128 GB,

multiplied by the usable percentage, such as 87.5%, which is 7.2 TB.

VIMM Configurations

The Memory Array holds up to 84 VIMMs, which operate in the VIMM

configurations listed in the following table.

VIMM Slot Locations

The Memory Array is available in several VIMM configurations. Table 2.3 lists the

VIMM slot numbers used for each configuration. Use the information in the table

when adding, removing, or replacing a non-working VIMM to ensure that the

VIMMs are still in their correct positions. See Replacing VIMMs on page 113 for

information on replacing an errored VIMM.
