Rack configurations
IBM FlashSystem A9000R supports racks that contain a total of two to six grid
elements.
For various configuration feature codes see:
v “Flash enclosure components and feature codes” on page 13
v “Grid controller components and feature codes” on page 14
v
“Main power cables specifications” on page 29
Note: An IBM FlashSystem A9000R with less grid controllers also has fewer usable
Fibre Channel and iSCSI ports, as well as less processing power.
For more information regarding capacity, processors, memory, and connectivity, see
Chapter 2, “System specifications,” on page 5.
Fully populated rack
A fully populated rack contains 12 grid controllers and 6 flash enclosures.
Note: A valid configuration always has two times the amount of grid controllers
than flash enclosures.
Each grid controller contains 384 GB RAM capacity, for a total of 4608 GB RAM for
a fully populated rack.
Each flash enclosure supports RAID 5 (10+1 MicroLatency modules with
distributed parity, in accordance to RAID 5) with one spare MicroLatency module
(total 12 MicroLatency modules). The physical capacity is equal to 10 MicroLatency
modules with 2.9 TB
or
5.7 TB, giving a total of either 29 TB
or
57 TB per flash
enclosure and 174 TB
or
342 TB for a fully populated rack.
Figure 3 on page 12 shows an example the front and back of a fully populated IBM
FlashSystem A9000R.
