The Storwize® V7000 2076-724/U7Bnode canisters include hardware changes that significantly differ from
earlier model node canisters. The differences help distinguish the types of node canisters. The main
difference is that Storwize V7000 2076-724/U7B node canisters are not side by side in the control enclosure,
but each is the full width (minus the width of both power supplies) and half the height of the
control enclosure, sitting one above the other in an inverted orientation.
Figure 1 shows the canister release
levers extended to either remove or replace the bottom of the two node canisters in a Storwize V7000 2076-724/U7B control enclosure. The inverted
(upside down) upper node canister is also shown in the illustration.Figure 1. Rear of the Storwize V7000 2076-724/U7B
enclosure
Other differences between Storwize V7000 2076-724/U7B control enclosures and earlier control enclosures are numerous:
New Intel CPU platform: dual Intel Skylake 8 core 1.7GHz processors with 32
Hyperthreads per node canister
Removable Trusted Platform Module (TPM)
From 4 to 24 DDR4 (288p socket) DIMMs in 24 DIMM slots in
each node canister, supported as base memory and cumulative, sequential upgrades:
64 GB per node canister as 4 x 16 GB DIMMs (default base installation)
128 GB per node canister as 8 x 16 GB DIMMs (the first upgrade of 64 GB raises the cumulative
total to 128 GB total memory per canister)
192 GB per node canister as 12 x 16 GB DIMMs (the second upgrade of 64 GB raises the cumulative
total to 192 GB total memory per canister)
576 GB per node canister as 12 x 16 GB DIMMs and 12 x 32 GB DIMMs (the third upgrade of 384 GB
raises the cumulative total to 576 GB total memory per canister)
Note: The control enclosure has two
canisters. To reach the system total cache of 1,152 GB, multiply the above figure of 576 GB by
two.
