Hardware update options
Hardware
update options for the
Storwize V3700 include the
following:
- Expansion enclosures (includes 2 expansion canisters)
- SAS cables for connecting the control and expansion enclosures
- A sufficient number of drives required to populate an array configuration, plus
any additions to increase the spare ratio. All drives should be installed before reconfiguring
- A choice of different host interface adapters to be installed in the
node canister for connectivity to hosts using Fibre Channel,
Fibre Channel over Ethernet, and iSCSI.
The host interface adapters should be planned
during host system planning. Both node canisters must have matching host interface adapter
updates.
- Cache memory update for improved performance in certain use cases. Both node canisters must have matching
updates.
Most updates can
be done concurrently while the system remains operational if there
are redundant components. Refer to the specific hardware installation
instructions for details.
