Updating hardware options

The Storwize® V3700 hardware can be updated with options installed during the initial installation or at another time.

Depending on the options you purchased, the Storwize V3700 hardware may need to be updated during the initial installation. The particular hardware update may also require a machine code update to enable the hardware functionality.

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.
