IBM has announced some new XIV power features while withdrawing others.
The changes are being made to simplify the ordering process while making the power choices more robust and better suited to client requirements.
So what changed?
- Some of the Chicago line cords have been withdrawn (where no longer required by law).
- The 30 amp single phase line cords have all been withdrawn. The requirement for four line cords was messy and required careful planning.
- The design of the delta three phase ATS has changed. The big benefit is to remove a restriction in Japan that limited the XIV to 10 modules. This is a major boost for the Japanese market.
The choices for XIV input power will now be:
- Three phase input power using two line cords that are each rated at 32 amps
- Three phase input power using two line cords that are each rated at 60 amps
- Single phase input power using two line cords that are each rated at 60 amps
In Australia/New Zealand, 60 amp single phase is not practical for most clients, so the best choice for power remains the three phase power option (at 32 amps).
This is pretty well an industry standard for Enterprise class disk.
