The initial customer technical support was efficient and effective.
The performance monitoring feature is useful as it can report in 15 minute intervals by hour, day, week, month, or by a custom date range.
The FlashSystem 900 consistently delivers performance below 1ms for read/write. This performance is essential for an effective SVC stretch-cluster configuration across two datacenters, and presenting active-active storage to the customer.

An easy interface to set up, good build quality, and easily accessible parts for hot swapping combined with sub 500 us latency under heavy load.
