Frequently Asked Questions

What happens to cached data if power is lost?

The flash-backed write cache preserves in-flight data during a power interruption and writes it to the drives once power returns.

Can this controller mix SAS and SATA drives?

Yes, it supports both SATA 6Gb/s and SAS 12Gb/s drives through its single port.

When drive failure isn”t an option, the Smart Array P440 gives server administrators the RAID flexibility and cache protection needed to keep critical data available and performing well under load.
