The HP Smart Array P440ar Controller is a Flexible Smart Array, 12Gb/s SAS RAID controller that provides enterprise-class storage performance, increased internal scalability with SAS Expander Card, and data protection for specific HP ProLiant Gen9 rack and tower servers. It features eight internal physical links and delivers increased server uptime by providing advanced storage functionality, including online RAID level migration between any RAID levels with flash backed write cache (FBWC), global online spare, and pre-failure warning.

The Gen9 family of controllers supports the HP Smart Storage Battery. With HP Smart Storage Battery, multiple Smart Array controllers are supported without needing additional backup power sources for each controller, resulting in simple upgrade process. The HP Smart Array P440ar Controller and the attached storage devices are configured and managed by the easy–to-use HP Smart Storage Administrator software which is included in the intelligent provisioning of the server. Data compatibility between the HP Smart Array Controller family allows simple and easy migration at any time when needs for higher performance, capacity, or availability increase such as converting an existing storage volume to more advanced disk array configuration.
