The HPE Smart Array P246br Controller is a Flexible Smart Array, 12Gb/s SAS RAID controller that provides enterprise-class storage performance and data protection for the HPE ProLiant BL460c Gen9 Server Blade when adding D2220sb in adjacent slot.

It features four internal physical links and delivers increased server uptime by providing advanced storage functionality with flash-backed write cache (FBWC). The Smart Array P246br Controller delivers increased server uptime by providing advanced storage functionality; including 1GB flash back write cache, pre-failure warning, and optional Secure Encryption. Data compatibility between HPE Smart Array Controllers means customers can easily upgrade to future Smart Array Controllers.

The Gen9 Server family of controllers supports the HPE Smart Storage Battery. With HPE Smart Storage Battery, multiple Smart Array controllers are supported without needing additional backup power sources for each controller, resulting in a simple upgrade process and at a reduced cost.
