HPE Smart Array P441 SAS Controller

The HPE Smart Array P441 Controller is a low- profile, PCIe3 x8, 12Gb/s Serial Attached SCSI (SAS) RAID controller that provides enterprise-class storage performance, increased external scalability, and data protection for select HPE ProLiant Gen9 rack and tower servers, and Apollo systems. It features eight external physical links and delivers increased server uptime by providing advanced storage functionality, including online RAID level migration (between any RAID levels) with flash back write cache (FBWC), global online spare, and pre-failure warning. This controller includes transportable FBWC allowing the data in the cache to be migrated to a new controller. The Gen9 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 simple upgrade process.
