The HPE Smart Array P416ie-m SR Gen10 Controller, supporting 12Gb/s SAS and PCIe 3.0 provides enterprise-class storage performance, reliability, security and efficiency needed to address your evolving data storage needs while supporting advanced RAID levels with 2 GB flash-backed write cache (FBWC). This controller operates in Mixed Mode which combines RAID and HBA operations simultaneously and offers enhanced security by encrypting data-at-rest on any drive with HPE Smart Array SR Secure Encryption. It has eight external SAS lanes, allowing connection to SAS or SATA drives in the HPE Synergy D3940, and eight internal SAS lanes, allowing connection to drives inside the HPE Synergy compute modules. The Gen10 controllers are supported by the HPE Smart Storage Battery, which supports multiple devices and is sold separately.The HPE Smart Array P416ie-m SR Gen10 Controller, supporting 12Gb/s SAS and PCIe 3.0 provides enterprise-class storage performance, reliability, security and efficiency needed to address your evolving data storage needs while supporting advanced RAID levels with 2 GB flash-backed write cache (FBWC).
