The HPE Smart Array P816i-a SR Gen10 Controller, supporting 12Gb/s SAS and PCIe 3.0, is ideal for maximizing performance while supporting advanced RAID levels with 4 GB flash-backed write cache (FBWC). This controller operates in Mixed Mode which combines RAID and HBA operations simultaneously. It has 16 internal SAS lanes, allowing connection of up to 16 SAS or SATA drives without need for the SAS Expander Card providing point to point connectivity to SSDs for lower latency. It also offers encryption for data-at-rest on any drive with HPE Smart Array SR Secure Encryption and accelerates access to data on HDDs with the HPE Smart Array SR SmartCache license which comes standard with this controller. This type-a modular controller occupies a dedicated storage slot without occupying a PCIe expansion slot and provides enterprise-class storage performance, reliability, security and efficiency needed to address your evolving data storage needs. The Gen10 controllers are supported by the HPE Smart Storage Battery, which supports multiple devices and is sold separately.The HPE Smart Array P816i-a SR Gen10 Controller, supporting 12Gb/s SAS and PCIe 3.0, is ideal for maximizing performance while supporting advanced RAID levels with 4 GB flash-backed write cache (FBWC).
