HPE 804338-B21 Smart Array P816i-a SR Gen10 12Gb/s SAS 4GB cache 16-port backup media

SKU CH-YGBZ-6P32C MPN 804338-B21

12Gb/s SAS RAID controller with 4GB flash-backed cache and 16 internal ports for server storage expansion

  • 12Gb/s SAS controller delivers high-throughput storage connectivity
  • 16 internal SAS ports support dense drive configurations
  • 4GB flash-backed cache protects data during power loss
  • PCI Express 3.0 x8 host interface provides ample bandwidth
  • RAID 0, 1, 5, 6, 10, 50, 60 and ADM levels enable flexible data protection

HPE Smart Array P816i-a SR Gen10 controller

This 12Gb/s SAS RAID controller installs in a PCI Express 3.0 x8 slot and provides sixteen internal SAS ports through four connectors. Four gigabytes of flash-backed cache protect write data during power loss. It supports RAID levels 0, 1, 5, 6, 10, 50, 60, ADM and ADM10 for a wide range of redundancy and performance profiles. The card is designed for PC platforms running Linux.

Internal storage arrays for servers and workstations

The controller suits administrators building high-port-count internal arrays with hardware RAID and cache protection. It is not intended for systems that lack a PCI Express 3.0 x8 slot or that require external SAS connectivity. Buyers needing a different port count or a host interface other than PCI Express 3.0 x8 should evaluate other options.

Sixteen internal SAS ports via four connectors

The card delivers exactly sixteen internal SAS ports grouped across four connectors, enabling direct attachment of up to sixteen drives or expanders. This port density determines how many devices can be connected without additional hardware. Verify that the target chassis and backplane can accommodate the connector layout and cable routing before purchase.

Questions about this item

How is the P816i-a SR Gen10 installed in the server, and what step is often missed?

Insert the controller into a PCI Express 3.0 x8 slot, connect the 16 internal SAS ports using the four connectors, and ensure the 4 GB flash-backed cache module is fully seated; the step often missed is verifying the cache module clicks into place before closing the chassis.

What maintenance or replacement will the P816i-a SR Gen10 need later?

The 4 GB flash-backed cache module is the only field-replaceable component; if the super-capacitor that protects cached data degrades, the module must be swapped to keep write-back caching active.

What limit appears first on the P816i-a SR Gen10 under sustained heavy I/O?

The PCI Express 3.0 x8 host link caps total throughput, so sustained 12 Gb/s SAS traffic across all 16 ports will hit the bus bandwidth ceiling before the controller itself saturates.
