These are verified P816i-a family specifications. Confirm that the physical item offered under 804341-001 matches this controller model and check which accessories are supplied.
The P816i-a provides four internal x4 Mini-SAS ports, offering a total of 16 SAS lanes.
This allows the controller to connect to up to 16 compatible SAS or SATA drives without requiring a separate SAS expander in supported direct-connect configurations.
For businesses using multiple internal drives, this arrangement can simplify storage connectivity while supporting demanding server applications.
The controller supports SAS transfer rates of up to 12Gb/s per lane. Actual storage performance depends on the installed drives, backplane, cabling and server configuration.
Unlike entry-level cacheless controllers, the P816i-a includes 4GB flash-backed write cache.
This cache helps manage supported storage operations and can improve performance for suitable workloads.
The controller requires compatible cache backup power hardware for protected write-cache operation. HPE supports its Smart Storage Battery and selected Hybrid Capacitor options, which are supplied separately.
Before replacing an existing controller, check whether the required battery or capacitor is already installed and functioning correctly.
The P816i-a supports several RAID levels, including RAID 0, 1, 5, 6, 10, 50 and 60, along with Advanced Data Mirroring options.
These configurations offer different combinations of storage capacity, performance and fault tolerance.
The controller also supports Mixed Mode, allowing RAID and HBA operations to run simultaneously.
This may be useful when a server needs both managed RAID volumes and individual drives presented to the operating system.
RAID does not replace regular data backups. Businesses should maintain independent backups before changing controller hardware or storage configurations.
HPE lists the Smart Array P816i-a SR Gen10 controller as an option for selected ProLiant servers, including:
Compatibility depends on the server model, storage backplane, controller slot, cabling and firmware.
The P816i-a is a Type-a modular controller. It does not use a conventional PCIe expansion slot, even though its host interface is PCIe 3.0 x8.
HPE also offers a low-height P816i-a variant for certain server configurations. Check the required controller form factor before purchasing.
If an existing Smart Array controller has failed, confirm the hardware identification before fitting a replacement.
Check the following:
Follow HPE’s maintenance instructions when replacing the controller. Avoid initialising existing arrays until the correct recovery procedure has been confirmed.
A New or unused P816i-a controller may suit businesses maintaining existing Gen10 servers. Confirm whether the item is unused legacy stock and whether the required cables and cache backup components are included.
A Refurbished controller can provide a cost-conscious replacement for an existing server installation.
Before purchasing, ask whether the controller has been tested for hardware detection, SAS connectivity, cache functionality and storage management operation.
For both conditions, confirm the supplied part number, warranty and UK delivery arrangements.
