Smart Array P430 RAID Controller

The HPE Smart Array P430 is a low-profile PCI Express 3.0 x8 SAS RAID controller with 2 GB flash-backed write cache. It provides enterprise-class data protection and storage performance for select ProLiant Gen8 rack and tower servers through eight internal SAS ports.

Suited for Gen8 server upgrades

This controller suits administrators expanding direct-attach SAS storage on supported Gen8 platforms who need hardware RAID with flash-backed cache. It is not for systems lacking a PCIe 3.0 x8 slot or for environments that require external SAS connectivity.

PCIe 3.0 x8 host interface

The card installs in a PCI Express 3.0 x8 slot and presents eight internal 6 Gb/s SAS ports. Compatibility depends on the server having this exact slot type and supported firmware; verify the host platform before purchase.

Questions about this item

How do I install the 698529-B21 Smart Array P430 into a Gen8 server and which step is often missed?

Seat the low-profile card into a PCI Express 3.0 x8 slot, connect the eight internal SAS ports to the backplane, then enable the controller in the system ROM before creating any logical drives — skipping the ROM enable step leaves the drives invisible to the OS.

What maintenance does the 2 GB flash-backed write cache require over time?

The FBWC module uses NAND flash and a super-capacitor; no battery replacement is needed, but the super-capacitor should be checked after several years of continuous operation to ensure it still holds enough charge for a clean cache flush during power loss.

What limit appears first when the P430 sustains heavy random-write workloads?

The 6 Gb/s SAS link and the 2 GB flash-backed cache bandwidth become the bottleneck before the PCIe 3.0 x8 host interface saturates, capping sustained write throughput under intense I/O.
