16-port SAS RAID controller

The HP Smart Array P800 provides sixteen SAS ports on a PCI Express card with 512 MB of integrated cache. It fits a standard bracket and is designed for servers that need many direct-attached drives. The controller manages RAID levels across a high port count without additional expander hardware. It suits administrators expanding internal storage arrays in compatible HP ProLiant systems.

Sustained throughput with 512 MB cache

The onboard cache absorbs write bursts and reorders reads to keep disk queues short during long backup or database jobs. Battery-backed options preserve cached data if power fails, preventing array corruption during extended writes. Thermal throttling is managed by the server chassis airflow rather than an on-card fan. The card targets workloads that run for hours, not brief benchmarks.
