HP Smart Array P800 RAID Controller
The HP Smart Array P800 is a 16 port serial attached SCSI RAID controller that connects via a PCI-Express x8 interface. It ships standard with RAID 6 ADG and supports over 100 hard drives. This refurbished unit includes 512MB of cache memory and a standard bracket for server installation.
16 Port SAS Connectivity
The single specification that determines compatibility is the sixteen port SAS design paired with a PCI-Express x8 host interface. Servers must provide an x8 slot and SAS backplane or expander cabling to use all channels. Without that port count and interface match the card cannot attach the intended drive array.
Sustained Cache-Backed Throughput
Under sustained load the 512MB cache absorbs write bursts and enables RAID 6 parity calculations without stalling the SAS lanes. The controller maintains consistent throughput across many drives because the cache reduces seek overhead during rebuilds and heavy random I/O. Performance scales with drive count up to the supported limit.

Questions about this item
What does the 16-port SAS design mean for a real server build?
It lets you connect up to 16 SAS drives directly to the controller, supporting over 100 drives in total when expanders are used.
How does the PCI-Express x8 interface affect throughput?
The x8 lane width caps the host link at PCIe x8 speeds, which limits the maximum aggregate bandwidth available to the 16 SAS ports.
What bracket and slot space does the card need to mount?
It ships with a standard bracket and requires one full-height PCIe x8 or larger slot in the server chassis.
