HP NetRAID 4M RAID controller 128MB D9161A

The HP NetRAID 4M is a 4-channel Ultra3 SCSI RAID controller with 128 MB cache on a PCI bus. It provides hardware RAID for servers that use SCSI storage and need a dedicated controller.

128 MB cache capacity

The 128 MB cache handles moderate RAID workloads and typical server I/O. It runs out on very large arrays or sustained heavy write loads that exceed the cache size and PCI bus bandwidth.

Questions about this item

Will the D9161A HP NetRAID 4M work with my existing Ultra3 SCSI drives?

The controller provides four Ultra3 SCSI channels, so your current Ultra3 drives connect directly without adapters.

How can I verify the 128MB cache is active after installing the D9161A?

The BIOS configuration utility and operating-system management tools both report the cache size, confirming the 128MB is recognised.
