HPE SR932i-p Gen11 RAID controller

The HPE SR932i-p Gen11 is a PCI Express storage controller built for Gen11 servers. It provides 8GB of cache memory and supports RAID 0/1/5/6/10/50/60/1T/10T across four 8-lane SlimSAS ports. The card targets administrators who need hardware RAID acceleration for direct-attached storage arrays. It is not suited for systems that lack a compatible PCI Express slot or that require software-only RAID management.

Sustained throughput and cache behaviour

The controller delivers up to 46 GB/s of bi-directional throughput and up to 3.5M IOPs under load. The 8GB wide cache absorbs write bursts and keeps read latency low during extended I/O streams. This architecture helps maintain consistent performance when multiple virtual machines or databases share the same drive group. Workloads that exceed the cache capacity or the lane bandwidth will see reduced gains compared with short bursts.

PCI Express lane and connector limits

The card operates across 32 PCI Express lanes using a 4x8 SlimSAS layout. Each connector carries eight lanes, so the host must provide matching slot width and electrical support. Servers limited to fewer lanes or a different connector type cannot utilise the full transfer rate. The interface does not support additional drive channels beyond the four ports defined by the physical layout.

Questions about this item

How much power does the SR932i-p Gen11 draw when running 24/7?

The controller provides up to 46 GB/s bi-directional throughput and 3.5M IOPs with 8GB cache, operating over a PCI Express x32 lane interface designed for sustained server workloads.

Which cables or drive backplanes are needed to connect drives to the 4x8 SlimSAS ports?

The card uses four 8-lane SlimSAS connectors (4x8) so you need matching SlimSAS cables or a compatible backplane that accepts the same interface.

Will this RAID controller work in a Gen10 server chassis I already own?

The SR932i-p Gen11 is a Gen11 plug-in storage controller with SPDM support and requires a Gen11-era PCI Express slot and firmware stack for full operation.
