Dell PERC H310 SAS RAID Controller

This Dell PERC H310 SAS RAID controller adds hardware RAID to compatible Dell PowerEdge servers. It connects through a PCI-Express 2.0 x8 slot and supports transfer rates up to 6Gb/s. The card is designed for the PowerEdge R720 platform and suits administrators who need internal storage redundancy.

Thermals noise and power draw

The controller operates inside the server chassis and relies on the system airflow for cooling. Power consumption is modest for a hardware RAID adapter and does not require auxiliary power connectors. Acoustic output is determined by the host server fans rather than the card itself.

Build quality and connectors

The mini mono form factor fits the dedicated PERC slot in the R720 without using a full-height PCIe bracket. Internal SAS connectors link directly to the server backplane for drive attachment. This refurbished unit is intended for Dell PowerEdge R720 systems and is not suited for workstations or non-Dell servers that lack the proprietary slot and cabling.

Questions about this item

How is the PERC H310 K09CJ installed in a PowerEdge R720, and what step is often missed?

Insert the card into a PCI-Express 2.0 x8 slot, then connect the internal SAS cables to the controller's ports; the step often missed is securing the mini mono bracket so the card does not shift during operation.

What maintenance or replacement will the PERC H310 K09CJ need over time?

The onboard battery that backs the RAID cache may degrade after several years; when it fails, the controller disables write-back caching, so plan to replace the battery module to keep performance consistent.

What limit appears first when the PERC H310 K09CJ runs sustained workloads?

The PCI-Express 2.0 x8 interface caps total throughput at the 6Gb/s SAS link speed, so heavy sequential I/O from multiple drives will hit that bandwidth ceiling before the controller itself becomes the bottleneck.
