Dell PERC H755N Front 8GB NV Cache NVMe RAID Controller (9K2C2)

9K2C2 · Refurbished · 1 year warranty

Quantity (units)

Overview

The PERC H755N Front is Dell's NVMe-only version of the PERC 11 controller, and 9K2C2 is its part number. It mounts at the front of the server and runs NVMe Gen3 and Gen4 drives over a PCIe Gen4 host interface.

Hardware RAID on NVMe is the point of this part. It supports RAID 0, 1, 5, 6, 10, 50 and 60, and the 8GB of non-volatile cache protects writes in flight. That makes it a fit for servers built around fast NVMe flash that still need parity protection managed by a controller rather than the operating system.

This controller is also listed under the equivalent part number T4FH6. If your parts list or service tag shows T4FH6, it refers to the same controller.

The 9K2C2 is offered New or Refurbished. Each comes with a warranty of 1 year or 3 years. Let us know the quantity and the server it is going into.
