Overview

The PERC H355 Front belongs to the PERC 11 generation used in 15th generation PowerEdge servers. As a Front controller, it mounts behind the drive backplane instead of in a rear PCIe slot.

It supports 12Gb/s SAS and 6Gb/s SATA drives through 16 internal ports, and connects to the system over PCIe 4.0 x8. The H355 has no cache listed, which places it as an entry controller for boot volumes, mirrors and general-purpose storage rather than heavy write workloads.

Dell TKK9K also appears as 0TKK9K, the padded form of the part number.

Buyers order it to replace a failed controller, or to keep spares for a group of 15th generation servers. Fitting the same model makes it simpler to bring existing arrays back online.

New, Refurbished and Used units are available. New and Refurbished carry a choice of 1 year or 3 years of warranty; Used carries 90 days. Send the server model and quantity for pricing.
