About the PERC-H355
The Dell PERC-H355 is a Dell PERC H355 12Gb/s SAS PCIe Gen4 Entry RAID / HBA Controller designed to manage enterprise RAID storage across SAS, SATA, and NVMe drives. Engineered with dedicated I/O processing silicon and onboard cache, the PERC-H355 executes hardware RAID levels 0, 1, 5, 6, 10, 50, and 60 with battery-backed or flash-backed cache protection. In Dell's server line-up, PERC-H355 ensures data availability and write caching for mission-critical storage volumes.
Compatibility
The PERC-H355 controller installs into dedicated storage slots or PCIe risers on Dell PowerEdge servers including R750, R650, R760, R660. The PERC-H355 interfaces with internal hot-plug drive backplanes via SAS or SlimSAS cabling and manages drives mounted in appropriate chassis caddies. Supported operating systems on the PERC-H355 include VMware ESXi, Windows Server, and Linux distributions with Dell PERC driver support.
How to identify a genuine unit
Authentic Dell PERC-H355 PERC controllers display a serialized label showing DP/N 405-AAYS, PERC branding, and Broadcom or LSI manufacturing markings. Within iDRAC under Storage Controllers, the PERC-H355 card enumerates with full firmware revision, battery or supercapacitor health telemetry, and connected virtual disk details.
Buying used
When sourcing a pre-owned PERC-H355, inspect the card PCB for damaged surface passives or warped heatsink assemblies. Test the backup battery or supercapacitor pack on the PERC-H355 to ensure it holds a charge and reports healthy cache protection in iDRAC. Verify that all PERC-H355 SAS/NVMe physical channels detect attached drives without bus timeout errors.
