Dell-PERC H755 RAID Controller
The Dell PERC H755 is a high-performance enterprise hardware RAID controller designed for Dell PowerEdge servers. It provides 12Gb/s SAS connectivity, NV Cache technology, and support for advanced RAID configurations, delivering reliable storage performance, data protection, and scalability for modern data-center workloads.
Description
The Dell PERC H755 is an enterprise-class PowerEdge RAID Controller (PERC) designed for modern Dell PowerEdge server platforms. It provides hardware-accelerated RAID processing for internal server storage and is designed to support demanding enterprise workloads.
The controller supports 12Gb/s SAS connectivity and compatible SAS and SATA drives, including enterprise hard disk drives and solid-state drives. Its dedicated RAID processing capabilities help manage storage operations efficiently while reducing dependency on the host CPU.
The H755 incorporates NV Cache technology to improve write performance and help protect cached data in the event of a power interruption. This makes it well suited to applications where consistent storage performance and data protection are important.
The controller supports commonly deployed RAID levels including RAID 0, RAID 1, RAID 5, RAID 6, RAID 10, RAID 50, and RAID 60, enabling administrators to configure storage according to their requirements for performance, capacity, and fault tolerance.
Advanced management capabilities include RAID configuration, drive monitoring, rebuild operations, online capacity expansion, and hot-plug drive support when used with compatible PowerEdge backplanes. The controller integrates with Dell server-management tools to simplify storage administration.
