Dell PERC 11 H755 H750 H355 H350 Users Guide

Dell PowerEdge RAID Controller 11 series adapters, specifically the H755, H750, H355, and H350 models manufactured by Dell, deliver enterprise storage infrastructure for modern server deployments. These PCIe expansion slot interface cards operate over SAS 3.0 at twelve gigabits per second and support up to eight gigabytes of DDR4 write-back cache paired with either a battery backup unit or non-volatile memory module. Hardware variants span riser adapter cards, front-mounted SAS and NVMe configurations, MX sleds, and Mini Monolithic form factors to match diverse chassis backplanes. The flagship H755 model enables native PCIe Gen4 connectivity alongside comprehensive RAID 0, 1, 5, 6, 10, 50, and 60 support, whereas the H350 and H355 variants restrict operations to RAID 0, 1, and 10 without NVMe compatibility or advanced cache encryption.

IT administrators configure and monitor these Dell PowerEdge RAID Controller 11 adapters through four integrated management pathways: a BIOS-integrated Human Interface Infrastructure utility, the PERC command-line interface, Dell OpenManage Storage Management, and out-of-band monitoring via iDRAC firmware. Operational workflows feature online capacity expansion, RAID level migration, virtual disk relocation between physical adapters, and automated background initialization paired with proactive patrol read health checks. The architecture handles hot-swap drive replacement using dedicated or global spare pools, automatically triggering accelerated rebuilds while maintaining continuous uptime during routine maintenance windows. Non-volatile cache preservation guarantees zero data loss during power interruptions by retaining pending writes until system recovery completes.

Compliance and protection requirements are satisfied through hardware-level encryption capabilities including full Opal and TCG standards for self-encrypting drives, instantaneous secure erasure functions, and cryptographic wiping protocols. Key distribution scales from localized storage to centralized enterprise deployment via Dell OpenManage Secure Enterprise Key Manager across distributed data centers. A verified hardware root of trust authenticates all firmware components before execution to prevent unauthorized code injection. Procurement teams select the Dell PowerEdge RAID Controller 11 lineup, particularly the H755 and H350 models from Dell, to consolidate storage provisioning, accelerate virtual machine and database workloads, and enforce strict governance policies across Windows Server, RHEL, SUSE Linux, and VMware ESXi environments without sacrificing administrative efficiency or throughput.
