Dell PERC H330 RAID Controller Adapter

Dell PERC H330 Controller — Entry Hardware RAID for PowerEdge Servers

The Dell PERC H330 controller is Dell’s entry-level hardware RAID adapter for PowerEdge rack and tower servers. RAID processing runs entirely on the controller chip rather than consuming host CPU cycles. This reduces processor overhead during RAID rebuild events and delivers more predictable I/O latency under mixed workloads compared to software RAID implementations.

The Dell PERC H330 controller supports RAID levels 0, 1, 5, 6, 10, 50 and 60 across up to 32 physical drives. RAID 5 on data volumes with RAID 1 on boot drives is the standard configuration for most South African server deployments at this tier. RAID 6 tolerates two simultaneous drive failures. This is appropriate for larger arrays where the risk of a second failure during a rebuild is statistically significant.

SAS and SATA Drive Connectivity

The Dell PERC H330 controller supports both SAS 12Gbps and SATA 6Gbps drives in mixed configurations. Enterprise SAS hard drives offer dual-port design. They also carry higher mean-time-between-failure ratings than equivalent SATA drives. The H330 ships in a low-profile PCIe 3.0 x8 form factor, fitting 1U and 2U PowerEdge rack servers with low-profile riser slots. A compatible riser card is required in servers that do not include one as standard.

When to Choose H330 Over Embedded SATA

PowerEdge embedded SATA controllers such as the S140 and S150 perform software RAID using host CPU cycles. The Dell PERC H330 controller offloads this processing to dedicated hardware. It also adds SAS drive support, which the embedded controller does not provide. For storage-intensive workloads with frequent rebuild activity, the H330 delivers clear advantages over embedded alternatives. Mixed SAS and SATA configurations also benefit from its wider drive support.
