Adapter Specs Type: RAID Controller Drive Types: 6Gb/s SAS / SATA Interface: PCI Express 2.0 Ports: 2 x Mini-SAS (Internal) Cache Memory: N/A Write Back Cache: N/A RAID Levels: 0, 1, 5, 10, 50 Max Drive Support: 16 RAID / 32 Non-RAID RAID Support: Hardware Mini SAS Cable: F4DPW Part Number: 3P0R3 The Dell PERC H310 RAID Controller (3P0R3) is a full-height, hardware RAID card designed for SAS/SATA environments, supporting up to 16 RAID or 32 non-RAID drives. With dual internal Mini-SAS ports and PCIe 2.0 interface, it ensures fast, reliable storage connectivity for enterprise workloads. Supporting RAID 0, 1, 5, 10, and 50, this controller is ideal for balancing performance with redundancy. Though it lacks cache and write-back capabilities, it offers stable hardware RAID for small to mid-size data environments. Compatible Mini-SAS cable: F4DPW. Summary of RAID levels Summary of RAID levels Following is a list of the RAID levels supported by the PERC 12 series of cards: RAID 0: Uses disk striping to provide high data throughput, especially for large files in an environment that requires no data redundancy. RAID 1: Uses disk mirroring so that data written to one physical disk is simultaneously written to another physical disk. RAID 1 is good for small databases or other applications that require small capacity and complete data redundancy. RAID 5: Uses disk striping and parity data across all physical disks (distributed parity) to provide high data throughput and data redundancy, especially for small random access. RAID 6: Is an extension of RAID 5 and uses an additional parity block. RAID 6 uses block-level striping with two parity blocks distributed across all member disks. RAID 6 provides protection against double disk failures, and failures while a single disk is rebuilding. If you are using only one array, deploying RAID 6 is more effective than deploying a hot spare disk. RAID 10: Is a combination of RAID 0 and RAID 1, uses disk striping across mirrored disks. It provides high data throughput and complete data redundancy. RAID 50: Is a combination of RAID 0 and RAID 5 where a RAID 0 array is striped across RAID 5 elements. RAID 50 requires at least six disks. RAID 60: Is a combination of RAID 0 and RAID 6 where a RAID 0 array is striped across RAID 6 elements. RAID 60 requires at least eight disks.
