The Dell PERC 11 H755 MX RAID Controller delivers enterprise-grade storage management optimized for the PowerEdge MX modular platform. Supporting Gen3 and Gen4 NVMe, along with SAS and SATA drives, it provides exceptional speed and flexibility through PCI-e 4.0 and a 16 Port 2x8 internal connection.
Equipped with 8GB of non-volatile flash-backed cache, the H755 MX supports RAID levels 0, 1, 5, 6, 10, 50, and 60. With support for up to 8 drives per controller, it offers scalable and secure storage performance ideal for demanding modular server environments.
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.
