Featuring 4 GB of NV cache with flash-backed protection, the H745 supports RAID levels 0, 1, 5, 6, 10, 50, and 60. With capacity for up to 240 drives, it provides flexible, high-reliability RAID management for enterprise storage deployments requiring maximum scalability and data security.
-
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.
