The Dell fPERC 10 H745 12Gb SAS 4GB RAID Controller delivers enterprise-grade storage management with high-speed 12Gb/s SAS and multiple SATA compatibility. Connecting through dual 2x8 external ports and utilizing PCI-e 3.0, it ensures rapid, reliable data transfer for large-scale storage needs.
Equipped with 4 GB of non-volatile cache and flash-backed protection, the H745 supports a wide range of RAID levels, including 0, 1, 5, 6, 10, 50, and 60. With the ability to manage up to 240 drives, it provides robust scalability and data security for demanding enterprise storage deployments.
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.
