The Dell PERC 10 H345 12Gb SAS RAID Controller FH offers dependable RAID functionality for external storage environments needing SAS and SATA drive compatibility. Built on PCI-e 3.0 architecture, it connects through a 2×8 external SAS interface to deliver high-speed, reliable data access.

Supporting RAID levels 0, 1, and 10, the H345 manages up to 63 drives without the need for onboard cache. This full-height controller provides a scalable, hardware-based storage solution for enterprise systems that require performance, flexibility, and streamlined RAID management.

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.
