The Dell fPERC 10 H345 12Gb SAS RAID Controller provides reliable hardware RAID support for external storage environments. Built with PCI-e 3.0 architecture, it supports SAS and SATA drives across multiple speeds and connects through a 2x8 external SAS interface for fast, scalable storage deployments.
Designed for efficiency without onboard cache, the H345 supports RAID levels 0, 1, and 10. Capable of managing up to 63 drives, it offers a dependable and streamlined solution for enterprise applications that demand flexible and robust external RAID configurations.
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.
