The Dell PERC 9 H830 12Gb SAS RAID Controller LP delivers powerful RAID management capabilities, ideal for high-demand Dell systems. Supporting both 12Gb/s SAS and 6Gb/s SATA interfaces, and built on a PCIe Gen 3.0 platform, it provides exceptional data transfer rates and system performance for storage-intensive applications.
Equipped with 2 GB NV cache and a flash-backed write cache, the H830 ensures data integrity and fast recovery. With dual 2x4 external SAS ports, support for RAID levels 0, 1, 5, 6, 10, 50, and 60, and the ability to manage up to 255 drives, it offers outstanding scalability and flexibility for enterprise storage environments.
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.
