The Dell PERC 11 H355 Front RAID Controller delivers efficient hardware RAID functionality for enterprise environments requiring front-accessible storage management. With 12Gb/s SAS and 6Gb/s SAS/SATA drive support, it connects through a 16-port 2x8 internal configuration and interfaces via PCI-e 4.0.
Supporting RAID levels 0, 1, and 10, the H355 Front Controller manages up to 32 drives in either RAID or non-RAID configurations. Built without onboard cache, it offers a reliable, streamlined solution for servers needing flexible, high-speed, and dependable storage control from the front bay architecture.
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.
