The Dell PERC 11 H755 SAS 12Gb RAID Controller FRONT delivers robust, high-performance RAID capabilities for storage environments using SAS, SATA, and NVMe drives. With PCI-e 4.0 support and a 16 Port 2x8 internal configuration, it ensures excellent scalability and fast data throughput for enterprise servers.
Equipped with 8GB of non-volatile cache and flash-backed cache protection, the H755 Adapter supports RAID levels 0, 1, 5, 6, 10, 50, and 60. It efficiently manages up to 50 drives with a SAS expander, making it ideal for complex, performance-driven server deployments requiring secure and scalable storage solutions.
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.
