The Dell 12Gb SAS HBA (Non-RAID) External Controller LP provides high-speed connectivity for external SAS storage systems requiring pass-through architecture without RAID management. Built with PCI-e 3.0 support, it connects via dual 2x4 external SAS ports to deliver efficient and reliable data throughput.

Designed for environments needing flexible storage expansion, this low-profile controller supports up to 255 drives with no caching or RAID overhead. It offers a streamlined solution for large-scale external SAS deployments where simplicity, scalability, and performance are key.

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.
