If you have RAID 6 configure it is because you define RAID 6 using at least 4 HDDs and using Array Configuration Utility An Controller Card for example P400, P800 and others have the capability to create RAID 6 but if you don't need it yo don't use, you can define RAID 0, RAID 1, RAID 5 in your controller so in case (future) you will need RAID 6 you can use your controller to create that RAID 6

Minimum number of disks: 4 Pros: Even higher redundancy than RAID 5. Dual parity allows the failure of two drives in each RAID 6 array while striping increases capacity and performance without adding drives to each RAID 6 array. Like RAID 50, a RAID 60 configuration can accommodate 8 or more drives, but should only be used with configurations of more than 16 drives. RAID 6 (Data Striping with Additional Parity) –.

If one disk 2015-01-13 · The RAID 5/6 Write Challenge. One potential downside of RAID 5, and especially RAID 6, is the extra writes that are generated. Remember, a write operation, once the SSD has reached a steady state, is the slowest part of flash I/O since each write requires an erase (another write with zeros) and then the writing of the actual data. RAID 5 has a 4 factor penalty on writes.

RAID 6. Applies striping with double parity technique. RAID 6 requires at least 4 drives; it is nearly identical in setup to RAID 5, however, RAID 6 provides increased reliability by utilizing one more parity block, which allows it to withstand two drives dying simultaneously and have an operational system remain accessible.

On an on-going basis system administrators will be getting request to increase the disk space on a server. In this article, let us review how to add new physical disks and create a virtual disk with a RAID configuration on an DELL PowerEdge Server using PERC 6/i Integrated BIOS Configuration… RAID 6 Arrays.
