Appendix D: About RAID 17 Appe ndi x D: Abou t RAI D A Redundant Array of Independent Disk (RAID) provides better performance and reliability from combinations of drives than is possible with the same total storage space without RAID. This Appendix describes the various RAID levels supported by the 6-Port SATA RAID controller. The following table s[...]

Appendix D: About RAID 18 RAID 1 A RAID 1 array is created by copying, or mirroring, a ll data from one drive onto a second drive. This mirroring provides redundancy, ensuring that if one drive fails no data is lost. Howeve r, redundancy also means that only half the total capacity is available. Figure 4 A RAID 1 array A RAID 1 array has no write p[...]

Appendix D: About RAID 19 RAID 10 This dual-level RAID type is created by using two or mo re equal-sized RAID 1 arrays to create a RAID 0 array. Both read and write performance are improved becaus e array striping occurs. However, the performance improvement requires that additional storage s pace be used because the arrays are mirrored. Figure 6 A[...]

Appendix D: About RAID 20 RAID 50 This dual-level RAID type is created by using two or mo re equal-sized RAID 5 arrays to create a RAID 0 array. The top level RAID 0 array shares the load among the second-level RAID 5 a rrays, improving both read and write performance. Parity (Pa n or Pb n ), used in the second level RAID 5 a rrays, provides effici[...]

Glossary 2 1 Glo ss ar y activity See task. array A logical disk created from avai lable space a nd made up of one or more partitions on one or more physical disks. Arrays are typically used to provide data redundancy or enhanced I/O performance. See also container , volume , spanned volume , and RAID signature . Also know n as a container. array i[...]

Glossary 2 2 degraded A redundant array (for example, a RAID 1 array) in which one or more members have failed. The data is intact, but redundancy has been co mpromised. Any further failure would cause the array to fail and result in data loss. dirty data Data that has been written to a cache, but which has not been flushed out to its final destina[...]

Glossary 2 3 impacted An impacted array is one which has been crea ted, but for some reason the initial build operation did not complete. All member driv es are present and operational, and all data written to the array is protected. To opti mize the array, run a Verify with Fix task. initialize Process of preparing a disk for use by the controller[...]

Glossary 2 4 redundant The ability of an array to main tain operability when one or more hardware failures occur. RAID 1 array is an example of a redundant arra y. In the event of a drive failure, redundant arrays can be restored to normal operation by replacing the failed drive and rebuilding the array. rescan Process of updating the current scree[...]
