RAID 6 is essentially an extension of RAID level 5 which allows for additional fault tolerance by using a second independent distributed parity scheme two dimensional parity Data is striped on a block level across a set of drives just like in RAID 5 and a second set of parity is calculated and written across all the drives RAID 6 provides for an extremely high data fault tolerance and can sustain multiple simultaneous drive failures It is a perfect solution for mission critical applications 12 User Manual ISCSI to SATA II RAID Subsystem RAI D Management The subsystem can implement several different levels of RAID technology RAID levels Supported by the subsystem are shown below Block striping is provide which yields higher performance than with individual drives There is no redundancy Drives are paired and mirrored All data Is 100 duplicated on an equivalent drive Fully redundant Data is striped across several physical drives Parity protection is used for data redundancy Data is striped across several physical drives Parity protection is used for data redundancy Data is striped across several physical drives Parity protection is used for data redundancy Requires N 2 drives to implement because of two dimensional Mirroring of the two RAID O disk arrays This level provides striping and redundancy through mirroring Striping over the two RAID 1 disk arrays This level provides mirroring and redu

D 1 arrays can be striped together to create a single large array consisting of pairs of mirrored drives All writes must go to both drives of a mirrored pair so that the information on the drives is kept identical However each individual drive can perform simultaneous independent read operations Mirroring thus doubles the read performance of a single non mirrored drive and while the write performance is unchanged RAID 1 delivers the best performance of any redundant array type In addition there is less performance degradation during drive failure than in RAID 5 arrays Duplicate data is written to pairs of drives pata DATA bata pata pata pata It Reads can occur simultaneously on every drive 10 User Manual ISCSI to SATA II RAID Subsystem RAID 3 sector stripes data across groups of drives but one drive in the group is dedicated to storing parity information RAID 3 relies on the embedded ECC in each sector for error detection In the case of drive failure data recovery is accomplished by calculating the exclusive OR XOR of the information recorded on the remaining drives Records typically span all drives which optimizes the disk transfer rate Because each I O request accesses every drive in the array RAID 3 arrays can satisfy only one I O request at a time RAID 3 delivers the best performance for single user single tasking environments with long records Synchronized spindle drives are required for R
