125. ve in the array The size of each block is determined by the stripe size parameter which is set during the creation of the RAID set RAID 60 can support up to 8 spans and tolerate up to 16 drive failures though less than total disk drive capacity is available Table 2 RAID 60 Uses Provides a high level of data protection through the use of a second parity block in each stripe Use RAID 60 for data that requires a very high level of protection from loss In the case of a failure of one drive or two drives in a RAID set in a virtual disk the RAID controller uses the parity blocks to recreate all the missing information If two drives in a RAID 6 set in a RAID 60 virtual disk fail two drive rebuilds are required one for each drive These rebuilds do not occur at the same time The controller rebuilds one failed drive and then the other failed drive Use for office automation and online customer service that requires fault tolerance Use for any application that has high read request rates but low write request rates Strong Points Provides data redundancy high read rates and good performance in most environments Each RAID 6 set can survive the loss of two drives or the loss of a drive while another drive is being rebuilt Provides the highest level of protection against drive failures of all of the RAID levels Read performance is similar to that of RAID 50 though random reads in RAID 60 might be slightly faster because data is
