Mirror set RAID 1, Stripe set RAID 0

Page 133 highlights

Choosing Your Array Type I Stripe set (RAID 0)-An array made up of two or more drives. The stripe set distributes, or stripes, data evenly across the partitions in equal-sized sections called chunks. I Mirror set (RAID 1)-An array made up of two drives. A mirror set stores and maintains the same, or redundant, data in each of its two partitions. I RAID 5 set-An array that is similar to a stripe set, except that it uses parity to provide redundancy. A RAID 5 set must be made up of at least three equal-sized partitions. One chunk is used for parity data for each set of chunks striped across the partitions. The parity chunk is distributed across all drives containing partitions of the RAID 5 set. I Stripe set of mirror sets (RAID 0/1)-An array made up of two or more equal-sized mirror sets that also stripes the data across all drives. I Stripe set of RAID 5 sets (RAID 0/5)-An array made up of two or more equal-sized RAID 5 sets that also stripes the data across all drives.

Choosing Your Array Type
Stripe set (RAID 0)
An arr
ay made up of two or more drives.
The stripe set distributes, or stripes, data evenly across the
partitions in equal-sized sections called
chunks
.
Mirror set (RAID 1)
An array made up of two drives. A
mirror set stores and maintains the same, or redundant, data in
each of its two partitions.
RAID 5 set
An array that is similar to a stripe set, except that
it uses parity to provide redundancy. A RAID 5 set must be
made up of at least three equal-sized partitions. One chunk is
used for parity data for each set of chunks striped across the
partitions. The parity chunk is distributed across all drives
containing partitions of the RAID 5 set.
Stripe set of mirror sets (RAID 0/1)
An array made up of two
or more equal-sized mirror sets that also st
ripes the data across
all drives.
Stripe set of RAID 5 sets (RAID 0/5)
An array made up of
two or more equal-sized RAID 5 sets that also stripes the data
across all drives.
For more detailed descriptions of each array type, see Appendix A,
Storage Concepts
