RAID 10 striping
RAID 10 (one-zero) is a mirroring feature with striping used for
mainframe environments. Four Symmetrix devices (each one-fourth
the size of the original IBM device) appear as one IBM device to the
host, accessible by way of one channel address. Any four devices can
be chosen to define a group provided they are equally sized, same
type (for example, all 3390), and have the same mirror configuration.
Note: “Symmetrix RAID 10 for mainframe systems” on page 196 contains
