About Disk Array Configurations and
Concepts
The Solstice DiskSuite software designed for use with the system lets you configure
the machine's internal disks in several configurations called disk arrays, which
improve performance, capacity, and availability.
Note -
Solstice DiskSuite and other software must be ordered separately.
This section describes some of the most popular and useful of those configurations,
including:
4 Disk concatenation
4 Disk mirroring (RAID 1)
4 Disk striping (RAID 0)
4 Disk striping with parity (RAID 5)
4 Hot spares
4 Hot plug
The DiskSuite software creates metadevices—logical disk devices consisting of one or
more physical disks or partitions from several disks. Once you use Solstice DiskSuite
to create a metadevice, the operating system uses and maintains the metadevice as if
it were a single device.
For instance, you can combine the three disks c1t2d0s2, c1t3d0s2, and c1t4d0s2
into the metadevice /dev/md/rdsk/d0.
