3ware Escalade Storage Switch User Guide To exit the 3ware Disk Array Configuration Utility without saving your changes hit Esc. Determining your configuration Caution: Configuring a disk array writes format-type data onto its member disks and overwrites all the files on those disks. Be sure to back up data that requires retention. With a 2-port Escalade Storage Switch you are limited to a twodrive JBOD (Just a Bunch of Disks), or a two-drive RAID 0 or RAID 1 array. With a 4-port Escalade Storage Switch, you can combine two to four disks into a single array. With four disks you can create a four-drive RAID 0 array, two RAID 1 arrays, one RAID 5 array or one RAID 10 array. The 4-port configuration can be duplicated using the 8-port Escalade Storage Switch. In addition, you may also create a five, six, seven or eight-drive RAID 0 or RAID 5 array, or an eight-drive RAID 10 array. The 3ware Disk Array Configuration main display shows the current disk drive configuration. • Available Drives reports independent drives (JBOD) not associ- ated with an array. • Disk Arrays lists any existing arrays along with their member disks and hot spares. 26 www.3ware.com

Determining your configuration
Caution:
Configuring a disk array writes format-type
data onto its member disks and overwrites all the files
on those disks. Be sure to back up data that requires
retention.
With a 2-port Escalade Storage Switch you are limited to a two-
drive JBOD (Just a Bunch of Disks), or a two-drive RAID 0 or
RAID 1 array. With a 4-port Escalade Storage Switch, you can
combine two to four disks into a single array. With four disks you
can create a four-drive RAID 0 array, two RAID 1 arrays, one
RAID 5 array or one RAID 10 array.
The 4-port configuration can be duplicated using the 8-port
Escalade Storage Switch. In addition, you may also create a five,
six, seven or eight-drive RAID 0 or RAID 5 array, or an eight-drive
RAID 10 array.
The
3ware Disk Array Configuration
main display shows the cur-
rent disk drive configuration.
•
Available Drives
reports independent drives (JBOD) not associ-
ated with an array.
•
Disk Arrays
lists any existing arrays along with their member
disks and hot spares.
