Nexsan BEAST Series, User Manual, Page: 226 / 267

Note SAS, SATA, and SSD disk drives cannot be used in the same RAID array. If your Nexsan High-Density
Storage unit contains a mixture of disk drive types, the Quick Start configuration page will have two or three
Quickstart Options sections, one for each drive type.
►
To perform the Basic Quick Start operation:
1. Using the drop-down lists, set the following parameters:
Number of arrays : Choose the number of RAID sets that you wish to create. The maximum number
depends on the number and size of disks detected in the unit.
Select RAID level : Choose the RAID level that all RAID sets will be configured for. You can choose
from the following:
RAID 0 (striped)
RAID 1/1+0 (mirrored)
RAID 4 (parity)
RAID 5 (rotating parity)
RAID 6 (rotating dual parity)
Notes:
RAID 1+0, also known as RAID 10, is automatically configured if you select RAID 1/1+0
(mirrored) and use an even number of drives, with a minimum of four.
For more information on RAID levels, see Appendix C , RAID levels on page 252.
Number of pool spares : Choose the number of spare disks that will be available to use as backups
in case a RAID disk fails. The maximum number of pool spares depends on the number of disks
detected in the unit.
Number of volumes per array : This setting controls whether or not each RAID array will be further
divided into two or more smaller volumes. The default setting is 1 . The number of volumes per array
can be anywhere from 1 to 10 .
Limit volume size to less than 2TB : This option is unchecked by default. If your hosts do not
support volumes of more than 2TB in size, check this option.
In the Reserve for Snapshots (% of total volume capacity) drop-down list, select the amount of
each volume’s total capacity that you wish to reserve for snapshots. The default setting is 25% . You
can select 10% , 25% , 50% , or 100% . Enabling snapshots also enables replication.
Notes:
Selecting Disabled will cause the Quick Start operation to use all available space in the array for
volumes. To enable snapshots and replication later, you will need to delete at least one volume to
free up space for the snapshot reservation.
For detailed information regarding the snapshots and replication features, see the Nexsan High-
Density Storage Snapshots and Replication User Guide .
2. Click Next .
The New Configuration Preview page is displayed.
3. Ensure that the settings for Arrays , Volumes , Pool Spares , and Volume Access are correct.
