Prompt RAID policy Description volumes from computers outside the local network). The default gateway must be on the same subnet as the Ethernet 0 network interface. RAID policy configured on the first member of the group: • RAID 6 - Of the total number of disks installed in the array, two disks are used for parity and one disk is a spare. The rest are data disks. • RAID 6 Accelerated - Has the same disk configuration as RAID 6, but is used on PS Series arrays that have a mix of HDD (hard disk drives) and SDD (solid state disk drives). • RAID 10 - Striping on top of multiple RAID 1 (mirrored) sets, with one or two spare disks. RAID 10 provides good performance for random writes, in addition to the highest availability. • RAID 50 (Not Recommended) - Striping on top of multiple RAID 5 (distributedparity) sets, with one or two spare disks. RAID 50 provides a good balance of performance (especially for sequential writes), availability, and capacity. NOTE: To use RAID 5, you must configure the RAID policy using the Group Manager CLI. If you are adding an array to an existing group, use the Group Manager GUI or CLI to set the RAID policy for the new member. NOTE: For a complete listing of RAID policies on PS Series systems, see the Dell Technical Report PS Series Storage Arrays: Choosing a Member RAID Policy, available at en.community.dell.com/techcenter/storage/w/wiki/equallogictech-reports.aspx.

volumes from computers outside the local network). The default gateway must be on the
same subnet as the Ethernet 0 network interface.
RAID policy
RAID policy configured on the first member of the group:
•
RAID 6 — Of the total number of disks installed in the array, two disks are used for
parity and one disk is a spare. The rest are data disks.
•
RAID 6 Accelerated — Has the same disk configuration as RAID 6, but is used on PS
Series arrays that have a mix of HDD (hard disk drives) and SDD (solid state disk
drives).
•
RAID 10 — Striping on top of multiple RAID 1 (mirrored) sets, with one or two spare
disks. RAID 10 provides good performance for random writes, in addition to the
highest availability.
•
RAID 50 (Not Recommended) — Striping on top of multiple RAID 5 (distributed-
parity) sets, with one or two spare disks. RAID 50 provides a good balance of
performance (especially for sequential writes), availability, and capacity.
NOTE:
To use RAID 5, you must configure the RAID policy using the Group
Manager CLI.
If you are adding an array to an existing group, use the Group Manager GUI or CLI to set
the RAID policy for the new member.

Group name
Unique name used to identify the group. The name string must be fewer than 64
alphanumeric characters or hyphens. No other characters are permitted. The first
character must be a letter or number.
Group IP address
Network address for the group. The group IP address is used for group administration
and computer access to data stored in the group. You cannot specify IPv6 addresses
when initializing a group. However, you can add host access to a group that is already
configured to use IPv6 addresses.
Password for managing group membership
Password required when adding members to the group. The password must have 3 to 16
alphanumeric characters and is case-sensitive.
Password for the default group
administration account

grpadmin account. The password must have 3 to 16 alphanumeric characters and is case-
sensitive.
Microsoft service user name and password
CHAP user name and password used to enable Microsoft service (VSS or VDS) access
to the group. The user name must have between 3 and 54 alphanumeric characters. The
password must have 12 to 16 alphanumeric characters, and is case-sensitive. Microsoft
services running on a computer must be allowed access to the group in order to create
VSS snapshots in the group or use VDS.
