Table 5. Array Configuration (continued)
Prompt Description
Netmask Combines with the IP address to identify the subnet on which the Ethernet 0
network interface resides.
Default gateway Network address for the device used to connect subnets and forward network
traffic beyond the local network. A default gateway is used to allow the Ethernet 0
network interface to communicate outside the local network (for example, to allow
access to 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.
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/equallogic-tech-
reports.aspx.
Table 6. Group Configuration
Prompt Description
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
A password that will override the factory-set password (grpadmin) for the default
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.
