Prompt 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 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-

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

Group IP address Network address for the group. The group IP address is used for group administration

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.

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.
Initialize an Array and Create a PS Series Group
1. Gather the information described in Information Required for Initializing a PS Series Array.
2. Click Start → All Programs → EqualLogic → Remote Setup Wizard.
3. Select Initialize a PS Series array, then click Next. RSW discovers and lists all uninitialized arrays that are accessible to the
computer. If no arrays appear, click the Rediscover button.
4. Select a PS Series array from the list, then click Next. You can also search for a specific array or sort the list of arrays. For information
on how to search for a specific array, see Search for a PS Series Array Using RSW.
5. Specify the member information (Member Name, IP Address, Subnet Mask, and Default Gateway).
