Stripe Breadth: Specify how much data is written to or read from each LUN in storage
pools that have this anity tag (or each LUN in the custom storage pool) before
moving to the next LUN. This value can aect performance. If you’re not sure what
value to use, accept the preset value.
5 If the Volume Failover Priority pane appears, arrange the list so as few SAN volumes as
possible have the same metadata controller rst on their failover priority lists, and then
click Continue.
6 In the Setup Complete pane, click Continue.
Xsan Admin displays a summary of your SAN conguration and the new volume is
mounted and ready to use in the Finder on all clients and metadata controllers.
For information about creating additional volumes, see “Adding a Volume to a SAN” on
page 53.
Step 10: (Optional) Set Up SAN Status Notications
Xsan is initially set to notify the administrator by email when the status of the SAN
changes. You can have notications sent to additional email addresses or text-
messaging addresses using an SMTP server, and you can choose conditions that
trigger notication to each address. If you don’t want to customize notications now,
you can do it later.
For instructions, see “Setting Up Status Notications” on page 97.
Step 11: (Optional) Assign Folders to Anity Tags
If you want to force les to be stored in specic storage pools, assign the anity tag of
the pools to a folder. Then, les that users put in the folder are stored only on storage
pools that have that anity tag. For instructions, see “Setting Up a Folder Anity” on
page 57.
Step 12: (Optional) Set User and Group Quotas
You can set up quotas to control how much space on each SAN volume is used by
each user or group. For instructions, see “Setting SAN User and Group Quotas” on
page 79.
