Connecting Two Stacks of Engines
121
Setting-Up Two Stacks
Regardless of the number of engines you are planning in your Avid ISIS stack. The following
procedure summarizes the tasks you need to do after you have decided on your IP address
scheme with your Network administrator, see
“IP Addressing With Two Stacks” on page 118
To setup two stacks of engines:
1. Setup and configure each stack separately as you would in a single stack configuration (see
“Connecting ISIS Hardware” on page 67
.
Each for the two stacks connect to the same System Directors.
2. Once the two Management Domains are configured, set the appropriate 10-Gb Link
Aggregation between the stacks with external switches (see
Aggregation Group” on page 103
3. Upgrade your software if you are currently on an earlier ISIS 7500 | 7000 software version
before setting up the Storage Groups in the separate Management Domains (see
7500 | 7000 Upgrade Guidelines” on page 143
).
4. See the
Avid ISIS Administration Guide
for setting up your Storage Groups and Workspaces.
The two stacks of engines are identified using a Domain ID in the Storage Element page of
the Management Console.

The two stacks cannot be part of the same Storage Group. Each stack must have at least one
Storage Group.
Reconfiguring One Stack into Two Stacks
In many cases you do not have to delete your data if you are splitting your stack of engines into
two Management Domains. If you have one large Storage Group and there is enough available
space in your existing stack, you can remove engines, triggering a redistribution of the data to
other engines, see
“Replacing an Engine” on page 186
. This will make the chassis available to be
moved to the other Management Domain where they can be made into a new Storage Group, or
adding to an existing Storage Group in that Management Domain. If you added that engine to an
existing Storage Group in the new Management Domain, a Redistribution will be incurred.
If you have several Storage Groups in your current stack, you can select the complete Storage
Group by removing the engines with that Storage Group to start the new stack.
The following procedure summarizes the tasks you need to do if you have one stack
configuration and want to break it into two Management Domains. First establish your
IP address scheme with your Network administrator, see
“IP Addressing With Two Stacks” on
, then complete these tasks.
