Aggregate requirements for an Infinite Volume

A Vserver with Infinite Volume requires at least four 64-bit aggregates composed entirely of HDDs. Understanding the detailed aggregate requirements for an Infinite Volume and its containing Vserver helps you to better use aggregate space.

The following table summarizes the number and purpose of the aggregates required for an Infinite Volume and its containing Vserver:

Number of aggregates	Content	Description
1	Vserver root volume	The Vserver with Infinite Volume requires an aggregate to store the Vserver root volume.
1	Namespace constituent	The Infinite Volume requires a dedicated aggregate to store its namespace constituent.
2 or more	Data constituents	The Infinite Volume creates a data constituent on each additional aggregate that is assigned to its containing Vserver.

Note: You cannot identify individual constituents using System Manager.

When you create aggregates for a Vserver with Infinite Volume, you should keep in mind that you cannot remove aggregates after they are in use.

If you use the Create Vserver wizard in System Manager, aggregates are automatically created according to the following best practices:

•	The aggregates are no larger than 100 TB.

•	The largest aggregate is used for the namespace constituent.

•	The smallest aggregate is used for the Vserver root volume.

•	The aggregates are provisioned as RAID-DP to ensure data resiliency and protection.

If you use the Create Vserver wizard in System Manager to create a Vserver with Infinite Volume that is a SnapMirror destination, aggregates are not created automatically. You must manually create the set of aggregates to match the set of aggregates in the source Vserver while creating the destination Vserver.

In addition, each node has an aggregate for its root volume. Node root aggregates are visible when you display a list of all the aggregates in the cluster.

What namespace and data constituents are

Each Infinite Volume contains a number of constituents. You don't interact with the constituents; you interact with the Infinite Volume, and the Infinite Volume manages its constituents for you. Understanding what constituents exist in an Infinite Volume can help you understand how an Infinite Volume works.

Aggregate requirements for Infinite Volumes in a SnapMirror relationship

You must have the same number and size of aggregates for the source Infinite Volume and the destination Infinite Volume for SnapMirror to work.
