When you transition volumes using the 7-Mode Transition Tool, you should consider certain limits for assessment, such as the number of controllers and hosts that can be assessed simultaneously. For migration, you should review the number of volumes in a project and number of projects that can be run simultaneously.

The following table lists the number of controllers and hosts that can be assessed simultaneously:

Parameter Maximum limit

Number of controllers

50

Number of hosts

20

Number of ESXi hosts

10
Note The maximum number of 7-Mode controllers in a single assessment depends on the number of objects, such as number of volumes, qtrees, quota, and exports.

The following table lists the number of volumes in a project and the number of projects that can be run simultaneously during migration:

Parameter Maximum limit

Number of volumes in a project

160

Recommended limit for the total number of volumes across all active projects in the web interface at any given time

240

Maximum number of active project at any given time

50

Note If you have 50 active projects, you can replicate data from 50 7-Mode storage systems and their associated SnapMirror destinations.

Number of data copy schedules per project

7
