4 Data migration licenses
This chapter provides information on data migration licenses including license types, license
installation, and license use.
Types of data migration licenses
Data migration license keys are based on an MPX200 blade serial number. The licenses are shared
between two blades in the same MPX200 chassis. The two types of data migration licenses are
capacity-based and array-based.
Capacity-based licenses
Capacity-based licenses allow you to migrate data up to a specific limit designated by the applied
license key. This type of license is available in variants of 1 TB and 5 TB capacities, which can be
consumed by one or more migration jobs that you create. Every time you configure a data migration
job, the available capacity is reduced by an amount equivalent to the size of the source LUN being
migrated. The MPX200 does not allow you to add migration jobs when the job size exceeds
available migration licenses.
Array-based licenses
For large storage arrays, array-based licenses are more cost effective than Capacity-based licenses.
Array-based licenses allow you to migrate unlimited amounts of data to and from the specific array
that is licensed. This license SKU is available as a single-array license SKU. You may purchase
multiple single-array license SKUs, generate license keys, and load them on the MPX200. Each
single-array license can be tied to a specific array. The licensed array may be used as either a
source or destination array while configuring jobs for data migration.
Array-based licenses allow you to migrate data in and out of the specified licensed array. For
example, consolidating three or four source arrays onto a single destination array requires only
one single-array license on the destination array.
You would consume multiple single-array licenses under the following conditions:
•
Each single array license is valid for one MPX200 chassis. If you have storage arrays with a
large number of ports (for example, EMC DMX, HP-XP, and so on) and want to use multiple
MPX200s for data migration, you must purchase multiple single-array license keys for each
MPX200.
•
If you present one set of LUNs to the MPX200 from the same array from one set of storage
array ports, and also present a second set of LUNs to the same MPX200 from the same array
from a different set of storage array ports, the MPX200 detects the LUNs as two different
arrays. You must purchase multiple single-array licenses for the same storage array.
Types of data scrubbing licenses
Data scrubbing license keys also include capacity-based and array-based licenses.
Capacity-based licenses
Capacity-based data scrubbing licenses allow you to scrub the data up to the licensed capacity.
A capacity-based license is consumed based on the size of the data LUN being scrubbed. For
example, if you have a 5 TB data scrubbing license and scrub a 500 GB LUN, 500 GB of the
license is consumed and 4,500 GB of the license remains available for future use.
Array-based licenses
Array-based data scrubbing licenses allow you to scrub all LUNs within that array, regardless of
array capacity. An array-based license is consumed when it is allocated to a specific array.
