The base license that is provided
with your system includes the use of its basic functions. However, the following extra licenses can be
purchased to expand the capabilities of your system. Administrators
are responsible for purchasing extra licenses and configuring the
systems within the license agreement, which includes configuring the
settings of each licensed function on the system.
The system supports enclosure-based licensing, which allows the use
of certain licensed functions that are based on the number of enclosures
that are indicated in the license. The system supports the following
licensed functions:
- External Virtualization
- The system does not require
a license for its own control and expansion enclosures; however, a
license is required for each enclosure of any external systems that
are being virtualized. Data can be migrated from existing storage
systems to your system that uses the external virtualization function
within 45 days of purchase of the system without purchase of a license.
After 45 days, any ongoing use of the external virtualization function
requires a license for each enclosure in each external system. The system does not require
an external virtualization license for external enclosures that are
only being used to provide managed disks for a quorum disk and are
not providing any capacity for volumes.
- Remote Mirroring
- The remote-mirroring function
configures a relationship between two volumes. This function mirrors
updates that are made to one volume to another volume. The volumes
can be in the same system or on two different systems. The remote-mirroring
function is licensed per enclosure. It allows the use of remote-mirroring
functions on the total number of enclosures that are licensed. The
total number of enclosures must include the enclosures on external
storage systems that are licensed for virtualization and the number
of control and expansion enclosures that are part of your local system.
The license settings apply only to the system on which you are configuring
license settings. For remote-copy partnerships, a license is also
required on any remote systems that are in the partnership.
- Real-time Compression
- The Real-time Compression
function is a separately orderable license that is set on a per enclosure
basis. One license is required for each control or expansion enclosure
and each enclosure in any external storage systems that use virtualization.
With the compression function, data is compressed as it is written
to disk, saving extra capacity for the system.
In addition to these licenses, enclosure licenses are also
required for the Easy Tier and FlashCopy functions on certain models
of systems. These two functions are not tracked by the system and
do not require any additional input to operate. For auditing purposes,
retain the license agreement for proof of compliance.
In addition to these enclosure-based licensed
functions, the system also supports encryption through a key-based
license. Key-based licensing requires an authorization code to activate
encryption on the system. Only certain models of the control enclosures
support encryption. During system setup, you can select to activate the license with
the authorization code. The authorization code is sent with the licensed
function authorization documents that you receive after purchasing
the license. These documents contain the authorization codes that
are required to obtain keys for the encryption function that you purchased
for your system. Encryption is activated on a per system basis and
an active license is required for each control enclosure that uses
encryption. During system setup, the system detects any SAS attached
enclosures and applies the license to these enclosures. If additional
control enclosures are added and require encryption, additional encryption
licenses need to be purchased and activated.
