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 uses enclosure-based licensing, where
functions are licensed according to the number of enclosures in a
system that are permitted to use a licensed function.
The system supports the following
licensed functions:
- FlashCopy
- The FlashCopy function copies the contents
of a source volume to a target volume. For the FlashCopy function,
the number of licenses must be equal to the total number of control
enclosures, expansion enclosures, and any enclosures in any virtualized
storage systems.
- Remote Mirroring
- The remote-mirroring function
configures a relationship between two volumes. Updates that are made
by an application to one volume are mirrored on the other 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 plus the number of control and expansion enclosures
that are part of your local system. For example, if the system is
made up of one control enclosure, one expansion enclosure, and one
virtualized storage system that is itself made up of two enclosures,
then four licenses are required. The license settings apply only to
the system on which you are configuring license settings. For remote-mirroring
partnerships, a license is also required on any remote systems that
are in the partnership.
- Easy Tier
- The Easy Tier responds to pools that
have a mixture of flash, enterprise, and nearline storage in any combination.
The system automatically and nondisruptively moves data between the
MDisks to optimize performance. For example, Easy
Tier moves frequently accessed data from enterprise or nearline MDisks
to flash drive MDisks, thus placing such data in a faster tier of
storage. For the Easy Tier function, the number of licenses must
be equal to the total number of control enclosure, expansion enclosures,
and any enclosures in any virtualized storage system. For example,
if the system is made up of one control enclosure, one expansion enclosure,
and one virtualized storage system that has two enclosures, then four
licenses are required.
- 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 storage systems
that are being virtualized. For example, if the system is made up
of one control enclosure, one expansion enclosure, and one virtualized
storage system that is itself made up of two enclosures, then two
licenses are required. 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.Only Lenovo Storage V5030 systems support external virtualization.
- Compression
- The 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. Only Lenovo Storage V5030 models support compression.
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. Only Lenovo
Storage V3700 V2 XP and Lenovo Storage V5030 models support encryption. Verify that you have
the appropriate model before purchasing a license for 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.
