IBM Storwize V5030 User Manual

30 Implementing the IBM Storwize V5000 Gen2 with IBM Spectrum Virtualize V8.1
1.7.4 Easy Tier
IBM Easy Tier provides a mechanism to seamlessly migrate extents to the most appropriate
tier within the IBM Storwize V5000 Gen2 solution. This migration can be to different tiers of
internal drives within IBM Storwize V5000 Gen2 or to external storage systems that are
virtualized by IBM Storwize V5000 Gen2, for example, an IBM FlashSystem 900.
The Easy Tier function can be turned on or turned off at the storage pool and volume level.
You can demonstrate the potential benefit of Easy Tier in your environment before you install
Flash drives by using the IBM Storage Advisor Tool. For more information about Easy Tier,
see Chapter 9, “Advanced features for storage efficiency” on page 437.
The IBM Easy Tier feature is licensed per enclosure.
1.7.5 Storage Migration
By using the IBM Storwize V5000 Gen2 Storage Migration feature, you can easily move data
from other existing Fibre Channel-attached external storage to the internal capacity of the
IBM Storwize V5000 Gen2. You can migrate data from other storage to the IBM Storwize
V5000 Gen2 storage system to realize the benefits of the IBM Storwize V5000 Gen2 with
features, such as the easy-to-use GUI, internal virtualization, thin provisioning, and copy
services.
The Storage Migration feature is included in the base software, and no license is required.
1.7.6 FlashCopy
The FlashCopy feature copies a source volume on to a target volume. The original contents of
the target volume is lost. After the copy operation starts, the target volume has the contents of
the source volume as it existed at a single point in time. Although the copy operation
completes in the background, the resulting data at the target appears as though the copy was
made instantaneously. FlashCopy is sometimes described as an instance of a
time-zero (T0)
copy or
point-in-time (PiT) copy technology.
FlashCopy can be performed on multiple source and target volumes. FlashCopy permits the
management operations to be coordinated so that a common single point in time is chosen
for copying target volumes from their respective source volumes.
IBM Storwize V5000 Gen2 also permits multiple target volumes to be FlashCopies from the
same source volume. This capability can be used to create images from separate points in
time for the source volume, and to create multiple images from a source volume at a common
point in time. Source and target volumes can be any volume type (generic, thin-provisioned,
or compressed).
Reverse FlashCopy enables target volumes to become restore points for the source volume
without breaking the FlashCopy relationship and without waiting for the original copy
operation to complete. IBM Storwize V5000 Gen2 supports multiple targets and multiple
rollback points.
The FlashCopy feature is licensed per enclosure.
For more information about FlashCopy copy services, see Chapter 10, “Copy services” on
page 485.
