Storwize® V7000 Unified stores up to five times more unstructured data in the
same space with integrated Real-time Compression
IBM announced the enhancement of compressing not only block data on the V7000
but also now it includes the file data on the V7000 Unified. The V7000 was first set up with compression back
in the summer with a big announcement surrounding “Smarter Storage”. This optimization was the same code and
engine that was purchased from a company named Storwize a few years ago.
initially kept the compression appliance that Storwize was first known for in
the market. Using LZ compression with a
RACE (Random Access Compression Engine) providing an optimized real-time compression
without performance degradation. Thus slowing down data growth and reducing the
amount of storage to be managed, powered and cooled.
compression does not require the compression or decompression of entire files
to access the data block. The engine will compress and decompress the relevant
data blocks “on the fly”. As data is
written the RACE engine compresses the data into a smaller chunk and its 100%
transparent for systems, storage and applications.
The V7000 Unified can now deliver a larger compressed
platform than any other mid-range platform.
With compression percentages around 75%, a system that was maxed out at
2.8 PB (960 drives x 3TB each) can now see the system handle up to 5 PB of
Each V7000 Unified with code base 6.4 has the option of
turning on a 45 day trial of the compression software. After setting the license to “45” then you
can add new compressed volumes on the system.
You can also compress data on virtualized storage arrays.
Compression has been part of NAS for a very long time. We have seen compression of files from jpeg
to office documents. But the best part
is the end user will never have to worry about which files needed to zipped or
compressed. Everything that comes through the V700 Unified can be compressed in
line before it writes the data to disks.
A couple of other improvements that IBM announced were the
addition of a integrated LDAP server to V7000 Unified. This now allows customers to use both local authentication
and external authentication servers to allow access to data. Another feature was the ability to upgrade a
V7000 to a V7000 Unified in the field.
If you currently own a V7000 but need to add file access to the system,
IBM will sell you the two file modules and corresponding software to upgrade
you system. Now mind you there is a list of requirements that will need to be
met so check with your local storage engineer for more information. And finally
we now have support for a 4 way cluster on V7000 unified. This allows for more disks to be provisioned
and can compete with some of the other mid-range storage platforms in the
This all together makes a nice round of improvements that
will make life easier for IBM customers. As the V7000 platform matures it looks like IBM
is putting their money where their mouth is and making storage smarter and more
efficient. More to come on this platform
as I suspect we will see bigger things down the road.
