FOCUS ON STORAGE

technology. We find sparsity
in the data that enables us to
significantly reduce the size of
storage with compression. To limit
compression to secondary storage
or offline data does not make
sense. Data entering clouds may
not have been determined to be
primary, secondary or offline.
Following the deduplication phase, the unique data
writes are analyzed by IBM's
Real-time Compression* Engine
(RACE), which has been improved
and optimized to take advantage of
our FlashCore technology. This is
similar to the compression that has
been available with our Storwize*
family for six years and recently
available with XIV products.
ISM: What improvements
have been made to optimize
performance?
AW: We offer larger caches above
compression to store data immediately as it's received. We have

made several algorithmic tweaks
to improve both the compressibility and performance. We use
compression accelerator cards,
which allows us to do a full gzip
compression as data enters.
If we only did software compression, we would be forced to
sacrifice compressibility for a
quicker but less efficient algorithm. Using RACE, we maintain outstanding compression
effectiveness and run at hardware
speed. We don't have to perform
background scrubs or recompress
the data at some quiet time in the
storage device.
Once this is all done-in
microseconds-we write to the
FlashSystem. In a hyperscale
environment, creating snaps of
volumes is a common task, and
a large part of the Hyper-Scale
Manager capability. To maintain
the data-reduced model and lessen
the need to redo the process for
snapshots, our virtualization tech-

&

As part of its
deduplication
technology, IBM
has identified
over

200
patterns
produced
by OSes,
applications and
databases that
are removed at
the beginning
of the in-line
reduction
process

nology can do snapshots at the
compressed data level.
The grid architecture brings
triple-redundant processing
nodes (built over commodity
servers with powerful 2.3 GHz,
10-core processors) with large
cache vaults protected by backup
battery modules.
ISM: What drives the data
flow between the processing
nodes and the FlashSystem
solution?
AW: A redundant InfiniBand-based
interconnect fabric running at
Fourteen Data Rate (FDR) speeds.
The FlashSystem storage brings the
well-adopted multilayer redundancy for the data storage, adding
to the overall enterprise-class
resiliency, as it has built-in
dual-controller redundancy over
2-D RAID with IBM hardware RAID
technology at the MicroLatency*
module layer.
The enterprise-class expectation of hyperscale cloud technology is difficult to achieve with
simple, off-the-shelf SSDs and
drive controllers built with opensource technology. IBM's experience suggests that to achieve the
reliability and latency demands
in hyperscale cloud, you need
built-for-purpose controllers and
modules. Failure of half of a flash
chip should not drive the need
for replacing the whole flash
module as it does with a consumer-grade SSDs used in current
cloud implementations.
FlashCore technology enables
A9000 to survive many flash
failures, including entire flash
packages. More importantly,
we have IBM research-designed
health binning, heat segregation
and dynamic read-level shifting
designed into the controller to
make adjustments and maintain
consistent service. These technologies meet the cloud expectation
of simplicity and self-healing.
