Day 3/ Session
Economize your storage for a sustainable future
Hubert Yoshida, Vice President and CTO, Hitachi Data
Systems provided insights into data growth and changing requirements, analyzing
operational expense versus capital expense and highlighting the strategies to
save storage for a sustainable future
 Yoshida
gave an interesting example how the data and archival is growing with reference
to volume of data stored by the various presidents of USA. According to him,
while 3 TB of data was archived during President Clinton’s regime, it rose
to 146 TB during President Bush’s tenure and it is expected to grow at
a geometrical progression during the current president Obama.
Yoshida pointed that with the IDC projecting the IT spend
to be growing on CAPEX and OPEX by $300 billion, there would lot of unused capacity
and low utilization of storage.
Yoshida reiterated that hardware costs are only part of the
TCO iceberg, with the ratio of OPEX to CAPEX being 2:1 to 4:1 or more.
He called upon CIOs to economize storage through economically superior storage
architectures, create strategies, roadmaps, architectures and solutions that
actually reduce total ownership costs.
Certain initiatives that Yoshida recommends the CIOs strongly is to drive storage
virtualization, looking into dynamic provisioning, get into data de-duplication
mode, besides active archival strategy to eliminate archive silos with an active
archive solutions that can scale over time and technology evolutions.
Yoshida intended to create CIO’s interest in storage economics particularly
given the evolution of new types of economic reviews to justify large IT spend
with ROA etc. “Freezing of some capital steams, credit, budget cuts, taking
into account hidden costs including labor and maintenance, besides price per
GB etc., will compel one to look at storage economics,” said Yoshida.
He observed that it is essential to keep in mind the cost reduction opportunities
in the storage infrastructure with new technologies. The CTO suggested that
applying economic and financial principles to storage having architectures,
roadmaps, standards etc. one can drive operational excellence.
Yoshida had defined and characterized 33 different types of costs that can be
used to baseline or track storage TCO and pointed that in the current economy,
costs must be recovered within the budget period, while spotting opportunities
for quick pay back.
For instance, he maintained that dynamic provisioning reclaims 30 to 40% of
the existing storage capacity, while the dynamic tiered storage with virtualization
would reduce ratio of tier I storage to tier 2 or 3 storage, reduce license
cost.
