I recently stumbled upon a very interesting seven part series of videos
involving data management. This series
is conducted by Jon Toigo, the “Data Management Institute Chairman and Toigo
Partners International CEO.” This
particular part, and accompanying video, involves data storage needs as a
result of server virtualization.
When server virtualization was introduced, many companies jumped on
board without fully understanding the concept or its effect on storage. However, Toigo explains that server virtualization
has actually led to an increase in demand for storage capacity. Original estimates from 2011 predicted an
increase in demand of 30% annually through 2014. This figure was modified one year later to
300%. At the same time, another firm
predicts 650% estimate growth. These
figures are staggering when looked at from a storage capacity perspective. The original estimate called for 46 exabytes
of total installed external storage capacity.
Once updated, to figure rose to 168 EB or 212 EB depending on which firm
you believe. In this video, Toigo
explains the effect server virtualization has on data storage
requirements. Many of the concepts are
above my limited understanding, but it appears that server virtualization often
depends on data replication as a failsafe.
This replication of large chunks of data is driving the demand for
capacity through the roof. Another problem
is the support for “proprietary functionality in the server hypervisor
software.”
In this
link, Toigo discusses this concept that he describes as another part of the “storage
infrastruggle.” There are several links
on this page, though some require a free membership. One link in particular provides a brief
tutorial on managing a
server virtualization environment. The
rest of the seven part series can be found on the left side about halfway down
the page.
