Virtualization: Take 2.0
I recently read a SiliconIndia comment on virtualization necessity for Indian deployments by Mr. Ahuja of Sun Microsystems (now Oracle) in India. Mr. Ahuja seems to be stating the obvious in the current
practice of implementing | operating datacenters and offers little new
insights. Virtualized datacenter is the only way to realize a cost-effective |
top-performing confluence for data flow. So the industry is doing it for all
the right reasons.
How ever, as I have often commented in this forum, there are
many branches to virtualizing a datacenter. One can always hark back to the OSI
model for understanding the virtualization layers in a datacenter. There is the
infrastructure (physical) layer consisting of copper and fiber interconnects,
power, cooling, cabinets, HVAC. Now a days, these are modularized to the hilt
that there is almost no wastage. The next virtualization is in the active
equipments which includes servers, switches, routers, etc. Multi core / CPU
servers are already common in the market. Cisco has recently started offering
Nexus 1000 series of virtual switches that function separately or in conjuction
with other non-virtualized Nexus series switches. The other important branch of
virtualization is the OS where VMWare, Microsoft, etc., offer products for the
datacenter market. Finally, the application suite is equally important in
virtualizing a datacenter.
Note that the infrastructure layer has its own complexities.
Perhaps it is easier to implement and virtualize the infrastructure within the
datacenter. But access to the datacenter through outside infrastructure is
equally important and essential (reminds me of many windmills in the
Needless to say, these branches of virtualization are
provided by different players in the industry. What is lacking is a total
solution provider for a virtualized datacenter that any government or
commercial entity can approach for services. Currently OEMs like Dell, IBM, HP,
etc., are offering these services but their total solution is not attractive in
price point, in my opinion. Their claimed value addition in offering a total
solution is subjective and can always be exceeded by a local third party that
is more in tune with the localization needed for Indian installations. The
customer interests are better served by a third party solution provider than
the OEMs.
I am lost on the flexible cabling infrastructure comment -is
he referring to a cabling infrastructure that is flexible for moves, adds and
changes (M/A/C), or, mechanically flexible cable? Also, I am lost on the
plumbing comment -is he referring to water cooling? Real time energy monitoring
is already available from APC (Schneider Electric), HP, IBM, etc., that are
also scalable as the data center grows.
As regards to modular, self-contained units, they are
already available today! Dell, Sun, IBM, | many others offer datacenter in a
container that is fully populated with cabinets, cabling, servers, switches,
routers, PDUs (power distribution units), KVM switches, etc. Many have online
configuration tools where you can spec and configure your needs.
Yes, datacenters do need to be virtualized, not because of new buzz words but for the right reasons of accessibility, performance, price and scalability.
