While I
mentioned in my previous blog that any size of data is no problem, I often get questioned
upon how to store and manage the huge volumes. This is a typical concern of an
enterprise faced with increasing data size.
Storage vendors
have seen and known this problem as it grew, and have scaled-up or rather scaled-out
to help handle this massive growth. Both NAS and SAN vendors have gone beyond
the traditional methods of upgrading the storage infrastructure by adding
additional shelves and disks. The challenge that the traditional method has is
that you end up upgrading capacity with shelves and disks with limited
enhancements in processing power. This ends up in performance reduction.
The Scale-out
method helps upgrade the storage by adding new nodes which include processing
power, memory and capacity, thereby keeping the overall performance consistent
with practically no dip in user experience. This is true for both SAN and NAS
based storages. These storages can be expanded to PBs on a single storage, or
even a single file system, by simply plugging in a new node. It is viable commercially
also, as the cost per GB goes down as you keep adding more nodes.
So don’t worry
about handling your Big Data as the storage devices are now available to store
them more efficiently.
