NWME : Storage is going green. But, it’s not the biggest power hog in a data centre. How much of an energy saver is green storage?
Yoshida : Green storage that we talk about is more about efficiencies. Various studies indicate the storage utilisation among enterprises is only around 20-30%. We provide you with a storage platform using virtualisation to improve utilisation so that you don’t need to buy more storage and use what’s already allocated.
NWME : How do you actually increase the utilisation of storage?
Yoshida : First step is consolidation. You have to consolidate all that storage scattered across the enterprise into a single pool. Then you have to virtualise that pool of storage. We have introduced the concept of thin provisioning with our storage virtualisation platform to increase the storage utilisation and eliminate redundancies. Our objective is to improve storage utilisation by taking advantage of allocated by unused storage capacity.
