Tiered storage 'can increase utilisation and optimisation of assets'


02 Dec 2009

Intelligent tiered storage is, in one expert's opinion, the movement of data, manually or automatically, from a high-cost to low-cost system, in order to increase utilisation and optimisation of storage assets. This process should be smooth and cause no downtime to users, according to Tony Asaro, founder and senior consultant at the INI group.

Writing on his Hitachi Data Systems (HDS) blog, Mr Asaro suggests some factors which make intelligent tiered storage ideal. Firstly, he says, the average data centre will run at less than 50 per cent utilisation of storage and, secondly, 60 to 80 per cent of all data created is usually redundant 90 days after its first use.

By implementing a tiered storage system, companies save "literally millions of dollars," according to Mr Asaro. However, few companies have taken up what appears to be an attractive method of data storage.

Mr Asaro, who puts forward the HDS USP V product as one viable option for tiered storage, writes: "The goal of intelligent tiered storage is to significantly drive down overall total cost of ownership."

Another HDS blogger, Chris Sweetapple, last week claimed that more could be done to improve the destruction of the 60 to 80 per cent of data that is no longer required by a company.
