Gartner last month announced the results of an enterprise infrastructure survey conducted with over 1,000 large enterprises -http://www.gartner.com/it/page.jsp?id=1460213 – and they make interesting reading. According to respondents; data growth is the biggest data centre hardware infrastructure challenge for large enterprises. Now, this in itself is probably not surprising – vendors, end-users and other industry analysts have been talking about this challenge for some time. The inescapable truth is that storage demands are growing, and the answer lies somewhere between provisioning greater capacity and making more efficient use of the resources available. What is particularly striking is that 62% of respondents reported that they will be investing in data archiving or retirement by the end of 2011.
