Data growth has long been a concern in the datacentre, but the problem could be exacerbated because of deferred upgrades during the recession, according to analyst firm Gartner.
Meanwhile, datacentre managers also face new network congestion issues as the use of virtualisation and online services grows.
Gartner's research comes from a survey of over 1,000 large organisations this summer, which identified data growth, and the associated increased costs, as the greatest issue facing these firms.
However, the credit crisis over the past several years has hit budgets, and these companies need to focus resources on approaches that deliver efficiency and scalability if demand begins to pick up again in the near future.
"Many datacentre managers were forced to defer infrastructure upgrades and extend technology refresh cycles in 2009 and, as a result, are now dealing with an ageing infrastructure or, in some cases, product obsolescence," said Naveen Mishra, a principal research analyst at Gartner.
Network congestion and connectivity also ranked highly in the survey responses. Gartner said that newer servers with multi-core processors are pushing up I/O bandwidth, especially when virtualisation is used to consolidate even more server instances into each physical box.
More than half of survey respondents aim to expand capacity at their existing datacentre in 2011, while 30 per cent plan to build new datacentres to meet demand, according to Gartner.
Two thirds of respondents plan to invest more in server virtualisation, while more than half are considering application consolidation or rationalisation and investments in blade servers.
