The second-biggest data center infrastructure challenge is system performance and scalability. Gartner expects IT organizations to be challenged to support the various growth initiatives as a result of deferred infrastructure upgrades and extended technology refresh cycles in 2009. As a result, they are now dealing with an aging infrastructure or, in some cases, product obsolescence.
Network congestion and connectivity architecture were the next-biggest challenge, driven by next-generation servers with multicore processors and virtualization that require significantly high input/output (I/O). Further exacerbating the connectivity situation is the growth in staff working remotely or going mobile.
The survey found that the three most important drivers of strategic change in data centers were business continuity and availability (50 percent of respondents), followed by cost containment initiatives (37 percent) and maintaining or improving user service levels and satisfaction (36 percent). More than half of the respondents plan to expand capacity at their existing data center site by the end of 2011, and 30 percent plan to build new data centers. The top three technologies that respondents plan to invest in through 2011 are server virtualization (67 percent), application consolidation or rationalization (56 percent) and blade servers (51 percent).
Adams says technologies such as data de-duplication, archiving and thin provisioning (which is enabled by virtualization) can be very helpful for users trying to address data growth issues while at the same time maintaining their cost containment initiatives.
While Gartner did conduct a detailed research into enterprise IT spending budgets earlier in the year, this particular survey of large enterprises asked only to whether the respondent's total IT budget for next year was expected to increase, decrease or stay the same relative to the current year. 44 percent of respondents said it was going to increase, 14 percent said it would decrease, 40 percent said it would stay the same and 2 percent did not know.
