Nimble Storage: More than half of mission-critical data is virtualized

Over half the respondents to a recent survey from Nimble Storage said that more than half of their business-critical applications are virtualized.

Seeking cost savings and greater flexibility, more than half of the IT professionals who responded to a survey by hybrid storage vendor Nimble Storage Inc. are virtualizing business-critical applications.

The survey showed that 55% of the 476 respondents -- whom Nimble contacted as members of the company's marketing mailing list -- have virtualized more than half of their mission-critical data, and 66% of respondents expect to do so in the next 12 months. According to the results, almost two-thirds of which were derived from U.S. businesses with fewer than 1,000 employees, databases are the most frequently virtualized workload type, with messaging systems, collaboration and business applications, in that order, following behind.

With regard to virtual machine data protection, the survey found that, while 48% of the respondents are taking VM-consistent snapshots, 70% also rely on host-based backup processes.

Over half of Nimble's survey respondents said they have virtualized more than half of their critical workloads, but another study by Aberdeen Group Inc., cited in an October 2012 article on, found that fewer than half of IT shops have virtualized their databases, email and mission-critical data, though they are increasingly approving projects to do so.

An earlier report on in August 2011 cited an IDC forecast that 65% to 70% of all workloads would be virtualized by 2013.

Respondents to the Nimble survey cited budget restrictions and inadequate IT infrastructure as the top two challenges businesses face in adopting the technology, with network and storage issues each cited as infrastructure obstacles by 54% of survey respondents. Servers and data protection and disaster recovery were cited as obstacles by 38% and 36% of survey respondents, respectively.

Inadequate skill sets among employees and licensing restrictions were also cited by respondents as being among the top obstacles to virtualization.
