CDW experts share technical execution best practices:
Build in limits for VM sprawl. Too many VMs can hinder efficiency as well.
Be consistent in technology purchases. While the server virtualization hypervisor and related products are not brand-specific, it‘s a smart move to be consistent in hardware brands and components.
Allocate VMs running a variety of applications to a given host. This will amplify the network and application optimization measures in place.
Avoid single points of failure. SANs should be linked to back one another up; redundant network interface cards (NICs) will keep a host connected should one card fail.
Keep abreast of security developments for the virtualized world. More research is being focused on security at the hypervisor level of virtualization and thereby the improved protection of virtual machines.
Virtualization is a means to an end, not an end in itself. The decision on whether to virtualize comes down to the resources demanded by an application.
How can small businesses know if virtualization is a fit? To answer this question, CDW surveyed nearly 300 small business Information Technology (IT) professionals through Spiceworks, a social network for IT, interviewing those that have and have not virtualized for their perceptions of and experiences with server virtualization.
The resulting Small Business Virtualization Roadmap examines the opportunities and challenges related to server virtualization.
