That's not to say there are no pitfalls and challenges with virtualization. Because virtualization puts a strain on shared storage, Moran says it's crucial to have a thorough understanding of storage needs and the necessary management skills before embarking on a virtualization project. It's important to identify potential storage bottlenecks and, to avoid confusion, set up a standard naming convention for data stores.
"When you're setting up storage for virtual environments, don't call your data store 'Mike's data store' or "Dan's data store'," Moran says.
Kronos was also careful to avoid virtual server sprawl, which can eliminate many of the cost savings and benefits of virtualization. The IT team set up an Excel spreadsheet to track usage and set up chargeback mechanisms so users would essentially be billed for usage. "Everyone wanted a virtual machine," Moran says.
