What’s the number one problem that keeps virtualization deployments from working as well as they should?
A lack of RAM.
That’s the word from a new survey by vendor VKernel. Though many IT pros worry most about whether their servers have enough CPU power to handle multiple virtual machines, the report argues that memory should be a bigger concern.
Especially with multi-core processors, the average virtualized server is using all available RAM, but has CPU power to spare.
That means the amount of RAM is limiting the amount of virtual servers that can be put on each physical machine at most companies.
The lesson for companies considering or currently using virtual servers: You can never have too much memory.
