Headache 4: Setting Up Management Tools
Like Rose, Jon Smith takes a very broad view of virtualization. "For me, a server is no different from a hunk of data storage, and I can move it wherever I want," says the CEO of ITonCommand, a hosted IT services provider. "Whether it's running the operating system or it's just data, it's all storage."
Smith says that eventually virtualization technology will enable any data to go anywhere -- on direct-attached storage when high performance is needed, or somewhere on a SAN when speed is less critical and a higher level of redundancy is required.
ITonCommand uses HP BladeSystem c3000 disks for direct-attached storage, and LeftHand Networks Virtual SAN Appliances and LeftHand's SAN/iQ software on an HP StorageWorks array for storage virtualization on its iSCSI SANs.
The company is now standardizing on Microsoft's Hyper-V hypervisor, part of Windows Server 2008, for server virtualization and on Microsoft's System Center Virtual Machine Manager for administration.
The glue that holds everything together, Smith says, is Microsoft's new Virtual Machine Manager for provisioning and managing physical and virtual computers.
"With VMM on a display, a system admin can look at all the virtual servers' hypervisors across my whole environment, all in one spot, and adjust them," he says. "It's pretty cool stuff."
It's cool when it's set up, but getting there isn't so easy, he acknowledges. "System Center is new, and so is [Hyper-V]. It took us a while to figure out how to connect all our old virtual machines into the hypervisor. It's not the easiest setup out of the box."
Smith says continued virtualization at ITonCommand will result in a true "utility computing" model for his clients. "It will take a while, but people will stop thinking of physical boxes running one operating system. Hardware will be nonexistent to the end user. It's just going to be, 'How much horsepower and storage do you want?'"
How to cope: "Find an expert who knows virtual technology and knows Microsoft System Center," says Smith.
