This article is part of the Virtual Data Center issue of October 2010, Vol. 27
When it comes to virtualization storage, you can choose from network-attached storage (NAS) and numerous storage area network (SAN) architectures. Shared storage is often considered ideal for virtual infrastructures, because it allows virtual machines (VMs) to use storage outside of a single local disk and take advantage of important virtualization features. More on virtualization storage Virtualization storage tutorial Storage for virtualization: New vendors, new protocols Costs savings with virtualization storage management Tackling server virtualization storage problems Management is an important factor in shared storage. Administrators will need to create, assign and track a proliferation of logical unit numbers (LUNs), so virtualization storage should include mature and intuitive tools that support fast, error-free management. Although single-vendor storage for virtualization can often leverage homogeneous tools, mixed storage environments need tools that support a heterogeneous environment. Cumbersome tools or tools that ...
