Frequently asked questions - Storage VirtualizationStorage virtualization background <<previous|next>> :Does storage virtualization impair performance or add network overhead to the SAN?
Is the market ready for storage virtualization? Are the products ready?
For the sake of completeness, storage virtualization has also been applied to files and blocks (e.g., iSCSI). On the file side, there are the V-series products from Network Appliance Inc. (NetApp), as well as offerings from PolyServe Inc., Exonet or Isilon Systems Inc. -- those products are utilizing storage virtualization principles with a file focus in a homogeneous environment. On the iSCSI (block) side, it would be fair to include companies like Intransa Inc., LeftHand Networks Inc. and EqualLogic Inc.; each offering homogeneous virtualization products for their own storage boxes.
