The potential of virtualization—leveraging the storage area network (SAN) connectivity by creating an abstraction layer between the servers and the SAN and enabling servers in the SAN to view physical storage as a common pool of capacity—has caused great excitement in the storage industry. However, storage technology providers are at odds about how to realize this potential. While many point solutions for virtualization of storage across heterogeneous vendor products are being proposed today, none are complete, and none fulfill the promise of virtualized storage resources. Hitachi Data Systems has introduced the concept of virtual storage ports and Host Storage Domains in the Hitachi Freedom Storage Lightning 9900 V Series of products—storage systems that are equipped to overcome virtualization challenges. In addition, Hitachi Data Systems and parent company Hitachi Ltd. are taking an open, network-centric approach to virtualization, which will concentrate on the virtualization of storage management. This open approach will provide enterprise storage customers with the choice of best-of-breed solutions, and lend itself to collaboration among multiple storage technology providers. In the next few months, Hitachi Data Systems will be rolling out the details of their virtual network storage management layer.
