I saw your note that you are looking for sources of information on the subject of storage and virtualization. Here are two books that pertain to storage, virtualization along with related topics including data protection (backup/restore, BC, DR), performance and capacity planning as well as cloud among other items.
Watch for my new book that will be out this summer titled Cloud and Virtual Data Storage Networking (CRC).
An index of free tips, articles, videos, podcasts and interviews pertaining to storage virtualization among other related topics can be found at Storageio.com. These include items seen on ITKE and other venues.
