Systems virtualization will also bring with it speedier adoption of iSCSI. iSCSI has been quietly making inroads into the FC space and will continue to do so while keeping a clear demarcation between its functions vs. those of FC. It's only a matter of time before storage teams will need to deal with both technologies concurrently, if not already.
But storage virtualization seems to have reached a bit of a plateau. Most big vendors have released roadmaps for their products. We know the virtualization strategy that vendors like EMC, HDS, Hewlett-Packard (HP), IBM and Network Appliance are pursuing. So unless someone announces a major change in direction, this space will remain
| relatively calm. Adoption will rise, but not at a surprising rate.
If you implement storage virtualization this year, do it for the right reasons: not because it's cool, but because it offers the ability to create homogeneous storage pools, seamless data mobility and, more importantly, storage tiers that can be tied to the business value of the data they store.
The open-source movement will also play a bigger role in the storage world. Several firms, such as IBM and Sun, are contributing significantly to open-source software. The Aperi project, for example, is aimed at creating an open-source suite of storage management apps.
