SearchStorage report: DataCore announces powerful new releases
SearchStorage has done a good write up hitting some of the highlights and also included comments from Jack Fegreus, CEO at Southborough, Mass.-based openBench Labs.
He is in agreement with most of the other analysts who tout storage virtualization as the area of focus in 2009 as he says that DataCore's combining these features into a server-centric approach looks like the wave of the future for networked storage as integration increases between SANs and servers.
Product highlights include:
- x64 versions which support up to 1TB cache
- Transporter feature allowing for offline conversion of any to any physical or flavors of virtual servers.
- Space reclamation capability for DataCore's Thin Provisioning feature

Thin Provisioning: Great concept, but how can it help me?
Thin Provisioning can be an incredibly powerful tool, but as with most powerful technology, care must be employed to assure best practices. Please contact us to understand what these are (after all, we did invent the concept!).To give a practical example, Windows Server is generally installed in a partition of at least 100GB, and often 200GB or more, especially if Exchange Server or SQL Server is installed. However, the initial install may actually consume only 10GB or so. With thin provisioning, the volume can be set to a virtual size of 200GB or more, but it will actually use only 10GB. As the amount of data stored nears a set percentage of full (often 80 percent), the storage system can either notify the admin to expand the volume, or with more sophisticated systems such as 3Par or Compellent, expand the volume automatically. If a volume is increased to 200GB (for that theoretical log file), once the problem is resolved and the log file deleted, the system can automatically shrink the volume again to reclaim the excess space.
If the admin is willing to trust the system, he no longer has to worry about the capacity of specific volumes. He can buy excess capacity for the array as a whole, which can encompass storage for dozens of servers, rather than having to play it safe for each and every server, only to have 50 to 80 percent of the internal or direct-attached storage on each server go unused.
I know what you're thinking. While this is fine for companies that already have a SAN in place, what about smaller companies? Well, there’s an answer there too – storage virtualization software such as DataCore’s SANSymphony can provide similar functionality using existing hardware and with a relatively small overall investment.
