a remote location can be indexed offline by a TS7700 in the remote location, but with 
the nature if IBM’s tape grid, the derived metadata can be shared by all the nodes on 
the grid. What’s more, the shared knowledge of a volumes location could be used to 
direct the distribution of the indexing workload(s) thereby minimizing tape movement. 
And that is the hidden architectural jewel in IBM’s tape grid. 
 
We believe IBM will add tape data indexing to its content management offerings and by 
virtualizing the location of a virtual volume IBM has taken a small, but fundamental step 
towards a tape content file system. Moreover, IBM has immense and diverse resources 
it can apply to this issue and is well positioned to become the leader. 
 
Sun is of course not standing still in content management, but we have not seen any 
indications of a well-developed competitive strategy for content management of tapes.   

Openness and Accuracy 

Overall, IBM is much more open than Sun about all its storage products, directions and 
strategies. IBM engages in a robust customer advocate program that provides input to 
the development process.  Comprehensive documentation is available to all and 
announcements are public and well promoted. On the other hand, Sun’s approach is 
best characterized as stealth marketing. Most documentation is not available to the 
public, product improvements are not usually publicly announced, and Sun’s virtual tape 
strategy and directions are arcane at best – particularly the future of VSM underlying 
hardware platform which no longer benefits from improvements to the disk array 
version. As such we have only relied on information that is publicly available. We also 
note that Sun’s web site and collateral materials often contain errors regarding VSM. 

Bottom Line 

IBM ranks highly on a vision and execution basis. It has listened well to the market and 
responded with an up-to-date solution. IBM is well positioned today and for the future. 
Sun continues to play catch-up and needs to become more open about its products and 
strategy. Both vendors need to add data de-duplication capabilities.
