EMC buys another ...

EMC recently purchased closely-held Smarts, an application/infrastructure management solutions company. Compared to the 3 earlier buys over the past year, Legato, Documentum, VMWare, this one seems off-focus to me. What is EMC trying to get into with this purchase ? and why ?

This purchase takes EMC farther beyond storage, archival/search and virtualization and I don't see why customers would prefer an incomplete offering from EMC as against buying a full suite from other vendors.

I just hope EMC has a smart plan that triggered this buy.
