In the Zambeel scenario, the customer will simply increase processing power by adding a module into the top of the Zambeel box. The beauty part is the software to manage all this distributed processing, which Thomas says is at the heart of Zambeels offering.
Virtualization -- the ability to make multiple storage devices appear as one pool of storage to multiple servers accessing that storage -- is the name of the game right now, but is only one part of Zambeels storage management, according to Thomas.
Compaqs VersaStor [a virtualization product] cant provide security or access capabilities to the storage, and this is key, says Thomas. Neither can it take a snapshot, or instant backup, based on meta data, which is the file that tells one how important certain data is.
This is because VersaStor is a block-based system, so it can only look at data in blocks or large chunks, whereas the Zambeel device works on a file level. Moreover, by mid-2002, Thomas expects the Zambeel appliance to offer both file- and block-based virtualization.
The product will be out in beta form in September, with first production expected by the end of the year.
