Hi, If we compare the the most powerful EVA (8100) with the most powerful XP(24000) then:
1. XP has much more front ports then EVA
2. EVA has better virtualization then XP
3. XP is cache oriented 256GB, EVA disk oriented (cache is 8GB)
4. the core components interconnected by crossbar (XP), EVA uses dual controllers
5. XP has much more of everything then EVA, e.g.
physical disks 1152/240, front ports 224/8,
LUNs 65280/2048, cache 256GB/8GB, etc.

In case that was not obvious, I was being facetious (word with all five vowels in alphabetical order :-) here because this is such an open question, answerred many times before.

Feed the whole subject line to google and hit 'i feel lucky' to get for example:

For general purposes comparisons just visit the Hp.com/storage and drill down.

If you like to better understand specific capacity, functionality, performance, connectivity differences, then I'm sure folks here will try to help.

Regards,
Hein.

The EVA is entry level to midrange class disk array and the XP is enterprize class. That is the basic distinction and it drives all other areas as the previous replies mentioned
1. Cost
2. Capacity
3. Performance
4. Manageability
5. Support
6. Upgradability
7. Interfacing
8. Internal design
9. Software
10. Features and capabilities
11. etc. etc.

Each one of these areas can be a large topic on its own.

Pick any of the models in

and look at the "quickspecs" link.
