This would not be true with EMC

Re: Pros/Cons of using EMC Clarion vs. HP EVA SANs
The Clariion are certainly no better/faster/easier to manage than the EVAs so unless they're offering them substantially cheaper and also offering to do the migration for you for free, I'd give it a miss.

Re: Pros/Cons of using EMC Clarion vs. HP EVA SANs
We, in fact, are moving our lower envs to them as I type.
The one thing I've learned about them is - They are very dependent on "pathing". By that I mean they need to see *certain" pvlink paths as primary & the others as secondary. Else they see a lot of tresspass "errors". Now that wouldn't bother me so much, but the Storage Ops team whines about the "size" of their logs - and that has a lot of merit. I guess what I'm trying to say is the Clariions seem to need a lot more "front-end" planning & work.
Performance has yet to be determined as they are still quite new in our env.
My 2 cents,
Jeff

Re: Pros/Cons of using EMC Clarion vs. HP EVA SANs
I think EMC H/W solutions are costlier that HP's and EVA and CLARRION both come in the same segment .
thx,

Re: Pros/Cons of using EMC Clarion vs. HP EVA SANs
in case of a problem, there is always the question: Who is responsible? If you purchase your hardware from different manufactures, you have to discuss your problem with all involved parties. If you have only one supplier, you can address your problem easily.
My 2 cents.
Hope this helps!
Regards
Torsten.

Re: Pros/Cons of using EMC Clarion vs. HP EVA SANs
The support issue "finger pointing" that Torsten mentioned is precisely the reason we purchased an EVA 5000 over what EMC/DELL was offering.
Nothing can be more difficult than obtaining proper support if your shop has mixed hardware vendors with equipment crossing over between vendor hardware.
The pricing was comparable in what we were purchasing, thus support was a deciding issue.
You might note that, in our case, we were able to reduce overall maintenance costs by going with HP's EVA and rolling the maintenance into the current contract.
Expect your superiors to leverage the vendors in question for additional pricing discounts since they are in competition.
FYI - Our EVA purchase was to replace an XP512 that became too much of an expense when expanding was required.
Sorry, I have no Clarion experience.
Best of luck on this.
Regards,

Re: Pros/Cons of using EMC Clarion vs. HP EVA SANs
While I have never replaced an HP EVA with an EMC CLARiiON, I have replaced HP EMA 12000s with a CX700 and am very glad I did. Stability has increased 100% across our HP-UX, Solaris, Windows disk and STK tape SAN environment. We're happy to be rid of SecurePath and now use PowerPath.
Change can be good; don't be afraid to embrace it. Hold each vendor equally responsible for providing you the support you expect and are paying for.
