And with 3par recent track record for delivering features late Q3 is not likely.

It seems odd to me that compellent would be coming in at 1/4 to 1/5 the cost or 3par which is supposed to be a cost competitive array

I generally agree with that statement.

Though with the public announcement they made I would think that they have to deliver.

My guess is that the corollary to this is q3=3.1.4 and that 3.1.3 in any version will never hit ga, and was just a testing/transition os

HP guy working on our system today mentioned they plan to release it to public as 3.1.3 MU1 on June 30.

I'm already seeing the 3.1.3 (MU1) ISO file up on HP's FTP servers as of June 6, so (in theory) it should be good-to-go.

As I mentioned the other day, I got upgraded to v3.1.3 MU1 on a new 7200 (which had 3.1.2 MU3 on it from the factory) - I was due to get V3.1.3 P01 but got MU1 instead on the day.

Unless there are major price cuts coming on flash drives I don't understand this $2/GB either - they've only just reduced the price of the 100GB SLC and its now 15GBP/GB - so over $23/GB - there are discounts of course but nobody gets 90% discounts. The 400GB MLC drive seems to be about the most cost effective at the moment at about $10/GB (list).

I hope they turn it on for other arrays - since they claim the ASIC is doing the heavy lifting I don't see the CPU in the array as an issue - unless it needs more control memory to store this index in which the 7450 has a lot more of - 32GB total cache per controller rather than the 12GB and 16GB of the 7200/7400's respectively. Of course if it does, they could turn on the 2 extra cores per controller (+ the 2 HT cores) that they've turned off on the E5-2428L CPU's that are in the 7200 nodes. It does at least offer some hope in that it says "for no extra cost" or words to that effect.

I also note that on CalvinZ's blog (http://h30507.www3.hp.com/t5/Around-the ... 5h10PldUc8), he says:-

"We are offering a 5 year warranty on all SSDs."

Which might only be for new drives or just be limited to the eMLC and cMLC drives announced over the last 6 months - but not the existing/future SLC/MLC models. I wish people would be more explicit/accurate with what they promise to avoid the likely disappointments its likely to generate.

We need CalvinZ to become a regular contributor/hp-rep here - if you see him Richard - get him to join.

Indeed. It would be nice to have someone like calvin floating around.

I think the issue with dedupe on the 7200/7400 is the lack of control memory. If that is the case, I would expect to see it on the 10400 and 10800 before long though.

Time will tell if its a technical obstacle, or a business decision not to offer it. If no one but 7450 owners get it, then its purely a business decision not to reduce the cost of their spinning disk arrays

I posed this question regarding dedupe coming to the other arrays on LinkedIn and the hp storage forum.

Calvin zito replied saying the range is polymorphic, as in all features are the same across the range, although saying that, this announcement concentrated on the 7450, stay tuned for any further announcements.

Which to me says it should be coming?

One would hope.

Truthfully while it's reached a point of ridiculousness, there is a reason emc has different platforms for different purposes

The dedup feature release in my eyes was purely a marketing decision. My guess/opinion is that it will be released to the rest of the StoreServ line later in the year. -Justin
