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
