Hello.
Now I’m working at migration from HP XP12 to HP XP 24K (USP V) and HP is very agressive in selling HDP.
Our customer also don’t want to use HDP as a thin provision so we are thinking about benefits you say :
- Simplified LUN management
- Potentially better performance
So I totally agree that HDP vols a much more easy to manage you don’t need now think about IO profile from different hosts to the save group and so on.
But at performance tests we see that LDEV (usual) configuration near20% better than HDP.
If you are interested you can contact me by mail and I can share with you details about out tests and vdbench outputs.

Nice to see some blogs happening. No one has seen me at work in 6 months and I have nothing of value to add right now.
HDS told me that you can only have 128 SSDs.. 32 per BED. I didn’t even get around to asking the price. I just decided to spend some time looking at what would need that wonderful performance.
On a side note, all the investment I made in designing a wonderful Hitachi Storage Cluster solution that has run like a charm will be in vain next week when our applications people ditch it in favour of Microsoft’s CCR. What a sad day it will be for technology. What a wonderful day it will be for me as I wont have any sync TC to worry about for the time being.

Thoughts?

1: Ditto on ease of managment.

I think the midrange folks are much more inclined to oversubscribe Thin Pools than Enterprise customers.

2: Get on Twitter.
