Hi everyone,
Has anyone any experience with PowerHA and Hitachi True Copy ?
We plan to install some clusters with PowerHA imbedded TC technology, but as far as i tested the product, it seems to be really light in the management part, compared to what is offered by a more "conventional" cluster.
I already red the redbook "IBM powerHA system mirror" which deals with the True copy feature, but i would like to know if people use it in real production environment?

Thanks for your help !

Oddly enough its the PowerHA 7.1 redbook that does cover it and not the system mirror one. The support wasn't out yet when the system mirror redbook was written.

In the 7.1 redbook its in chapter 14. Hopefully its good as I know the author of it personally....8^).

I know customers that have shown interest in it. I know a couple of customers that have done proof of concepts (including one who did it with the HP rename/rebrand of the combination called continuous access) and it worked just fine. Since I provide pre-sales support I don't always know if they end up putting it in production or not. So I personally do not have first hand knowledge of the combo in production, yet But hopefully some others who monitor this forum will.

Hi Shawn, thanks for your reply,

Well the redbook is named "IBM PowerHA SystemMirror 7.1 for AIX", so i guess we had both, a good part of the title ! ;-)

We are now building one cluster (on a long range), and we'll see if it is as easy to administrate as a classic cluster.
