we got sone superdomes ,
currently testing with 3Par storage :
we need for a certain databases ( oracle DB ) the highest speed .
former we had XP Storage with ( A-Sync) CA .
we prefere to use LVM HostBase Mirroring .
are there any possibilities to set the LVM HBM also A-sync ?? taking the risc for corrupt data we know ..
we notice the latecy between the 3Par is slowing down ....
can anyone advise us in this ??

As far as I know, no, you cannot force mirrors to async mode with Mirror Disk/UX.
I think you would actually have poorer performance with host-based mirroring than with array based mirroring.
If you are noticing a performance lag with your 3-par deivce, perhaps that is worth a call to HP.

OK Thanks .
The 3 Par work fine .
But even a small delay of 2mS ( latency) in write between two Datacentra can be a problem with millions and millions of writes , that's why we would like to setup for this particular database a A-sync host Base Mirror like Linux is able for .
Unfortunately not available on HP-UX as far as I know?
