Active-Active High Availability for the HP XP7 Disk Array

I have a soft spot for our HP XP Disk Array family - I was part of the team that brought the XP into the HP portfolio and kicking out the previous solution was just plain fun.  SO when the XP team came to me and asked if I could introduce some new functionality today, I said "Heck yeah!".  And what I have to show you is pretty cool stuff. 


Imagine being able to replicate between two arrays (either in the same data center, across campus, or 100km away) and with multi-array virtualization that allows active active access to virtual LUNS across those two XP7 arrays. What I just described is the new Active-Active High Availability Solution for the XP7.  And I have a ChalkTalk that gives a bit more about what it is. 



Pretty cool stuff, huh?  And again, we accomplish this without hardware or an appliance (which is what EMC VPLEX needs) or  with proprietary drives/middleware (like EMC PowerPath).  The solution simply requires hosts with industry standard multipathing drivers and industry standard clustering software - the XP7 takes care of the rest.

I did a blog post with a ChalkTalk introducing the XP7 that is worth a look if you haven't seen it already. I also did a follow-up post and ChalkTalk focused on XP Always On Disaster Recovery with Online Data Migration

I'd like to post a question about the output of raidcom cli on a XP7 storage : in which place/forum/blog can I post my issue ?


thanks a lot


P.S: the question is (see the output about "VIR_LDEV"): has the XP7 a historical memory ? If I delete the lun, how the storage can remember that the "fa:01" ldev WAS a virtual device ? thanks a lot...


[CGESTP83]root@sgestp83:/# raidcom get ldev -ldev_id fa:01 -ICA360
Serial# : 350550
LDEV : 64001 VIR_LDEV : 65534
SL : -
CL : -
SSID : 000A

ok, in the meanwhile I ask to HP Labs and it's necessary to do the following commands:

- ... unmap the disk ...

- raidcom map resource -ldev_id 0x4444 -virtual_ldev_id 0x4444 -IH1

in this way, all the "historical information" of a specified lun will be deleted
