Yes, mod20's can be INSTEAD OF software disk mirroring on the HP3000.

Better still, you can use mod20's to mirror the MPEXL_SYSTEM_VOLUME_SET -
something which  cannot be accomplished with MIRROR/iX software.

Also, the mod20 permits dual-controller access to the HP3000 - a feature
NOT available with the far more expensive Autoraid 12H.

Each mod20 supports a maximum of 8 luns - the same limit as the Autoraid12H.

In a nutshell, I highly recommend the nike mod20 disk array.

I suggest dual Storage Processors (SP's) and maximum memory (which,
officially is 64mb per SP, but 128mb per SP works just fine.
