Just the topic I need help with. I'm looking for disk storage solutions for
our HP e3000 997/400 system. We're looking to use this 997/400 box for
disaster recovery testing and need to replicate the storage environment of
the production server that is attached to an EMC 3930 frame. The disk
requirements would be 856GB (mirrored 50% usuable) and 144GB (raw 100%
usuable). Currently the 997/400 has four scsi channels (HBA Model HP28696A)
available on two separate Bus Converter.
Any input/advice would be greatly appreciated.
Thank you,
Jacqueline Savinon

I have connected an XP to MPE from OS 5.5, 6.0, 6.5, 7.0 and 7.5 so all OS's
work. Patch MPEMX90 is required to fix a QAM issue with the XP.
With XP256 the only option is direct connect SCSI. The XP512/XP1024 only has
fiber channel (FC) connections so unless you have n-class running 7.5 and
native fiber you will have to convert SCSI to FC using the Vicom SCSI-FC
router.
If you want to also use a SAN solution, Brocade switches seem to work the
best with MPE but you need to use single-initiator zoning. Also keep in mind
that MPE does not currently have HAFO supported (Coming soon for 7.5!!)
This is troublesome for MPE because of the several firmware upgrades you
have to do on switches and XP's per year which means downtime.

The software you are referring to would be Lun Mgr/Lun Security/LUSE/CVS
Business Copy/Continuous Access. We typically run Lun Mgr/Lun Sec/LUSE/CVS
on a windows box using the Remote control software for XP256/XP512. XP1024
uses Command View (from a windows box).
Business Copy/Continuous Access can run from your Remote Console/Command
View station or from the host, including MPE 7.0 and 7.5.

Lun Manager is all that is required so you can configure your luns as is
Remote Control or Command View.
Lun Security is probably required if you use a SAN.
LUSE and CVS are nice to have so you can create custom size ldevs.
Business Copy and Continous Access would be the real luxuries if you want to
implement DR solutions.
