Isn't this what Kroger is doing?  Aren't they using SAN extenders to
make the storage at the DR site look like it is in the same room with
the ONStor cluster?  I believe they are using DM to mirror a volume from
one data center to the off site.  Then, as Jonathan said, in the event
of a declaration they would have to use vol_import, etc.

The only way to do this is to make the DR LUN(s) visible and owned by
the primary cluster.  It is unlikely that we would have a FC-based
mirroring problem at that distance since we can handle serious latency
in this layer, but there may be SAN/LUN discovery issues that we have
not seen before as this has never been attempted.  If we went this
route, the mirror target would not be usable by the DR cluster without
importing it in the event of a failure.  They would then have to create
new NFS/CIFS shares at that time and there would be no ability to resync
the mirror after the primary cluster came back.

The data rate change is estimated currently at 15% - 20% per day.  While
that is a file number and not block number we shall see what the real
block change rate is soon.

=20

The customer is WANTING to use the FC because they do not want to use FP
ports to transfer data.  They spent the $$$ for the direct Fiber run and
just want to try and use it more than they are.  The idea is separation
of client access via the front end and replication / data volumes via
the back end.

=20

The thought is if we can DM between to volumes that are not in the same
VSVR via IP, is it possible to do it over the FC and if not how
difficult would that be.

=20

The customer knows we do not currently do this.  If this is simply just
not possible, then I can tell them that.

Data Mirror is only supported between volumes in the same cluster.

More over, the volumes have to belong to the same virtual server.

=20

I don't know if we have any experience connecting a filer to storage=20

that is so far from the filer.

=20

Is their rate of change such that using DMIP is not practical?

Current situation:

=20

current DMIP customer has primary and DR site on their campus
environment.  Primary site is a 2260HA, DR site is a single 2260.  DR
site is 1 mile away (it is a BIG Campus).  They are having current DMIP
issues.  The DR site is NOT clustered to the primary site.

=20

What they would LIKE to do

=20

Let me preface this first with, I know it is 5280 ft.  The customer
wants to separate replication traffic from user traffic.  This is
currently no being done because they are dedicating a single GiGE for
DMIP.  They WOULD LIKE to run Data Mirror over the dark fibre they have
directly between the primary and DR site.  They are currently doing this
with their block data in a synchronous solution on Xiotech.

=20

1. Can we use Data Mirror via FC to volumes not in the same Cluster?

2. If their FC environment is fast enough with low latency is there an
issue?

=20

If we could do this, it would be very helpful to the customer.
