Configure replication of 2 EqualLogic SANs located on different subnets

I have 2 EqualLogic SANs located in 2 different offices. Offices connected via vendor's MPLS. The SANs are only connected to their dedicated Dell PowerConnect 5424 switches.
I need help with configuring a VLAN beween 5424 (iSCSI) and 5448 (data, Internet, MPLS) to enable the flow of iSCSI traffic from one office to the other. Routers' configuration will be changed by the vendor.

Unless you have 1GB pipe between the offices iSCSI over VPN will not work. 1GB is min. requirement and the latency over the VPN will cause write errors for iSCSI.  Unless you're doing this for backups and not actual iSCSI traffic I would advise against it.

I think the EqualLogic SANs do allow for low bandwidth/high latency replication, but you still need to be sure that the bandwidth/latency/replication set equation makes sense.  What is your dataset size for replication?  (Size of changes to be replicated).  What is the speed of the MPLS connection.

I am faced with the same situation, I currently have both SANs in the same office to do the initial replication I have them on different subnets right now joined by a Cisico 2811 router.  Thos I can ping each san from the other side I can not get replication to run as the replication tells me it can not see the partner.

Of course I don't have 1 GB connection. Vendor (Dell) told us that the existing bandwidth should be Ok after initial sync in the main office.
The question is about VLAN.

Not sure about your San but usually replication is done via the controller so ad long ad the controllers see each other it should work in most configurations although it may be different with your San

Replication is not done through the controllers.
The question is about how to configure Dell 54 and 27 series switches to be able to pass the iSCSI traffic to the vendor's router.

can you setup a static route on your side and add the iscsi subnet to the MPLS routing table.

In my question: "Routers' configuration will be changed by the vendor."
Routes are edited by a vendor.
I am having challenges with configuring the Dell switches. The most current configuration is PC5424 (iSCSI)-PC3548 (data, MPLS connection), on one side, and PC5424 (iSCSI)-PC5448 (data, MPLS).

I finally figured it out with Dell's tech support. It was in the proper configuration of VLANs on the connection/exit ports, as well as some link aggregation settings.
