I am looking to implement a Disaster Recovery site at our remote office location. The plan is to do SAN-to-SAN remote replication going both ways. We however do not have a dedicated WAN link between sites. I'm new to dealing with Telecommunication Vendors and I've never had to setup a point to point WAN link before so I am hoping to get some help from those who have.
A few questions that I have:
1. We only have about 1.3 TB of data and we do not have a high transactional environment, how much bandwidth will I need.
2. What options will I have in regards to a WAN Connection (ie, fiber, T1, DSL, cable, etc...)
3. What would a ballpark cost be to implement the connection and what are the monthly recurring costs?
4. What configurations will need to be done on the firewalls at both ends to allow communication?
Any additional advice and or pitfalls would be helpful as well.
