Query on LAN based Hyper-V Replica Server 2012 R2
We have been asked by a customer to setup Hyper-V Replica internally on 2 servers as part of their improved Business Continuity plan.
I understand that the HV Replica scenario is more suited to DR - where the Production site may be unavailable, rather than BC and to do HV clustering we would require a centralised data storage -i.e. SAN. To keep their costs down their Internal IT have asked if we can migrate all their VM's to 1 physical server (Currently split over 2 servers) and then setup a separate 10Gbit link directly between the 2 servers and use the second server as the HV replica - setting a low replication time to reduce data loss. Does anyone have any thoughts on this?

workable but there is approx 15 minute lag

15 minute lag is not a problem - within 2 hours is reasonable with minimal data loss in the event of major hardware failure
So there you go, but have a read of Cliffs post!
You may want to re-think!

Thanks Cliff
There are 3 virtual servers with 1 of these being SQL. Currently emails are with O365 so no onsite exchange server. IF we went for shared storage - i.e. SAS enclosure would this technically be a dual port DAS connected to both servers or would it work OK SMB3 via 1GB ethernet?

we would agree, in the event a VM fails on Production Server, you can quickly turn on the Replica.
Failover clustering does require the prerequisite of centralised data storage, this could be SMB3 file share, not necessarily a SAN.
Well that works, it depends on, on how much value, they give to lost business, with time taken to spin up the replica, and also data loss, between the last replication time.
and finally - Customer/Client is always right!
