We are planning to upgrade the hardware and software. VMware to current version, create 4 virtual machine OS Windows 2012 R2 standard. SQL 2014.
Q1) For fail over we need 3 physical server Master and 2 slave?
Q2) For Fail Over it has to be identical server cpu, memory, hard disk, etc..
Q3) We are planning to have the Master and first slave in the main office the second slave we are planning to have in another location distance 120 miles from the main office, we planning to connect via internet. For the virtual server were we created the sql 2014 if the first slave receive a lot of data eg 60GB daily ( our client instead of sending hard copy we are forcing for them to scan and insert into our public portal to our database). How VMware will work for fail over if we receive 60GB of data daily to the first slave how is going to update the second one?
