We are in the process of moving all servers (or virtualising physicals) into a central datacenter connected via MPLS.
Currently we are fully redundant on most aspects - RDS Farms, SQL Clusters, multiple DCs, hardware failover for firewalls etc. The cluster itself is a 4-node ESX Cluster.
However, file servers are a notorious pain to achieve some form of redundancy should the virtual machine crash or fail for whatever reason. Naturally if we were using Hyper-V something like Scale-out File Server (SOFS) with Client Access Points (CAPS) would work, but VMWare leaves fewer options.
Is Distributed File System (DFS) really a robust enough method for file server redundancy and if so, what are peoples recommendations for its configuration? Or whatever strategies have people implemented to achieve this?
