global vcs
hi, in global vcs with 2 or 3 sites what is the best way to use in data replication storage-to-storage(from a site to other site) or vvr? tnx
depending who is going to look after it
many storages don't support complex replication topologies which could be the limiting factor, however something like SRDF will do just fine. However storage replication offloads the replication task from servers and can have a consistency group across LUNs exported to multiple servers, something what VVR can't do.
VVR on another hand offers more granular control on what you replicate and how, supports multiple topologies but at expense of additional resources required on servers and storage for SRLs, need housekeeping - monitoring, etc and also reporting of VVR leaves better to be desired so keep it in mind
