if you use replication technology for a clone of your produciton network, does the DR site typically just contain a replicated SAN, or does it also include copies of all hosts as well, or can it be either, i.e. justDR SAN, or both DR SAN and DR hosts?
Do you need DR hosts if its only your SAN that blows up? i.e. can your production hosts just use the DR SAN if they havent exploded to?
My understanding was that vmware DR setups are used to mitigate the single SAN (single point of failure), but I wasnt sure if the setup typically includes a set of hosts as well?
And what tools "do" the actual SAN to SAN, esxi host to esxi host replication?
