I'm trying to boost our archiving infrastructure by migrating from mixed virtual servers (journaling, FSA, mailbox archiving) to a physical cluster. My vault stores are on a NAS and my databases are on a separate sql cluster, so I don't need to worry about moving those. However, my indexes are located on the virtual servers. My plan is to build an active-passive cluster to which I'll move the indexes. This will be used for mailbox archiving and journal archiving. Then I'll have a virtual server that does just fileserver archiving. I'm hoping that I can let the virtual server use the index from the cluster rather than having it's own disk -- this is so that i don't have to have a large disk on the vm, and also so that i don't have to try splitting the existing index. So my question is whether this will even benefit me to have my FSA separated out from the mailbox archiving if it's using the index resources of the cluster. Or at that point, am i even offloading any processing by having FSA tasks on the virtual server?
