I've had a Snow Leopard server running for the last two years without any problems doing everything from DNS,DHCP,Mail,Web,Ical blah blah. Have just taken the plunge with new hardware (new mac mini server) due to more users, greater storage needs, ect. The company had recently split into two new companies operating out of the same office. Some workers will only be part of company a, some will be part of company b and some will be part of both. As the names (and purposes) of each company are very different, i'm trying to sort out the best way to approach this. Currently, it's a large VLANed network into different segments (server/admin, wireless,wired,voip). Seeing as though I will be adding a thunderbolt raid to the new mini for storage (and both companies would need to store/access it), i'm thinking that maybe a second nic in the mini is the go and having all of company b's data go through that and company a's data through the internal nic. each nic can then resolve to each companys correct dns names ech. is this the best way to do this? obviously, each user will be part of a group structure so technically their access is already limited, im just concerned about the eventual "my dns resolves to company A but i work for B" ect. any thoughts or help would be great. thanks.
