Looking for some guidance or suggestions to configure the best server solution for my home Apple patch. We are a recent conversion from pc's to an all Mac's household consisting of 2 mac pro's, 3 Macbook Pros, 1 iMac and 4 ipads. All Mac's are running lion and really have no need to upgrade to Mt.Lion at this time because everything works across the board just fine. Currently the Mac Pros' have an SSD drive for OS and apps, and 6TB of internal enterprise drive storage (Raid1) with an external GTech G-Raid for backups. The Macbooks also have an external GTech Gdrive-mini for backups with a secondary backup to iCloud. The iPads backup to iCloud. My goal is to avoid killing our wifi bandwidth doing backups etc, so that's the one reason I have not ventured into a NAS solution. Rather than having to manually admin each system updates etc I figured it might be worth looking into OS X server. Where can I purchase Mac OS X server for lion? and will this be the best server solution for my home systems? I plan on using my Mac Pro as the server. Thanks.
