Good morning good people! I need your combined expertise and help for a buying /modding decision, please. The situation: I bought an old Xserve (2.1, early 2008), currently running Lion Server and it serves as mediaserver (Plex + musicDB for Sonos) at home. Also included in the package was an old Apple RAID. As its HDD capacities are rather limited and just too small for my intended use, I am looking for an external RAID upgrade. However external RAIDS are new to me, as is fiber channel, etc, up to now i relied on Synology for my server needs. Also I am not that familiar with Xserves so I don't know what the limitations are in terms of connectivity. The need: Additional Storage capacity for my mediaserver (currently Xserve 2.1). It should work with any other server in case I switch out the Xserve in the years to come. The Options as I see them: 1) NAS (e.g. Synology RS815 plus expansion), connected via ethernet (fyi: we have a 1000 BASE-T copper infrastructure at home) 2) External Raid (8-12 bays, rack-mountable) connected via: a) existing 2x FC-cards (Apple 2 Port 4Gbps FibreChannel card: pci1000,646) b) new FC-cards? c) new SATA cards? (does that even work? would it work with an Ubuntu running the server?) d) any other method of connection? I am clueless as to what way I should choose and which products I should buy for that. Or did I overlook a better solution? Thank you for your help, I appreciate it a lot! Best, Nick EDIT: Currently I run OS X Lion Server on it. Should I go for a more up-to-date OS, like Ubuntu? It will run on a stock-Xserve with minimal changes, I researched that. But will it run on a 'modded' Xserve (e.g. new connectivity via new FC or SATA PCI-E cards)?
