Best architecture for 2 servers, 1 storage
I'm planning an architecture with two servers sharing a single storage. One server is primarily for mail and one is for file sharing. I'm considering using two Mac Mini's as the servers and Promise vTrak e30 as the storage.
I noticed the vTrak e30 has dual controllers with 4x8Gb FC each. Is it possible to connect the servers to the storage without an FC switch? Any downsides?
If using Xsan, do I need to have a third dedicated server setup as the metadata controller or can I assign one or both of the servers for that task (in addition to their main tasks)? Should the metadata traffic be separated from other IP traffic into a dedicated ethernet to get adequate performance?
