You are all right 🙂 VidSharX can run on, say a MacBook Pro, wich is also running Media Composer. That MacBook can then connect with ethernet to another Mac (MacBook or other) wich is also running Media Composer. BUT, you will need, as Bob points out, a fast drive for the media and projects.
My test setup for the smallest, most portable configuration is (was, since I poured a Caffe Latte into one of them…) two MacBook Airs with no external drive, just using a separate partition on the internal SSD drive on the MacBook that acted as a server. Then, a thunderbolt to ethernet adaptor in each of the Macbooks and a short ethernet cable (no switch!)
That would handle DV25 media without problem, and also DNXHD36. Obviously, very limited in space, but for a short, fast project, it would suffice.
But, again, these are the limiting factors in any system, in order of how I have experienced it.
Number one: Drives! Ethernet is fine for many resolutions, and you will never get much over 60 MB/s over ethernet and samba (1Gigabit, not 10Gbit). But as you connect more clients (editors) the speed on the drives drops quite fast. So my rule of thumb, used to be – one drive for each client. So in a raid configuration, 5 drives in RAID5 would support 5 editors. This is very unscientific, but worked quite well for us.. But we work mostly in low resolutions, IMX50 or DNXHD36.
The bottomline is, you will probably sooner run out of speed on the raid than on the network…
2. Bandwidth FROM the server TO the switch. The clients are usually fine with 1Gbit from the switch, but you want to link aggregate (AKA trunk or bond) the ports from the server, or run 10Gbit to the switch. This means combining the ports on the MacPro to get 2Gbit or installing a separate ethernet port interface card from for example Small Tree, to get 4 or 6 ports in a bond to the switch, for 4GBit or 6Gbit to the switch.
Then of course a lot of things have effect, using CAT6 instead of CAT5 cables, the RAM on the server, processor speed etc.
VidSharX is for you if you have a bit of knowledge about these things and some time to set it up. If you do, you can save some money. If you have a lot of money, as usual, go shopping!
all the best
