10GB ethernet , iSCSI, Fibre, and LACP where to begin....

I'm venturing into a new word of networking. I have a small video company that handles occasional 200 MB/s data streams to 1-5 workstations at any given time. The data is stored on a External HD connected to a server.

I'm considering LACP (trunk 2x1GB connections to the server) to beef up the connections while being staying cost effective and maintaining current copper lines. Does anyone have any other routes for high bandwidth connections?  I've been researching 10GB ethernet, iscsi, fibre as well as LACP...

I suppose my question is: Does anyone have a website or online resource that discusses the pros and cons of each type of set up?

A single cable attached to one of the ports provides two channels of up to 10Gb/s in both directions.

Before you look at network performance I would measure just how fast you can copy data to/from that external hard disk of yours. An easy test would be to copy one of your video files from the external disk to your main disk in the server, if that doesn't exceed 100MB/s then any bandwidth over 1Gb is wasted.

You can't use iSCSI by the way, it's a block level protocol so cannot be used for file sharing, not that it matters since it's the underlying medium (ethernet in most cases) that you're looking at.

You may want to consider copying the data to your local hard drive, or in future consider the use of USB 3 hard drives, Firewire, or the upcoming Thunderbolt

If you have your server connected at 1Gbps I wouldn't bother doing any more unless you move the storage from the External HDD.  If the HDD is USB2 you will only be able to transfer files at a maximum of 480Mbps - and that's on a good day!

You only need to explore 10Gbps and iSCSI if you move your storage to a SAN, and that can get really expensive.
The company Drobo makes a few cost effective storage units that can connect to a network or directly to a server/workstation.
