Routing Enormous Traffic for Video Studio #2
Hi, --- Sorry, small addition to post #1 Anyone had and experience (or just ideas) how to use Linux server in video studio for sharing RAID between 3 - 4 Power Mac workstations, taking into account enormous traffic generated by video capture and editing? One solution is to use Apple XRaid, XSan, and 2 XServe (1 pc will work, but 2 pcs are better, one is used for routing traffic, second for data transfer). Unfortunately, this is OUT of budget (Fibre Channel SAN system is not a solution for a project with strict budget). My idea is to use 3Ware Escalade Card (with 8x500 GB HDs formatted as 4 Level-0 RAIDs), installed into Linux box, and 4-port Gigabit Ethernet Card. The question is how to organize traffic routing between this Linux box and 4 PowerMacs (all of them have Gigabit Ethernet on-board), so each Mac could see every RAID, yet passing exclusively all traffic through defined Ethernet port on server (in order to avoid Ethernet link saturation and video frame dropout)? Additionally, all Macs should see each other. Of course, its possible to connect each Mac to own Ethernet port on Linux box, but in this case Macs will NOT see each other! Phew, complex and unusual, but that is a challenge :-)) Thanks in advance for any suggestion(s). ************************************************ *** with best regards *** Andrei Verovski (aka MacGuru) *** Mac, Linux, DTP, Programming Web Site *** *** http://snow.prohosting.com/guru4mac/ ************************************************

I have a system somewhat like this. Tyan dual Xeon, dual 3ware 9000 cards, 16 disks, multiple dual-port nics (cheaper per port than a quad, & cheaper spare). BTW don't forget another NIC to the Internet/office LAN if the mobo doesn't have one. You can buy boxes like this preconfigured if you wish - I did.

This is best if you can do it (i.e. if you control the cabling)
but in this case Macs will NOT see each other!
Yes they will if you enable your server to do routing (Yast/Network services/Routing)
Phew, complex and unusual, but that is a challenge :-))

As somebody else said, you'll need to be careful about network protocols etc to achieve full performance. Cheers, Dave
