Hope all is well, been a while, thats beacuse ive been busy and have had no issues so far with my current steup.
I am going to build a new PC system soon to take load of my main editing suite, and am looking to build a Media Server. The purpose of the media server would be to have this as my central data storage sytem with raid. And have 2x pc systems connected to the media server.
I have found this very interesting video on vimeo:
could I get some feedback please regarding this. and the parts they used. or advise on a similar setup.
A regular sandybridge CPU/motherboard/DDR3 RAM combo
1 x 8-port SAS RAID controller
2 x 24 port SAS expanders
1x 24 bay chassis with backplanes
2 x Infiniband cards
12 x 2TB Seagate HDDs
1 x Hardrigg case with 19" rails
1 x APC 3000 UPS
1 x 950w PSU
also i dont understand the 2x sas cards any ideas for this.
You will be able to use a server as a file repository, but from what I have read before (see below) PPro does not work to "directly" edit files on a server
Win Server is NOT supported http://forums.adobe.com/thread/851602

The SAS Expanders allow you to take 8 SAS channels that a standard SAS raid card supports and expand those to support far more devices. This is how you are able to daisy chain multiple SAS storage boxes to 1 SAS raid controller or multiple devices beyond 8 internally to a SAS raid controller. Oh and look at 10Gb Ethernet instead of Infiniband. The controllers are cheaper and cabling Cat 6A or Cat 7. Intel makes a Dual Port 10GBASE-T card that is cheap for 10Gb and you could run ISCSI to the server. The 10Gbit Ethernet switches should start coming down into the small business/consumer level next year. I heard rumors it would be this year but to many companies are still trying to get premium pricing/profit from Fiber to switch yet.
It can be done. We have two linux servers with a total of four ZFS raids and some large SSD drives for caching, connecting to 3 to 4 edit suites at a time via nfs, and edit fine off them via gigabit ethernet. All HD material; ProRes, h264, avchd, XDCAM HD422 etc. Each of our edit suites has an fast internal raid that to use as a scratch disc, but the media all stays on the server. There was a bit of trouble shooting to get it all set up right but everything all now works great.
10Gbit is 1.25GB of total bandwidth per channel. That is more than enough for any editing out right now. You can run with Quad Gbit cards which are cheaper and require less expensive switches then bridge them for load balancing. However the 10Gbit will be the standard used in the future when the price of 10Gbit Switches come down. Until then you could just direct connect the systems to the storage via a couple 10Gbit Ethernet cards. That is up to you. The only downside to editing over a network is latency on starting playback and scrubbing. You can offset some of that by using protocols that have less layers like ISCSI along with low latency switches.
