    Lightbulb Hardware focus for HD Video website?

    We have a very high-definition (1080P) video intensive website (progressive download) on a dedicated server. We are looking to upgrade our hardware but don't know which pieces of the equation we should emphasize most. Our goal is to deliver the video to our visitors as quickly as possible. In other words, have them download it the fastest so it can start playing sooner in the browser.

    What part of the server hardware equation is most important for this? CPU, memory, HDD speed, etc? Thanks for your help.

    What's missing from your equation is your network, especially when you are concerned about download speed. You may want to look into using a content delivery network (CDN), such as Akamai or Limelight. Depending on your connection, many users downloading big files at the same time may actually end up depleting your bandwidth before your server reaches it's maximum capacity.

    Unless you plan on

    You will find that the issues will be on the viewers end - with the clients ISP connection; and quantity of concurrent viewers which will use hard drive and memory resources on the server.
    So, your emphasis should be placed on the hard drives (raid, disk speed, etc) and on increasing ram.
    We use SAS drives, RAID 10, 16 GB ram, and gige nics for our servers doing VOD.
    CPU usage is minimal.

    Good point. We did some stress testing on ours, they can do 2.4 gbps when using etherchannel bonding of four GigE nics. Would be able to handle 2,400 concurrent users. At that point the bottleneck is the hard drive.
