I need to build a server which is capable of capturing 20 Gigabit/second network traffic (2 x 10g network adapters - 99% utilization) and store them on a disk with zero packet-lose. The requirements is supply the ability to record 20-30 minutes of continues traffic.
Not being an “Hardware Expert”, I have search the net for today’s fastest hard drives and came up with the following option: Setting Raid-0 (stripe) over 6 x 600 GB WD’s VelociRaptor SATA drives, which claim to be the fastest (sata) drive on earth (6 Gb/s interface) - that would provide 36Gbps writing speed.
My questions are basically, having the hard drive spot sorted out,
- What about the other parts of the machine, what kind of a motherboard would I need?
- What kind of a CPU?
- How many CPUs?
- How much RAM is needed given the fact data is not manipulated but written into the hard drives?
I would like to thank you all in advance for your help and advises.
