Achieving 10Gbps Write-to-disk Performance (Part 3)

It’s been a very busy  few weeks. Today, I’m on the train headed for NYC so I have some spare time to make a blog entry.

This is a continuation of a short blog series about the four C’s of high-performance write-to-disk; namely: capture, controller, cores, and cache. Today it is about controller acceleration; specifically, RAID controller.

Design Rule #2:  Controller Acceleration

To support 10Gbps write-to-disk capture, a RAID configuration must be able to write ~1.25 GB/s at a sustained rate. On average, one can achieve between 75-100MB/s per drive, depending of the type of drive.
