Is that 12Gbps each way meaning 24Gbps or one way?

Lunux backup server would have to have enough CPU to process all that traffic. All, So here is the answer, the SAS back plane is basically just a huge bus architecture.

That’s 15 disks per shelf and a total of 45 disks in a three shelf configuration. I know what the theoretical max is simply based on the fact that the server has a single 12g conection de,l array of shelves. Join our community today!
