Theoretically max throughput of NetApp stack will be 9600 MB/sec. NetApp supports 240 HDDs per stack or 96 SSDs per stack. But it's not a system limit. You can have several stacks in one system. It depends on controllers model. SAS 6G one lane gives 600 MB/sec. But one SAS 6G port utilises 4 lanes. With NetApp you use 2 ports on each controller for one ...

That said if you aren't 100% sure you're 100% up to date then just do that on the next build, i.e. ...

Look at your SAS tape drive(s). Do you see one SAS port or two SAS ports? If you see one, you don't have any options to daisy-chain.

So it all comes down to the exact products you have, if you have a device that has both in and out ports then I say go for it - it won't be too hard to try and if it doesn't work you'll know about it pretty quickly. On a separate note I ...
