P800 + two msa50's

Is it possible to connect two msa50 storage boxes to a p800 controller and setup raid 1+0 mirroring over the two msa's.
So if one msa50 dies the disk will still be available.

Re: P800 + two msa50's

There is a way to get the redundancey between MSA50s. To achieve this we need to cascade the 2 MSA50 boxes and should be connected to single controller port. If you connect 2 MSA boxes to different ports on the controllers then we can't perfom array creation by using both MSA50s. each array has to manage seperately.

But i hope you can achieve redundancy even if connect to different ports on P800 subjected to you need to use software based mirroring.

Re: P800 + two msa50's

But if you cascade the msa50's wouldn't the first box be your single point of failure?
So there is no way to setup a hardware raid between the two MSA's when you connect them to separate ports on the p800?
I don't like the idea of using software raid.
