Hello ,

I am Sabeer , working for Renault Nissan in India.

I have a query

What will be the usable space of DS4243 24 drives of 600gb SAS DISKS provided if we go for double parity.


Re: DS

Hi Sabeer

Is this a single controller system or dual?

How would you like to assign the drives to controllers (in numbers. eg: 12-12)? as minimum 3 drives is necessary to make controller up.

Re: DS

If it's a dual controller system you will get approx 6.7TB usable space creating 2 aggregates (1 on each controller) with 12 drives each. and 20% snapshot reserve. (calculations: 18 data drives 4 parity and 2 spare)
