EDA500 Expansion chasis + RN312= combine volumes for XRAID2?
Hi everyone, I just got the 31200 (2-bay) and the EDA500 (5-bay) expansion chasis. I was hoping to add 7 disks and set up an XRAID2 volume. I just read some fine print that the eda500 will create a...

So in other words I am stuck with a 2 disk volume (1 disk used for mirror) and a 5 disk volume (one disk used for raid5)?
Yes.
Though there is capacity loss, it is more robust than trying to span the RAID volume across two chassis.
hi, thanks for the response, though it seems to be contradictory of this guys post:

is Kossboss wrong?
The way I am looking at it, a raid6 will provide better protection across all 7 disks. Especially in the case of a drive failure, and then an URE while the array is rebuilding.

I believe he was. With xraid, there should a second volume for the eda-500 called eda1. I'm not sure if you can set up a flexraid volume that spans the two chassis or not.

I agree.
Though if the cable disconnects with the systems running, the results might be unpredictable if you were to configure single volume. If power drops on the EDA but not on the RN312 you might run into trouble.
I am fooling around with it as we speak. It appears that with flexraid I can create a 7-disk volume that spans both chasis. I just need to confirm that there is ZERO way to do this with xraid.
