Hi every body

We have two fas3220 single controller chassis and two DS4243 and two ds2246,

the fas3220 do not option any additional sas adapter,

and I want it be a dual chassis HA,

so I will connection the sas cable just like this

Is that right or wrong ?

Thanks

if I remember correctly, this is now allowed. but only with ONE transition between IOM3 and IOM6.

but there is a mistake in your cabling on the right head: switch those ports.

a and c ports connect always to the square port, while b and d ports connect to the round.
