DS4243 single-path cabling

IGORSTOJNOV

Hello,

I'm trying to find out whether it's possible to do single-path cabling for two DS4243 shelves on FAS3240, more precisely, if I can utilize 2 free SAS ports on an expansion card to create a separate, non-resilient, single-path stack...

I've consulted "Universal SAS and ACP Cabling Guide" (https://library.netapp.com/ecm/ecm_get_file/ECMM1280392) but it only covers single-head FAS22xx setups - probably on account of limited expansion slots - but I'm wondering if it's possible on other models as well?

Regards,

Igor

Why would you want to do that.. You're ultimate goal would be MPHA

+1 not recommended... is it that you have all ports used and not enough available for MPHA? Can you add a SAS HBA if that is the case?

Yes, I'm aware it's not recommended. But let's say previous stack has hit it's shelf count limit, there's no more room for expansion cards, I've only 2 SAS ports remaining and 2 used shelves at my disposal for holding (truly non-critical) data. It wouldn't be resilient but it would still be additional capacity.
