Home -> Community -> Mailing Lists -> Oracle-L -> Re: RAC Std: where to put 3rd voting disk with only 2 Storage Arrays
Hi
Normally for stretch clusters the 3rd voting disks is set in a third site using NFS, in your case you can probably set up a small server and place your third voting disk there
There is a WP on OTN about this setup.
Thanks
