shared storage between 2 nodes within a cluster over common SAS disk

Hi, I'm wondering how to use a DELL ME5024 attached via SAS cards to two members of a PROXMOX VE cluster. The idea is to offer a direct access to the VM disks to the 2 nodes and to reduce the migration time when one of the nodes fells down. Any help would be appreciate.
My cluster is in version 7.3-4
