I have two application servers running in a active/active cluster within a VMWare ESXi (5.5, upgrade to 6.5 in near future) virtual host running VSphere. The application needs a shared, high performance storage.
ESXi utilizes an EMC storage using LUNs.
Is there a way to create an additional storage (disk device) that is mapped via VSphere to both VMs?
I personally would go with GlusterFS which introduces additional VMs, but my infrastructure administrators tend to reject it (VM limits reached). So the GlusterFS approach would not be possible for me.
