Question

You are designing a VMware HA platform based on vSphere converged network hardware?and softwarebased iSCSI storage. Which of the following is true?

Options

AvSphere 5 can provide protection for workloads in this design, using datastore heartbeats and management
BvSphere 5 datastore heartbeats may not provide additional protection in this design if a physical card

Explanation

VMware HA will check storage heartbeats or a lock file (NFS v3) on datastores in the event that the management network is impacted. By using a CNA and slicing the 10 GB up into smaller chunks, it could be possible perspective to have a smaller number of physical NICs but with multiple logical networks defined. As a CNA can define network and storage configuration, it could be a major outage if the NIC failed, and this would remove the extra protection the network storage heartbeats provide.
