You are designing a VMware HA platform based on vSphere converged network hardware– and
softwarebased iSCSI storage. Which of the following is true?
A.
vSphere 5 can provide protection for workloads in this design, using datastore heartbeats and
managementnetworks.
B.
vSphere 5 datastore heartbeats may not provide additional protection in this design if a physical
cardcontaining the management and storage networks fails.
Explanation:
VMware HA will check storage heartbeats or a lock file (NFS v3) on datastores in the event thatthe
management network is impacted. By using a CNA and slicing the 10 GB up into smaller chunks,
it couldbe 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 thiswould remove the extra protection the network storage heartbeats provide.
