A vSphere environment is configured with 1 Gigabit Ethernet for vSphere vMotion. The application team is complaining that when they try to migrate a poweredon virtual machine, the progress is slow and unsuccessful the majority of the time.
Which two recommendations should the administrator make to improve vSphere vMotion performance? (Choose two.)
A. Use at least two port groups.
B. Use vSphere Storage I/O Control (SIOC).
C. Use 10 Gigabit Ethernet or above.
D. Use Link Aggregation Control Protocol (LACP) on the port group.
E. Disable vSphere Fault Tolerance.
Not convinced by the answer
A and C are correct.
From the VMware vSphere: Install, Configure, Manage Lecture Manual ESXi 7 and vCenter Server 7 :
7-51 Host Requirements for vSphere vMotion Migration (2)
• At least a 1 Gigabit Ethernet (1 GigE) network:
— Each active vSphere vMotion process requires a minimum throughput of 250 Mbit/second on the vSphere vMotion network.
— Concurrent migrations are limited to four on a 1 Gbps network.
— Concurrent migrations are limited to eight on a 10 Gbps (or faster) network.
— For better performance, dedicate at least two port groups to the vSphere vMotion traffic.
