In a 24 node Stretched Cluster VxRail deployment, what is the acceptable Rout Trip Time (RTT) latency between sites?
A . Primary to witness site RTT latency: 10 msSecondary to witness site RTT latency: 10 msPrimary tosecondary site RTT latency: 10 ms
B . Primary to witness site RTT latency: 50 msSecondary to witness site RTT latency: 50 msPrimary to secondary site RTT latency: 6 ms
C . Primary to witness site RTT latency: 75 msSecondary to witness site RTT latency: 75 msPrimary to secondary site RTT latency: 1 ms
D . Primary to witness site RTT latency: 75 msSecondary to witness site RTT latency: 150 msPrimary to secondary site RTT latency: 5 ms
Answer: A
Explanation:
Referencehttps://www.emc.com/collateral/white-papers/h15275-vxrail-planning-guide-virtual-san-stretched-cluster.pdf(page 6)
In most vSAN Stretched Cluster configurations, latency or RTT (Round Trip Time) between sites hosting VM objects
and the witness nodes should not be greater than 200msec (100msec one-way).
