An administrator is deploying an application using Nutanix Volumes. After configuring the volume group and connecting the guest's iSCSI initiator to the volume group, they begin performance testing. The administrator learns that performance on the virtual disk attached to the iSCSI initiator is far less than that of a virtual disk connected directly to the VM.
Which situation is causing this condition?
The cause of the performance degradation is that the VM's iSCSI traffic is being routed to the data services IP subnet. The routing process adds overhead and potentially introduces delays, which is why the performance is significantly lower compared to a virtual disk connected directly to the VM. This scenario is common when the network design causes traffic to traverse additional network segments or routers, impacting overall throughput and latency.
A. is correct C. iSCSI Data Services IP enables path optimization in the cluster, preventing bottlenecks
If the guest VM doesn't have an interface on the iSCSI network, the traffic will have to pass from the guest VM network, through a router, and then to the iSCSI network. I believe the answer is A.
"far less"，So the answer C is more suitable
iSCSI would be routed due to different vlans, resulting in longer times.
