An administrator has four virtual guests on a host server. Two of the servers are corporate SQL servers, one is a corporate mail server, and one is a testing web server for a small group of…

Increasing virtual RAM allocation addresses memory resource constraints for I/O-intensive guests but does not resolve the administrator's network-level connectivity problem during peak usage.

Installing a separate management NIC and dedicated virtual switch creates an out-of-band management channel that is physically and logically isolated from the production network traffic generated by the virtual guests. This ensures that high network utilization from the SQL and mail servers cannot saturate the interface the administrator uses for host management, guaranteeing secure connectivity regardless of peak usage conditions. The separation also improves security posture by keeping management traffic on a network inaccessible to regular production traffic.

Switching from iSCSI to Fibre Channel over Ethernet may reduce storage network overhead but does not create a separate management network path unaffected by general peak IP traffic congestion.

Moving the guest web server to another host reduces workload on this server but does not guarantee administrator connectivity if the remaining high-I/O guests still saturate the single shared network interface.
