Note that it is recommended for the TCOSS file structure to be allocated on a separate VMFS volume (in
order to minimize contention with the other VMs).
5.3.4 Network
Similar to the disk resources, there is no possibility to allocate required network bandwidth for a particular
VM.
On the ESX host there is only a possibility to configure so called network traffic shaping, that performs the
opposite, i.e., limits network bandwidth at the virtual switch level:
But the experience from the real world shows, that network bandwidth is not a significant factor in ESX
server performance since the most large-scale hosts are provided gigabit network connectivity.
Furthermore, also CPU utilization plays a significant role in reaching acceptable network throughput,
especially in virtualized environments, where significant part of network connectivity is realized in the
software (virtual switches, etc.). Insufficient CPU resources will reduce maximum network throughput and
therefore it is important to:
1. Monitor CPU utilization on the ESX host permanently
