You are asked to help troubleshoot a virtual data center that is suffering from poor performance. There are 4 ESXi hosts running vSphere Enterprise Plus, each has dual 8 core Xeon processors, 48GB of RAM and each has 8 local drives configured in a RAID6 + Hot Spare array and 10/100Mbps NIC. Each hosts is running between 30-40 virtual machines. After monitoring the VM's, you can see all are running between 5-10% CPU utilization, have been assigned no more than 2GB of RAM each and using on average 1-2% of the NIC bandwidth. What is the likely cause of the performance problems?
The virtual machines do not have enough RAM allocated. Increase the
amount of RAM in each ESX/ESXi host using vMotion to migrate all VMs off the
host, upgrade it, and migrate them back.
The
local drive configuration is not ideal because a RAID6 + Hot Spare array is
only using 5 of the 8 available hard drives (1 as a spare and 2 for parity).
Storage should be adjusted to a more scalable SAN infrastructure.
The network infrastructure needs to be upgrade to at least 1Gbps NICs
and switches to support this number of virtual machines.
The virtual machines do not have enough RAM allocated. Increase the
amount of RAM in each ESX/ESX host using the hot add feature.
