Chapter 3 Installation
Improving Performance on the ESX and VM
Step 2
You have completed this procedure.
Improving Performance on the ESX and VM
Use the following pointers to improve performance on the ESX host and the VMs.
• Install VMware Tools on the vCenter Server VM, with Hardware Acceleration enabled.
•
Use the command line interface in the VMs instead of the graphical interface where possible.
Verifying the Domain Configuration
The Virtual Supervisor Module (VSM) and Virtual Ethernet Module (VEM) are separated within a Layer
2 domain. To allow VSM-VEM pairs to communicate within the same Layer 2 domain, each pair must
have a unique identifier. The domain ID serves as the unique identifier that allows multiple VSM-VEM
pairs to communicate inside the same Layer 2 domain.
Following the installation of the Cisco Nexus 1000V, make certain that you configure a domain ID.
Without a domain ID, the VSM cannot connect to the vCenter Server. Follow these guidelines:
•
The domain ID should be a value within the range of 1 to 4095.
• All the control traffic between the VSM and the VEM is carried over the configured control VLAN.
•
All the data traffic between the VSM and the VEM is carried over the configured packet VLAN.
• Make sure that the control VLAN and the packet VLAN are allowed on the port in the upstream
switch to which the physical NIC of the host hosting the VSM and VEM VM are connected.
Verifying the Port Group Assignments for a VSM VM Virtual
Interface
You can verify that two port groups are created on the ESX hosting the VSM VM through the vCenter
Server. The following port groups (PG) should be created:
• Control PG (Vlan = Control VLAN)
•
Packet PG (Vlan = Packet VLAN)
• Management PG (Vlan = Management VLAN)
Make sure the port groups are assigned to the three virtual interfaces of the VSM VM in the following
order:
Virtual Interface Number Port Group
Network Adapter 1 Control PG
Network Adapter 2 MGMT PG
Network Adapter 3 Packet PG
