Dell EMC Networking - Deploying VMware vSAN with OS10 Enterprise Edition | version 1.0
5.1.3.4 Enable Jumbo frames
This section provides steps to enable jumbo frames on the VDS and individual VMkernel adapters on each
host. Jumbo frames are recommended for vSAN and vMotion traffic and must be configured at the physical
switch, the VMkernel adapter, and the VDS. The following steps can be used to enable jumbo frames:
To enable jumbo frames at the VDS:
1. On the web client Home screen, select Networking.
2. Right click on the distributed switch and select and select Settings > Edit Settings.
3. Click on the Advanced settings page.
4. Change the MTU (Bytes) to 9000.
5. Click OK.
T
o enable jumbo frames on the VMkernel adapters:
1. On the web client Home screen, select Hosts and Clusters.
2. Click on the first host in the vSAN cluster.
3. In the center pane, select Configure > Networking > VMkernel adapters.
4. Click on the vSAN VMkernel adapter. Edit the VMkernel adapter by clicking on the Edit Settings icon.
5. Click on the NIC Settings page.
6. Change the MTU to 9000. Do not modify any other settings.
7. Click OK.
8. Repeat steps 4-7 for the vMotion VMkernel adapter on the same host.
9. Repeat steps 3-8 for all the remaining hosts in the vSAN cluster.
5.2 vSAN deployment
VMware vSAN virtualizes the local physical storage resources of ESXi hosts in a single cluster and uses them
to create pools of storage that can be divided and assigned to virtual machines and applications. VSAN is
implemented directly in the ESXi hypervisor. This section provides steps to enable vSAN on a cluster.
Note: The servers used in this example have 20 SSDs, all at the same capacity. The server hardware
configuration depends on the requirements and workload of the cluster. Administrators should consult
VMware guidelines and recommendations for vSAN clusters to assist in managing disk groups and devices.
For information on designing and sizing a vSAN cluster see VMware vSAN documentation. Within the
document Administering VMware vSAN, see the Designing and Sizing a vSAN Cluster section.
To configure a VSAN datastore on a cluster:
1. In the web client, go to Home > Hosts and Clusters.
2. In the Navigator pane, select the vSAN cluster.
3. In the center pane, select Configure > Settings > vSAN > General.
4. Click the Configure button to launch the Configure vSAN wizard.
a. On the vSAN capabilities page, leave all settings at their defaults. Click Next.
b. On the Network validation page, ensure all hosts show a vSAN enabled network. Click Next.
