vSphere Storage n To set up and verify physical network switches for Jumbo Frames, consult your vendor documentation. The following table explains the level of support that ESXi provides to Jumbo Frames. Table 11-3. Support of Jumbo Frames Type of iSCSI Adapters Jumbo Frames Support Software iSCSI Supported Dependent Hardware iSCSI Supported. Check with vendor. Independent Hardware iSCSI Supported. Check with vendor. Enable Jumbo Frames for iSCSI Use the vSphere Client to enable Jumbo Frames for each vSphere standard switch and VMkernel adapter designated for iSCSI traffic. Enable Jumbo Frames on the Standard switch and VMkernel adapter by changing the maximum transmission units (MTU) parameter. Procedure 1 Log in to the vSphere Client, and select a host from the inventory panel. 2 Click the Configuration tab and click Networking. 3 Click Properties for the standard switch you use for iSCSI traffic. 4 On the Ports tab, select the standard switch and click Edit. 5 Set the MTU parameter for the standard switch, and click OK. This step sets the MTU for all physical NICs on that standard switch. The MTU value should be set to the largest MTU size among all NICs connected to the standard switch. 6 On the Ports tab, select the VMkernel adapter and click Edit. 7 Set the MTU to match the value configured on the standard switch, and click OK. Enable Jumbo Frames for Software and Dependent Hardware iSCSI To enable Jumbo Frames for software and dependent hardware iSCSI adapters in the vSphere Web Client, change the default value of the maximum transmission units (MTU) parameter. You change the MTU parameter on the vSphere switch that you use for iSCSI traffic. For more information, see the vSphere Networking documentation. Procedure 1 Browse to the host in the vSphere Web Client navigator. 2 Click the Manage tab, and click Networking. 3 Click Virtual Switches, and select the vSphere switch that you want to modify from the list. 4 Click the Edit Settings icon. 5 On the Properties page, change the MTU parameter. This step sets the MTU for all physical NICs on that standard switch. The MTU value should be set to the largest MTU size among all NICs connected to the standard switch. ESXi supports the MTU size up to 9000 Bytes. 98 VMware, Inc.
Enable Jumbo Frames for Independent Hardware iSCSI To enable Jumbo Frames for independent hardware iSCSI adapters in the vSphere Web Client, change the default value of the maximum transmission units (MTU) parameter. Use the Advanced Options settings to change the MTU parameter for the iSCSI HBA. Procedure 1 Browse to the host in the vSphere Web Client navigator. 2 Click the Manage tab, and click Storage. 3 Click Storage Adapters, and select the independent hardware iSCSI adapter from the list of adapters. 4 Under Adapter Details, click the Advanced Options tab and click Edit. 5 Change the value of the MTU parameter. ESXi supports the MTU size up to 9000 Bytes. Configuring Discovery Addresses for iSCSI Adapters Set up target discovery addresses so that the iSCSI adapter can determine which storage resource on the network is available for access. The ESXi system supports these discovery methods: Dynamic Discovery Also known as SendTargets discovery. Each time the initiator contacts a specified iSCSI server, the initiator sends the SendTargets request to the server. The server responds by supplying a list of available targets to the initiator. The names and IP addresses of these targets appear on the Static Discovery tab. If you remove a static target added by dynamic discovery, the target might be returned to the list the next time a rescan happens, the HBA is reset, or the host is rebooted. Static Discovery The initiator does not have to perform any discovery. The initiator has a list of targets it can contact and uses their IP addresses and target names to communicate with them. Set Up Dynamic Discovery in the vSphere Client With Dynamic Discovery, each time the initiator contacts a specified iSCSI storage system, it sends the SendTargets request to the system. The iSCSI system responds by supplying a list of available targets to the initiator. Required privilege: Host.Configuration.Storage Partition Configuration When you set up Dynamic Discovery, you can only add a new iSCSI system. You cannot change the IP address, DNS name, or port number of an existing iSCSI system. To make changes, delete the existing system and add a new one. Procedure 1 Log in to the vSphere Client, and select a host from the inventory panel. 2 Click the Configuration tab, and click Storage Adapters in the Hardware panel. The list of available storage adapters appears. 3 Click the Configuration tab, and click Storage Adapters in the Hardware panel. The list of available storage adapters appears.
