Enable Jumbo Frames for Independent Hardware iSCSI<br />
To enable Jumbo Frames for independent hardware iSCSI adapters in the <strong>vSphere</strong> Web Client, change the<br />
default value of the maximum transmission units (MTU) parameter.<br />
Use the Advanced Options settings to change the MTU parameter for the iSCSI HBA.<br />
Procedure<br />
1 Browse to the host in the <strong>vSphere</strong> Web Client navigator.<br />
2 Click the Manage tab, and click <strong>Storage</strong>.<br />
3 Click <strong>Storage</strong> Adapters, and select the independent hardware iSCSI adapter from the list of adapters.<br />
4 Under Adapter Details, click the Advanced Options tab and click Edit.<br />
5 Change the value of the MTU parameter.<br />
<strong>ESXi</strong> supports the MTU size up to 9000 Bytes.<br />
Configuring Discovery Addresses for iSCSI Adapters<br />
Set up target discovery addresses so that the iSCSI adapter can determine which storage resource on the<br />
network is available for access.<br />
The <strong>ESXi</strong> system supports these discovery methods:<br />
Dynamic Discovery Also known as SendTargets discovery. Each time the initiator contacts a<br />
specified iSCSI server, the initiator sends the SendTargets request to the server.<br />
The server responds by supplying a list of available targets to the initiator. The<br />
names and IP addresses of these targets appear on the Static Discovery tab. If<br />
you remove a static target added by dynamic discovery, the target might be<br />
returned to the list the next time a rescan happens, the HBA is reset, or the host<br />
is rebooted.<br />
Static Discovery The initiator does not have to perform any discovery. The initiator has a list of<br />
targets it can contact and uses their IP addresses and target names to<br />
communicate with them.<br />
Set Up Dynamic Discovery in the <strong>vSphere</strong> Client<br />
With Dynamic Discovery, each time the initiator contacts a specified iSCSI storage system, it sends the<br />
SendTargets request to the system. The iSCSI system responds by supplying a list of available targets to the<br />
initiator.<br />
Required privilege: Host.Configuration.<strong>Storage</strong> Partition Configuration<br />
When you set up Dynamic Discovery, you can only add a new iSCSI system. You cannot change the IP address,<br />
DNS name, or port number of an existing iSCSI system. To make changes, delete the existing system and add<br />
a new one.<br />
Procedure<br />
1 Log in to the <strong>vSphere</strong> Client, and select a host from the inventory panel.<br />
2 Click the Configuration tab, and click <strong>Storage</strong> Adapters in the Hardware panel.<br />
The list of available storage adapters appears.<br />
3 Click the Configuration tab, and click <strong>Storage</strong> Adapters in the Hardware panel.<br />
The list of available storage adapters appears.<br />
