vSphere Storage After you configure the dependent hardware iSCSI adapter, the discovery and authentication data are passed through the network connection, while the iSCSI traffic goes through the iSCSI engine, bypassing the network. The entire setup and configuration process for the dependent hardware iSCSI adapters involves these steps: 1 View the dependent hardware adapters. n To view in the vSphere Client, see “View Dependent Hardware iSCSI Adapters,” on page 83. n To view in the vSphere Web Client, see “View Dependent Hardware iSCSI Adapters in the vSphere Web Client,” on page 83. If your dependent hardware adapters do not appear on the list of storage adapters, check whether they need to be licensed. See your vendor documentation. 2 Determine the association between the dependent hardware adapters and physical NICs. n For the vSphere Client, see “Determine Association Between iSCSI and Network Adapters,” on page 84. n For the vSphere Web Client, see “Determine Association Between iSCSI and Network Adapters in the vSphere Web Client,” on page 84. Make sure to note the names of the corresponding physical NICs. For example, the vmhba33 adapter corresponds to vmnic1 and vmhba34 corresponds to vmnic2. 3 Configure networking for iSCSI. See “Setting Up iSCSI Network,” on page 87. Configuring the network involves creating a VMkernel interface for each physical network adapter and associating the interface with an appropriate iSCSI adapter. 4 (Optional) Enable Jumbo Frames. See “Using Jumbo Frames with iSCSI,” on page 97. 5 Configure discovery information. See “Configuring Discovery Addresses for iSCSI Adapters,” on page 99. 6 (Optional) Configure CHAP parameters. See “Configuring CHAP Parameters for iSCSI Adapters,” on page 102. Dependent Hardware iSCSI Considerations When you use dependent hardware iSCSI adapters with ESXi, certain considerations apply. n When you use any dependent hardware iSCSI adapter, performance reporting for a NIC associated with the adapter might show little or no activity, even when iSCSI traffic is heavy. This behavior occurs because the iSCSI traffic bypasses the regular networking stack. n If you use a third-party virtual switch, for example Cisco Nexus 1000V DVS, disable automatic pinning. Use manual pinning instead, making sure to connect a VMkernel adapter (vmk) to an appropriate physical NIC (vmnic). For information, refer to your virtual switch vendor documentation. n The Broadcom iSCSI adapter performs data reassembly in hardware, which has a limited buffer space. When you use the Broadcom iSCSI adapter in a congested network or under heavy load, enable flow control to avoid performance degradation. Flow control manages the rate of data transmission between two nodes to prevent a fast sender from overrunning a slow receiver. For best results, enable flow control at the end points of the I/O path, at the hosts and iSCSI storage systems. To enable flow control for the host, use the esxcli system module parameters command. For details, see the VMware knowledge base article at http://kb.vmware.com/kb/1013413 82 VMware, Inc.
n Broadcom iSCSI adapters do not support IPv6. View Dependent Hardware iSCSI Adapters View a dependent hardware iSCSI adapter to verify that it is correctly loaded. If the dependent hardware adapter does not appear on the list of storage adapters, check whether it needs to be licensed. See your vendor documentation. Prerequisites Required privilege: Host.Configuration.Storage Partition Configuration 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. If it is installed, the dependent hardware iSCSI adapter appears on the list of storage adapters under such category as, for example, Broadcom iSCSI Adapter. 3 Select the adapter to view and click Properties. The iSCSI Initiator Properties dialog box opens. It displays the default details for the adapter, including the iSCSI name, iSCSI alias, and the status. 4 (Optional) To change the default iSCSI name, click Configure. What to do next Although the dependent iSCSI adapter is enabled by default, to make it functional, you must set up networking for the iSCSI traffic and bind the adapter to the appropriate VMkernel iSCSI port. You then configure discovery addresses and CHAP parameters. View Dependent Hardware iSCSI Adapters in the vSphere Web Client View a dependent hardware iSCSI adapter to verify that it is correctly loaded. If installed, the dependent hardware iSCSI adapter (vmhba#) appears on the list of storage adapters under such category as, for example, Broadcom iSCSI Adapter. If the dependent hardware adapter does not appear on the list of storage adapters, check whether it needs to be licensed. See your vendor documentation. Procedure 1 Browse to the host in the vSphere Web Client navigator. 2 Click the Manage tab, and click Storage. 3 Click Storage Adapters. 4 Select the adapter (vmhba#) to view. The default details for the adapter appear, including the iSCSI name, iSCSI alias, and the status. What to do next Chapter 11 Configuring iSCSI Adapters and Storage Although the dependent iSCSI adapter is enabled by default, to make it functional, you must set up networking for the iSCSI traffic and bind the adapter to the appropriate VMkernel iSCSI port. You then configure discovery addresses and CHAP parameters. VMware, Inc. 83
