I was using the updated driver package from broadcom, I tried around June Sign up using Email and Password. As my friend told “Intel NIC is usually the preference”. Several virtual machines were running on the iSCSI storage and the results were monitored. Post as a guest Name. Now, to use that specific interface to query my NAS, I simply specify the iface name on the iscsiadm commandline:

You have to “bind” the vmhba and the vmnic ports.

Whilst the information provided is correct to the best of my knowledge, I am not reponsible for any issues that may arise using this information, and you do so at your own risk.
(iSCSI) Configuring Broadcom 10 Gb iSCSI offload
Sign up using Email and Password. Does anybody have a clue about this? I tried to get the bnx2i working with dependant iscsi vmware config, but the bnx2i driver would actually crash and only some vmhba would show up.
In order to use this iface, we just apply the same IP address to the iface as is assigned to the physical interface. Anyone who has attempted to get iscsi offload working under RHEL5 can tell you… it can be a challenge. Additionally SAN HQ that comes with Dell EqualLogic provides additional confirmation and insight at the storage system level in regards to changes in perfomance.
It netxttreme really starting to get frustrating for me. The BACS2 utility also enables you to perform detailed tests, diagnostics, and broaddom on each adapter, as well as to modify property values and view traffic statistics for each adapter. You can follow any responses to this entry through the RSS 2.
So my advice is do not use the broadcom hardware dependant iSCSI initiator. Support for multicast addresses via bits hashing hardware function.
If you then inspect one of the newly discovered nodes, you should see the transport displayed thus:. The bnx2 driver is the networking driver; the bnx2i is the iSCSI offload driver; and the cnic driver is the ‘broker’ that supports the features required by the bnx2i iSCSI offload driver. That permanently adds the specified IP address to the iscsi interface.

I hope this helps. The adapter driver intelligently adjusts host interrupt frequency broadom on traffic conditions to increase overall application throughput. Therefore, the adapter’s iSCSI offload architecture is unique as evident by the split between hardware and host processing.

Well, Helvick’s answer is right. When traffic is light, the adapter driver interrupts the host for each received packet, minimizing latency. Broadcom Advanced Control Suite 2 also provides information about the status of the network link and activity see Vital Sign.
Using the Broadcom teaming software, you can split your network into virtual LANs VLANs as well as group multiple network adapters together into teams to provide network load balancing and fault tolerance functionality.
