As my friend told “Intel NIC is usually the preference”. If you then inspect one of the newly discovered nodes, you should see the transport displayed thus:. So, an example iface name would be bnx2i. Broadcom NIC has compatibility issue with Esxi 4. The adapter driver intelligently adjusts host interrupt frequency based on traffic conditions to increase overall application throughput.

iSCSI Offload on RHEL6
Iii SAN HQ that comes with Dell EqualLogic provides additional confirmation and insight at the storage system level in regards to changes in perfomance. In the below performance graphs it is clear to see that as soon as the switch from software initiator with jumbo frames to hardware initiator without jumbo frames is made, the difference is betxtreme Magnus Andersson 21 2.
The Broadcom Netxtreme II adapter has software support for the following operating systems:.
[CentOS] iSCSI offload with Broadcom NetXtreme II BCM
It can be only used as software iSCSI initiator. I hope this helps. Well, Helvick’s answer is right.
You should then see it find one copy of every node for each iface we used to do the query. The TOE support on the adapter significantly reduces the host CPU utilization while preserving the implementation of the operating system stack. Whilst the information provided is correct to the best of my knowledge, I am not offlozd for any issues that may arise using this netxgreme, and you do so at your own risk.
Most of the machines we use are HP Proliant models of one flavor or another. Role of iscsi offload driver bnx2i Ask Question. Home Questions Tags Users Unanswered. As my friend told “Intel NIC is usually the preference”.
[CentOS] iSCSI offload with Broadcom NetXtreme II BCM5709.
In order to use this iface, we just apply the same IP address to the iface as is assigned to the physical interface. They make a good choice, as they have good performance, and are significantly cheaper than a full hardware iSCSI initiator like a QLogic C. WOL is not supported on blade servers. If you then inspect one of the newly discovered nodes, you should see the transport displayed thus:. Broadcom Advanced Control Suite 2 diagnostic and configuration software suite.
The C-NIC offers acceleration for all popular lffload used in the data center, such as:. Are these drivers necessary for supporting bnx2i? I am using open-iscsi initiator and using bnx2i broadcom offload driver However, there are many related drivers – bnx2, bnx2x and cnic drivers available.
You can leave a responseor trackback from your own site.
Now, to use that specific interface to query my NAS, I simply specify the iface name on the iscsiadm commandline:. Sign up using Email and Password. Anyone who has attempted to get iscsi offload working under RHEL5 can tell you… it can be a challenge. So my advice is do not use the broadcom hardware dependant iSCSI initiator.
The adapter driver intelligently adjusts host interrupt frequency based on traffic conditions to increase overall application throughput.
