iSCSI Acceleration with LACP

Thanks for visiting our forum and using Intel Ethernet.

The iSCSI Accleration mentioned in the Intel 82599 product brief: http://download.intel.com/design/network/prodbrf/321731.pdf, does work with LACP (

Link Aggregation Control Protocol).

We did a blog last year about iSCSI performance: http://communities.intel.com/community/wired/blog/2010/04/22/1-million-iops-how-about-125-million.  We also have another blog that explains how things were tuned for this test: http://communities.intel.com/community/wired/blog/2010/04/20/1-million-iop-article-explained

There are many articles on the web that detail tuning for different types of environments.  There really is no 1 setting for all to get optimal performance.  It really depends on many factors.

I forwarded your origianl question to some co-workers.  Here is the response - hope it helps.

The answer to your question about iSCSI acceleration working with LACP is yes, the iSCSI acceleration will still work with LACP.   However, if I read between the lines I suspect that you are really looking for the best way to combine your two 10GbE links to speed up your iSCSI transfers.  If that is the case, I would suggest that you not use LACP but rather IP Multipathing (IPMP http://www.oracle.com/technetwork/articles/systems-hardware-architecture/ha-rac-networking-ipmp-168440.pdf ).   The best source of information about configuring and tuning Solaris are of course the experts at Oracle.  I would suggest that you contact your Oracle support folks, visit Oracle’s Technology Network (where Big Admin used to live) at  http://www.oracle.com/technetwork/systems/index.html or search the web for Oracle whitepapers and blogs.  This link would be a good place to start http://www.oracle.com/technetwork/articles/systems-hardware-architecture/solaris-qs-tuning-163899.pdf
