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 (
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.
