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.
Hi Patrick,
Can you give me some example of tunning parameter value for best performance iSCSI of files traffic?
Best regards,
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
