You can measure this yourself. Try running the test both with and without the "sync" command at the end. You should see a faster completion time without the "sync", but not all data will have made it to storage. How long the "sync" might take will depend on how much RAM the ZFS ARC is using, which in turn can depend on how much RAM the system has, among other things. > - can you send me the guide that tell to change the sd_max_throttle to 32 on > solaris10 or solaris8? there would me no more then 30 LUN active on the port > but no simultanies. I cannot send it to you. You can find it on the documentation CD that came with your array; Your HDS service person can also get it for you. It should have "Installation Guide for Solaris" in the document title. Most of the references from Sun on this topic appear to be available only to contract support customers.

It can use both ports at the same time.
