You haven't given us much description of how you expect to use these queues, so we can only give a general answer. First, check the datasheet for the part http://download.intel.com/design/network/datashts/82599_datasheet.pdf specifically looking at section 7.1.2.2 for Queuing in a Virtualized Environment. Note that you can set up the part for several different sizes of pools of queues, up to 64 pools of 2 queues each. Each of these pools can be given a different mac address filter. If you have RSS disabled, all packets will be given to the first queue in the pool and the second queue in each pool will be unused, effectively giving you only 64 receive queues. If you enable RSS you can use the second queue in each pool, giving you 128 receive queues. sln ------------------------------------------------------------------------------ Storage Efficiency Calculator This modeling tool is based on patent-pending intellectual property that has been used successfully in hundreds of IBM storage optimization engage- ments, worldwide.
