>From what I've read, the card would have to support PCI IOV and have separate DMA engines that are partitionable at the PCI-E fabric level. Then of course you need drivers to support such a device. Many NIC, FC HBA, and CNA card vendors are moving in that direction. So I would assume that perhaps within the next 2 years, it'll become a viable option. With the direction things are taking, it does make you wonder if it would make more sense for everything to go Infiniband at the server level and let the switches upstream split off to IP and FC. Would definitely take a lot of the complexity out of the equation and not to mention cabling.

Example, a quad nic card. >From what I've read, the granularity that can be assigned is a single card (of a limited selection of models supported for that functionality), not some subset of a card such as a single network or FC port. Presumably that has to do with the degree of isolation that can be obtained by using the point-to-point nature of PCIe. I have no idea whether the PCIe spec allows a multi-lane card that implements multiple (network or storage) ports to act like a group of single lane cards. If that were possible, it might provide a basis for what you describe, although it would presumably take driver as well as hardware support to make it happen. -- This message posted from opensolaris.org _______________________________________________ ldoms-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/ldoms-discuss _______________________________________________ ldoms-discuss mailing list [email protected] http://mail.opensolaris.org/mailman/listinfo/ldoms-discuss
