The Marvell 8059 Gigabit controller of my motherboard does unfortunately not have any drivers for OpenSolaris:
http://opensolaris.org/jive/thread.jspa?messageID=498048 I am therefore looking for a PCI-E Gigabit Ethernet Dual Port NIC with low latency (usable for latency sensitive apps), a stable, well performing and feature complete driver for OpenSolaris/OpenIndiana. I am trying to make an informed decision between: ProductCode: EXPI9402PT/EXPI9402PTBLK BrandName: Intel PRO/1000 PT Dual Port Server Adapter Chipset: 82571GB IntelGeneration: Fifth ProductBrief: http://www.intel.com/Assets/PDF/prodbrief/pro1000_pt_dualport_server_adapter.pdf Driver: e1000g ProductCode: E1G42ET BrandName: Intel Gigabit ET Dual Port Server Adapter Chipset: 82576 IntelGeneration: Third ProductBrief: http://www.intel.com/Assets/PDF/prodbrief/320116.pdf Driver: igb According to the Intel Ethernet Adapter Overview: http://download.intel.com/network/connectivity/products/prodbrf/252454.pdf the ET card provides 3 features the PT is lacking: IPsec, VMDq, SR-IOV. Do OpenSolaris drivers support these features or is support for them being worked on? On the other hand the PT card is described as "Fifth generation of Intel network adapters for Gigabit Ethernet" whereas the ET as "Intels third generation of PCIe GbE network adapters". Are these just marketing gimmicks or does the "fifth generation" provide any real technical advantages? Are there currently any bugs in the e1000g and igb drivers related to these adapters? (there have been complaints about connection losses / driver hangs) I have read claims that the igb drivers implement much of the functionality in software and therefore burden the CPU and perform worse than e1000g that are supposedly leveraging the hardware much better. Is there any truth to this? Can you please share your recommendations and experiences with these adapters and their drivers on Opensolaris/Solaris/OpenIndiana/Illumos? Recommendations of any alternate Dual Port Gigabit Adapters are welcome as well. Thanks. =Dusan -- This message posted from opensolaris.org _______________________________________________ opensolaris-discuss mailing list opensolaris-discuss@opensolaris.org
