But where does one get SR-IOV devices to experiment with? It looks like the Intel 82576 chipset has SR-IOV, and can be had in a $50 card, two ports, 8 filters per port. The Intel 82599 is a 10Gb chip with more filters per port. (with linux support for the SR-IOV, it can manifest as multiple devices)
Disk storage is less obvious. The LSI 2308 and 3008 controller chips probably support it, but I'm not finding a commodity card or a motherboard integrating one.
They mention in the paper that existing devices have problems which prevent them from actually securely isolating clients of the sub devices. Combine this with seeing a lot of web activity about SR-IOV in 2009 and not much now. Either it became too common to mention, or is dwindling into an idea that didn't catch on. The wait for secure SR-IOV might be interminable.
- nkurz 12y agoIn the paper, they say they are using "an Intel MegaRAID RS3DC040 RAID controller with 1GB cache of flash-backed DRAM, exposing a 100GB Intel DC S3700 series SSD as one logical disk". I'm not familiar with it, but is that raid controller insufficiently commodity? Edit: I see now it's around $500. This list of cards and motherboards using the LSI 2308 and 3008 might be a starting point for finding something less expensive: http://forums.servethehome.com/index.php?threads/lsi-raid-controller-and-hba-complete-listing-plus-oem-models.599/ http://forums.servethehome.com/index.php?threads/lsi-raid-co...
