[casper] CASPER 10 GbE yellow block
Hi All, Using the latest 10 GbE yellow block, has anyone achieved a sustained data rate of greater than 8 Gb/s? Thanks, Rich
Re: [casper] CASPER 10 GbE yellow block
Hi, Rich, We've sustained 9.9 Gpbs simultaneously from two 10 GbE ports (19.8 Gbps aggregate) on a ROACH into a PC with two 10 GbE NICs without dropping any packets. This was direct connect (i.e. no switch) and transmit only (i.e. no packets were sent back to the ROACH). Hope this helps, Dave On Feb 13, 2013, at 1:06 PM, Rich Lacasse wrote: Hi All, Using the latest 10 GbE yellow block, has anyone achieved a sustained data rate of greater than 8 Gb/s? Thanks, Rich

Re: [casper] CASPER 10 GbE yellow block
Hi, John, The benchmarking tests were done here by Christopher Schollar who was visiting from the University of Cape Town. I'm not sure which library version he used, but I can find out. It was mostly just curiosity on my part, but are you using the same blocks for your work?

Re: [casper] CASPER 10 GbE yellow block
Hi, John, My current work is on ROACH2 and the 10_Gbe_v2 block is the only 10 GbE block supported on ROACH2 so that's the one I'm currently designing with (but not yet using myself). I'm not sure which block Christopher used in the packet generator. His design ran on a ROACH so it could have been using the ten_GbE or ten_Gbe_v2 block.

Re: [casper] CASPER 10 GbE yellow block
Hi Dave and others, I was under the impression that ten_Gbe_v2 was suppose to support ROACH2 as well. At least, its mask supports parameters specific to ROACH2 (such as choice between CX4, SFP+ and ports etc.). Rather, these options are available in the mask only for ROACH2. Is 10_Gbe_v2 part of SKA-SA github repository now and is that supposed to be used instead of ten_Gbe_v2? I have not updated the repository of late and have been using ten_Gbe_v2 for my ROACH2 design.

Re: [casper] CASPER 10 GbE yellow block
I think it's just a typo and ten_gbe_v2 == 10_gbe_v2 On Wed, Feb 13, 2013 at 5:47 PM, Nimish Sane nimishs...@gmail.com wrote: Hi Dave and others, I was under the impression that ten_Gbe_v2 was suppose to support ROACH2 as well.

Re: [casper] CASPER 10 GbE yellow block
Hi, Nimish, Sorry for my 10_Gbe_v2 typo. I meant ten_Gbe_v2. There is no 10_Gbe_v2 block. I am using the ten_Gbe_v2 block for ROACH2.

Re: [casper] CASPER 10 GbE yellow block
hi rich, we've transmitted 9.9 Gbit/sec on roach1, with the 10Gbe yellow block from the library about 4 months ago. i'm not sure if there have been revisions since then. best, dan On Wed, Feb 13, 2013 at 1:06 PM, Rich Lacasse rlaca...@nrao.edu wrote: Hi All, Using the latest 10 GbE yellow block, has anyone achieved a sustained data rate of greater than 8 Gb/s?
