That link was for 5m - the 0.5m & 1m is like $18. fs.com shipping is ~ $12, so more like $30 in total$40 is a lot more than $15 but might be worth it not to have 5m of cable coiled in my rack.
If you have a hypervisor, it's great. For instance in ESXi, you should see lower CPU utilization with 10GbE or 40 GbE network cards, that's because you're really doing offloads. With non SR-IOV, the "offload" is handled by the VMXNET3 driver - you're using host CPU cycles in the end.Gotcha.
How important is SR-IOV? I've been running ConnectX-2 cards for the last few years for 10G, if that impacts anything.
Better stay in 8.0.80 train, it's more stable.Not sure if this is of interest to anyone else but I managed to upgrade from 8.0.80e to 8.0.90d on my ICX-7250-24 tonight. Here's what I did:
I registered on Ruckus' website and downloaded the latest zip for the ICX-7250. After that I extracted the zip and tftp'd over the spz10115.bin boot-loader. I then tftpd'd over the SPR08090d.bin firmware and reloaded the switch. It took a little longer than usual to come up after the reload. Per the manual I then tftpd'd over the SPR08090dufi.bin firmware. This took substantially longer, ~7 minutes to come back after a reload. From what I can gather it appears everything upgraded successfully and I am not missing functionality, but I am by no means anywhere near an expert with networking gear.
Yeah the RPS15-I is supposed to be non POE and Intake (so air flow is from back to front) https://www.commscope.com/globalassets/digizuite/61732-ds-icx-7650.pdfI just noticed something on the switch I bought. The PSU is labeled at 250w. RPS15-I. Did I get suckered into bidding on a Poe switch sold with the non-poe PSUs?
@WANg had a similar issue while on ESXi 6.0u3: https://forums.servethehome.com/ind...orking-correctly-in-esxi-6-0u3-patch-22.28492ESXi 6.7 and 7.0 dropped support for CX-3 SR-IOV. There's other OSes where it works fine
6.7 yes, 7.0 no. 7.0 does not have the VMKLinux support at all, while 6.7 is not enabled unless you specifically disable the native driver and enable the VMKLinux driver. It’s not like the card doesn’t work on the native driver - it just doesn’t give you SRIOV.@WANg had a similar issue while on ESXi 6.0u3: https://forums.servethehome.com/ind...orking-correctly-in-esxi-6-0u3-patch-22.28492
But he wanted to upgrade to the latest OFED driver bundle. I wonder if the older driver in 6.5 could be used in 6.7/7.0? I'm still on 6.5.
Could you share port and initiator/target configurations for RDMA?The 6610 works fine with RDMA/iSER, without any DCB/PFC support, even up to 40gbps.
I dismantled the test setup after my testing, but there wasn't anything "special".Could you share port and initiator/target configurations for RDMA?
I thought RoCE requires global pause frames or ECN/PFC. I've been told Mellanox ZTR (zero-touch-RoCE) is supported on CX4 and newer, not CX3-Pro.
