RoCE v2 configuration with Linux drivers and packages

is it possible to configure RoCE v2 with Connectx-4 card without MLNX_OFED? can someone please share info if there is any guide/doc available to configure with Linux drivers and packages? I tried to do with drivers and packages but I am not able to succeed. When I used MLNX_OFED, RoCE is configured successfully.

Hi Vetri, Thank you for posting your question on the Mellanox Community. Instead of using MLNX_OFED, you can use the OS distributed drivers for our adapters. These are called INBOX drivers. The following provides you the User Manual and Release Notes for some of the distributions which include the INBOX driver for our adapter. The User Manual…

MHGH-28XTC-full_height_bracket1-5.stl

This is a full height bracket for MHGH28-XTC cards, for 3D printing. (this 1-5 version is a bit better fit than the previous 1-2 version) Seems ok (so far) when printed at 0.1mm with ABS. Fits in my mid-tower ATX cases well. There's a low profile version of the card here, if that's useful too: MHGH-28XTC-low_profile_bracket1-7.stl

No worries at all Romain. And yeah, definitely use whatever equipment is handy. On the other hand, if you're having fun with your 3D printer making stuff and feel like expanding your skills into other areas, it's possible to get a decent desktop/workbench CNC machine for around the same price as a good (consumer grade) 3D printer. I went the…

On the Firmware page for ConnectX (here: http://www.mellanox.com/page/firmware_table_ConnectXIB), there's firmware for many cards... but the MHJH29 (dual, QDR, CX4) is not there, only the MHQH (QSFP insteqd of CX4). They are revision X5. Anyone know where I could find the latest firmware ? (Picture of the cards with 3D printed brackets in… (Show more Show less)

> Service for this Hardware and FW has ended. So it will not be hosted on our site. Thank you for your help. Seems this new firmware is no newer than the one I already have, unfortunately. Those are 10+ years old cards... no surprise they are difficult to put back in service. Cordially & thanks again for the great support,

Bringing a SX6012 back to life

Hello gents Pardon this sheep, this is my first experience with any InfiniBand technologies at all. I've gotten my hands on a SX6012 through some distant work connections that nobody seems to know what to do with it so I figured let's get cracking. Upon power up, it throws the message "System is initializing! This may take a few minutes" ,… (Show more Show less)

Suggestions for *quiet* Infiniband switch?

Does anyone have suggestions for a quiet Infiniband switch, suitable for home use? Preferably 8+ CX4 ports (can be 16, 24, 30+, etc), DDR and is fairly quiet. Fanless - or close to - would be awesome. Asking because a few years ago I bought a Topspin/Cisco SFS 7000 on eBay. Similar to the one here now (no, I'm not the vendor and I don't… (Show more Show less)

Hi Mike, This isn't an area of things I know about any more, so I can't help you directly. On the other hand, as a general thought though you'll probably have better luck if you ask on the ServeTheHome forums: Networking | ServeTheHome and ServeThe.Biz Forums They're very active, and have lots of helpful members right into stuff like…

comparasion of one-sided VS two-sided operations

Hi, As we know, RDMA support one-sided operation(i.e. write/read) and two-sided operation(i.e. send/receive), according to literature(e.t. pilaf, ATC'13), researchers claims that: one-sided operation perform better than two-sided operation both in throughput and latency, NICs can achieve 2.45 million write/read operations per second while 0.7… (Show more Show less)

Ethernet mode non-functional with recent CentOS7 kernels and ConnectX-2 cards?

Hi all, Is anyone else around running CentOS 7 x64 and ConnectX (1/2/3) series cards in eth mode? Asking because after rebooting my CentOS 7 x64 (1708) desktop this evening after a yum update, the Mellanox ConnectX-2 card in it (set to run in ethernet mode) refused to come up correctly. That was with the latest kernel (installed yesterday)… (Show more Show less)

Understood Viki. That may have had something to do with why I opened this topic in the Hobby and Home Users Group, where it's common to use gear sourced from (eg) Ebay and similar. Regarding the problem itself, it's been confirmed by RH staff due to someone else reporting the same problem (I guess with a newer card). A working solution is…
