These are mezzanine cards for M-series Dell blade servers. There are 3 different cards available with 5 different part numbers:
0J05YT - QDR
0P90JM / 0CDMG5 - FDR10
0K6V3V / 08PTD1 - FDR
Regardless of which model, they all have “CX380A” printed on the cards. Is this some stripped down silicon? Does anyone know the difference between MCX380A and a regular CX3 card such as MCX354A?
The only documentation of them that exists is this PDF:
In the document there are screenshots of terminal sessions implying a 56 GbE and VPI capability for the FDR cards, but it not mentioned explicitly anywhere.
The documentation for the SwitchX M4001 series that go with these cards is equally vague:
In fact, these are really product sales/data sheets. Can anyone point me to a real operators manual for these products?
Most ConnectX-3 products offer ethernet, but why isn’t it explicitly mentioned anywhere on these PDFs? It says:
"Applications utilizing TCP/UDP/IP transport can achieve industry leading
throughput over InfiniBand or 10/40/56GbE. The hardware-based stateless offload engines in ConnectX-3 reduce the CPU overhead of IP packet
transport. Sockets acceleration software further increases performance for
latency sensitive applications"
Which reads like a copy/paste from a general CX3 literature and not specific to these cards.
Can anyone confirm if there is a 40 GbE or 56 GbE capability?
We will be using these for Ceph, and in these modern times expansion options for the M1000e are lacking, and the ConnectX-3 is the fastest option we have, but I would rather not have to use IPoIB for Ceph.
I need to know if we can run ethernet on these parts.
