Hi ,
Please, i am a real beginner in Infiniband interconnect !, and need help please.
I want to set up infiniband FDR over HPC cluster, I haven’t yet order the parts, but i am thinking to the followings :
- Mellanox FDR single port on servers DELL C6220, CX383A ( 56 Gbps) [I think actually this is FDR10 at 40Gbps !].
- Mellanox FDR Switch MSX6036F ( 56 Gbps).
First of all, my interest is Latency more than bandwidth, First question:
- should i buy QSFP FDR cables or QSFP QDR would work correctly ?.
- On cards & Switch descriptions , ports are mentioned as QSFP, but i see that there are QSFP+ cables, would they work too, or simply they are the same ,
In other hand, regarding software & OS, the cluster is running very well with 10GbE SFP+ on Linux CentOS, then setting up infiniband interconnect would be more complected ( things to do and things to avoid) ?
I certainly have other questions but, at this time…
Thanks for help
