I've added some fiber channels between the machines that constitutes my BeegFS cluster in an effort to increase throughput. However, I have to leave the old coppy ethernet in place with its addressing intact for backwards compatibility.

Is there a way I can edit the existing setup to work as it is, only over a different IP range? Everything is set up to operate on 192.168.9.0/24 with management running on 192.168.9.101. Do the addresses of storage-targets and management server go down into a set of files I can simply edit?

I don't get exactly the question but first of all: BeeGFS does not support the Fiber Channel protocol nor it's a block device sharing like an FC device, it needs TCP/IP networking or RDMA (with Infiniband, RoCE or Omni-Path). BeeGFS is much more like a filer than a SAN storage.

That's stated on the product brief: https://www.beegfs.io/c/home/key-aspects-of-beegfs/

Where it reads: BeeGFS is built on highly efficient and scalable multithreaded core components with native RDMA support. File system nodes can serve RDMA (InfiniBand, (Omni-Path), RoCE and TCP/IP) network connections at the same time and automatically switch to a redundant connection path in case any of them fails.

There's also the same question on the BeeGFS FAQ: https://www.beegfs.io/wiki/FAQ#net_types

That's the answer regarding the Fiber Channel question. Regarding the IP change, you can aggregate multiple interfaces and consequently multiple IP addresses. To achieve this you just configure the connNetFilterFile and connInterfacesFile in each configuration file on the machine that provides the BeeGFS service, there's more info on the FAQ too: https://www.beegfs.io/wiki/FAQ#multiple_nics

  • It is currently operating over TCP/IP, and will remain so. It's set up with all nodes addresses on one particular subnet. I would like to alter all configurations on all machines to use a different subnet instead. When I set it all up, presumably the addresses and hostnames I entered as part of the setup went into a configuration somewhere, but I would like to alter those parameters to ensure that it communicates over a different subnet that is faster. – Jarmund Jul 21 '21 at 11:00
