I’d be curious to hear if all these arguments against iSCSI shouldn’t also
apply to NSD protocol over TCP/IP?

Two things that I am already aware of are: 1) use jumbo frames, and 2)
run iSCSI over it’s own private network. Other things I should be aware
of?!?
Yes, don't do it. Really do not do it unless you have datacenter
Ethernet
Using iSCSI with Spectrum Scale is definitely do-able. As with running Scale
in general, your networking needs to be very solid. For iSCSI the best
practice I’m aware of is the dedicated/simple approach described by JF below:
one subnet per switch (failure domain), nothing fancy like
I have been running GPFS over iSCSI, and know of customers who are also.
Probably not in the most demanding environments, but from my experience
iSCSI works perfectly fine as long as you have a stable network. Having a
dedicated (simple) storage network for iSCSI is probably a good idea (just
like
Kevin,
Ethernet networking of today is changing very fast as the driving forces
are the "Hyperscale" datacenters. This big innovation is changing the world
and is happening right now. You must understand the conversation by
breaking down the differences between ASICs, FPGAs, and NPUs in modern
