Hello,
I need to connect 3 systems having 10 GB Intel onboard nics.
Fiber/DACs/crossover cables are not an option so it has to be a switch.
Because of space, heat and power constraints, it is preferable to have one single switch having (24 x 1 GB) + (4 x 10GBase-T if possible or SFP+) ports.
Actually, most 24 port gigabit switches have 2 or 4 SFP+ uplink ports; don't remember actually seing one with 4 10GBase-T ports.
Alternatively, I could use a switch with 4-8 x 10GBase-T ports in addition to the one with 24 gigabit ports that's already available.
The switch has the following requirements:
- depth: 255mm at most (shallow wall-mount rack)
- fanless or fan-modable
- managed: web or cli
The switches I was able to find (Aruba 1930 24G 4SFP/SFP+, Cisco Catalyst C1000-24T-4X-L) have 4 SFP+ uplinks.
The Aruba 1930 is cheaper but has the SFP+ ports placed in a 2x2 square pattern (worse heat-wise).
The Catalyst 1000 has the SFP+ ports placed in a single line (better heat dispersion) but is much more expensive.
I have considered CRS305-1G-4S+IN but Mikrotik's guidelines advise against two S+RJ10 placed side by side.
The same argument goes for using RJ-45 SFP+ modules in the two switches above.
As a last resort a CRS309-1G-8S+IN using RJ-45 SFP+ modules in every other port could do the trick but I would rather use one without transceivers.
The XG-6PoE would have been right for my use case if it had either 2 more copper ports or no PoE.
So, what's your take on the above? Any gotchas, ideeas or recommendations for other switch models from the following categories?
1. 24 x 1 GB + 4 x 10GBase-T ports or 4 SFP+ ports (placed in a single line and spaced further apart)
2. 4/6/8 x 10GBase-T ports (fanless and managed)
Do you think I could get away with 3 or 4 RJ-45 SFP+ modules in close proximity given the current temperature inside the rack being around 38 degrees celsius?
The Aruba switch has only one 1G RJ-45 module in the accesories section. Are the 10GBase-T transceivers functional if installed in the SFP+ uplink ports?
Thanks.
