First time I'm seriously pondering bringing 10GbE straight to compute
For 64 servers (32 to a cabinet) and an HPC system that spans two racks
what would be the common 10 Gig networking topology be today?
- One large core switch?
- 48 port top-of-rack switches with trunking?
- Something else?
I was going to suggest two Gnodal rack top switches, linked by a 40Gbps link
I see though that their GS7200 switch has 72 x 10Gbps ports - should do you just fine!
