And about latency, It could be negligible compared to latency at the infiniband card (~3 microsecs in front of 480 nanosecs at switch), right? > > > RAQ> c) Use the Flextronix 10U 144 Port Modular solution which will > allow us > > RAQ> to scale well in a couple years > > > But you have to pay now for an expansion that you might never get... > Or want a fancy new network technology as soon as you upgrade. Well, I most probably will be needing 48 ports in five months and 120 ports in about a year Thanks for your answer Regards -- Aquest missatge ha estat analitzat per MailScanner a la cerca de virus i d'altres continguts perillosos, i es considera que està net.
