Hi Maxim, If you are just doing layer 2 the N2000 is the newer model. It has more CPU memory 1GB vs 256MB and more fabric capacity and a faster forwarding rate.  [URL] [URL]
Hello I'd like to ask the professional. For our company internal servers communication, what switch more powerful N2048 or PC6248? We would like to use just Team ports, LAG. No VLANs, no routing. Just "layer 2". Thanks. Best Regards, MAxim Krol
