ATEN 40-Port Multi-Interface Cat5 KVM over IP (1 Local/4 Remote) — KN4140VA ($11,127.00) Review
ATEN KN4140VA 40 port multi-interface Cat5 KVM over IP 1 local 4 remote enterprise data center
ATEN's largest single-chassis KVM-over-IP switch, spanning 40 mixed-interface servers with room for four simultaneous remote sessions alongside one local console user.
Overview
The KN4140VA tops ATEN's KN4000 series at 40 ports, using the same CI adapter cable system as the smaller KN4124VA and KN2124VA to accept VGA, DVI, HDMI or DisplayPort servers on any port within one chassis.
Multi-User Remote Access
Supporting four concurrent remote users plus one local console means up to five administrators can each be working on different servers in the rack simultaneously, which matters for large NOCs where several engineers cover the same server bank across shifts.
Comparison to Alternatives
Against the KN4124VA (24 ports, same 4-remote-user capacity) and the KN2124VA (24 ports, 2 remote users), the KN4140VA is the choice when port density outgrows 24 but the OmniBus KG-series' console-less architecture isn't wanted. For pure IP scale without a local port, ATEN's KG0032 covers a similar server count with different management software.
