Cyclades, Avocent & Vertiv - the physical layer of uptime
A Brazilian-founded console-server pioneer, the KVM leaders, and Liebert's computer-room weather - consolidated into the company whose product is uptime itself.
Cyclades - founded in Fremont by Brazilian engineers, an early Linux champion - built the out-of-band discipline: the console path that shares no fate with the network it manages. Through Avocent's KVM heritage and Emerson Network Power (whose other root is Ralph Liebert's 1965 precision cooling), the lineage became Vertiv: access, power, and cooling as one problem, now the constraint the AI build-out plans around. The name also earns an honorable footnote: Pouzin's CYCLADES research network, TCP/IP's credited French ancestor.
The profile covers the 1989 Brazilian founding, the console-server category, the 2006 Avocent acquisition, Emerson Network Power and the Liebert root, the 2016 Vertiv carve-out, and the AI-density era.
Founding stories
Cyclades Corporation
Founded by Brazilian engineers in Fremont, Cyclades built the discipline of reaching equipment when the network is down: serial console servers, out-of-band paths, remote power - the last-resort plane every operator prays they configured. An early and vocal Linux adopter (its console servers ran and championed open source), Cyclades became the name on the RJ-45-to-serial adapters in a generation of data-center crash carts - and a quiet landmark of the Brazilian technology diaspora.
Liebert (Vertiv's physical-layer root)
Ralph Liebert built the first precision air conditioning made for computer rooms - the recognition that machines need their own weather. Liebert's cooling and UPS lines, acquired by Emerson in 1987, became the backbone of Emerson Network Power: the other half of the story that ends in Vertiv, where the console server and the CRAC unit share a badge - management and environment, the two halves of physical uptime.
The timeline
- The console-server category
Cyclades' terminal and console servers turn 'drive to the site with a laptop and a cable' into a network service - out-of-band access as a designed layer, not an emergency improvisation.
- Avocent forms
Apex and Cybex - the two KVM-switch leaders - merge as Avocent: keyboard, video, and mouse over distance, the other remote-hands technology of the era.
- Cyclades joins Avocent
Avocent acquires Cyclades (~$90 million): serial consoles and KVM under one roof - the complete out-of-band toolkit, Linux heritage included.
Deal figure per the public record.
- Into Emerson Network Power
Emerson Electric acquires Avocent (~$1.2 billion), joining it to the Liebert cooling and power lines - management plane and physical plane consolidated.
- Vertiv
Emerson carves out Network Power to Platinum Equity (~$4 billion); renamed Vertiv, it goes public in 2020 - UPS, cooling, PDUs, and the Avocent/Cyclades access heritage as one company whose product is, effectively, uptime itself.
Deal figures per the public record.
- The AI density era
As racks climb from kilowatts toward the tens, Vertiv's problem set - power, liquid cooling, and still that serial console when everything else is dark - becomes the constraint the whole industry plans around.
Flagship products and solutions
- Cyclades TS/ACS console serversThe out-of-band access line - serial consoles reachable when the production network is not.
- Avocent KVM and DCIMRemote keyboard-video-mouse and the data-center infrastructure management layer that grew from it.
- Liebert power and coolingPrecision cooling and UPS - the environmental half of keeping the racks alive.
Key innovations
- Out-of-band as architectureCyclades made the management plane's independence a design principle: a path to the console that shares no fate with the network it manages - the discipline every runbook on these pages assumes.
- Uptime as a product categoryThe Vertiv consolidation named a truth: access, power, and cooling are one problem - the physical layer of availability.
Main markets
Vertiv today is one of the defining suppliers of the AI build-out - power and cooling at unprecedented density - with the Avocent/Cyclades access lineage still in the catalog.
Analyst standing
- The entry with a homeland note: a Brazilian-founded company at the root of the out-of-band discipline - and, one honorable name-twin away, Pouzin's CYCLADES network, the French datagram pioneer TCP/IP's authors credit. Two lineages, one name, both worth knowing.
