Comparing the Best Console Servers for Data Centers in 2022
Console servers are critical for data center infrastructure management and remote out of band (OOB) connectivity. At a minimum, your console server should give you remote access to and control over your data center devices. However, your enterprise needs more than just the minimum—you need a console server that delivers fast, reliable network access, robust security functionality, and support for NetDevOps infrastructure and network automation. This guide compares the best console servers for data centers in 2022, so you can choose the right solution for your environment.
Please note that over the years these terms have been used to refer to what we are now calling Console Servers:
1. Terminal Server | 2. Console Switch | 3. Serial Console | 4. Console Server |

Comparing the best console servers for data centers in 2022 in alphabetical order
Let’s take an in-depth look at the hardware, features, and functionality of the best console servers for data centers in 2022.
Avocent ACS8000
The Avocent ACS8000, an advanced console server from Vertiv, comes in 8, 16, 32, and 48 serial ports RJ45 models with USB. For the ACS8000 series, Avocent added new features such as 4G LTE connectivity for WAN, OOB, and failover, as well as few environmental sensors to provide visibility into data center operating conditions.
The ACS8000’s internal hardware leaves little headroom to grow and is optimized for cost, with a dual-core ARM 766MHz CPU, and a max of 1GB RAM and 16GB flash storage. Its minimum port speeds are faster than average at 1200 bps. Security-wise, ACS8000 serial consoles lack an embedded firewall, advanced authentication features, and VPN functionality, though they do support FIPS 410-2 cryptography.
Avocent console servers come with an updated Linux OS and the proprietary DSViewTM software to help you manage and monitor your OOB solution. This includes console event logging and notifications, such as “dying gasp” alarms when systems unexpectedly lose power. However, though the ACS8000 supports ZTP for automation, but due to its ARM CPU architecture it doesn’t integrate with Docker or VM’s for to run third-party orchestration solutions.
Avocent ACS8000 Pros:
- 4G LTE WAN, OOB, and failover support
- Environmental sensor port
- Faster than average minimum port speeds
Avocent ACS8000 Cons:
- CPU, RAM, and flash storage are under par
- Lacks embedded firewall and advanced security features
- No support for Docker or third-party orchestration

Lantronix SLC 8000
The Lantronix SLC 8000 is a modular console server that comes in 8, 16, 32, and 48 port models. Each of these models can also be customized to include features like dual SFP interfaces and dual AC or DC power supplies. The modular chassis design allows for easy swapping and upgrading of the USB and RS232 interface cards, so you can start with a smaller model but increase your ports (up to 48) as needed over time.
The SLC 8000 series comes with some in-built security features, including encryption (like SSH, SSL, and AES), remote authentication (via LDAP, RADIUS, Kerberos, TACACS+, Active Directory, and NIS), and some firewall packet filtering. Out of band access and failover is provided by an optional internal, or USB dial-up modem, or an optional PremierWave XC LTE cellular card. The SLC 8000 doesn’t currently support 5G cellular technology.
In addition, Lantronix provides a centralized management and monitoring solution called ConsoleFlowTM, which includes comprehensive data logging and analysis. However, this software doesn’t appear to support or integrate with third-party automation and orchestration tools. So, your automation capabilities with the SLC 8000 will be limited to zero touch provisioning (ZTP), which could hamper your NetDevOps transformation process.
Lantronix SLC 8000 Pros:
- Modular chassis design for easy field upgrades
- Embedded firewall and security feature
- Robust data logging and analysis tools
Lantronix SLC 8000 Cons:
- Limited to 48 managed ports (either USB, RS232, or a combination of the two)
- Additional cost for add-on for LTE cellular connectivity
- No support for third-party automation or orchestration

Perle IOLAN SCG LWM
The Perle IOLAN SCG LWM console server is a robust solution that improves upon older models with on-board 2.4 and 5 GHz WiFi, integrated RJ11 V.92 modem failover, and built-in 4G LTE failover. The SCG LWM model has a modular design that supports any “mix-and-match” combination of 16 serial RJ45 or USB 3.0 interface cards up to 48 total ports.
Perle IOLAN console servers come with embedded firewall and security features such as two-factor authentication (2FA), remote RADIUS, TACACS+, and LDAP authentication, and both IPSec VPN and OpenVPN. However, the SCG LWM’s internal CPU, RAM, and flash storage are the least impressive on our list.
In addition, the Perle IOLAN SCG LWM supports zero touch provisioning, but does not integrate with third-party automation or orchestration solutions. On the plus side, it does come with device auto-discovery via LLDP (Link Layer Discovery Protocol), as well as a lifetime limited warranty.
Perle IOLAN SCG LWM Pros:
- On-board WiFi, dial-up, and 4G LTE failover
- Comprehensive firewall and security features
- ZTP and LLDP auto-discovery for some automation support
- Modular mix-and-match interface cards
Perle IOLAN SCG LWM Cons:

OpenGear CM7100
The OpenGear CM7100 line of Smart OOBTM console servers comes with 16, 32, 48, or 96* RJ45 serial ports and dual USB 2.0 console ports for a maximum of 98 managed devices. Their “smart” OOB solution is so named because it includes automatic port discovery and VLAN support. None of the CM7100 models support cellular access, so OOB and failover is provided via dual LAN ports or dual LAN/SFP ports.
Note *: Patent on 96 port serial console is assigned to ZPE systems. (Patent No. 9,905,980)
The CM7100 offers some security features such as IPSec & OpenVPN, SSL tunnels, and Secure Shell (SSHv2), as well as advanced authentication via TACACS+, Kerberos, RADIUS, and more. In addition, the CM7100 provides some gateway router features like DDNS, DHCP server, and stateful firewall with IP filtering and port forwarding. However, it does not support 2FA, SAML 2.0 (via providers like Okta, Duo, or PingID), or multi-site IPSec VPN.
The CM7100 uses ZTP and RESTful APIs for automation, and the embedded Linux operating system is programmable and extensible with third-party integrations. In addition, their Lighthouse management software can be upgraded to the enterprise edition, which supports Docker containers and Python scripts.
OpenGear CM7100 Pros:
- Automatic port discovery
- Gateway router features
- Extensible OS
- Automation support via ZTP and Lighthouse Enterprise software
OpenGear CM7100 Cons:
