Comparing the Best Console Servers for Data Centers in 2023

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 infrastructure and network automation. This guide compares the best console servers for data centers in 2023, 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. Serial Console 2. Serial Console Switch 3. Serial Console Server 4. Serial Console Router

​Comparing the best console servers for data centers in 2023 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 2023.

Avocent ACS8000

The Avocent ACS8000, an advanced serial 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, due to its ARM CPU architecture it doesn’t integrate with Docker or VMs 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 Uplogix LM83X

The Lantronix Uplogix LM83X console server comes with three expansion bays which make it capable of managing up to 104 devices over serial. It uses 4G LTE cellular, V.92 modem, fiber, DSL, or satellite for OOB and failover, providing a lot of flexibility for data centers in hard-to-reach areas. The LM83X comes with some built-in security features, including secure SSH tunnels, remote authentication (via LDAP, RADIUS, or TACACS+), and IP and caller ID filtering. 

Since Lantronix purchased Uplogix, the LM83X can be managed using the Lantronix Control Center on-premises software, which includes comprehensive device monitoring capabilities such as monitoring for device CPU and memory utilization, interface status and statistics, and terminal session commands. Control Center also provides some automation and playbook capabilities using the Lantronix Rules engine for routine management, monitoring, and recovery workflows. However, it does not support any third-party network automation tools or custom scripts. 

Additionally, while the LM83X has 256 GB of NVMe storage, its ARM CPU architecture prevents it from running VMs, Docker containers, and third-party automation and orchestration solutions. Another thing to keep in mind is that Uplogix was purchased by Lantronix, one of their biggest competitors, which makes the future of LM83X support and integration uncertain.

 

Lantronix Uplogix LM83X Pros:

  • Three expansion bays to support up to 104 serial devices
  • Flexible OOB and failover options
  • Robust device monitoring tools

Lantronix Uplogix LM83X Cons:

  • No support for third-party automation or orchestration
  • Can’t run Guest OSes or third-party apps
  • Future of support is uncertain

Opengear CM8100

The Opengear CM8100 line of Smart OOB™ 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 CM8100 models support cellular access, so OOB and failover is provided via dual LAN ports or dual LAN/SFP ports. 

Note *: 96-port model is a 2RU (two rack unit) serial console server

The CM8100 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 CM8100 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 CM8100 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 CM8100 Pros:

  • Automatic port discovery
  • Gateway router features
  • Extensible OS
  • Automation support via ZTP and Lighthouse Enterprise software

Opengear CM8100 Cons:

  • No cellular access
  • No support for 2FA or SAML 2.0

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:

  • Very limited CPU, RAM, and flash storage
  • No third-party integrations with Docker, orchestration, etc.

ZPE Nodegrid Serial Console Plus (NSCP) 

The Nodegrid Serial Console (NSC) family of console servers helps consolidate and streamline your data center management by providing up to 96 serial RJ45 ports in a 1U form factor device.  ZPE holds the patent for 96 port serial consoles in patent (Patent No. 9,905,980). The Nodegrid Serial Console Plus (NSCP) comes with built-in 4G/5G LTE and WiFi for failover and OOB access, as well as device auto-discovery via network scan and custom probes.

The NSCP really shines when it comes to security and automation and hosting apps and VMs. It is built with CPU and memory headroom and boasts on-board hardware security features like BIOS protection, TPM 2.0, UEFI Secure Boot, and geofencing. Plus, the embedded firewall offers advanced features like selectable cryptographic protocols and cypher suite levels, multi-site IPsec VPN, AD/LDAP, RADIUS, TACACS+, and Kerberos authentication, as well as 2FA and SAML 2.0.

Another major benefit of the NSCP serial switch is that it runs on the open, Linux-based Nodegrid OS with full support for NetOps automation solutions like Ansible, Chef, Docker, and Puppet. Because ZPE hardware uses Intel X86 CPUs, it can natively run VM and Docker applications that run on Linux OS. In addition, you can monitor and administer your Nodegrid appliances with ZPE Cloud, a vendor-neutral, web-based infrastructure management solution. ZPE Cloud consolidates all your data center and cloud appliances behind one pane of glass for efficient management, automation, and orchestration.

ZPE Nodegrid Serial Console Plus Pros:
