Edge computing allows organizations to process data close to where it’s generated, such as in retail stores, industrial sites, and smart cities, with the goal of improving operational efficiency and reducing latency. However, edge computing requires a platform that can support the necessary software, management, and networking infrastructure. Let’s explore the 2024 Gartner Market Guide for Edge Computing, which highlights the drivers of edge computing and offers guidance for organizations considering edge strategies.

What is an Edge Computing Platform (ECP)?

Edge computing moves data processing close to where it’s generated. For bank branches, manufacturing plants, hospitals, and others, edge computing delivers benefits like reduced latency, faster response times, and lower bandwidth costs. An Edge Computing Platform (ECP) provides the foundation of infrastructure, management, and cloud integration that enable edge computing. The goal of having an ECP is to allow many edge locations to be efficiently operated and scaled with minimal, if any, human touch or physical infrastructure changes.

Before we describe ECPs in detail, it’s important to first understand why edge computing is becoming increasingly critical to IT and what challenges arise as a result.

What’s Driving Edge Computing, and What Are the Challenges?

Here are the five drivers of edge computing described in Gartner’s report, along with the challenges that arise from each:

1. Edge Diversity

Every industry has its unique edge computing requirements. For example, manufacturing often needs low-latency processing to ensure real-time control over production, while retail might focus on real-time data insights to deliver hyper-personalized customer experiences.

Challenge: Edge computing solutions are usually deployed to address an immediate need, without taking into account the potential for future changes. This makes it difficult to adapt to diverse and evolving use cases.

2. Ongoing Digital Transformation

Gartner predicts that by 2029, 30% of enterprises will rely on edge computing. Digital transformation is catalyzing its adoption, while use cases will continue to evolve based on emerging technologies and business strategies.

Challenge: This rapid transformation means environments will continue to become more complex as edge computing evolves. This complexity makes it difficult to integrate, manage, and secure the various solutions required for edge computing.

3. Data Growth

The amount of data generated at the edge is increasing exponentially due to digitalization. Initially, this data was often underutilized (referred to as the “dark edge”), but businesses are now shifting towards a more connected and intelligent edge, where data is processed and acted upon in real time.

Challenge: Enormous volumes of data make it difficult to efficiently manage data flows and support real-time processing without overwhelming the network or infrastructure.

4. Business-Led Requirements

Automation, predictive maintenance, and hyper-personalized experiences are key business drivers pushing the adoption of edge solutions across industries.

Challenge: Meeting business requirements poses challenges in terms of ensuring scalability, interoperability, and adaptability.

5. Technology Focus

Emerging technologies such as AI/ML are increasingly deployed at the edge for low-latency processing, which is particularly useful in manufacturing, defense, and other sectors that require real-time analytics and autonomous systems.

Challenge: AI and ML make it difficult for organizations to determine how to strike a balance between computing power and infrastructure costs, without sacrificing security.

What Features Do Edge Computing Platforms Need to Have?

To address these challenges, here’s a brief look at three core features that ECPs need to have according to Gartner’s Market Guide:

  1. Edge Software Infrastructure: Support for edge-native workloads and infrastructure, including containers and VMs. The platform must be secure by design.
  2. Edge Management and Orchestration: Centralized management for the full software stack, including orchestration for app onboarding, fleet deployments, data storage, and regular updates/rollbacks.
  3. Cloud Integration and Networking: Seamless connection between edge and cloud to ensure smooth data flow and scalability, with support for upstream and downstream networking.

Top 5 Data Center Mistakes and How To Avoid Them

by | Oct 9, 2024 | Data Center Management, Data Center Resilience, Increase Productivity, Micro-segmentation, Minimize Impact of Disruptions, Network Automation, Out of Band Management, Power Management, Remote Network Management, Serial Consoles, Streamline Deployments, Zero Touch Provisioning (ZTP), Zero Trust Security

Top 5 Data Center Mistakes and How To Avoid Them

Data center deployments require careful planning and execution. The sheer complexity makes it easy to stumble into common pitfalls that can compromise uptime, security, and scalability. After talking with hundreds of customers, we’ve compiled the top five data center mistakes organizations often make during deployments, with tips on how to avoid them.

1. Overlooking Isolated Management Infrastructure

In the data center, the focus is bringing production infrastructure online, including power, cabling, racks, servers, and network gear. But many project managers and architects say they wished they’d given more attention to setting up proper management infrastructure. This oversight usually leads to business challenges down the line, especially when management access relies on the production infrastructure. When a device fails or goes offline, there’s no choice but to go on-site to manually troubleshoot and recover. Many professionals admit to making this data center mistake and wish that they had considered this early in the planning process. Incorporating something called Isolated Management Infrastructure from the start can avoid this challenge, since it provides a dedicated management plane through which teams can access production gear without relying on the production network. 

Tip: Make management infrastructure a priority in your initial planning stages. This proactive approach can prevent complications later.

IMI

2. Neglecting Automation for Configuration and Scaling

Many data center implementors focus heavily on the “rack and stack” initial setup, but fail to automate processes for configuration and scaling operations. This data center mistake often leads to days’ or weeks’ worth of manual, repetitive work, while also exposing the organization to human error. A lot of people we talked to wish they’d invested just a few weeks into automating essential tasks such as switch setup, VLAN configurations, and IP address assignments, which would have saved them lots of time later on and likely helped to prevent errors. Additionally, if rearchitecting is needed, automated systems allow for quick reimplementation, minimizing the time and complexity involved. 

Tip: Dedicate time to automating routine processes. This investment will pay off in enhanced operational efficiency and reduced human error.

3. Inadequate Out-of-Band Management

When people think of out-of-band (OOB) management, a common misconception is that it is solely about Ethernet switches. However, it’s crucial not to overlook the importance of having management access to your entire device stack. Low-level access can be essential for system recovery and management. The recent CrowdStrike outage is a perfect example – when the failed devices needed to be reimaged, typical out-of-band management solutions were inadequate at providing this type of low-level access. Generation three out-of-band serial consoles, like the Nodegrid Net SR, give Ethernet, serial, and USB access, allowing teams to remote-in at the BIOS level to revive failed devices. Using this kind of comprehensive out-of-band – on a fully isolated management plane – helps teams remotely recover and confidently automate processes.

Tip: Ensure that your OOB strategy includes robust serial console access to enhance system reliability and recovery capabilities.

4. Ignoring Security Best Practices

Zero trust security is no longer just advisable, it’s essential. The typical approach is to establish direct connectivity to devices to configure, troubleshoot, upgrade, etc. But this comes with unnecessary risks, often exposing management ports to the Internet and leaving you at risk of attack. Without a fully isolated management plane and zero trust security controls, how would you recover if you were ransomware’d? This is why it’s essential to implement security controls like role-based access and multi-factor authentication, and ensure complete separation of management and production networks. 

Tip: Prioritize security by adopting a zero-trust approach and implementing rigorous access controls to safeguard your data center.

5. Cutting Corners on Out-of-Band Management

In the race for implementing AI, it’s crucial to invest in AI data center infrastructure. But organizations often cut corners on their ability to manage the underlying infrastructure that powers AI. Management access should not stop at ethernet switches; it should extend to encompass serial console access, PDUs, jump boxes, 5G connectivity, routing, WAN links, and a centralized cloud hub with secure tunnels to colocation sites. Using a comprehensive and centralized platform like Nodegrid consolidates many management devices into one while giving remote control to optimize AI’s underlying infrastructure. Aside from enhancing efficiency, this approach minimizes waste and energy consumption, which addresses environmental, social, and governance (ESG) concerns. 

Tip: Avoid the partial out-of-band management deployment. A complete system not only supports resilience and security but also contributes to sustainability goals.

 

Addressing these common data center mistakes can significantly enhance operational efficiency, security, and scalability. By prioritizing management infrastructure, automating processes, ensuring adequate out-of-band access, implementing robust security measures, and investing wisely in management systems, organizations can build resilient data centers equipped to meet the demands of today and the future.

NCSP Back side

Perle offers two console server solutions for out-of-band (OOB) management of data center infrastructure: the IOLAN SCG and the IOLAN SCR. The SCG is available in both fixed and modular form factors, while the SCR comes in four models with different combinations of 56 managed ports, allowing companies to choose the OOB management hardware that best suits their environment. Unfortunately, IOLAN solutions suffer from hardware and software limitations that can curb scalability and limit agility. This guide discusses Perle console server replacement options that enable streamlined growth through automation capabilities and vendor freedom.

Quick Links:

 

Key takeaways

  • Perle IOLAN SCG appliances offer out-of-band console server management for up to 48 devices in a fixed or modular form factor. Perle IOLAN SCR console servers come with four different managed port configurations for added flexibility.
  • Perle console servers offer some automation capabilities, like auto-discovery and zero-touch provisioning, as well as comprehensive firewall functionality. However, their underpowered hardware and closed management software prevent Guest OS hosting or third-party infrastructure automation and orchestration.
  • The Nodegrid platform from ZPE Systems overcomes these limitations with robust CPU, RAM, and storage, as well as vendor-neutral software. It enables data center scalability by providing high-density serial port configurations and supporting 3rd-party automation.
  • Nodegrid can also run networking, security, edge computing, AIOps, and more, consolidating the data center tech stack and improving operational efficiency.

 

Perle IOLAN console server overview

Perle IOLAN SCG console servers provide out-of-band management for up to 48 infrastructure devices. Fixed-form-factor models use copper Ethernet for networking and OOB, while the modular version has options for Wi-Fi, cellular, and dial-up. The modular series also has three expansion bays that support any combination of 16-port RS-232 or USB serial modules.

Perle IOLAN SCR console servers come in four different models with up to 56 managed serial, USB, and Ethernet ports, as well as optional cellular integration.

Perle console servers have automatic LLDP (Link Layer Discovery Protocol) discovery and can extend zero-touch provisioning (ZTP) to end-devices. They come with an embedded firewall, OpenVPN and IPSec VPN, and AES encryption. The PerleVIEW cloud-based management software provides centralized monitoring and control of all connected data center infrastructure.

 

Why consider Perle console server alternatives

IOLAN console servers have an underpowered 500 MHz core 32-bit ARM processor, 4GB of flash storage, and 1GB RAM. This hardware may be sufficient for basic infrastructure management workflows and ZTP, but it prevents Guest OS hosting and more advanced automation. The Perle platform also doesn’t integrate with any third-party automation or orchestration solutions.

An inability to fully automate infrastructure management workflows – or to orchestrate those tasks that can be automated – ultimately limits operational efficiency and data center scalability. Consequently, IT teams can’t effectively support the needs of the growing business, adapt to strategy changes, or focus on revenue-driving innovations like artificial intelligence and machine learning (AI/ML).

What’s needed is an open platform that can manage any device, automate any workflow, and work with third-party software to provide a fully integrated infrastructure orchestration experience.

 

Perle console server replacement options from ZPE Systems

Nodegrid is a family of vendor-neutral console server solutions from ZPE Systems. It comes in four models:

The Best Serial Consoles for Linux

by | Sep 25, 2024 | Data Center Resilience, Minimize Impact of Disruptions, Monitoring & Reporting, Out of Band Management, Power Management, Remote Network Management, Serial Consoles, Vendor Neutral Platform, Zero Touch Provisioning (ZTP)

Photos of the best serial consoles for Linux

The serial console port on a Linux device allows administrators to manage the machine via the command line interface (CLI), without a keyboard, mouse, or monitor attached. Serial console management is useful for performing administrative tasks on headless Linux servers (meaning, those without ports for a keyboard or monitor) and embedded Linux systems like routers and storage devices.

While it’s possible to directly connect a laptop or Intel NUC jump box to the serial console port on a Linux device with a serial cable, this only allows you to manage one machine at a time, so it’s inefficient at scale. A serial console server (also known as a serial console or console server) provides multiple managed serial ports that administrators can connect to Linux machines, as well as many other devices. It unifies the management of all connected machines so administrators can control them all from one place, significantly streamlining infrastructure workflows.

Enterprise serial consoles for Linux provide additional capabilities like out-of-band (OOB) management, infrastructure automation, and embedded security. This guide compares the best solutions to help you choose the right console server for your enterprise.

How to use the serial console port on a Linux device

The Linux kernel does not support serial console capabilities by default, so it must be configured to output console messages to the serial port first. This involves modifying the bootloader to specify new kernel options, formatted like so:

console=device,options

device:         tty0 for the foreground virtual console
                ttyX for any other virtual console
                ttySx for a serial port
                lp0 for the first parallel port
                ttyUSB0 for the first USB serial device

options:        depend on the driver. For the serial port this
                defines the baudrate/parity/bits/flow control of
                the port, in the format BBBBPNF, where BBBB is the
                speed, P is parity (n/o/e), N is number of bits,
                and F is flow control ('r' for RTS). Default is
                9600n8. The maximum baudrate is 115200.

ZPE Systems and Starlink setup guide

Most organizations rely on critical IT in order to serve their essential business functions. A reliable method to maintain critical IT is to use dedicated out-of-band (OOB) management networks, which traditionally have relied on plain old telephone service (POTS) lines or dedicated telephony circuits for remote access. However, these traditional links come with high costs, lots of complexity, and slow performance, which make them difficult to deploy and maintain.

Enter Starlink, a satellite-based Internet service that offers a cost-effective and scalable alternative for out-of-band remote access. This post discusses how Starlink solves these common problems and gives you a free guide that walks you through the setup process.

 

Problem: POTS and Telephony Lines Are Expensive

For decades, IT professionals have relied on POTS and telephony lines for OOB management, mainly because these lines remain operational even when the primary data network goes down. A major problem is that POTS lines are increasingly expensive to install and maintain, particularly in remote or rural areas. Additionally, 4G/5G LTE options aren’t always available due to coverage limitations or large enough data plans. The shift towards VoIP (Voice over IP) and digital communications has made POTS lines even less relevant, with many service providers phasing out support. This leaves businesses with fewer options and higher costs for maintaining these legacy systems.

Solution: Starlink is Cost-Effective

Starlink offers a much more cost-effective solution. You can use off-the-shelf routers to set up an OOB management network for a fraction of the cost of traditional methods. Starlink also has a relatively low monthly subscription fee and straightforward pricing model, which make it easy to budget and plan IT expenditures. If components fail or break, you can typically repair or replace them yourself to get back up and running quickly.

Figure 1: Starlink requires only a dish, router, and few other components, making it a cost-effective alternative to expensive POTS lines.

Problem: Traditional Lines Are Difficult To Scale

Traditional POTS-based systems are notoriously difficult to scale, often requiring significant infrastructure investments and complex configurations. Copper wiring is expensive to install and maintain, and as more connections come online, switching systems must be upgraded. On top of this, POTS lines are being phased out, which means there are fewer resources being devoted to scaling and maintaining them.

Solution: Starlink is Simple to Set Up and Scale

Starlink entirely eliminates the need for telephony lines, and is a simple and scalable solution for OOB remote access. You can find the full list of components in our setup guide below, but with a Starlink terminal, compatible router, and minimal configuration, you can scale your OOB network wherever you have Starlink coverage. This ease-of-use extends to day-to-day management as well. Starlink’s satellite service offers global coverage, meaning you can manage your network devices, servers, and other critical infrastructure from virtually anywhere in the world.

The setup process for Starlink includes simple instructions that you can follow on your smartphone

Figure 2: Starlink comes with a straightforward out-of-box experience and step-by-step instructions. You can set up an out-of-band network in about one hour.

Problem: POTS Lines Lack Performance

POTS is designed primarily for voice communication and offers extremely limited bandwidth. It can’t support modern data services (such as video or high-speed internet) efficiently. As out-of-band management advances with data and video monitoring capabilities (such as AI computer vision), POTS infrastructure just doesn’t have the bandwidth to keep up.

Solution: Starlink Meets Modern Performance Requirements

Starlink provides high-speed internet, at speeds that typically range from 50 to 200Mbps. The connection handles much larger volumes of data than POTS lines are capable of, and Starlink’s low-Earth orbit satellites reduce latency to as low at 25ms compared to the typical 150ms of POTS lines. Out-of-band using Starlink means that IT teams can manage more systems and data, and have a more responsive experience, whether they’re managing edge routers across their bank branches or monitoring the cooling systems in their distributed colocations.

What is Passive Optical Networking?

What is Passive Optical Networking (PON)?

Passive optical networking (PON) is a high-speed broadband technology that enables the delivery of multiple services over a single fiber optic cable. XGS-PON – 10G Symmetrical PON –  offers speeds of up to 10 Gbps downstream and 10 Gbps upstream (hence the term ‘symmetrical’), making it ideal for applications such as video streaming, online gaming, and cloud computing.

 

What Problems Does PON Solve for Out-of-Band Management?

PON addresses the issue of efficiency in terms of both uplink costs and bandwidth usage. Traditional POTS lines and dedicated circuits rely on legacy infrastructure that requires regular maintenance. This infrastructure must scale as more out-of-band devices are added to the network, which increases costs and energy consumption. On top of this, using a 10G uplink for a serial console’s 10K traffic is like throwing away 99% of that high bandwidth. Per Gartner’s Market Guide for Optical Transport Systems report (Published 20 November 2023) the best way to “lower cost and energy per transported bit” is by using technologies such as passive optical networking.

Because PON uses passive optical splitters that have no moving parts or powered components between the central hub and end users, PON is much more efficient for deploying serial consoles close to target assets. These out-of-band devices can be deployed in large quantities and close to the network edge, with up to 256 devices sharing one uplink. This reduces cabling and power requirements, and is ideal for MSP and campus operators, where there are many out-of-band devices distributed over long distances. 

 

More About PON: GPON and XGS-PON Technologies

Passive Optical Networking (PON) leverages time-division multiplexing (TDM) and different wavelengths of light to transmit and receive data on a single fiber strand. This allows efficient communication among up to 256 devices over a single fiber. Initially developed for fiber-to-the-home (FTTH) deployments, PON technology has evolved to facilitate the addition of network nodes with minimal infrastructure changes. GPON (gigabit-capable PON) and XGS-PON use different frequencies for upstream and downstream data transmission. The upstream headend, known as the Optical Line Terminal (OLT), manages and coordinates the time slots allocated to downstream Optical Network Units (ONUs) for data transmission.

 

GPON and XGS-PON Support on ZPE Systems’ Nodegrid SR Gateway

ZPE Systems’ Nodegrid SR appliances, which are used as out-of-band access nodes or complete branch gateways, now support GPON and XGS-PON technology (patent pending) via SFP and SFP+ ports. The Nodegrid SR family is offered in multiple form factors to be right-sized for deployments in branch offices, factories, smart buildings, and industrial environments (such as for SCADA).

Having support for GPON and XGS-PON means network engineers now have a flexible choice of high-speed uplink technologies. This versatility makes the Nodegrid SR gateway suitable for edge deployments, where it can establish an OOBI-WAN™ (out-of-band infrastructure WAN) link, and for data centers, where it enhances uplink efficiency. Given the low bandwidth requirements of serial console and out-of-band communications, PON technology is well-suited for these applications. A single fiber strand can be shared among hundreds of out-of-band and serial console devices using passive optical splitters. Organizations can deploy out-of-band devices close to the racks and edges of the network in a cost- and energy-efficient manner. Additionally, ZPE devices support ONU SFPs compatible with third-party OLT headends, ensuring broad interoperability and integration.

 

Benefits of Using XGS-PON with ZPE Systems’ Nodegrid SR Gateway

The benefits of using XGS-PON with ZPE Systems’ Nodegrid SR gateway include:

  • High-Speed Connectivity: XGS-PON delivers symmetrical speeds of up to 10 Gbps, making it ideal for high-bandwidth applications like video streaming, online gaming, and cloud computing. This ensures consistent and high-quality service for end-users.
  • Cost-Effectiveness: Deploying XGS-PON is a cost-effective solution for delivering high-speed broadband services, especially in scenarios where upgrading existing infrastructure may be challenging.
  • Scalability: The Nodegrid SR Gateway, acting as an ONU, can connect up to 256 serial consoles through a single fiber strand. PON’s use of asymmetric wavelengths and TDM enables multiple devices to share the same fiber strand efficiently. Optical splitters, which require no external power, facilitate the sharing of fiber between multiple ONUs, which makes scaling much more cost and energy efficient.
  • Reliability: The Nodegrid SR gateway is proven by service providers worldwide. Its robust design and compatibility with various network configurations make it a reliable choice for delivering high-quality broadband services.
