Introducing the High-Speed

Introducing the high-speed refers to the deployment of a network infrastructure that supports faster data transfer rates and more reliable connectivity, allowing organizations to take advantage of new digital technologies and better support the needs of users.

High-speed networks are designed to provide faster and more reliable data transfer rates, which can support a range of applications, from video conferencing to cloud computing. This is achieved through the use of advanced network technologies, such as fiber-optic cabling, 10Gbps Ethernet switches, and wireless access points that support the latest Wi-Fi standards.

One key benefit of high-speed networks is the ability to support large amounts of data transfer at faster rates, enabling organizations to take advantage of big data analytics, artificial intelligence, and machine learning. This can help organizations make more informed business decisions, improve customer service, and identify new opportunities for growth.

Another benefit of high-speed networks is the ability to support remote work and collaboration, which has become increasingly important in the wake of the COVID-19 pandemic. With a high-speed network infrastructure, remote workers can access company resources and collaborate with colleagues seamlessly, without experiencing connectivity issues or lag.

To introduce a high-speed network, organizations need to invest in the right network technologies, including high-speed switches, routers, cabling, and access points. They also need to ensure that their IT teams have the expertise and resources required to deploy and manage these technologies effectively.

Maximize Bandwidth

Maximizing bandwidth refers to optimizing the use of available network bandwidth to ensure that data can be transferred quickly and efficiently between network devices.

Bandwidth is the amount of data that can be transmitted over a network connection in a given amount of time. When multiple devices on a network compete for bandwidth, data transfer rates can slow down, leading to slower network performance and decreased productivity.

To maximize bandwidth, organizations can implement a range of strategies and technologies, including:

  • Network monitoring: By monitoring network traffic and identifying bandwidth-hogging applications and devices, organizations can take steps to prioritize network traffic and ensure that critical applications receive the bandwidth they require.
  • Quality of Service (QoS) management: QoS management enables organizations to prioritize network traffic based on the type of application or service being used. For example, video conferencing and VoIP calls can be prioritized over email and web browsing.
  • Bandwidth shaping: Bandwidth shaping involves limiting the amount of bandwidth that certain applications or devices can use. This can help prevent bandwidth-intensive applications from impacting the performance of other applications.
  • Network upgrades: Upgrading network infrastructure, such as switches and routers, can help organizations take advantage of faster data transfer rates and support more devices on the network.
  • Cloud services: Cloud-based services can help reduce the amount of bandwidth required to transfer data by offloading some of the processing and storage to cloud-based servers.

Scalable Networking Solutions

Scalable networking solutions refer to network infrastructure and technologies that can easily expand or contract to accommodate the changing needs of an organization.

Scalability is essential for organizations that are growing or undergoing digital transformation, as it enables them to easily add or remove network devices, applications, and services without disrupting existing operations. This can help organizations reduce costs, improve efficiency, and support new business opportunities.

There are several key components of scalable networking solutions, including:

  • Network virtualization: Network virtualization allows organizations to create multiple virtual networks on a single physical network infrastructure. This enables organizations to segment their network for different users or applications, which can help improve performance and security.
  • Software-defined networking (SDN): SDN enables organizations to manage their network infrastructure through software, rather than hardware. This provides greater flexibility and agility, allowing organizations to easily scale their network infrastructure up or down as needed.
  • Cloud-based networking: Cloud-based networking solutions enable organizations to easily deploy and manage network infrastructure and services in the cloud. This provides greater flexibility and scalability, as organizations can quickly provision and deprovision resources as needed.
  • Network automation: Network automation tools can help organizations streamline network management and configuration, reducing the time and resources required to manage network devices and services.

About Refurbished Products

Refurbished products are typically refurbished by an Original Manufacturer or an affiliate of the manufacturer or 3rd party facility. This product may have minor blemishes due to normal product usage and doesn't necessarily come with documentation and software unless indicated, but has been well tested and generally has never had any defects.

For all your expansion module needs, we've got you covered with high-performance devices that increase functional capability and ease business processes.

You can talk to any of our staff and consult on what would be the best way forward when getting an expansion module to complement and enhance existing infrastructure, meet your immediate and future needs.

We have hardware level 12 with firmware 3.0 or higher modules that allow for the installation of up to 14 expansion modules below the base module for resilient performance. Expansion modules connect to the base module using USB Type-A connectors. That's not all, we have hardware level 11 and lower that supports up to 9 expansion modules.

With an expansion module, you get additional cartridge storage as well as tape drive capacity. We have expansion modules that contain up to two drives and two power supplies. You can choose to have the expansion module with tape drives and power supply installed so that it makes setup easier from your end. Expansion modules will need a power supply only if you install a tape drive in it. A single power supply can actually power two drives. However, you can add a second power supply for redundancy purposes. Without a tape drive, the expansion module is powered via the USB cable connected to the base module.

Expansion modules require 2U rack space and will be shipped with the necessary mounting hardware used to secure it to the rack.
