Emerald Unified KVM Features

Emerald is an award-winning IP-based KVM extension and matrix switching platform — developed by Black Box® in Ireland — that provides reliable, future-proof and high-performance 4K and HD KVM capabilities to your mission-critical IT environment.

  • Futureproof and Scalable KVM
    Start with HD and add 4K at your own pace. Scale a small point-to-point extension up to an enterprise KVM matrix of unlimited endpoints by adding additional receivers/transmitters. Use Black Box Emerald IP switches or a managed third-party IP switch.

  • Remote Access to Virtual Machines
    Enable multiple users to access any number of physical and virtual servers and desktops. Support for VMware®, Microsoft® and Citrix®, using RDP 8.1, RemoteFX and PCoIP.

  • Network Resilience
    Designed with 24/7/365 critical applications in mind, Emerald 4K is configurable with redundant network paths via SFP+ ports (fiber or copper) for fail-safe operation. Supports complete switchover to a backup control room location.

  • 4K Pixel-perfect Video
    Extend and switch HD and 4K video. Adjust compression in five steps up to pixel-perfect image transmission — every pixel visualized at 60 fps with 10-bit color depth.
