LARGEST/DYNAMIC SOLUTION: Largest/Dynamic Solution: Over-IP HD KVM with OTC Switching For environments requiring maximum scalability and flexibility, an Over-IP HD KVM solution built on over-the-counter (OTC) GigE switches offers a compelling alternative to proprietary high- performance KVM systems. KVM-Over-IP solutions deliver a uniquely scalable and dynamic HD- KVM Over-IP architecture that is virtually unlimited in expansion. Unlike fixed port-based proprietary systems, it leverages standard TCP/IP protocols and conventional IP addressing to create a matrix that can grow virtually without limit. This flexibility allows organizations to deploy across large facilities using OTC GigE switches, avoiding vendor lock-in while enabling dynamic user-to- resource mapping. Performance & Feature Considerations: • Frame rates: 38fps (standard) vs. 60fps (high-performance) • HID support with extended functionality • USB 2.0 and USB data transfer capabilities • CD-quality audio transmission vs. Digital • Multi-display support from a single target device Compared to propietary KVM systems like Thinklogical and IHSE, the Over-IP KVM is generally more cost-effective — primarily due to its compatibility with OTC switching infrastructure. However, to ensure proper performance, additional investment in high- throughput core switches is required. Frame-rate demands per workstation and total system scale must be factored into switch selection. While generally more affordable than proprietary KVM platforms like Thinklogical or IHSE Over-IP KVM requires thoughtful infrastructure planning. Proprietary systems require proprietary switching hardware, whereas OTC-based deployments demand separate investment in high-throughput core switches — especially when targeting 60fps performance across multiple workstations. Backbone Design & Switching Strategy Cost-per-port comparisons can be misleading. To achieve true parity with proprietary systems, your GigE backbone must support high-volume throughput and manage multicast traffic effectively — particularly for any Share-Mode functionality, which relies on IGMP and multicast protocols. Not all OTC switches are created equal. While name-brand GigE switches may appear sufficient, many lack the bandwidth, traffic shaping, and reliability needed for full system utilization. To ensure performance, OOBAXS recommends switches from enterprise- grade manufacturers such as Cisco, Extreme Networks, HP, or advanced equivalent — vendors with proven capabilities in handling large-scale multicast environments. Some OTC switches may technically meet these demands, but selecting the right one requires deep research and validation. The backbone must be robust and intelligently designed — because in high-performance environments, the chain is only as strong as its weakest link. Special Note on Frame Rate & Network Design: If 60fps is required at each workstation, each appliance must be provisioned with a dedicated 1 GigE connection per video channel. This may require dual network connections per device. To conserve GigE ports, drops, and power, limiting workstations to 38fps may be a practical alternative.
