MTI’s philosophy has been to create “high-availability” systems within its facilities with redundancy layered in to complement the infrastructure. For example, MTI uses multiple voice gateway platforms, each with redundant power supplies, redundant network interface cards, and RAID-5 technology. The redundant power supplies are each connected toredundant UPS systems. The redundant NICs are each connected to redundant internal LANs. The redundant power supplies, NICs, and RAID-5 technology create high-availability, while the use of multiple voice gateway platforms provides high redundancy. This high-availability strategy covers most common “disaster” events, such as a power loss, or a LAN segment failure.
