Traditional data centres with racks and racks of servers have primarily used high- density KVM switch solutions which take up one to two units of rack space and allow a connection to many servers.
These solutions are tried and true and will continue to be used in situations where high-density servers reside. However, these systems usually require a capital investment for the hardware and often require dedicated management software which, in some cases, also requires dedicated servers to run the software even to the extent that multiple software and server licenses are required for systems on different subnets.
These solutions do not offer the flexibility and scalability needed for the changing landscape of distributed infrastructures. The trend toward distributed environments with many servers deployed throughout the enterprise on different floors and extending outwards to remote branches requires a new way of thinking.
Creative solutions for leveraging the Internet to access servers without the need to purchase high-density appliances or surrender to expensive software license contracts are now a requirement. Determining the right solution greatly depends on the type of environment, the direction of the IT organization, and the underlying need for flexibility and scalability.
For many organizations, a co-existence of high-density and distributed KVM will be the solution where flexibility and scalability are needed to augment existing high-density systems. For the growing trend of distributed computing and organizations with larger remote branch and campus environments, this new paradigm of distributed KVM with all its benefits will take the lead.
