Name: The Blade Server is a low-cost server platform with high availability and high density. It is specially designed for special application industries and high-density computer environments.
Principle: Each "Blade" is actually a system motherboard. They can start their own operating systems through a local hard disk, such as Windows NT/2000, Linux, Solaris, and so on, similar to independent servers. In this mode, each motherboard runs its own system and serves different user groups and is not associated with each other. However, you can use system software to assemble these boards into a server cluster. In cluster mode, all the mainboards can be connected to provide a high-speed network environment, and resources can be shared to serve the same user group. Insert a new "Blade" into the cluster to improve overall performance. Because each "Blade" is hot-swappable, the system can be easily replaced and the maintenance time can be minimized. It is worth mentioning that the system configuration can be achieved through a set of smart KVM and 9 or 10 CPU boards with hard disks. The CPU can be configured as different subsystems. Servers in a rack can share a set of optical drives, soft drives, keyboards, displays, and mouse with the new Smart KVM Conversion Board to access multiple servers, this allows you to easily upgrade, maintain, and access files on the server.
