Abstract

In a method for managing redundant arrays of independent disks (RAID) cards and a server for executing the method, the server calculates a theoretical percentage of a load of each RAID card according to a number of the RAID cards, and loads an actual percentage of the load of each RAID card through a multi input output (MIO) interface, and detects peripheral component interconnect-express (PCI-E) bandwidth of each RAID card. When the load of each RAID card is unbalanced or the PCI-E bandwidth of the RAID card is saturated, the server transfers the load from a RAID card having a greater actual percentage of the load into a RAID card having a less actual percentage of the load, and transfers the load from a RAID card whose PCI-E bandwidth is saturated into a RAID card whose PCI-E bandwidth is unsaturated according to differential signals through the MIO interface.
