Computer system, control apparatus, storage system and computer device

A storage system comprising:

• a plurality of ports which receive data from at least one server and include at least one first port and at least one second port;
• a cache memory temporarily storing data received at the plurality of ports;
• a plurality of processors which control to transfer data received at the plurality of ports and include at least one first processor and at least one second processor;
• a plurality of disks which store data received at the plurality of ports and include a first disk assigned to a first virtual storage system and a second disk assigned to a second virtual storage system;
• wherein a number of the first ports, a first capacity of the cache memory, and a number of the first processors which are assigned to the first virtual storage system are determined based on a first performance;
• wherein a number of the second ports, second capacity of the cache memory and a number of second processors which are assigned to the second virtual storage system are determined based on a second performance.
