In order to implement a backend network that enables SSDs to be shared among controllers in a small number of stages and that is capable of mounting a number of HDDs, and to enable an increase in storage performance, in a backend network topology, controllers (102, 152) and enclosure expanders are connected by top expanders (110, 160), and the top expanders (110, 160) are connected by a central expander (140). Expanders (119, 120, 121) for connecting SSDs to the top expanders (110) are connected in parallel to each other. Expanders (169, 170, 171) for connecting SSDs to the top expanders (160) are connected in parallel to each other. Expanders (122, 123, 124) for connecting HDDs to the top expanders (110) are connected in series. Expanders (172, 173, 174) for connecting HDDs to the top expanders (160) are connected in series. |
