A double-walled container including: an outer layer body; an inner layer body, which is provided in a pinched-off portion and which passes through the outer layer body. The pinched-off portion is formed in a bottom due to pinch-off using a splittable mold in blow molding. The bottom is provided, on an inner side in a radial direction of an outer edge portion thereof, which serves as a ground-contacting surface, with a substantially cross-shaped recess, which is concave toward a mouth. The recess is configured by a first-direction recess portion, which extends along an extending direction of the slit, and a second-direction recess portion, which intersects with the first-direction recess portion. The slit is provided in a region in which the first-direction recess portion and the second-direction recess portion intersect with each other.

Double-walled container

Each transfer route includes an FE I/F out of a plurality of FE I/Fs, a BE I/F out of a plurality of BE I/Fs, at least one memory out of one or more memories, and at least one processor out of one or more processors. I/O target data is transferred via a target transfer route including an FE I/F that has received an I/O request out of a plurality of transfer routes. A processor in the target transfer route generates routing information representing a physical device included in the target transfer route, and transmits a transfer indication including the routing information to at least one of the FE I/F and BE I/F in the target transfer route. In response to the transfer indication, at least one of the FE I/F and BE I/F in the target transfer route adds, to the I/O target data, a guarantee code.

Identifying a physical device in which a fault has occurred in a storage system

Each of SAS expanders ('expander(s)' hereinafter) has a switch device for switching whether to bypass the expander in each communication path or not. Of the plurality of switch devices, an actual connection destination of a switch device bypassing the expander is a switch device in a upper-level and/or a lower-level of the switch device. Of the plurality of switch devices, an actual connection destination of a switch device that does not bypass an expander is the expander.
