  • Publication number: 20200356471
    Abstract: A storage system monitors the first access frequency of occurrence which is the access frequency of occurrence from a host device during a first period, and the second access frequency of occurrence which is the access frequency of occurrence from a host device during a second period shorter than the first period. Along with performing data relocation among the tiers (levels) in the first period cycle based on the first access frequency of occurrence, the storage system performs a decision whether or not to perform a second relocation based on the first access frequency of occurrence and the second access frequency of occurrence, synchronously with access from a host device. Here the threshold value utilized in a decision on whether or not to perform the first relocation is different from the threshold value utilized in a decision on whether or not to perform the second relocation.

  • Patent number: 10789196
    Abstract: Efficient communication between storage controllers can be performed. A storage system includes one or more backend switches that connect a first processor, a second processor, and one or more storage devices to each other. Each backend switch identifies a destination of a frame by referring to the frame received from the first processor. In a case where the destination of the frame is the second processor, each backend switch translates a first address, included in the frame, for specifying a location on the second memory in an address space of the first processor, into a second address for specifying the location on the second memory in an address space of the second processor, and transfers the frame including the second address to the second storage controller.
