    摘要: A storage system has a plurality of flash packages, and a storage controller for receiving a write request from a host and sending a write-data write request based on data conforming to this write request to a write-destination flash package. A virtual capacity, which is larger than the physical capacity of the flash package, is defined in the storage controller. The storage system compresses the write data, and writes the compressed write data to the write-destination flash chip.

    摘要: A storage system comprises a plurality of flash packages comprising a plurality of flash chips, and a storage controller for receiving a first write request from a higher-level apparatus and sending a second write request of write data based on data conforming to this first write request to a write-destination flash package, and demonstrates a capacity virtualization function for causing a storage capacity to appear larger than an actual storage capacity for the higher-level apparatus, and for configuring a storage space using page units. The storage system generates a second VOL (logical volume) based on a first VOL, manages a plurality of VOLs comprising the first VOL and one or more second VOLs generated based on the first VOL as a VOL group, and allocates the same page to areas of the same address of the plurality of VOLs configuring the VOL group.

    摘要: A SAN manager acquires configuration information from devices constituting a SAN and produces a corresponding relationship between a host computer and a virtual volume (virtual volume mapping) and a corresponding relationship between the host computer and a real volume (real volume mapping). Based on those pieces of mapping information, the SAN manager outputs a corresponding relationship between virtual and real volumes. Meanwhile, the failure notification messages received from the in-SAN devices are construed to detect and output an influence of the failure upon the access to a real or virtual volume. Furthermore, when receiving a plurality of failure notifications from the devices connected to the SAN, the plurality of failure notifications are outputted with an association based on the corresponding relationship between real and virtual volumes.
