摘要: A fault-tolerant storage system is provided. The storage system is composed of a controller having a plurality of processors and other units. When an error occurs in any one of the components in the controller, the storage system cuts off an I/O path of the controller, specifies the failed component in the cutoff status, and invalidates the failed component. After invalidating the failed component, the storage system determines whether it is operable only with the normal components, cancels (releases) the cutoff of the I/O path when it determines that it is operable, and resumes operation by rebooting.

摘要: The time required for starting up drives in a storage device mounted with both hard disk drives and solid state drives is shortened. A storage controller of the storage device identifies the type (HDD/SSD) of the mounted drives before starting up the drives. The storage controller thereafter performs staggered spinup to the HDDs in several batches. After the startup of HDDs is complete, the storage controller collectively starts up the SSDs. The storage controller determines the drive startup processing based on a pre-set drive startup policy such as reduction of the peak current reduction or shortening of the startup time, and the drive type identification result.

摘要: The present invention provides a storage system capable of having a large-scale configuration for maintaining a write access response speed and reliability upon an occurrence of a failed cache and its control method. Plural clusters that control a disk drive connected thereto and have a cache memory are connected to one another through a cross coupling network, and write data in the cache memory of another cluster is mutually made redundant in the cache memories in two clusters that jointly use the same disk drive. When a failure occurs in the cache memory, the cluster that uses the disk drive jointly with the cluster having the cache memory in which the failure occurs performs processing for getting access to the disk drive performed by the cluster having the cache memory in which the failure occurs, and the other normally-operated cluster is caused to perform to only make redundant the write data in the cache memory in its cluster.
