Abstract

An apparatus includes a queue that stores an instruction instructing a migration process between a first storing device and a second storing device having lower speed; and a processor configured to determine target data for the migration process, store an instruction for the target data into the queue, remove, from the queue, prior to storing of an instruction for first target data determined at a first timing, a second instruction as a removing target, the second instruction instructing migration from the second to first storing device and being determined at a second timing before the first timing, read an instruction from the queue, and control execution of the migration process according to the instruction read from the queue. Target data for an instruction instructing migration from the second to first storing device is data undergoing access concentration in the first storing device or data predicted to undergo access concentration.

Dependent claims

An information processing apparatus comprising:

a queue that stores a migration instruction that instructs a migration process, the migration process migrating data between a first storing device and a second storing device having an access speed lower than that the first storing device;
and
a processor coupled to the queue, wherein
the processor is configured to
determine target data for the migration process,
store a migration instruction for the target data into the queue,
remove, from the queue, prior to storing of a migration instruction for first target data determined at a first timing, a second migration instruction as a removing target among one or more migration instructions stored in the queue, the second migration instruction instructing migration from the second storing device to the first storing device, the second migration instruction being determined at a second timing before the first timing,
read a migration instruction from the queue, and
control execution of the migration process according to the migration instruction read from the queue;
and
wherein target data for a migration instruction instructing migration from the second storing device to the first storing device is one of data undergoing access concentration in the first storing device and data predicted to undergo access concentration.

A non-transitory computer-readable recording medium having stored therein an information processing program that causes a computer to execute a process comprising:

determining target data for a migration process, the migration process migrating data between a first storing device and a second storing device having an access speed lower than that the first storing device,
storing a migration instruction for the target data determined at a first timing into a queue,
removing, from the queue a second migration instruction as a removing target among one or more migration instructions stored in the queue, the second migration instruction instructing migration from the second storing device to the first storing device, the second migration instruction being determined at a second timing before the first timing,
reading a migration instruction from the queue, and
controlling execution of the migration process according to the migration instruction read from the queue;
and
wherein target data for a migration instruction instructing migration from the second storing device to the first storing device is one of data undergoing access concentration in the first storing device and data predicted to undergo access concentration.
