  • Publication number: 20100049915
    Abstract: A method and system are described for the use of a high speed storage device to temporarily substitute for a low speed storage device in a computer storage system. Because the change is done behind a virtualization facade, hot swapping of the storage devices is achieved. A record is kept of changes to the high speed storage device during the substitution interval, to update the low speed storage device so that it can resume its responsibilities. The resumption of responsibilities by the low speed storage device is also achieved by hot swapping. The approach makes effective use of a relatively rare resource in the storage system, permitting it to be shared among various applications, as directed by a timesharing engine.
