Data management system for storages
First Claim
1. A data management system for storages, suitable for a system having a host and a plurality of storages connected to a data transfer network, comprising:
- a converter facility for converting a block (unity) of semantically significant data specific to an operating system (OS) on said host into a unity of semantically significant data common to said data transfer network; and
a management facility for managing a readout of said unity of data from one of said storages upon reception of the unit name of said data from said host, said facility being provided apart from said host.

Abstract
Files in various file formats for different operating systems coexist even under the environment where a number of storage devices are connected to a faster data transfer network such as SAN. The storage management so far has been always attained under the control of an operating system of a host.
The present invention provides a SAN-FM server, having a SAN-FS for converting files in a format specific to the operating system into files in a format common to the SAN, for managing files on the storage devices from a SAN-FM to allow to access by a common file among storage devices.

9. A data management system for storages, suitable for a system having a plurality of storages and hosts connected to a data transfer network, comprising:
-
a host having a file system converting files in a file format specific to an operating system into files in a file format common on said data transfer network, and converting files in said common file format on said data transfer network into files in said file format specific to said operating system, and said host updating data in said file format specific to said operating system;
a storage having a file storage area for storing files in a format common to said data transfer network, a virtual space for retaining files that may be transmitted and received to and from said host or another storage and that is in said format common to said data transfer network, as well as a storage controller for asynchronously allocating said file read out from said storage area to said virtual space to transmit to said host said file in said virtual space. - View Dependent Claims (11)
