Abstract

A blade server includes a management blade and managed blade. The management blade manages service data necessary for the service of an application. In the managed blade, the application is activated. The managed blade includes a service data list creation unit and service data list transmission unit. The service data list creation unit creates a service data list representing service data necessary for the service of the application. The service data list transmission unit transmits the service data list created by the service data list creation unit to the management blade. The management blade includes a service data transmission unit. The service data transmission unit transmits, to the managed blade, service data in the service data list transmitted from the service data list transmission unit before the service of the application starts. A service start method for a blade server is also disclosed.

2. A server according to claim 1, wherein said managed blade further comprises service data providing means for providing service data transmitted from said service data transmission means to the application.

3. The blade server according to claim 1, wherein the service data list represents only service data necessary to start application services in the managed blade.

4. The blade server according to claim 3, wherein the service data necessary to start application services comprises at least one of an address of a connection destination, a number of connections necessary to provide services, and data shared with other applications.

5. The blade server according to claim 1, wherein said management blade comprises a service data database configured to store service data necessary to start application services in the managed blade.

6. The blade server according to claim 1, wherein the service data list includes a list of identifiers representing service data necessary to start application services in the managed blade.

7. The blade server according to claim 1, wherein said managed blade is one of a plurality of managed blades, and

wherein said management blade adds, changes, or deletes service data based on a service data list transmitted from each of the plurality of managed blades.

8. The blade server according to claim 1, wherein said service data list creation means creates the service data list of only selected service data provided to the application among service data included in a distribution list.

9. The blade server according to claim 1, wherein said managed blade is one of a plurality of managed blades, and

wherein said storage data list storage means stores service data lists from each of the plurality of managed blades.

10. The blade server according to claim 1, wherein said managed blade is one of a plurality of managed blades, each of said plurality of managed blades comprising a temporary storage means, and

wherein service data managed by the managed blade is expanded before the start of the service of the application in each of said plurality of managed blades.

11. The blade server according to claim 10, wherein, before the start of the service of the application, service data in the temporary storage means of each of said plurality of managed blades is extracted.

12. A blade server comprising:

a management blade which manages service data necessary for a service of an application; and

a managed blade in which the application is activated,

said managed blade comprising;

service data list creation means for creating a service data list representing service data necessary for the service of the application;

service data list transmission means for transmitting the service data list created by said service data list creation means to said management blade; and

service data providing means for providing service data transmitted from said service data transmission means to the application, and

said management blade comprising service data transmission means for transmitting, to said managed blade, service data in the service data list transmitted from said service data list transmission means before the service of the application starts,

wherein when service data which becomes necessary upon changing service data necessary for the service of the application is absent in service data transmitted from said service data transmission means, said service data providing means requests the absent service data of said management blade,

said service data transmission means transmits the service data requested by said service data providing means to said service data providing means, and

said service data list creation means creates a service data list on the basis of changed service data provided from said service data providing means to the application.

13. A blade server comprising:

a management blade which manages service data necessary for a service of an application; and

a managed blade in which the application is activated,

said managed blade comprising;

service data list creation means for creating a service data list representing service data necessary for the service of the application;

service data list transmission means for transmitting the service data list created by said service data list creation means to said management blade; and

service data providing means for providing service data transmitted from said service data transmission means to the application, and

said management blade comprising service data transmission means for transmitting, to said managed blade, service data in the service data list transmitted from said service data list transmission means before the service of the application starts,

wherein when service data which becomes unnecessary upon changing service data necessary for the service of the application exists in service data transmitted from said service data transmission means, said service data providing means extracts only necessary service data from the service data transmitted from said service data transmission means, and provided the necessary service data to the application, and

wherein said service data list creation means creates a service data list on the basis of changed service data provided from said service data providing means to the application.

14. A service start method for a blade server, comprising:

creating a service data list representing service data provided to an application after service of the application starts;

transmitting the service data list from the managed blade to a management blade which manages service data;

storing, on the management blade, the service data list transmitted from the managed blade;

transmitting, from the management blade to the managed blade, service data in the service data list stored in the management blade before the management blade starts and read out after said management blade starts; and

starting the service of the application using the service data transmitted to the managed blade.

15. A method according to claim 14, wherein said starting the service of the application comprises providing the application with service data transmitted to the managed blade.

16. A service start method for a blade server comprising:

creating a service data list representing service data necessary for a service of an application in a managed blade in which the application is activated;

transmitting the service data list from the managed blade to a management blade which manages service data;

transmitting, from the management blade to the managed blade, service data in the service data list transmitted to the management blade before the service of the application starts;

starting the service of the application using the service data transmitted to the managed blade;

when service data which becomes necessary upon changing service data necessary for the service of the application is absent in service data transmitted to the managed blade, causing the managed blade to request the absent service data of the management blade;

transmitting the service data requested by the managed blade from the management blade to the managed blade;
