Computer resource allocating method
First Claim
1. A computer resource allocating method, for allocating servers to each user in a computer system having a plurality of servers interconnected by a Local Area Network (LAN), connected externally to the Internet, connected to a storage and a storage network, and processing a request of a plurality of users, comprising:
- configuring, for each user, a VLAN related to connection to servers allocated to the user and connection between the servers;
monitoring a load of each of the servers;
when making an allocation change of said servers of said user according to the monitoring result of said load, making a dynamic change of the VLAN of the user who changes allocation so that a computer allocated to each user is always included into the VLAN of the user;
configuring a VPN connecting the exit of a user and the entry of said computer system via a carrier on said Internet to each user;
monitoring at least a network load of the VPN configured for each user at the entry of said computer system;
making a change of the VPN configuration so as to change a network bandwidth according to the monitoring result of said load;
configuring zoning for each user by said storage network;
making an allocation of a storage access bandwidth resource to each user;
dynamically changing the storage network bandwidth and LUN access priority according to a load of the storage network of each user; and
wherein when a load to the network and server with respect to the resource divided to a user is increased, a change is made in the order of the resource allocation of the storage network part, the VLAN part configuration and the VPN part configuration.

Abstract
When a load of a user is fluctuated, a data center dynamically changes resource allocation to the user according to the load and holds security for each user.
A control program on a data center managing server creates a VLAN configuration table so as to allocate a user-dedicated VLAN including plural network switches for each user company, thereby configuring the ports of a load balancer and network switches allocated to a user to the user-dedicated VLAN. A VPN is configured from the user to the data center, whereby a VLAN tagging technique is used to hold security of the user from the user to the data center. The control program compares a user condition setting table created along the service level agreement for each user with the monitoring result of the computer operating state (the CPU utilization history in a VLAN operation table) to dynamically change the computer allocation and VLAN configuration at unsatisfied agreement. Specifically, the VLAN configuration table and the VLAN operation table are changed to change the VLAN configuration in the load balancer and the network switches (in the case of the Web layer). The control program changes the parameter (the sever allocation history in the VLAN operation table) related to charge information based on that.
