Abstract

Each switch blade receives, from a CPU server serving as a migration destination to which a VM to be migrated is migrated, a setting request of port profile information corresponding to the VM. Then, each switch blade determines whether a VSI ID included in the received setting request is stored in a storage unit that stores therein the VSI ID identifying the VM. Subsequently, each switch blade executes processing according to the setting request when determining that the received VSI ID is stored in the storage unit. Furthermore, when determining that the received VSI ID is not stored in the storage unit, each switch blade forwards the setting request to an external switch that is an upper-level data relay device connected to the CPU server serving as the migration destination through the corresponding switch blade.

Claims

1. A computer-readable recording medium having stored therein a profile processing program causing a computer to execute a process comprising:

receiving, from a migration destination server to which a virtual machine to be migrated is migrated, a setting request of port profile information corresponding to the virtual machine;

determining whether, in a storage unit storing therein a virtual machine identifier identifying the virtual machine, the virtual machine identifier included in the received setting request is stored;

executing a setting process of port profile information according to the setting request when it is determined that the received virtual machine identifier is stored in the storage unit; and

forwarding the setting request to a data relay device connected to the migration destination server through the computer when it is determined that the received virtual machine identifier is not stored in the storage unit.

2. The computer-readable recording medium according to claim 1, wherein the process further comprises:

deleting the port profile information stored in the storage unit in association with the virtual machine identifier included in a deletion request, when the deletion request of the port profile information corresponding to the virtual machine is received from a migration source server on which the virtual machine is running in the case that it is determined that the received virtual machine identifier is stored in the storage unit.

3. The computer-readable recording medium according to claim 1, wherein the determining includes determining, when the received setting request is a PRE-ASSOC message of a VSI (Virtual Station Interface) discovery protocol, whether the virtual machine identifier included in the PRE-ASSOC message is stored in the storage unit, and forwarding an ASSOC message of the VSI discovery protocol to the data relay device without performing the determination of whether the virtual machine identifier is stored, the ASSOC message being received after it is determined that the virtual machine identifier included in the PRE-ASSOC message is not stored in the storage unit.

4. The computer-readable recording medium according to claim 1, wherein the process further comprises:

converting, when a notification that the server on which the virtual machine is running operates as a VEPA Virtual Ethernet Port Aggregator) for controlling even communication between virtual machines in the server through an external data relay device is received from the server, a notified operation mode information of the server into a VEB (Virtual Ethernet Bridge) for controlling the communication between the virtual machines in the server within the server, and

transmitting a notification that the server operates as the VEB to the data relay device operating as the VEB.

5. A computer-readable recording medium having stored therein a profile processing program causing a computer to execute a process comprising:

receiving, from a migration source server on which a virtual machine to be migrated is running, a deletion request of port profile information corresponding to the virtual machine;

determining whether, in a storage unit storing therein a virtual machine identifier identifying the virtual machine, the virtual machine identifier included in the received deletion request is stored;

deleting port profile information stored in the storage unit in association with the virtual machine identifier when it is determined that the received virtual machine identifier is stored in the storage unit; and

forwarding the deletion request to a data relay device connected to the migration source server through the computer or destroying the deletion request when it is determined that the received virtual machine identifier is not stored in the storage unit.

6. The computer-readable recording medium according to claim 5, wherein the process further comprises:

converting, when a notification that the server on which the virtual machine is running operates as a VEPA Virtual Ethernet Port Aggregator) for controlling even communication between virtual machines in the server through an external data relay device is received from the server, a notified operation mode information of the server into a VEB (Virtual Ethernet Bridge) for controlling the communication between the virtual machines in the server within the server, and

transmitting a notification that the server operates as the VEB to the data relay device operating as the VEB.

7. A data relay device comprising:

a memory that stores therein a virtual machine identifier identifying a virtual machine running on a server connected to the data relay device; and

a processor coupled to the memory, wherein the processor executes a process including;

receiving, from a migration destination server to which a virtual machine to be migrated is migrated, a setting request of port profile information corresponding to the virtual machine;

determining whether the virtual machine identifier included in the setting request received at the receiving is stored in the memory;

executing a setting process of port profile information according to the setting request when the received virtual machine identifier is stored in the memory; and

forwarding the setting request to an upper-level data relay device connected to the migration destination server through the subject data relay device when the received virtual machine identifier is not stored in the memory.
