A method for managing access of virtual machines executed by a host computer system to storage area networks, the storage area networks connecting the host computer system with storage systems via switches, where the host computer system includes one or more host ports to connect with a switch each, and where one or more port names are assigned to each virtual machine. The method includes, for each storage area network connected with the host computer system, sending the port names of a virtual machine and a target port name as part of a validate access command to the respective switch; and when receiving the validate access command by the switch, the switch returning success information to the sending host computer system in case all received virtual machine port names have access to a target port assigned to the received target port name, otherwise returning a fail information.

Access of virtual machines to storage area networks

Deploying a software service. A defined software service offering is selected from a plurality of defined software service offerings. An instantiation order for deploying the selected defined software service offering on a corresponding computer system is generated. Each defined software service offering comprises a software service definition and at least one defined software policy. One selected from the group consisting of the software service definition, the software policy, and a combination thereof, provides a hardware configuration for the software service, a software configuration for the software service, and a managing policy for the software service. The instantiation order of the software service for execution on the computer system is created based on the hardware configuration, the software configuration and the managing policy.

Method, arrangement, computer program product and data processing program for deploying a software service

Virtual machines in a computer system cluster, or cloud environment, require access to their assigned storage resources connected to the virtual machines via storage area networks (SAN). Such virtual machines may be independent from associated physical servers in the computer system cluster on which they are deployed. These virtual machines may dynamically migrate among assigned physical servers while maintaining access to their connected storage resources both from the source physical server and the target physical server during the migration.

Flexible deployment and migration of virtual machines

Managing virtual network ports on a physical server to provide a virtual server access to a group of storage resources through a network. A storage access group representing a group of storage resources is generated. A virtual server is generated on a hypervisor executed on the physical server. Access to the network is activated for the virtual server. A management console is provided for creating and managing the storage access group providing access to the group of storage resources for the virtual server from one or more physical servers. The management console includes a virtual server management facility and a storage access group facility. The virtual server management facility allows for managing virtual server definitions and activating, deactivating, and migrating virtual servers. The storage access group facility allows for managing virtual network port descriptions, administrating network port names, and creating, activating and deactivating virtual network ports.

Managing virtual network ports

A management system and method that generally allocates a virtual function to a virtual function definition of a virtual server, where the virtual function definition of the virtual server is previously assigned with a unique function identifier, and assigns the unique function identifier to the virtual function in response to the allocating of the virtual function, where the unique function identifier causes a discovery of the virtual function by the virtual server.

Supporting flexible deployment and migration of virtual servers via unique function identifiers

A computer-implemented method, carried out by one or more processors, for policy based virtual resource allocation. In an embodiment, the method includes identifying a number of host resources specified by host resource requirements for a first resource consumer. The method determines if the host resource requirements include a list of host resource pools for the first resource consumer. Responsive to determining that the host resource requirements include the list of host resource pools for the first resource consumer, a first set of eligible host resource pools is identified. An allocation policy may be identified, where the allocation policy includes one or more parameters for allocating host resources. Host resources from the first set of eligible host resource pools are allocated based on the allocation policy.

Policy based virtual resource allocation and allocation adjustment

A method for managing resources in a server environment includes querying a first resource consumer for a list, wherein the list includes at least a first virtual resource and a first host resource. The method queries a host resource pool to determine if the first host resource is present. Responsive to determining the first host resource is present in the host resource pool, the method allocates the first host resource to the first resource consumer. The method sends a request to activate the first virtual resource and the first host resource to a virtual resource provider and a host resource provider, wherein the request to activate the first virtual resource and the first host resource is performed on a single thread. The method determines to prepare one or more virtual resources for activation of one or more allocated host resources.

Resource allocation/de-allocation and activation/deactivation

Assigning a set of port names to storage access paths of virtual machines accessing storage resources via storage area networks is provided. A first computing system cluster that is associated with a set of computing system identifiers is created. A first computing system identifier associated with a first computing system is added to the set of computing system identifiers. The first computing system is disassociated from the first computing system identifier. The first computing system is added to the first computing system cluster.
