A resource pool is a bundle of all resources of the same type (such as virtual servers, storage, networks, or images).
Introducing resource pools has the following benefits.
Until now, it was necessary to purchase new resources such as servers, storage, and networks every time a business activity was expanded or a new business activity was introduced. This involves a lot of effort, first to get approval for the purchase, then to arrange to purchase the resources, then to create environments, and so on. By introducing this product, servers can be created by simply pulling the necessary resources out of resource pools. This eliminates the need for the time and effort discussed above, and allows infrastructure environments to be created and operated according to plan.
Resource pool management is a function for utilizing resources effectively without waste. There are several types of resource pool, as shown below. Pre-registering the resources controlled by this product in resource pools makes it possible to create servers (including storage and networks) rapidly by pulling out the appropriate resources from resource pools in response to user requests. If a server is no longer required, the resources can be released and set aside for reuse.
Multiple resource pools can be created, according to the operation requirements (such as separate resource pools for different hardware types, security levels or resource management units). If a resource pool runs out of resources, new resources can be added or resources can be moved from other resource pools.
Type of resource pool | Overview |
|---|---|
VM | VM pools are resource pools for storing the VM hosts that are used when new servers (VMs) are created. With VM pools that include a mix of different server virtualization software products, if you specify a VM type when creating an L-Server, the appropriate VM host will be selected to create the L-Server. In environments in which multiple cluster groups have been registered in the same VM pool, it is only possible to migrate the L-Server between VM hosts belonging to the same cluster. |
Server | Server pools are resource pools for storing the physical servers that are used when new servers are created. Note Although displayed as a resource pool, this resource pool type cannot be used in Cloud Infrastructure Management Software. |
Storage | Manages virtual storage resources and disk resources in this product. 'Virtual storage resources' refers to the file system that is used for VM guests which are controlled by VM management products such as RAID groups, which themselves are controlled by the storage management products. These can be managed as virtual storage resources using a common operation. 'Disk resources' refers to the disk that is allocated to the server. In the case of the VM guest, this is equivalent to the virtual disk. In this product, disk resources are allocated to the L-Server using the following methods:
The following virtual storage resources are stored in the storage pool:

Network | Network pools are resource pools for storing network resources that define the networks to be connected to servers. Refer to Section 1.2.6, "Simplifying Network Settings" in the "ServerView Resource Orchestrator User's Guide" for details on network resources. |
Address | The following resources are stored in this type of resource pool.
