What is a Resource Pool?
A resource pool is a set of resources available for assignment to project tasks. A resource pool can be assigned exclusively to a project or task or shared by several projects. One resource can be part of individual resource lists for multiple projects, or the resource can be part of a single shared resource pool.
A resource pool serves as a centralized set of resources available for assignment to various project tasks. This powerful tool improves efficiency and streamlines resource allocation across multiple projects. As the information is integrated and accessible to all users, you can also quickly identify conflicts between an employee’s tasks on different projects and see how their time is allocated to each project.
In project management and resource management, automation facilitates the creation and use of resource pools. The software allows you to create specific project files for resource information. This makes it much easier to manage information and task assignments.
What is Resource Pooling?
Resource pooling is a key concept in cloud computing and IT resource management. Here is an overview of what resource pooling means:
Resource pooling refers to the practice of grouping computing resources to serve multiple clients or users simultaneously. In this model, physical and virtual resources are dynamically assigned and reassigned according to consumer demands.
Key aspects of resource pooling include:
- Multi-tenant model: Resources are shared among multiple customers or users.
- Dynamic allocation: Resources are assigned and reassigned based on demand, allowing for flexibility and scalability.
- Location independence: Customers don’t know or control the exact location of resources but may be able to specify a location at a higher level (e.g. country or data center).
- Types of resources: Pooled resources can include storage, processing power, memory, and network bandwidth.
- Optimization: Resource pooling aims to maximize advantage and minimize risk for users by efficiently using available resources.
- Virtualization: Often involves virtualizing IT components like servers, storage, and networking to create shared resource pools.
Some benefits of resource pooling include improved cost-effectiveness and operational efficiency and reduced idle time for resources. The ability to serve multiple clients without a dedicated infrastructure for each and the flexibility to scale resources up or down as needed are additional benefits.
Resource pooling is a key feature of cloud computing environments. It lets providers serve many clients better and gives users access to more resources than they could have on their own.
What Are the Different Types of Resource Pools?
There are several types of resource pools used in various IT, project management, and resource management contexts. Here are some examples.
Virtual Environment Resource Pools
1. VM Pools
These pools store VM hosts used for creating new virtual servers. They’re common in virtualization platforms like VMware vSphere.
2. Storage Pools
These contain virtual storage resources such as RAID groups, aggregates, VM file systems, LUNs, FlexVol, and virtual disks.
3. Network Pools
These manage network resources for virtual environments.
4. Address Pools
These manage IP addresses and other network-addressing resources.
Project Management Resource Pools
5. Human Resource Pools
This groups people with similar skills or roles who can be assigned to projects.
6. Equipment Resource Pools
This manages shared equipment or tools that can be allocated to different projects.
7. Cloud Computing Resource Pools
In cloud environments, resource pools often include compute resources (CPU, memory), storage resources, and network bandwidth. These are dynamically allocated to serve multiple clients or applications.
Specialized Resource Pools
8. Server Pools
These contain physical servers used for creating new server instances.
9. Image Pools
These store software images or templates used for deploying new systems.
10. Hierarchical Resource Pools
VMware vSphere allows the creation of hierarchical resource pools such as parent resource pools, child resource pools
11. Sibling resource pools
This structure enables flexible management of CPU and memory resources across multiple levels of the organization. This helps to manage CPU resources.
Resource pools can be made to fit specific company needs. This lets you use and manage different IT resources in different projects, departments, or applications in a way that works well for you.
How to Create a Resource Pool
To create a resource pool, follow these steps:
- Access the management interface for your virtualization platform (e.g. vCenter Server or vSphere Client for VMware or Microsoft).
- Select the parent object for the new resource pool. This could be an ESXi host, an existing resource pool, or a DRS cluster.
- Open the “New Resource Pool” dialog, typically by selecting an option like “Create Resource Pool” or “New Resource Pool”.
- Provide a name for the new resource pool (e.g. “RP-QA” for a QA department pool or pool_name).
- Configure the resource settings:
- CPU resources: Set shares, reservation, and limit
- Memory resources: Set shares, reservation, and limit
- Choose whether to enable scalable shares and permissions if applicable
- For CPU and memory, you can typically select from predefined share levels (High, Normal, Low) or enter a custom value.
- Set reservations to guarantee a minimum amount of CPU or memory.
- Set limits to restrict maximum resource usage if desired.
- Decide whether the reservation should be expandable.
- Click “OK” or “Create” to finalize the resource pool creation.
Remember that resource pools can be nested, allowing you to create hierarchies of resource allocation. For example, you could create separate pools for different departments (e.g. RP-QA and RP-Marketing) and then create child pools within those for specific teams or projects.
When creating multiple resource pools, consider how to distribute resources among them. For example, you might give higher priority to critical departments by allocating more shares. Try troubleshooting before deciding.
Key Features of Resource Pools
Shared Resource Management
Resource pools can be shared among several projects or assigned exclusively to a specific project or task. This flexibility allows organizations to maximize resource utilization and reduce idle time.
Centralized Information
Project management software lets you create resource pools. It puts valuable information in one place, like resource names, calendars, resource units, and cost rate tables. This centralization facilitates easier management of information and task assignments across projects.
Cross-Project Scheduling
One of the primary benefits of a resource pool is the ability to schedule work across multiple projects. This feature allows project managers to:
- Identify conflicts in employee assignments
- Analyze time allocation across different projects
- Optimize resource utilization
Benefits of Using Resource Pools
Here are some benefits you may experience when you use resource pools:
Operational Efficiency
Organizations leverage shared resources to improve cost-effectiveness and operational efficiency. By using a resource pool, companies can reduce bench time, maximize resource utilization, and minimize the need for additional staffing.
Conflict Resolution
Resource pools enable quick identification of conflicts between an employee’s assignments in different projects. This visibility helps project managers make informed decisions and resolve scheduling issues proactively.
Centralized Resource Information
With a shared resource pool, assignment information, cost rates, and availability for all resources are centralized in one location. This consolidation simplifies resource management and improves overall project coordination.
Resource Pool Examples
We have touched on these but let us go a little more in-depth. Catch resource pools in action in the following examples:
- VM Pool: This type of resource pool is specifically designed for storing virtual machine (VM) hosts. It is used when making new servers. It helps you manage and share virtual resources within a virtualization environment, like VMware vSphere.
- Storage Pool: A storage pool consists of various storage resources, including RAID groups, virtual disks, and file systems. This pool lets you organize and manage storage resources. It makes it easier to choose and use storage for different applications and tasks.
- Human Resource Pool: In project management, a human resource pool groups individuals with similar skills or roles. This lets project managers choose team members for different projects based on their skills and availability. This helps them use more resources and complete projects better. This also improves workflow.
These examples illustrate the versatility of resource pools across different domains, including virtualization, resource management, storage management, and project management.
Implementing Resource Pools
To effectively implement a resource pool:
- Set up individual project files containing project-specific resource information
- Create a shared resource pool
- Assign resources from the single resource pool to various projects
- Set notifications to stay up to date with the process
By following these steps, organizations can optimize their project management processes and ensure efficient resource allocation across multiple projects.
Resource Pool: Looking Ahead
A resource pool makes it easier to administer people, or even equipment assigned to tasks, in more than one project file. Using automation enables you to centralize resource information, such as the resource name, calendar, used, resource units, and cost rate tables.
Assignment information, cost rates, and availability for all resources are now centralized in one location. The shared resource pool is then created, and all resources are assigned from the single resource pool.
