Planning for additional storage capacity

Administrators are not only asked to assign storage resources but also to plan for both current and future storage requirements. Because under-purchasing and over-purchasing capacity will respectively result in downtimes and wasted storage, both situations must be prevented. Smooth storage administration can only be achieved if administrators can answer the questions below:

With this information, they will be able to guarantee enough remaining space to answer allocation requests as quickly as possible.

When will storage pools be running out of capacity?

  1. Access the Storage Systems page:

    1. Log on to the Helix Continuous Optimization Dashboard.
    2. In the Navigation pane, click Views > Storage > Storage Systems
  2. Click the Pools tab.
  3. Verify the capacity of your storage pools and more especially:
    1. their total space (Capacity metric).
    2. the total space not consumed (Available Capacity metric).
    3. the space actually consumed (Consumed Capacity metric).
  4. Sort the Saturated Risk column to view the Saturated and No Risk storage pools

You will then be able to take the necessary actions at the right time to ensure that storage pools will never run out of capacity.

By how much the capacity of their storage pools must be extended to meet allocation requirements?

  1. Access the Storage Systems page:
    1. Log on to the Helix Continuous Optimization Dashboard.
    2. In the Navigation pane, click Views > Storage > Storage Systems
  2. Click the Pools tab.
  3. Click the storage pool of your choice to display its details and check its Capacity trend.

After completing the above steps, you should know exactly by how much the capacity of your storage pool needs to be extended.

Are there enough unused disks in the storage systems to extend the capacity of the existing storage pools?

Before purchasing additional space, administrators can also check if there are unused disks in their storage systems that could still be used to extend the capacity of the existing storage pools. To perform this verification:

  1. Access the Storage Systems page:

    1. Log on to the Helix Continuous Optimization Dashboard.
    2. In the Navigation pane, click Capacity > Storage > Storage Systems
       
  2. Click the storage system for which you wish to check the number of unused disks.
  3. In the Capacity Summary graph, check the value of the Available Capacity for Storage Pools metric.

You now know which disks can be used to extend the capacity of your storage pools.
