Allocating Storage Capacity to New Servers 21.3

Allocating storage capacity to new servers consists in identifying which storage pool from which storage system is best suited to host the storage capacity required. To identify these storage pools, administrators need to follow these steps:

• • Listing the storage systems that meet allocation requirements
  • Verifying the storage systems bandwidth

Listing the storage systems that 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. List the storage systems that meet your allocation requirements. You can for example apply a filter on the Available Capacity column to only display the storage systems for which more than 5 TB are available:
   1. Click the Available Capacity column
   2. From the pull-down list, select greater than.
   3. Type the value required in Terabytes.
   4. Click Filter.

Once the storage systems matching your search criteria have been displayed, you can verify the storage systems’ bandwidth and the number of ports available.

Verifying the storage systems bandwidth

Verifying the storage systems bandwidth is an essential step that will help administrators choose the storage system that better meets their allocation requirements. To perform this operation, administrators must check the bandwidth utilization and the number of ports available for each storage system.

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. Show the Number of Ports column:
   1. Click  and select Show/Hide Columns.
   2. Check the Number of Ports box.
   3. Click Save.
3. Verify the Bandwidth Utilization of each storage system. If the value is:
   1. low, the storage system can be used to allocate storage capacity to new servers
   2. high, check the number of ports currently available to know if additional ports can be added.

The most relevant storage system is now identified. You can now proceed to the next step, i.e choosing a storage pool according to its pool type and its available capacity.
