NVIDIA SHARP REST API

Note

SHARPv2 must be running (enable_SHARP = true) and the NVIDIA Scalable Hierarchical Aggregation and Reduction Protocol (SHARP)™ allocation parameter must be enabled (enable_SHARP_alloction = true) for this API to trigger resource (GUID) allocations and deallocations within SHARP.

NVIDIA SHARP reservation REST APIs support the following operations:

Get All Reservations

  • Description – Retrieves all SHARP reservations

  • Request URL – GET /ufmRest/app/sharp/allocate_resources

  • Request Content-Type – Application/json

  • Response

    Copy
    Copied!

  • Status Codes

    • 200 – OK

    • 400 – BAD_REQUEST

Create a New SHARP Reservation

Note

The following API is replacing the deprecated SHARP API presented in earlier versions of this UFM Enterprise REST API Guide.

  • Description – Creates a new SHARP reservation. By default, the SHARP blocking API is called, which entails sending the reservation request to SHARP and awaiting the response (success or fail). To revert to the previous behavior of using the non-blocking API, set the "blocking" parameter in the API to false. If the partial allocation parameter is set to false, the SHARP allocation request will not succeed in the event that even a single node is absent in the fabric. By default, this parameter is set to true.

  • Example of a false partial allocation: Request URL – POST /ufmRest/app/sharp/resources?partially_alloc=false

  • Example of calling a non-blocking API: Request URL – POST /ufmRest/app/sharp/resources?blocking=false

  • Request Content-Type – Application/json

  • Status Codes

    • 202 – ACCEPTED (All nodes were added successfully to created allocation)

    • 206 – PARTIAL (Not all nodes were added to created allocation because they are not found in the fabric)

    • 200 - OK (All nodes were added successfully to the created allocation and the SHARP blocking API is called)

    • 400 – BAD_REQUEST

  • Request Data

Delete SHARP Reservation

Note

The following API is replacing the deprecated SHARP API presented in earlier versions of the UFM Enterprise REST API Guide.

  • Description - Deletes SHARP Allocation. By default, the SHARP blocking API is called to delete SHARP reservation.

  • Example of calling delete allocation using SHARP blocking API: Request URL - DELETE /ufmRest/app/sharp/resources/<app_id>

  • Example of calling delete allocation using SHARP non-blocking API: Request URL - DELETE /ufmRest/app/sharp/resources/<app_id>?blocking=false

Update SHARP Reservation

Note

The following API is replacing the deprecated SHARP API presented in earlier versions of this UFM Enterprise REST API Guide.

  • Description – Updates SHARP Allocation. By default, the update SHARP blocking API is called, which entails sending the update reservation request to SHARP and awaiting the response (success or fail). To revert to the previous behavior of using the non-blocking API, set the "blocking" parameter in the API to false. If the partial allocation parameter is set to false, the SHARP allocation request will not succeed in the event that even a single node is absent in the fabric. By default, this parameter is set to true.

  • Example of a false partial allocation: Request URL – PUT /ufmRest/app/sharp/resources/<app_id>?partially_alloc=false

  • Example of calling a non-blocking API: Request URL – PUT /ufmRest/app/sharp/resources<app_id>?blocking=false

  • Request Content-Type – Application/json

  • Status Codes

    • 202 – ACCEPTED (All nodes were updated successfully to SHARP allocation)

    • 206 – PARTIAL (Not all nodes were updated to SHARP allocation because they are not found in the fabric)

    • 200 - OK (All nodes were updated successfully to the SHARP allocation and the SHARP blocking API is called)

    • 400 – BAD_REQUEST

  • Body Examples:

    • Update SHARP allocation by sending hosts_names:
