Suggest changes
You can use the ListProtectionDomainLevels

Tolerance levels indicate the cluster's ability to continue reading and writing data in the event of a failure, and resiliency levels indicate the storage cluster's ability to automatically heal itself from one or more failures.
Parameter
This method has no input parameter.
Return values
This method has the following return values:
Name | Description | Type |
---|---|---|
protectionDomainLevels |
A list of the different protection domain levels, where each supplies the storage cluster's tolerance and resiliency information. |
Request example
Requests for this method are similar to the following example:
{ "method": "ListProtectionDomainLevels", "params": {}, "id" : 1 }
Response example
This method returns a response similar to the following example:
{ "id": 1, "result": { "protectionDomainLevels": [ { "protectionDomainType": "node", "resiliency": { "protectionSchemeResiliencies": [ { "protectionScheme": "doubleHelix", "sustainableFailuresForBlockData": 0, "sustainableFailuresForMetadata": 1 } ], "singleFailureThresholdBytesForBlockData": 0, "sustainableFailuresForEnsemble": 1 }, "tolerance": { "protectionSchemeTolerances": [ { "protectionScheme": "doubleHelix", "sustainableFailuresForBlockData": 0, "sustainableFailuresForMetadata": 1 } ], "sustainableFailuresForEnsemble": 1 } }, { "protectionDomainType": "chassis", "resiliency": { "protectionSchemeResiliencies": [ { "protectionScheme": "doubleHelix", "sustainableFailuresForBlockData": 0, "sustainableFailuresForMetadata": 1 } ], "singleFailureThresholdBytesForBlockData": 0, "sustainableFailuresForEnsemble": 1 }, "tolerance": { "protectionSchemeTolerances": [ { "protectionScheme": "doubleHelix", "sustainableFailuresForBlockData": 0, "sustainableFailuresForMetadata": 1 } ], "sustainableFailuresForEnsemble": 1 } } ] } }
