SMI-S 1.0.0 Release Notes

Currently viewing public documentation. Please login to access the full scope of documentation.

SMI-S is an interface standard for storage management. SMI-S enables both hardware and software interoperability between different vendors’ enterprise storage products and allows vendors to develop to a single standard interface. For more information, see Storage Management Initiative at the Storage Networking Industry Association site.

Release 1.0 of the Pure Storage SMI-S provider is embedded in Purity 4.6.0+ release.

Release Compatibility

  • This release is compatible with Purity releases that support REST API 1.2.  We recommend the latest 4.6.x for this release.

Hardware Requirements

  • This release is supported on FlashArray//M and FA-400 systems.

Software Requirements

  • Purity 4.6 or higher.

SMI-S Specification Support

This release complies with the following:

  • Storage Management Technical Specification, Part 3 Common Profiles Version 1.6.1, Revision 5
  • Storage Management Technical Specification, Part 4 Block Devices Version 1.6.1, Revision 5

Certification Tests

  • Passes the SNIA CTP tests.
  • Passes the System Center Virtual Machine Manager (SCVMM) 2012 R2 with update rollup 8 test on fiber channel.

Known Issues

  • When the array's CPU is under a very high workload, SMI-S clients may experience failures due to timeout. This is because the SMI-S service is running with lower priority than other critical array tasks. 
  • Some instance settings such as indication filters, listeners, and subscriptions maybe lost in the following scenarios:
    • There is settings repository switch due to a controller failover. 
    • The SMI-S service fails unexpectedly and the settings repository is corrupted. 


If the SMI-S provider cannot be added as a storage resource under SCVMM, check the following:

  • Make sure that SMI-S is enabled using the Purity GUI (System > Configuration > SMI-S) or CLI (puresmis command).
  • If the array does not have a valid certificate installed, modify the following registry key on the machine running SCVMM:

    Key name: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Storage Management

    Name: DisableHttpsCommonNameCheck 
    Type: REG_DWORD
    Value: 1

  • On Windows Server 2008R2, the TLS 1.1 protocol should be enabled. Manually add the following registry keys, subkeys, and values:

    Key name: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS 1.1
    Key name: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS

    Name: DisabledByDefault 
    Type: REG_DWORD 
    Value: 0

    Key name: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\SCHANNEL\Protocols\TLS
