VAAI Test Framework:

Testing a Target:

  • Test any “VAAI Target Implementation”
  • Check for compliance with VAAI specifications
  • Build automated regression test suite using scripting feature
  • Calsoft’s iSCSI test suite allows testing a particular target device (or emulator) for conformance to VAAI command
  • Calsoft’s VAAI test framework allows testing a particular target device on FC path

Testing an Initiator:

  • Storage Emulator is Calsoft’s proprietary product which emulates a SAN target. It is capable of exporting VAAI enabled SCSI target/LUNs
  • Storage Emulator will enable users to verify the correctness of initiator as it maintains a history of all the SCSI CDBS that it receives
  • Error Injection on VAAI CDBS will enable testing error path of the initiator
  • Storage Emulator provide tools to look into the file back LUNs and verify the correctness of the results of VAAI commands
