Q. What is the Storage Work Group?
A. The Storage Work Group is an entity within the Trusted Computing Group. It consists of TCG
member companies with interests in the implementation of the Trusted Computing Group’s
specifications for storage devices. For more information on the Storage Work Group, please refer towww.trustedcomputinggroup.org.

Q. What is the Core Specification?
A. The Core Specification, officially known as TCG Storage Architecture Core Specification,
developed by the Storage Work Group provides a comprehensive definition of TCG-related
functions for a TCG storage device.

Q. What is a Security Subsystem Class (SSC)?
A. The Core Specification can be further broken down in multiple subsets of functionality called Security
Subsystem Classes (SSCs). SSCs explicitly define the minimum acceptable Core Specification
capabilities of a storage device in a specific “class” and potentially expand functionality beyond what isdefined in the Core Specification.

Q. What is the Opal SSC?
A. The Opal SSC specification is predicated on ease of implementation and integration. This SSC
defines the functionality for implementing the Core Specification on storage devices.

Q. What is the Opal family set of SSCs?
A. The Opal family set of SSCs are a collection of SSCs that have been developed based on the Opal
SSC specifications. The Opal family SSCs include Opal, Opalite, Pyrite, and Ruby.

Q. What is the TCG Storage Opal Family Test Cases Specification?
A. The TCG Storage Opal Family Test Cases Specification contains a set of tests that are intended toverify the correct behavior of a storage device implementing one or more of the Opal family SSC

Opal Family Test Cases
Specification FAQSpecifications. These test cases are intended to be used as a basis for the compliance component of
the Storage certification program, which will seek to ensure a high level of interoperability of storage
devices from multiple vendors.

Q. What is the difference between TCG Storage Opal Family Test Cases Specification andprevious TCG Storage Opal Test Cases Specification?
A. The TCG Storage Opal Family Test Cases Specification is defined to cover the test cases for Opalfamily SSCs. This specification covers a larger scope than the previous Opal Test Cases Specification.
The Opal Family Test Cases Specification is intended to replace the previous Opal Test Cases
Specification by expanding the original test cases and adding new test cases for other SSCs in theOpal family.

Q. To which versions of Opal family SSCs does this specification apply?
A. The following SSC specification are covered by the TCG Storage Opal Family Test Cases
specification: TCG Storage Security Subsystem Class: Opal Version 1.00, 2.00, 2.01; Opalite Version
1.00; Pyrite Version 1.00, 2.00; and Ruby Version 1.00.

Q. What is the audience for this specification?
A. The target audience for this Opal Family Test Cases Specification includes system integrators fortrusted storage solutions including security software vendors, manufacturers of Opal Family SSC
storage devices, and compliance test suite vendors.

Q. When will the Storage certification program be available?
A. The TCG Storage certification program has been available since March 2018 for the Opal SSC
devices. Please refer to the storage certification information on the TCG website.
