Description:	z/VM is a proprietary, hypervisor based virtualization strategy specific to International Business Machines (IBM) System z mainframe computers. Server/mainframe virtualization is the abstraction of physical resources that permits the creation of multiple isolated virtual environments. These environments are sometimes referred to as virtual private servers, guests, instances, containers or emulations. The IBM z/VM Single System Image (VMSSI) is included with z/VM. IBM VMSSI enhances the z/VM systems management, communications, disk management, device mapping, virtual machine definition management, installation, and service functions to enable up to four z/VM systems to share and coordinate resources within a single system image (SSI) cluster. The TRM decisions in this entry only apply to technologies and versions owned, operated, managed, patched, and version-controlled by VA. This includes technologies deployed as software installations on VMs within VA-controlled cloud environments (e.g., VA Enterprise Cloud (VAEC)). Cloud services provided by the VAEC, which are listed in the VAEC Service Catalog, and those controlled and managed by an external Cloud Service Provider (i.e., SaaS) are not in the purview of the TRM. For more information on the use of cloud services and cloud-based products within VA, including VA private clouds, please see the Enterprise Cloud Solutions Office (ECSO) Portal at: https://dvagov.sharepoint.com/sites/OITECSO
Technology/Standard Usage Requirements:	Users must ensure their use of this technology/standard is consistent with VA policies and standards, including, but not limited to, VA Handbooks 6102 and 6500; VA Directives 6004, 6513, and 6517; and National Institute of Standards and Technology (NIST) standards, including Federal Information Processing Standards (FIPS). Users must ensure sensitive data is properly protected in compliance with all VA regulations. Prior to use of this technology, users should check with their supervisor, Information Security Officer (ISO), Facility Chief Information Officer (CIO), or local Office of Information and Technology (OI&T) representative to ensure that all actions are consistent with current VA policies and procedures prior to implementation.
Section 508 Information:	This technology has not been assessed by the Section 508 Office. The Implementer of this technology has the responsibility to ensure the version deployed is 508-compliant. Section 508 compliance may be reviewed by the Section 508 Office and appropriate remedial action required if necessary. For additional information or assistance regarding Section 508, please contact the Section 508 Office at Section508@va.gov.

The VA Decision Matrix displays the current and future VA IT position regarding different releases of a TRM entry. These decisions are based upon the best information available as of the most current date. The consumer of this information has the responsibility to consult the organizations responsible for the desktop, testing, and/or production environments to ensure that the target version of the technology will be supported. Any major.minor version that is not listed in the VA Decision Matrix is considered unapproved for use.

Legend:

White	Approved: The technology/standard has been approved for use.
Yellow	Approved w/Constraints: The technology/standard can be used within the specified constraints located below the decision matrix in the footnote[1] and on the General tab.
Gray	Unapproved: This technology or standard can be used only if a POA&M review is conducted and signed by the Authorizing Official Designated Representative (AODR) as designated by the Authorizing Official (AO) or designee and based upon a recommendation from the POA&M Compliance Enforcement, has been granted to the project team or organization that wishes to use the technology.
Orange	Divest: VA has decided to divest itself on the use of the technology/standard. As a result, all projects currently utilizing the technology/standard must plan to eliminate their use of the technology/standard. Additional information on when the entry is projected to become unapproved may be found on the Decision tab for the specific entry.
Black	Prohibited: The technology/standard is not (currently) permitted to be used under any circumstances.
Blue	Planning/Evaluation Constraint:The period of time this technology is currently being evaluated, reviewed, and tested in controlled environments. Use of this technology is strictly controlled and not available for use within the general population. If a customer would like to use this technology, please work with your local or Regional OI&T office and contact the appropriate evaluation office displayed in the notes below the decision matrix. The Local or Regional OI&T office should submit an inquiry to the TRM if they require further assistance or if the evaluating office is not listed in the notes below.

Release/Version Information:

VA decisions for specific versions may include a ‘.x’ wildcard, which denotes a decision that pertains to a range of multiple versions.

For example, a technology approved with a decision for 7.x would cover any version of 7.(Anything) - 7.(Anything). However, a 7.4.x decision would cover any version of 7.4.(Anything), but would not cover any version of 7.5.x or 7.6.x on the TRM.

VA decisions for specific versions may include ‘+’ symbols; which denotes that the decision for the version specified also includes versions greater than what is specified but is not to exceed or affect previous decimal places.

For example, a technology approved with a decision for 12.6.4+ would cover any version that is greater than 12.6.4, but would not exceed the .6 decimal ie: 12.6.401 is ok, 12.6.5 is ok, 12.6.9 is ok, however 12.7.0 or 13.0 is not.
