IBM announced storage, processing, security, recovery, and data transfer enhancements for z/VSE 6.2 on May 4, 2021. See the corresponding announcement letter for your geography:
- IBM Japan: JP21–0246
- IBM Americas — United States: 221–201
- IBM Europe, Middle East, and Africa: 221–201
- IBM Asia Pacific: AP21–0194
- IBM Americas — Latin America: LP21–0246
- IBM Americas — Canada: A21–0321
Exploitation of the latest IBM System Storage technology
- z/VSE 6.2 supports IBM System Storage TS7700 R5.1.
Exploitation of latest IBM z15 Model T01 and T02 technology
- z/VSE 6.2 provides native support for System Recovery Boost (APAR DY47832). This enables z/VSE to temporarily boost general-purpose central processors (CPs) running at sub-capacity to full capacity in a logical partition (LPAR) during system IPL and shutdown.
- z/VSE 6.2 supports the configurable IBM Crypto Express7S (APAR DY47834), which enables data encryption and Secure Sockets Layer (SSL) acceleration. Elliptic Curve Cryptography (ECC) with a Crypto Express7S can result in accelerated data-in-flight encryption.
The following support is already available with z/VSE 6.2
- z/VSE supports the IBM Fibre Connection (FICON) Express16S+ and FICON Express16SA, as well as the OSA-Express6S/7S family.
- z/VSE supports IBM Fibre Channel Endpoint Security, which provides server authentication and data encryption to protect the integrity and confidentiality of data.
z/VSE support for Transport Layer Security (TLS) 1.3
- TLS 1.3 support (APAR DY30239) is based on VSE Crypto Services/OpenSSL 1.1.1d update (APAR DY47825, in March 2020).
- VSE/POWER PNET SSL supports all available ciphers, including TLS 1.3 (APAR DY47842).
- CICS TS for z/VSE 2.2 supports TLS 1.3 inbound connections (APAR PH28252).
- Interactive User Interface (IUI). Various job skeletons (ICCF library 59) have been updated to include TLS 1.3 cipher suites (APAR PH31756).
- Updates for z/VSE Connector Workstation components for OpenSSL TLS 1.3 support (APAR PH35841).
IBM Data Language/I (DL/I) VSE 1.12.1 support
- DL/I 1.12.1 adds utility improvements for database recovery (APAR PH29950).
VSE/POWER
- PNODE Generation Macro for Networking Support is updated to enable acceleration of data transfer (APAR DY47835).
TCP/IP updates
- IBM TCP/IP for z/VSE 2.2 is updated to the 2.2.8 level (APAR PH27676).
I greatly appreciate your feedback via the z/VSE contact form.
