» OpenVMS 7.3-1 Announcement information
OpenVMS Alpha V7.3-1 delivers enhanced OpenVMS Storage Area Network
offerings, improved system availability, significant improvements in I/O and
SMP performance, enhanced security, expanded ability to port UNIX applications
to OpenVMS and an enhanced TCP/IP product for extended interoperability and
New features and enhancements to the operating system include:
Extended failover capability to served devices in an OpenVMS cluster
environment -- extends device failover to served devices, as well as directly
attached devices. This eliminates single points of failure for served devices.
Fibre channel performance enhancements -- new features such as distributed
interrupts and interrupt coalescing, as well as reductions in I/O Lock8 usage,
providing two times the I/O throughput on fibre channel over the previous
Multipath tapes on fibre channel -- provides multipath capabilities for fibre
channel tapes to reduce downtime.
Significant Performance improvements for applications running on SMP systems.
Expanded security with more authentication options -- integrated Kerberos
support and simplified authentication through the new SYS$ACM interface.
Industry standard encryption options -- OpenSSL (Secure Socket Layer) and the
Common Data Security Architecture (CDSA) provide the cryptographic tools and
utilities needed to deploy secure applications.
UNIX portability enhancements -- enhancements in the CRTL and file system make
porting UNIX applications to OpenVMS much easier.
Secure Web Browser (CSWB) -- the supported browser for OpenVMS
AlphaServer systems based on Mozilla, an open-source Web browser designed for
standards compliance, performance and portability.
Graphic Configuration Manager (GCM) for OpenVMS -- a portable, client/server
application that provides a visual means of viewing and controlling the
configuration of partitioned AlphaServer systems running OpenVMS which helps
overall management of the partitions.
Some competitive advantages of the OpenVMS environment include: OpenVMS Galaxy
which provides dynamic reconfiguration without rebooting; significant
flexibility with partitioning and multiple operating systems supported; high
availability features such as online repair and clustering for 24x365
computing; total conversion to 64-bit functionality for more than a decade
while some competitors are still migrating; seamless interoperability with
Microsoft® Windows NT®; and the availability of thousands of commercial and
"This release of the OpenVMS operating system, the highest quality ever,
