OpenVMS is the best designed computer operating system in the world !
It represents the "Gold Standard" in environments where stability, reliability,high performance, disaster tolerance, security, scalability and clustering are required.
Here are some facts
OpenVMS has more than 450,000 installed systems with over 10 million users
OpenVMS is the #1 rated operating system in the healthcare industry
More than 80% of the world's CPU chips are manufactured on lines running OpenVMS
More than 50% of the world's cellular phone billing systems run OpenVMS
More than 95% of the world's top stock exchanges run on OpenVMS or Tandem systems
For these reasons OpenVMS is used in many production environments and financial or medical institutions where non-interruptability and continuous computing (24 x 365) are an important issue. Military contractors also accept it as the one and only operating system for providing maximum security with maximum numerical throughput. Continuous OpenVMS system uptimes of over ten years are not unheard of.
Currently runs on the latest 64bit Integrity server product family from Hewlett-Packard with full Operating System and hardware support from a single source. HP is one of the largest and most respected technology names in the world. Eighty percent of all Global 100 companies already use Itanium based servers
Huge system performance and application scaling with 64-bit flat virtual addressing
Support for systems with 256 gigabytes of physical memory
Support for symmetric multiprocessing environments of up to 32 CPUs in a single system (and up to 96+ nodes in a cluster)
Robust file system with individual volume limits circa one terabyte (and thousands of volumes)
Built-in tools for local backup and recovery
Built-in high performance data management support (RMS)
Built-in highly sophisticated batch command processing language (DCL)
Built-in multi-user security and auditing
Built-in multiple and mixed-language programming capabilities
Support for modular coding and distributions
Built-in application debugging and application dump tools
Built-in system tuning tools
Multi-user interactive user support
Full shared-resources clustering
Supports a variety of networking protocols including COM SMB NFS IP DECnet X.25 http
Process and engineering that targets the avoidance of introducing security problems and typical virus infection paths.
A philosophy that assures upward-compatibility of user-mode applications and tools over OpenVMS releases
Powerfull and easy to use no-nonsense user interface
John P. Smith (OpenVMS Systems and Servers Group) created the OpenVMS Shark logo. He also made the following comments about the significance of choosing the Shark to represent OpenVMS
- They have both been around forever.
- They are extremely fast and flexible.
- They never stop.
- They will take on (eat) anything and continue to operate.
- They operate in packs/clusters.
And although they will never be cute they are the most efficient and effective machines in their environments.
