OpenVMS: 

OpenVMS When your system absolutely has to run

What is OpenVMS?: 

What is OpenVMS? The dominant force in the minicomputer revolution Rated as the #1 OS in the healthcare industry (1996) The first OS to run 24x365 (1985) and still the leader The first OS to scale from desktop to data center (1987) The first disaster tolerant OS (1988) and still the leader The first OS to ship CORBA, one of the first to ship DCE, and the first non-UNIX OS to ship POSIX and SPEC 11/70 The first OS to run 3-tier client/server and still the leader The second OS to run 64-bits The most highly scalable OS in the world today

You’re going to have to answer some questions:: 

You’re going to have to answer some questions: Is OpenVMS a good long-term strategic investment? Is OpenVMS also strategic to Oracle?

OpenVMS Business Summary: 

OpenVMS Business Summary FY98 - $70M budget 500 person Engineering organization Oracle 12 engineers onsite $1.5M funding #1 Operating System in Healthcare* 23% growth 15% new business * based on 1997 CHIME study

OpenVMS Engineering plan for the next five years: 

OpenVMS Engineering plan for the next five years Deliver innovative, leading edge Affinity systems in partnership with customers into the 21st century Be the ultimate high-end for Windows NT Be a superb Database and Internet server Raise the bar for availability Raise the bar for scalability

OpenVMS and Windows NT Strategy: 

OpenVMS and Windows NT Strategy OpenVMS as Continuous Computing Server Enterprise strength Bulletproof 24x365 Highly scalable Proven in the most demanding environments 64 bits/VLM Highly Available Internet Servers Memory Channel Clusters Galaxy OpenVMS & Windows NT Connectivity Applications Development environment Momentum PC volume economics 3 Tier C/S ADE Seamless Access to Data Affinity System Management Windows Gateway to OVMS Distributed TP “The seamless integration of OpenVMS with Windows NT will enable OpenVMS customers to combine the proven enterprise strengths of OpenVMS with the new foundation of Windows NT applications.” - Bill Gates Microsoft/Digital, August 2, 1995

…and a few more questions: 

…and a few more questions Does OpenVMS have the mission critical functionality we need? Does OpenVMS scale? Where is OpenVMS going in the future?

What is “excellence” in availability in 1997?: 

What is “excellence” in availability in 1997? Paris: May 5, 1996

OpenVMS clusters offer a long list of unmatched availability features : 

OpenVMS clusters offer a long list of unmatched availability features Up to 96 nodes and 28 petabytes in a cluster Distributed lock manager Cluster file system Multi-site deployment Wide-area shadowing Automatic failover Automated volume shadowing On-line back-up Rolling upgrades for: Hardware Systems software Application software

OpenVMS certainly scales well enough as a stand-alone system: 

OpenVMS certainly scales well enough as a stand-alone system Rdb Gains Index scan - 55X Indexed Data Retrieval - 146X 3-way Join - 142X 5-way Join - 216X Single system record holder - 14,227 tpm-C - April 1997 64 Bits for VLM, VLDB

And OpenVMS scales REALLY well in clusters…and can be multi-site disaster-tolerant besides:

Leadership functionality: Disaster-tolerant computing System Disk Data Disk Data Disk Shared Disks GIGAswitch System Disk Data Disk Data Disk Shared Disks GIGAswitch T3 or FDDI or ATM Shadowed Disks Site “A” Site “B” Easy to manage - Single system view Operation Management Software provides management of configuration from either site Automatic transfer in seconds in event of disaster Integrated, tested, installed system solution - 5 yrs of experience

OpenVMS Galaxy Technology: 

OpenVMS Galaxy Technology Brings multi-system performance, availability & scalability to a single system An extension/evolution of current OpenVMS arch S/W arch that adapts to the way you do computing partitions a single machine into multiple SMP nodes environment is adaptive and dynamic multiple instances of OS execute in a single computer Addresses limitations in current system archs: clusters: lack of shared memory and interconnect SMP: S/W scalability and single system view MPP: limited applications, management Digital Proprietary and Confidential

OpenVMS Galaxy Technology (cont): 

OpenVMS Galaxy Technology (cont) Consists of two components: APMP (Adaptive Partitioned Multi-Processing) model Galaxy Softwared Architecture to exploit APMP 4 Modes of Operation: Shared Nothing: partition CPU’s for dedicated apps Shared Partial: shared memory for VLDB Shared Everything: shared mem & cluster interconnect Adaptive Dynamic Resource Partitioning: migration resiliency Capabilities: 1-256 CPUs 300,000+ to 1,000,000 design goal dynamice resource allocations hot swap of CPU, mem, I/O Digital Proprietary and Confidential

Galaxy Implications: 

Galaxy Implications Shared memory Very large database cache Node reboot into “hot” cache DLM cache now local vs distributed Shared memory cluster interconnect SMP Improved SMP scaling Improved SMP affinity CPU Migration Partitioning of CPUs I/O Multiple primaries for INT Distribute INT to secondaries Can partition I/O workload Highly scalable I/O subsystem Reliability / Availability Hotswap (CPU, Memory, I/O) OS will fail out only the necessary subsystem Software failure will not compromise entire system OS Resilliency (dynamic reallocation or resources) Digital Proprietary and Confidential
