San Diego '99
Building a Basic OpenVMS SCSI Cluster for High Availability
- Topic Area:
- Track: Open VMS
- Topic: Clusters
- Type: Breakout Session
03:00 PM Duration:
- Wes Roberts
- Systems Administration Manager, Bell & Howell - Information and Learning
- This session is based on the recent efforts of UMI staff to acquire and install a three node SCSI (Small Computer System Interface)OpenVMS/Alpha Cluster for a high availability application. Topics
- System requirements.
- Cluster components, their options and alternatives.
- Configuring for high availability, an exercise in paranoia.
- Limitations discovered; the pros and cons of SCSI based clusters.
- The detailed configuration, including why the items chosen were chosen.
- Description of hardware and software installation steps,including the tips and tricks we learned along the way.
The three node SCSI cluster at Bell & Howell - Information and Learning was purchased as a replacement for a three node VAX 4000 based DSSI cluster. The project was justified on maintenance cost savings. The new systems are paying for themselves within two years, so affordability was a major configuration requirement. The new cluster is now in production.
- Understand the hardware components of a basic OpenVMS SCSI Cluster and how they go together.
- Understand the advantages and disadvantages of using a SCSI based cluster for a high availability environment.
- Understand the OpenVMS installation steps necessary to implement a SCSI cluster.
- Prerequisites for attendees:
- A general understanding of OpenVMS Cluster configurations, topology and functionality is suggested.
- Required Skill Level:
Assumes general knowledge of topic, familiarity w/basic terms & procedures
