Customers regularly engage SIOS for consultancy services such as high availability (HA) health check services and training. This helps customers keep their IT infrastructure in good working order and keeps their staff trained to operate it.
High Availability Health-Check Services
Health check services are a Professional Services offering from SIOS that checks the customer’s SIOS server infrastructure and produces a report for the customer. A detailed review of the SIOS HA LifeKeeper environment is performed, as well as a thorough examination of the product logs and customer run logs. During this review, version levels, communication paths, quorum, Application Recovery Kits, and tuning parameters are examined and compared against recommended settings. A report is generated with any potential risks outlined and actionable suggestions for improvements.
High Availability Optimization
Optimization of High Availability services can be broken down into two areas:
- High availability optimization – this optimization reduces downtime and maintains the operational uptime of a system. This is achieved by the use of system-initiated failovers and user-initiated switchovers to a backup hardware system that can take over when a primary system fails or is manually switched over. A Disaster Recovery (DR) node may be positioned on a WAN so that if the main LAN-based nodes go down, fast recovery can be achieved by failing over to the DR node. Backups may also be routinely made, so that recovery of specific files can be performed if needed.
- Cost-optimized high availability – this optimization examines a customer’s system to determine the best way to offer redundancy, while keeping costs down. This may involve using cloud services for scaling and utilizing lower-tiered services to reduce cost. Serverless architectures with a pay-per-use model can also be used. All of this reduces hardware costs.
High Availability Training
SIOS offers on-demand high availability product training for LifeKeeper for Linux and DataKeeper for Windows products through the Udemy training platform.
Additionally, SIOS offers remote custom training for organizations via the Professional Services organization for these products, which come with training materials and self-guided exercises. For the DataKeeper course, an Individualized breakout/consultancy session is available.
