Guru Enterprise Server provides a pair of redundant 1U rack mounted servers for use with 10 or more Cassini ATE systems. Guru provides disaster recovery for Cassini ATE and seamless development environment for Cassini Virtual Workstations. See Guru Description for the complete feature list.
The following options determine how much IT involvement is necessary to maintain operations and availability with cost determining the reliability and recoverability of Guru Enterprise Server by adding redundancy. Additional Hardware options are available for running Guru Server on a test floor, outside of IT department management.
- Guru Server Rack
- Unmanaged Gigabit Network Switches
- Dual Power Conditioners
- Dual UPS
- Local Terminal (4/8 port KVM with Keyboard/Mouse/Monitor)
Automatic Load Balancing vs Network Structure: affects performance and reliability
Datalog Guru Connection Load Balancing
- Improves performance by isolating Datalog transfers to a separate pair of Guru Servers. Isolation of issues provides greater reliability. For example, if the NFS server for a mounted drive does not respond, it could affect upstream performance of Guru queries. By using one pair for Update/Backup and another pair for Datalog transfers, the tester will not be affected by upstream STDF agent issues.
Facility Disaster Recovery: affects restoration of service after catastrophic hardware failure, off site backup scenarios
- Configure connection for low latency, small bandwidth "backup" tasks.
- Server Based Local Subnet (Automatic load balance and failover with zeroconfig)
- Client Based Address Book (manually configured priorities used to load balance)
- Server Based Network Wide (Zeroconfig Proxy required, not supported by RI)
