BVQ version 5.3 introduces a new scanner infrastructure for SVC, Storwize and VMware systems. See: BVQ 5.3 Release notes
Comparison
New Scanner (>5.3)
The new scanner module is now consolidated into a single windows service by default ("bvq-scanner-local"). Its only purpose is to collect the information from all configured system and store them into the file system. Configurations for each system to scan are stored in the BVQ database and are managed via the BVQ Server Web UI. The BVQ Server is responsible for persisting all data into the database.
Advantages
- Much lower resource utilization
- Much easier configuration management - even without Remote Desktop Connection
- Much simpler installation process
- One scanner for all systems (SVC/Storwize & VMware)
Drawbacks
- SSH-Keys for SVC/Storwize authentication not supported any longer due to security issues
- Additional migrating step to setup the scanned systems
Old Scanners (<5.3)
BVQ was shipped with separate scanners for SVC/Storwize and VMware. For each scanned system a dedicated windows service was started with at least 512MB RAM consumption. Nearly all configuration settings had to be set during the installation process and were stored on the file system. The scanner instance was responsible for collecting all data from the system and for storing them in the database.
Advantages
- both SVC/Storwize authentication methods are supported (SSH-key authentication or password)
- Well known concept in BVQ history
Drawback
- A lot of resource overhead because of multiple windows services
- Difficult to modify configurations or delete a single scanner instance
- Limited number of instances supported
- Complex and error-prone installation process
- Coupling to database problematic in many use cases
