Terms in this definition
- vSAN

- Performance
Routing method in Traffic Manager that directs users to whichever endpoint offers the lowest latency.
- IOPS
Input/output operations per second measure how fast a disk performs; a P50 disk, for instance, offers 7,500.
- VCF Operations
VCF's console for running the fleet. It covers alerting, monitoring, capacity, reporting, log analysis and licensing alongside fleet management of identity, passwords, certificates and lifecycle.
