As an OPS person, it is essential to understand the hardware-related information of each server and the system-related configuration. Although not difficult, but very fragmented, information concentration is not high. So do a set of centralized display of the above information "platform" (in fact, no platform, collect-organize-show only), its principle by a "monitoring machine" (so call it) run the main scr
SQL Server and virtualization are inherently a pair, and they become more and more coordinated. The coordination between them is not only workload management and consolidation, but also high availability. New technologies can provide multiprocessor capabilities for SQL Server on multiple hosts, keeping virtual machine instances in sync with each other, so that 0 waiting for failover occurs when one instance
