The document discusses MySQL server architecture and high availability solutions. It provides an overview of MySQL's architecture including storage engines, clients, connectors and pluggable components. It then summarizes high availability options like replication, shared disk clusters, DRBD and MySQL Cluster, highlighting features like redundancy, fault tolerance and performance. The document concludes with an introduction to MySQL Enterprise Monitor for management and a brief overview of performance improvements in MySQL 5.5.

Shared Disk Clusters Active/Passive server or process configuration Links servers with 3rd party software and virtual IP Reliability Commonly used solution Fault Tolerance No single point of failure with appropriate hardware High Availability Data handled by a SAN or NAS and always available Automatic fail-over Simplified Management Cluster management utilities Sun Cluster Red Hat Enterprise Server Novell Suse Enterprise Server Veritas Cluster Server Linux HA with Heartbeat HP Serviceguard SCO Reliant-HA Microsoft Cluster Server MySQL Server Nodes Shared Storage Applications

10. DRBD Distributed Replicated Block Device Runs over standard IP networks Distributed storage Similar to network RAID Synchronous Characteristics No special networking components (except Heartbeat) Excellent performance (blocks vs. rows of data) Manages inconsistencies of data during a failure Hides the complexity of many recovery actions Linux heartbeat manages fail over and virtual IPs Applications Virtual IP Active Node Passive Node DRBD
