entorno de demostración
• 2 servidores de propósito general con Linux
• agrupación en cluster a través de enlace privado (cable cruzado)
• acceso a red de almacenamiento (SAN FC)
• cabina EMC Clariion en la red de almacenamiento
• Violin Memory en la red almacenamiento
entorno de demostración
• base de datos Oracle 11GR2 en ambos nodos
• Symantec Storage Foundation Cluster File System
• /oradata como ubiación de ficheros de datos (datafiles) y
control
• /oralog para ficheros de registro (redo log files)
• ambos sistemas de ficheros accesibles concurrentemente en los
dos nodos del cluster
