El 27 de diciembre salió a la luz un nuevo libro rojo de IBM dedicado a la optimización y medida del rendimiento de Linux sobre System z ®. Su objetivo es ayudar a los administradores de sistemas responsables de la implementación de Linux para System z a comprender los factores que influyen en el rendimiento del sistema cuando se ejecuta Linux huésped de un sistema z/VM®.
Este libro comienza con la revisión de algunos de los conceptos básicos relativos a la optimización y el rendimiento, dando una visión general de algunas de las herramientas de control que están disponibles tanto para el sistema Linux como el z/VM.
Ofrece algunas recomendaciones de optimización en base a medidas obtenidas sobre un sistema IBM System z10 ® con z / VM versión 6.1 RSU 1003 en una LPAR. Como distribución Linux se utiliza SUSE Linux Enterprise Server 11 SP1. El z10 está configurado con:
- Almacenamiento principal: 6 GB
- Almacenamiento expandido: 2 GB
- Minidisc caché (MDC): 250 MB
- LPARs: 45
- Procesadores: Cuatro procesadores compartidos
Los dispositivos de almacenamiento de acceso directo (DASD) que se utiliza en la producción de esta publicación IBM Redbooks son 2105 Enterprise Storage Server ® (Shark) unidades de almacenamiento.
