SCST solución de Almacenamiento Abierto en FCP

Dedicamos una serie de artículos a conocer el proyecto  SCST como virtualizador de almacenamiento en Open Source.

Su implementación para targets de almacenamiento iSCSI está bastante difundido pero no lo es tanto en fibra óptica (FCP). Tanto Qlogic como Emulex, líderes en el mercado del chipset de comunicaciones en HBAs, han liberando su versión de drivers que conmutan de initiator a target, haciendo posible conocer el funcionamiento, protocolos de comunicación y adecuación a estándares  provocados por proyectos abiertos como SCST en Linux o COMSTAR en OpenSolaris.

Como pasó en su momento con el proyecto Xen en el campo de la virtualización, no queda mucho para ver como las distribuciones enterprise UNIX cercanas al Open Source contendrán en sus repositorios el driver dual (initiator/target) de las HBAs. De esta forma un servidor podrá convertirse en una cabina de almacenamiento, o podrá emular cualquier otro dispositivo de fibra. Esta tendencia en la actualidad es liderada por Oracle/Sun Microsystems en sus productos OpenStorage (incluye modo target de Fibra basado en COMSTAR) u OpenSolaris/Solaris Express 11 (llevan los drivers duales para emulex y qlogic). Distribuciones UNIX enterprise como Redhat , Novell/Suse y Ubuntu contendrán en su Sistema Operativo en breve soluciones equivalentes basadas en SCST, pudiendo provocar un golpe de efecto en el negocio del almacenamiento en fibra.

Hemos elaborado varios artículos sobre el software SCST con el objetivo de difundir el proyecto y mostrar diferentes implementaciones en nuestro laboratorio :

– ¿Qué es SCST?


– Disco de fibra emulado con SCST


– Pruebas de Disco sobre FC basado en SCST
