La recuperación de desastres impulsa la estrategia de virtualización, pero mucho personal TI no conoce los costes ocultos

LONDRES, June 9, 2011 /PRNewswire/ --

Una encuesta realizada el año pasado por Techtarget mostró que el 33% por ciento planeó utilizar una estrategia de virtualización para aprovechar la recuperación de desastres y los beneficios de la alta disponibilidad.

El 23% también vio los beneficios de la virtualización como una solución de backup y de protección de datos. Una encuesta independiente realizada este año por Coleman Parkes y encargada por CA Technologies mostró que el tiempo de inactividad cuesta a las empresas más de 127 millones de horas por persona al año.

"Asegurar el tiempo de actividad es una prioridad en la lista para los administradores TI. Con la virtualización puede mover automáticamente máquinas virtuales de un host a otro e incluso de un centro de datos a otro, de modo que pueden estar operativos y ejecutándose, con poco o sin tiempo de inactividad, en caso de fallo," dijo Mandeep Birdi, consultor preventas sénior en Diskeeper Corporation Europe.

Sin embargo, más del 30% de los usuarios de virtualización VMware y Microsoft identificaron la copia de seguridad de los datos VM como un reto, y también identificaron la gestión del almacenamiento, embotellamientos I/O y control de disponibilidad del servidor como grandes retos de la virtualización.

Otra encuesta realizada por Diskeeper Corporation Europe de 500 empleados TI mostró que el 80% conocían los principales problemas de los embotellamientos I/O.

Mandeep Birdi comentó: "Los recursos compartidos efectivamente son de esencial importancia en un entorno virtual, pero se ven gravemente afectados por tres barreras clave: embotellamientos de ancho de banda I/O debido a la fragmentación acelerada en las plataformas virtuales, máquinas virtuales que compiten por recursos I/O compartidos y no priorizados efectivamente en la plataforma y, en tercer lugar, discos virtuales configurados para crecer dinámicamente no se reescalan cuando se eliminan datos, un problema conocido como bloating. En su lugar, el espacio libre simplemente se desecha. Estos problemas pueden provocar costes para la empresas innecesarios en hardware adicional así como la pérdida de tiempo en tratar estos problemas."

La encuesta también destacó que el 25% de los encuestados no tratan los problemas de los embotellamientos I/O, mientras que el 5% dijo que sólo compran más discos/ ejes.

Además de esto, Mandeep Birdi también registró que a muchos usuarios TI que están migrando o han migrado en un entorno virtual, y han empleado tradicionalmente una SAN, se les dice que no necesitan desfragmentar la SAN, y no hay un problema de embotellamiento de I/O. Comentó: "Esto es falso. El problema de embotellamiento I/O puede tener un enorme efecto en el rendimiento y si un cliente no sabe que esto ocurre en el entorno SAN, puede terminar costando mucho dinero a la empresa al pensar que tienen que adquirir más hardware, cuando no es el caso en absoluto."
