Hitachi Adaptable Modular Storage 2000 Family

This document provides specific recommendations to ensure effective deployments of VMware virtual infrastructure environments, particularly in server farm environments.

New Hitachi storage system availability and performance features along with VMware fixed multipathing policies allow organizations to maximize the effectiveness of applications deployed on Hitachi Adaptable Modular Storage 2000 family systems with VMware virtual infrastructure environments. This document describes configuration alternatives and explains the benefits of using fixed rather than most recently used (MRU) multipathing policy. The document does not address use of the experimental round robin load-balancing feature of VMware virtual infrastructure environments.

With the introduction of automatic load balancing to the 2000 family, LUNs are optimally balanced between dual controllers to spread the I/O workload across resources. In addition, the active-active design of the 2000 family makes all LUNs accessible regardless of the physical port or the server from which the access is requested. This document provides specific recommendations to ensure effective deployments of VMware virtual infrastructure environments, particularly in server farm environments.
