Executive summary

The HP Enterprise Virtual Array (EVA) family has been designed for mid-range and enterprise

customers with critical requirements to improve storage utilization and scalability. EVA arrays can

fulfill application-specific demands for transactional I/O performance, while supporting easy capacity

expansion, instantaneous replication, and simplified storage administration.

The combination of an EVA array, HP Command View EVA software and VMware vSphere 4 and 5

provides a comprehensive solution that can simplify management and maximize the performance of a

vSphere infrastructure.

HP continues to develop and improve best practices for deploying P6000/EVA arrays with vSphere 4

and 5. This white paper describes a broad range of best practices for a Fibre Channel (FC)

implementation; iSCSI and Fibre Channel over Ethernet (FCoE) implementation are outside the scope

of this paper.

Target audience: vSphere and SAN administrators that are familiar with the vSphere infrastructure

and virtual storage features, the EVA array family, and Command View EVA.

The challenges

With vSphere 4.x, VMware continues to stretch the boundaries of scalability through features that

include:

 Support for 255 GB of RAM per virtual machine (VM)

 Support for 8 virtual CPU per VM

 Support for 160 cores for host server

 High-performance SCSI virtual adapter

 Support for up to 320 VMs on a single server

 Modular storage stack that is closely integrated with the particular storage array

For administrators, this feature-packed hypervisor raises several questions about effectively

configuring, tuning and deploying vSphere 4.x and 5.0 in their respective SANs.

 Setting up the optimal storage configuration

 Selecting the appropriate I/O path policy

 Simplifying storage management, even in a complex environment with multiple storage systems

 Effectively monitoring the SAN so that you can make adjustments when needed
