description
This chapter provides an overview of Enterprise Virtual Array and its components.
Introduction to the Enterprise Virtual Array
The HP StorageWorks Enterprise Virtual Array family is a high performance, scaled capacity, on demand,
"virtual" RAID storage system.
This storage system is designed for environments where improved storage use and scalability is critical. It
meets application-specific demands for consistently high transaction I/O (input/output) and MB data
rate performance, and provides seamless capacity expansion, instantaneous replication, and simplified
storage administration.
The Enterprise Virtual Array (EVA) is available in multiple configurations—each optimized for
general-purpose commercial environments and high-performance technical computing environments. The
solutions include support for multivendor operating system platforms and stringent data center availability
enhancements, such as multipathing and clustering.
This guide includes information for two Enterprise Virtual Array products: EVA5000 and EVA3000.
• EVA5000—available in multiple configurations ranging from the single-rack 2C2D configuration
to the multi-rack 2C18D. The EVA5000 includes two HSV110 controllers and four FC loop switches.
• EVA3000—available in configurations ranging from the 2C2D configuration to the 2C4D
configuration. The EVA3000 includes two HSV100 controllers and no loop switches. Multiple
EVA3000s can be installed in a single rack.

Features and enhancements
The Enterprise Virtual Array provides many features and enhancements which are detailed in the sections
that follow.
Ease of management
Easy-to-use storage management tools:
• Software tools that allow you to manage larger SAN configurations with more servers and more
storage solutions
• HP-supplied disk drives conform to the enclosure-initiated Enclosure Services Interface (ESI)
• State-of-the-art controller software
• Completely integrated configurations with a single part number, plus disk drives and storage
system software
Data availability
• Redundant hardware design and value—added software eliminate single points of failure from
server to storage in clustered or single server configurations with multipathing.
• Full support for local and remote data replication using optional HP StorageWorks Business Copy
EVA and HP StorageWorks Continuous Access EVA applications.
