1 Enterprise Virtual Array description
The HP 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 six Enterprise Virtual Array products: EVA8000/8100, EVA6000/6100, and EVA4000/4100.
• EVA8000/8100 — available in multiple configurations ranging from the single-rack 2C2D
configuration to the multi-rack 2C18D. The EVA8000 includes two HSV210-A controllers and
four Fibre Channel loop switches. The EVA8100 includes two HSV210-B controllers and four
Fibre Channel loop switches.
• EVA6000/6100 — available in configurations ranging from the 2C4D configuration to the
2C8D configuration. The EVA6000 includes two HSV200-A controllers and two Fibre Channel
loop switches. The EVA6100 includes two HSV200-B controllers with two Fibre Channel loop
switches.
• EVA4000/4100 — available in configurations ranging from the 2C1D configuration to the
2C4D configuration without loop switches. The EVA4000 includes two HSV200-A controllers.
The EVA4100 includes two HSV200-B controllers. Multiple EVA4000/4100s can be installed
in a single rack.
See the HP 4x00/6x00/8x00 Enterprise Virtual Array Hardware Configuration Guide for more information about configurations. See “Related information” (page 107) for links to this document.

Direct connect
NOTE: Direct connect is currently supported on Microsoft Windows only. For more information
on direct connect, go the Single Point of Connectivity Knowledge (SPOCK) at: http://www.hp.com/
storage spock.
Direct connect provides a lower cost solution for smaller configurations. When using direct connect, the storage system controllers are connected directly to the host(s), not to SAN Fibre Channel switches. Make sure the following requirements are met when configuring your environment for direct connect:
• A management server running HP Command View EVA must be connected to one port on
each EVA controller. The management host must use dual HBAs for redundancy.
• To provide redundancy, it is recommended that dual HBAs be used for each additional host
connected to the storage system. Using this configuration, up to four hosts (including the
management host) can be connected to an EVA8x00, and up to two hosts can be connected
to an EVA6x00 or EVA4x00.
• The Host Port Configuration must be set to Direct Connect using the OCP.
• HP Continuous Access EVA cannot be used with direct connect configurations.
• The HSV controller firmware cannot differentiate between an empty host port and a failed
host port in a direct connect configuration. As a result, the Connection state dialog box on
the Controller Properties window displays Connection failed for an empty host port. To fix this
problem, insert an optical loop-back connector into the empty host port; the Connection state
will display Connected. For more information about optical loop-back connectors, contact
your HP-authorized service provider.
20 Enterprise Virtual Array startup
iSCSI connection configurations

connected to one storage system controller.
• In a dual MPX100 configuration, at least one FC port from each MPX100 must be connected
to one storage system controller.
• The Host Port Configuration must be set to Fabric Connect using the OCP.
• HP Continuous Access EVA is supported on the same storage system connected in MPX100
fabric connect configurations.
Direct connect iSCSI
Direct connect provides a lower cost solution for configurations that want to dedicate controller ports to iSCSI I/O. When using direct connect, the storage system controllers are connected directly to the MPX100(s), not to SAN Fibre Channel switches.
Make sure the following requirements are met when configuring your MPX100 environment for direct connect:
• A maximum two MPX100s per storage system are supported.
• In a single MPX100 configuration, if both MPX100 FC ports are used each port must be
connected to one storage system controller.
• In a dual MPX100 configuration, at least one FC port from each MPX100 must be connected
to one storage system controller.
• The Host Port Configuration must be set to Direct Connect using the OCP.
• HP Continuous Access EVA cannot be used with direct connect configurations.
• EVAs cannot be directly connected to each other to create HP Continuous Access EVA
configuration. However, hosts can be direct connected to the EVA in a HP Continuous Access configuration. At least one port from each array in an HP Continuous Access EVA configuration must be connected to a Fabric connection for remote array connectivity.

Entering the WWN
Fibre Channel protocol requires that each controller pair have a unique WWN. This 16-character alphanumeric name identifies the controller pair on the storage system. Two WWN labels attached to the rack identify the storage system WWN and checksum. See Figure 5 (page 23).
NOTE:
• The WWN is unique to a controller pair and cannot be used for any other controller pair or
device anywhere on the network.
• This is the only WWN applicable to any controller installed in a specific physical location,
even a replacement controller.
• Once a WWN is assigned to a controller, you cannot change the WWN while the controller
is part of the same storage system.
Figure 5 Location of the World Wide Name labels

3 Enterprise Virtual Array hardware components
This chapter describes the Enterprise Virtual Array hardware components.
Fibre Channel drive enclosures
The drive enclosure contains the disk drives used for data storage. A storage system includes multiple drive enclosures. The major components of the enclosure are:
• 3U enclosure
• Dual redundant, active-to-active 2 Gbps FC loops
• 2.125-Gb, dual loop, 14-drive enclosure
• Dual 2 Gbps FC I/O modules (A and B loops)
• Copper Fibre Channel cables
• Fibre Channel disk drives and drive blanks
• Dual redundant power supplies
• Dual redundant blowers
• Cache batteries
• Environmental Monitoring Unit (EMU)
Enclosure layout
The disk drives mount in bays in the front of the enclosure. The bays are numbered sequentially from left to right. A drive is referred to by its bay number. Enclosure status indicators are located in the lower-right, front corner. Figure 6 (page 26) shows the front and rear views of the FC drive enclosure.

26 Enterprise Virtual Array hardware components
I/O modules
Two I/O modules provide the interface between the drive enclosure and the host controllers. See
Figure 7 (page 27). They route data to and from the disk drives using Loop A and Loop B, the
dual-loop configuration. For redundancy, only dual-controller, dual-loop operation is supported. Each controller is connected to both I/O modules in the drive enclosure.
Figure 7 I/O module
1. Status indicators (Upper port, Power, and Lower port)
2. Upper port
3. Lower port
The I/O modules are functionally identical, but are not interchangeable. Module A can only be installed at the right end of the enclosure, and module B can only be installed at the left end of the enclosure. See Figure 6 (page 26).
Each I/O module has two ports that can both transmit and receive data for bidirectional operation. Activating a port requires connecting a FC cable to the port. The port function depends upon the loop. See Figure 8 (page 27).
Figure 8 Input and output ports
2. Loop A upper port1. Loop A lower port
4. Loop B upper port3. Loop B lower port
I/O module status indicators
There are three status indicators on the I/O module. See Figure 7 (page 27). The status indicator states for an operational I/O module are shown in Table 2 (page 28). Table 3 (page 28) shows the status indicator states for a non-operational I/O module.

Fiber Optic Fibre Channel cables
The Enterprise Virtual Array uses orange, 50-µm, multi-mode, fiber optic cables for connection to the SAN. The fiber optic cable assembly consists of two 2-m fiber optic strands and small form-factor connectors on each end. See Figure 9 (page 29).
28 Enterprise Virtual Array hardware components
To ensure optimum operation, the fiber optic cable components require protection from contamination and mechanical hazards. Failure to provide this protection can cause degraded operation. Observe the following precautions when using fiber optic cables.
• To avoid breaking the fiber within the cable:
Do not kink the cable◦
◦ Do not use a cable bend-radius of less than 30 mm (1.18 in)
• To avoid deforming, or possibly breaking the fiber within the cable, do not place heavy objects
on the cable.
• To avoid contaminating the optical connectors:
Do not touch the connectors◦ ◦ Never leave the connectors exposed to the air ◦ Install a dust cover on each transceiver and fiber cable connector when they are
disconnected
If an open connector is exposed to dust, or if there is any doubt about the cleanliness of the connector, clean the connector as described in “Handling fiber optic cables” (page 76).
Figure 9 Fiber Optic Fibre Channel cable
Copper Fibre Channel cables
The Enterprise Virtual Array uses copper Fibre Channel cables to connect the drive enclosures to each other, or to the loop switches and to the HSV controllers. The cables are available in 0.6-meter and 2.0-meter lengths. Copper cables provide performance comparable to fiber optic cables. Copper cable connectors differ from fiber optic small form-factor connectors (see Figure 10 (page
29)).
Figure 10 Copper Fibre Channel cable
Fibre Channel disk drives
The Fibre Channel disk drives are hot-pluggable and include the following features:
• Dual-ported 2-Gbps Fibre Channel drive enclosure interface that allows up to 120 disk drives
to be supported per Fibre Channel drive enclosure pair
• Compact, direct-connect design for maximum storage density and increased reliability and
signal integrity
• Both online high-performance disk drives and FATA disk drives in a variety of capacities and
spindle speeds
• Better vibration damping for improved performance
Up to 14 disk drives can be installed in a drive enclosure.
Fibre Channel drive enclosures 29
