This chapter describes the procedures to install and configure the Enterprise Virtual Array. When
these procedures are complete, you can begin using your storage system.
NOTE:Installation of the Enterprise Virtual Array should be done only by an HP authorized
service representative. The information in this chapter provides an overview of the steps involved
in the installation and configuration of the storage system.
This chapter consists of:
EVA8000/8100 storage system connections
Figure 1 (page 11) shows how the storage system is connected to other components of the storage
solution.
•The HSV210-A and HSV210-B controllers connect via four host ports (FP1, FP2, FP3, and FP4)
to the Fibre Channel fabrics. The hosts that will access the storage system are connected to
the same fabrics.
•The HP P6000 Command View management server also connects to the fabric.
•The controllers connect through two loop pairs to the drive enclosures. Each loop pair consists
of two independent loops, each capable of managing all the disks should one loop fail. Four
FC loop switches are used to connect the controllers to the disk enclosures.

Figure 3 (page 13) shows a typical EVA 4000/4100 SAN topology:
•The HSV200-A and HSV200-B controllers connect via two host ports (FP1 and FP2) to the
Fibre Channel fabrics. The hosts that will access the storage system are connected to the same
fabrics.
•The HP P6000 Command View management server also connects to both fabrics.
•The controllers connect through one loop pair to the drive enclosures. The loop pair consists
of two independent loops, each capable of managing all the disks should one loop fail. The
controllers connect directly to the disk enclosures.
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 P6000 Command View 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 P6000 Continuous Access 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.
Direct connect13
iSCSI connection configurations
The EVA4x00/6x00/8x00 support iSCSI attach configurations using the HP MPX100. Both fabric
connect and direct connect are supported for iSCSI configurations. For complete information on
iSCSI configurations, go to the following website:
NOTE:An iSCSI connection configuration supports mixed direct connect and fabric connect.
Fabric connect iSCSI
Fabric connect provides an iSCSI solution for EVA Fibre Channel configurations that want to
continue to use all EVA ports on FC or if the EVA is also used for HP P6000 Continuous Access.
Make sure the following requirements are met when configuring your MPX100 environment for
fabric connect:
•A maximum of two MPX100s per storage system are supported
•Each storage system port can connect to a maximum of two MPX100 FC ports.
•Each MPX100 FC port can connect to a maximum of one storage system port.
•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 Fabric Connect using the OCP.
•HP P6000 Continuous Access 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 P6000 Continuous Access cannot be used with direct connect configurations.
•EVAs cannot be directly connected to each other to create an HP P6000 Continuous Access
configuration. However, hosts can be directly connected to the EVA in an HP P6000 Continuous
Access configuration. At least one port from each array in an HP P6000 Continuous Access
configuration must be connected to a Fabric connection for remote array connectivity.

See the HP 4x00/6x00/8x00 Enterprise Virtual Array Hardware Configuration Guide for more
information about configurations. See “Related information” (page 101) for links to this document.
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-Gbps, 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
•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 20) shows the front and rear views of the FC drive
enclosure.

I/O modules
Two I/O modules provide the interface between the drive enclosure and the host controllers. See
Figure 7 (page 21). 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.

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 20).
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 21).

22Enterprise Virtual Array hardware components
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 23).
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 71).
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
23)).
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
Fibre Channel drive enclosures23
Up to 14 disk drives can be installed in a drive enclosure.
Disk drive status indicators
Three status indicators display the drive operational status. Figure 11 (page 24) shows the disk
drive status indicators. Table 4 (page 24) provides a description of each status indicator.

The disk drive status indicators can assume three states: on, off, or flashing. The status indicators
states for operational drive status are shown in Table 5 (page 24). See Table 6 (page 25) for the
non-operational drive status indicator states.
Table 5 Operational disk drive status indications
This green status indicator flashes when the disk drive is being
accessed. It is on when the drive is idle.
The green status indicator is on when the disk drive is online
and operating normally. This indicator will be off in the
following situations:
• There is no controller on the bus.
• +5.1 VDC is not available.
• The drive is not properly installed in the enclosure.
This amber status indicator is on when there is a disk drive
failure. Depending on the host controller, this indicator may
flash when the controller detects an error condition.
The amber status indicator flashes in synchronization with
the other two status indicators in response to the EMU locate
command.

Power supplies
The two power supplies mount in the rear of the enclosure. See Figure 23 (page 50). The supplies
are autoranging and operate on a country-specific AC input voltage of 202 to 240 VAC ±10%,
50 to 60 Hz, ±5%, (188 to 264 VAC, 47 to 63 Hz).
The DC outputs of this power supply are:
•+5.1 VDC for the EMU, I/O module, backplane, and disk drives
•+12.1 VDC for the disk drives
•+12.5 VDC for the disk drives
Fibre Channel drive enclosures25
Blowers
The output of each power supply is 499 W, with a peak output of 681 W. A single power supply
can support an enclosure with a full complement of disks.
The power supply circuitry provides protection against:
•Overloads
•Short circuits
•Overheating
Power supply status and diagnostic information is reported to the EMU with voltage, current, and
temperature signals.
See “Regulatory notices and specifications” (page 104) for the enclosure power specifications.
The power supply temperature sensor provides a temperature range signal to the EMU, which uses
this signal to set the blower speed.
The power supply internal temperature can also control the speed of the blower. The higher the
power supply temperature, the faster the speed of the blower. If the power supply temperature
exceeds a preset value, the power supply automatically shuts down.
The power supply-mounted blowers cool the enclosure by circulating air through the enclosure.
The blowers, under the control of the EMU or the associated power supply, can operate at multiple
speeds. This ensures that, when the enclosure temperature changes, the blowers can automatically
adjust the air flow.
If a blower is operating too slowly or has stopped (a “blower failure”), internal circuitry automatically
operates the remaining blower at a higher speed. Simultaneously, the error condition is reported
in several ways, including the power supply indicator, the audible alarm, the enclosure fault
indicators, and the EMU alphanumeric display.
Should both blowers fail, the power supplies automatically shut down.
NOTE:The blowers are field-replaceable units and can be replaced, individually, while the
system is running. The blowers are also interchangeable. The failure of a power supply +12.5
VDC circuit disables the associated blower.
The status indicator on the blower displays the status of both the power supply and the blower.
See Figure 12 (page 25). See Table 7 (page 26) for definitions of the indicator displays.

The EMU provides increased protection against catastrophic failures. The EMU detects conditions
such as failed power supplies, failed blowers, elevated temperatures, and external air sense faults
and communicates these conditions to the storage system controllers.

EMU functions
The primary functions of the EMU include:
•Using the Enclosure Services Processor (ESP) to control the Enclosure Services Interface (ESI)
•Assigning the Enclosure Number (En), based upon the cabinet address bus feature.
•Displaying the bay 1 loop ID.
•Monitoring enclosure operation.
and communicate with the controllers.
•Detecting, reporting, recording, and displaying conditions.
•Displaying EMU, enclosure, and element status.
•Implementing automatic corrective actions for some conditions.
Fibre Channel drive enclosures27
•Providing enclosure status data to the controllers.
•Reporting the WWN and the logical address of all disk drives.
NOTE:Although the EMU can determine the logical address of a drive, the EMU can neither
display nor change this information. HP P6000 Command View can display the addresses from
the EMU-supplied status information.

EMU displays
The EMU uses a combination of status indicators, alphanumeric display, and an audible alarm to
indicate the operational status of the enclosure and its components. See Table 9 (page 28).

Using the alphanumeric display
The two-character alphanumeric display is located at the top of the EMU (see Figure 13 (page
27)). This seven-segment display provides information about multiple enclosure functions. The
push-button control the data displayed or entered.
Alphanumeric display description
The top-level, two-character alphanumeric display (En, Li, rG, Au, and Er), is the display group.
The function of the other displays is display-group dependent. The default display is the enclosure
number, a decimal number in the range 00 through 14. The push-button allow you to select the
alphanumeric display or to enter data.
•The bottom push-button sequentially moves between groups and selects a display group.
See Table 11 (page 30) for a description of these display groups.
•he top push-button moves between the levels within a display group (see 2, Figure 13 (page
27)).
Display groups
When you press and release the bottom push-button, the alphanumeric display selects a different
display group. Table 11 (page 30) describes the display groups.

EMU pushbutton status indicators
The enclosure number is the default display and is a decimal number
in the range 00 through 14. See “Enclosure number feature” (page
32) for detailed information.
This display group has a single sublevel display that defines the
enclosure bay 1 loop ID. Valid loop IDs are in the range 00 through
7F.
This display group has two two-digit displays that define the reporting
group number in the range 0000 through 4095.
This display group provides control over the audible alarm or horn.
The sublevel displays are audible alarm enabled (on) or audible alarm
disabled (oF). See “Audible alarm operations ” (page 30) for detailed
information.
This display group defines the EMU code firmware version.Firmware RevisionFr
This display group reads Er when there is an error condition.Error ConditionEr
The pushbutton status indicators display error conditions and the state of the audible alarm.
•When an error condition exists, the top pushbutton status indicator is On.
For a single error condition, the status indicator is On until the error condition is viewed.◦
◦For multiple errors, the status indicator is On until the last error condition is viewed.
•The bottom pushbutton indicator is On only when the alarm is muted or disabled.
Audible alarm operations
Whenever an error condition exists, the audible alarm automatically sounds until all errors are
corrected. You have the option of either muting or disabling the alarm.
•Disabling the audible alarm prevents it from sounding for any error condition.
•Muting the alarm silences it for the existing condition, but any new condition causes the alarm
to sound.
Audible alarm patterns
The audible alarm sound pattern differs depending on the type of error condition. See
Table 12 (page 30) for the duration and the approximate relationship of these alarms. The most
severe, active error condition controls the alarm pattern.
