Preparing
Preparing the site
Prerequisites
• Place your system in an approved environment to ensure continuous, safe, and reliable operation of your equipment.
• Consider using the Hewlett Packard Enterprise Configurator (eCO) to help plan and configure racks and rack-
mountable devices. The eCO is available on the Hewlett Packard Enterprise One Config Simple (OCS) website.
Procedure
1. Provide adequate structural support.
Calculate the total weight of your equipment and verify that your site can support the weight. For HPE ProLiant server
environments, consider using Rack Builder, a software tool that provides a simplified method to planning and
configuring racks and rack-mountable products. Rack Builder is available on the Options tab of the ProLiant Home
page of the Hewlett Packard Enterprise Servers and Systems website.
2. Provide adequate clearance space and ventilation.
Be sure to provide adequate clearance around the front and back of the racks. Provide at least 635 cm (25 in) in the
front of the rack to allow the doors to open fully and provide at least 762 cm (30 in) in the rear of the rack to allow for
servicing and airflow. If there are unused spaces in your rack, attach blanking panels across those empty spaces to
force the airflow through the components instead of through the open spaces.
3. Provide adequate and redundant sources of power.
Make sure that you have two high-line power feeds installed near your computer. These two power sources usually
come from the same external power grid, but occasionally might originate from dierent grids or even entirely
dierent sources. For protection against a power-source failure, obtain and include two uninterruptible power supplies
(UPS) in your installation. For a list of available UPS, see the Uninterruptible Power System website. For power
consumption specifications, see the HPE D3000 Enclosures QuickSpecs on the Accessing QuickSpecs website.
Confirming support for your hardware and software components
Specific versions of hardware, firmware, software, drivers, and other components are designed to work together. The HPE
D3000 Enclosures QuickSpecs available on the Accessing QuickSpecs website provides an up-to-date list of supported
servers, operating systems, controllers, switches, and software tools.
Procedure
1. Review the HPE D3000 Enclosures QuickSpecs to confirm that the components you plan to use are supported for use
with the disk enclosure. Download the quickspecs from the Accessing QuickSpecs website.
2. Review the QuickSpecs again before initially installing the disk enclosure and before making any changes to an
existing installation.
Preparing 5

Disk enclosure installation and configuration responsibilities
Storage management experience is required to successfully install and configure this product. If you are not familiar with
installing and configuring storage array systems, Hewlett Packard Enterprise can install this product for you. For more
information, see the Services website.
Dierent levels of assistance are available. For example, the following services might be included:
• Site inspection
• Verification of operating system patch levels
• Customized virtual disk design
• Array hardware installation and activation of optional software
• Array initialization
• Verification that the implemented solution meets your specifications.
• Availability of a Hewlett Packard Enterprise Services Storage Specialist to answer questions during the deployment
process.
• Verification testing to confirm product functionality and adherence to Hewlett Packard Enterprise installation quality
standards.
• On-site orientation, including highlights of basic operation and a review of documentation
Information gathering
A worksheet for system information is included in the quick setup instructions shipped with the disk enclosure. As you
gather and identify the hardware and software components for your environment, use the worksheet to record
information about your components and your configuration. Some information is easily obtained before installing the disk
enclosure, while some of the information is created during the configuration process. Information recorded on the
worksheet is helpful for future configuration changes and troubleshooting purposes. Also, Hewlett Packard Enterprise
recommends creating and keeping more detailed records.
NOTE: If a supplier is installing or configuring your disk enclosure, provide them with the quick setup instructions and
verify that they complete the worksheet and record other important configuration and setup information.
Registering with the HPE Email Preferences Center
The HPE Email Preferences Center website includes options to register for and automatically receive, by e-mail,
personalized product tips, update information, driver- and support-related advisories, and other notices for this and other
Hewlett Packard Enterprise devices. Although optional, Hewlett Packard Enterprise recommends registering all of your
Hewlett Packard Enterprise products.
Procedure
1. Go to the HPE Email Preference Center website.
2. Follow the onscreen instructions to select all of the Hewlett Packard Enterprise products for which you want to receive
notices. While subscribing, indicate your delivery preference (HTML, text, or RSS) and frequency of delivery (as they
become available, weekly, or monthly).
Preparing 6

Required installation tools
Items required for installation include the following, some of which ship with the disk enclosure:
• Rack mounting kit
• Disk enclosure
• Disk drives and drive blanks
• SAS controller or controller enclosure
• SAS cables
• Power cables
• Access to a workstation on the server
• Access to the Internet
NOTE: A variety of disk drives, SAS controllers, controller enclosures, and SAS cables are supported for use with this disk
enclosure. For more information, see the HPE D3000 Enclosures QuickSpecs available on the Accessing QuickSpecs
website .
Storage planning considerations
Proper planning of the system storage and its subsequent performance is critical to a successful deployment of the disk
enclosure. Improper planning or implementation can result in wasted storage space, degraded performance, or inability to
expand the system to meet growing storage needs.
Storage planning considerations include:
• System and performance expectations
• Striping methods
• RAID levels
• Disk drive sizes and types
• Spare drives
• Array sizing (capacity)
For the minimum supported configuration, and other configuration information, see the QuickSpecs for the disk enclosure.
System and performance expectations
To help determine the best way to configure your storage, rank the following three storage characteristics in order of
importance:
• Fault tolerance (high availability)
• I/O performance
• Storage eiciency
With priorities established, determine which striping method and RAID level to use; some configuration methods oer
greater fault tolerance, while other configuration methods oer better I/O performance or storage eiciency.
Preparing 7

Striping methods
There are two methods for configuring the physical layout of the disk arrays:
• Vertical striping—the RAID array uses one physical drive from each disk enclosure.
• Horizontal striping—the RAID array uses multiple drives contained within one or more disk enclosures.
RAID levels
Controllers use RAID technology to group multiple disk drives together in larger logical units (LUNs). Key RAID methods
include the use of data striping, data mirroring, and parity error checking. Data striping improves speed by performing
virtual disk I/O with an entire group of physical disks at the same time. Mirroring provides data redundancy by storing
data and a copy of the data. Parity error checking provides automatic detection and correction if corruption of a physical
disk occurs.
Depending on the host environment, the following RAID levels are supported with this disk enclosure:
RAID 0
RAID 0 is optimized for I/O speed and eicient use of physical disk capacity, but provides no data redundancy.
RAID 1
RAID 1 is optimized for data redundancy and I/O speed, but uses the most physical disk space.
IMPORTANT: RAID 1 uses about 100% more physical disk space than RAID 0 and 70% more than RAID 5.
RAID 5
RAID 5 protects against failure of one drive (and failure of particular multiple drives) of data. RAID 5+0 is a nested
RAID method that uses RAID 0 striping across RAID 5 arrays.
RAID 6
RAID 6+0 allows administrators to split the RAID 6 storage across multiple external boxes. RAID 6+0 requires a
minimum of eight drives. RAID 6+0 is a nested RAID method that uses RAID 0 block-level striping across multiple
RAID 6 arrays with dual distributed parity. With the inclusion of dual parity, RAID 6+0 will tolerate the failure of two
disks in each spanned array without loss of data.
RAID 6 with Advance Data Guarding (ADG)
RAID 6 with ADG allocates the equivalent of two parity drives across multiple drives and allows simultaneous write
operations.
• Distributed Data Guarding (RAID 5): Allocates parity data across multiple drives and allows simultaneous write
operations.
• Drive Mirroring (RAID 1 and 1+0 Striped Mirroring): Allocates half of the drive array to data and the other half to
mirrored data, providing two copies of every file.
Each level uses a dierent combination of RAID methods that impact data redundancy, the amount of physical disk space
used, and I/O speed. After you create a LUN, you cannot change the RAID level.
The following table compares the dierent RAID levels:
RAID level Data redundancy RAID method
RAID 0 None Striping
RAID 1 High Mirroring

High Striping and parity
RAID best practices
• RAID 0: Do not use LUNs if fault tolerance is required. Consider RAID 0 only for noncritical storage. RAID 0 LUNs
provide the best performance for applications that use random I/O.
• RAID 1: In general, RAID1 virtual disks provide better performance characteristics over a wider range of application
workloads than RAID 5.
• RAID 5: RAID 50 tolerates one drive failure in each spanned array without loss of data. RAID 50 requires less rebuild
time than single RAID 5 arrays RAID 50 requires a minimum of six drives.
• RAID 6: RAID 6 is most useful when data loss is unacceptable but cost is also an important factor. The probability that
data loss will occur when an array is configured with RAID 6 is less than it would be if it was configured with RAID 5.
However, write performance is lower than RAID 5 because of the two sets of parity data.
• RAID 6 with Advance Data Guarding (ADG): Organizations implementing a large drive array should consider RAID 6
because it can tolerate up to two simultaneous drive failures without downtime or data loss.
Disk drive sizes and types
RAID arrays should be composed of disk drives of the same size and performance capability. When drives are mixed within
a disk enclosure, the usable capacity and the processing ability of the entire storage subsystem is aected.
For example, when a RAID array is composed of dierent-sized drives, the RAID array defaults to the smallest individual
drive size, and capacity in the larger drives goes unused.
Spare disks
Spares are disks that are not active members of any particular array, but have been configured to be used when a disk in
one of the arrays fails. If a spare is present, it will immediately be used to begin rebuilding the information that was on the
failed disk, using parity information from the other member disks. During the rebuilding process, the array is operating in a
reduced state and, unless it is a RAID 6 or RAID 1+0 array, it cannot tolerate another disk failure in the same array. If
another disk fails at this time, the array becomes inaccessible and information stored there must be restored from backup.
After the rebuild of the data onto the spare is completed, when a replacement drive is inserted to replace the failed drive,
the system will automatically transfer the data from the spare onto the replacement drive and return the spare to an
available-spare state. It is important to note that the process of rebuilding the spare or the replacement drive must not be
interrupted or the process will be aborted. Some administrators have multiple spare disks, so that multiple arrays can
experience failure and successfully recover, before administrative intervention would be required to replace the spare or
failed disk. When assigning a spare to an array, the administrator chooses which arrays and how many arrays are
protected by that spare.
Array sizing
As a general rule, the greater the number of drives that are included in an array, the greater the performance level that
can be achieved. However, performance considerations are oset by fault tolerance considerations. The greater the
number of drives in an array, the higher the probability of one or more disk failures in that array. The administrator must
strike a balance between performance and fault tolerance.
Preparing 9

Warranty support and services
The standard warranty protects against product defects and some causes of downtime. You can extend your warranty
with HPE Care Pack Services. This portfolio of predefined packages is flexible, allowing you to extend coverage to the
exact level of support required. You choose the support level that meets your business requirement, from basic to
mission-critical. Recommended service levels and appropriate related services for your particular disk enclosure model are
listed on the QuickSpecs.
For more information, see the Storage Consulting Services website.
Deployment types
Single domain
In a single domain deployment, one path exists from the disk enclosure to the host. In a single domain deployment,
only one I/O module in the disk enclosure is used.
Dual domain
In a dual domain deployment, two paths exist from the disk enclosure to the host. In a dual domain deployment, both
I/O modules in the disk enclosure are used. Because dual domain deployments provide two paths to the storage,
access is ensured, even in the event of device, cable, or power failure. In dual domain environments, dual-port disk
drives are required.
Server attached (single or dual domain)
In a server attached deployment, the disk enclosure is connected to a controller card installed in a server. Several
models of controller cards are supported for use with this disk enclosure. For more information, see the QuickSpecs
for the disk enclosure.
Controller enclosure attached (single or dual domain)
In a controller enclosure attached deployment, the disk enclosure is connected to a rack-mounted array controller
enclosure. The controller enclosure is then connected to the server or network. Several models of array controller
enclosures are supported for use with this disk enclosure. For more information, see the QuickSpecs for the disk
enclosure.

Installing
Installation overview
Procedure
1. Review disk enclosure racking guidelines.
2. Review rack installation best practices.
3. Install the rack.
4. Install disk drives in the enclosure.
5. Install SAS controllers or controller enclosures.
6. Prepare the server.
7. Connect SAS cables and power cords.
8. Power the disk enclosure.
9. Verify the operating status of the disk enclosures.
Disk enclosure racking guidelines
The disk enclosure can be installed into most standard server racks. To verify that your rack is supported for use with the
disk enclosure, see the see the HPE D3000 Enclosures QuickSpecs on the Accessing QuickSpecs website.
• Install disk drives in the enclosures only after mounting the enclosures in the rack.
• A disk enclosure populated with disk drives is too heavy to lift safely.
• Movement of a disk enclosure during installation might damage the internal storage media of installed disk drives.
Rack installation best practices
In addition to industry-standard recommendations, consider the following:
• Locate the heaviest items, such as uninterruptible power supplies (UPS) and additional disk enclosures near the
bottom of the rack.
• To make cabling easy, install the disk enclosures below the server.
• Install similar components next to each other in the rack. Because disk enclosures, switches, and servers are of
diering depths, if you have more than one of a device, mount those devices adjacent to one another to accommodate
working behind the rack.
Installing 11

WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
• At least two people lift the storage system during removal or installation if the weight exceeds 227 kg (50 lb).
If the system is being loaded into the rack above chest level, a third person MUST assist with aligning the
system with the rails while the other two people support the weight of the system.
• The leveling jacks on the rack are extended to the floor.
• The full weight of the rack rests on the leveling jacks.
• The stabilizing feet are attached to the rack if it is a single-rack installation.
• The racks are coupled together in multiple-rack installations.
• Only one component in a rack is extended at a time. A rack might become unstable if more than one component
is extended.
• To prevent damage and to ease insertion of the device into the rack, support the weight of the device and keep
it level when sliding it into the rack.
Installing the rack
Procedure
1. Position left and right rack rails at the wanted 'U' position in the rack, adjusting the rails to fit the rack, as needed.
Front and Rear bottom edge of the rails must align with the bottom of EIA boundary in the lowermost 'U'. Front and
Rear bottom edge of the rails must align with the bottom of EIA boundary in the lowermost 'U'
2. Use guide pins to align the shelf mount kit to the RETMA column holes. The bottom of the rail must align with the
bottom of the U.
3. To engage the rear, push the rail toward the back of the rack until the spring hook (1) snaps into place.
4. To engage the front, pull the rail towards the front of the rack to engage the spring hook with the RETMA column in
the same manner as the rear spring hook.
NOTE: Make sure that the respective guide pins for the square or round hole rack align properly into RETMA column
hole spacing.
5. Secure rear of rack rail to the RETMA column with either the square-hold or round-hole shoulder screws, provided in
the plastic accessory bag.

Disk drive guidelines
• Follow industry-standard practices when handling disk drives. Internal storage media can be damaged when drives are
shaken, dropped, or roughly placed on a work surface.
• When installing a disk drive, press firmly to make sure the drive is fully seated in the drive bay and then close the latch
handle.
• When removing a disk drive, press the release button and pull the drive only slightly out of the enclosure. Then, to
allow time for the internal disk to stop rotating, wait approximately 10 seconds before completely removing the drive
from the enclosure.
• Always populate hard drive bays starting with the lowest bay number. If only one hard drive is used, install it in the
bay with the lowest device number.
• Disk drives are hot-pluggable.
• SAS and SATA disk drives may be installed in the same enclosure, but can not be included in the same RAID logical
volume.
Installing a disk drive
Prerequisites
CAUTION: To prevent improper cooling and thermal damage, operate the enclosure only when all bays are
populated with either a component or a blank.
Procedure
1. Remove the drive blank.

3. Determine the status of the hard drive.
CAUTION: For proper airflow and cooling, a drive blank must remain installed in all unused drive bays.
Installing SAS controllers or controller enclosures
For detailed installation and configuration information about controller cards or controller enclosures, see the
documentation provided with the controller card or controller enclosure.
Procedure
1. Record information about the controller or controller enclosure that will connect to the disk enclosure.
2. Depending on your deployment, do one of the following:
• For server connect deployments, install one or more Smart Array controllers in the server that will access the disk
enclosure.
• For controller enclosure connect deployments, install or locate the controller enclosure to which the disk enclosure
will connect.
Preparing the server
Procedure
1. Record information about the server and environment (server connect or controller enclosure connect) that will
connect to the disk enclosure.
2. Verify that the servers, controllers, operating system version, and service packs are supported for use with the disk
enclosure. For more information, see the HPE D3000 Enclosures QuickSpecs on the Accessing QuickSpecs website.
3. Install all operating system-specific service packs, patch kits, or other required tools.
4. Install Hewlett Packard Enterprise system management and monitoring tools, such as HPE Systems Insight Manager
(HPE SIM) and the Array Configuration Utility (ACU).
For detailed installation and configuration information about the server or the software tools, see the documentation
provided with the server or software.
Installing 16

Connecting SAS cables and power cords
IMPORTANT: The cabling figures in the following cabling topics demonstrate connecting a disk enclosure to a
server with an installed controller. In your environment, the disk enclosure might connect to a controller enclosure,
which then connects to the host or network. Cabling restrictions may exist for the dierent installation
environments. For more information, see the user documents for your controller or controller enclosure.
Cabling best practices
• Use supported SAS cables and power cords. A variety of cables and cable lengths are supported for use with this disk
enclosure. For more information, see the HPE D3000 Enclosures QuickSpecs on the Accessing QuickSpecs website.
• Use the shortest possible cable between devices. Shorter cables reduce the possibility of signal degradation that might
occur over longer distances. In addition, shorter cables are easier to manage and route along the back of the rack.
• Gather cables in the rear of the disk enclosure to ensure that the cabling in the back of the rack system does not
interfere with system operation or maintenance. Bind cables loosely with cable ties and route the cables out of the
way, along the side of the rack. When the cables are tied together and routed down the side of the rack, system
components and indicators are easily visible and accessible.
• Bind and support cables in a manner that eliminates stress on connectors and tight bends of the cables. This prevents
damage to the connector and cable, and ensures that the connector remains fully seated in the port.
• Attach a label near both ends of each cable to identify the device connected to that cable. Include the device, device
name, port, or other useful information.
• Use colored markers to color code both ends of each cable, to help visually identify a particular cable without having to
read or locate the label.
• In multipath configurations, you might want to loosely bind the matching pair of cables connecting devices.
Cabling guidelines–disk enclosure to server or controller enclosure
IMPORTANT: When connecting this disk enclosure in a single-domain environment, only the top I/O module (I/O
module A) in the disk enclosure is supported for use.
• Only use supported SAS cables with mini-SAS connectors.
• Ensure that the servers or controller enclosures are powered down and power cords are disconnected before
connecting SAS cables to the disk enclosure.
• P1 on the disk enclosure I/O module is treated as the SAS “in” port.
• P2 on the disk enclosure I/O module is treated as the SAS “out” port.
• In single-domain configurations, one cable path is created between the host, the primary disk enclosure, and additional
cascaded disk enclosures.
• In dual-domain configurations, two cable paths are created between the host, the primary disk enclosure, and
additional cascaded disk enclosures.
In your environment, the disk enclosure might connect to a controller enclosure, which then connects to the host or
network. Regardless of environment, cabling principles from the disk enclosure to the host are the same.

Cabling guidelines–disk enclosure to disk enclosure
• To cascade additional disk enclosures from the disk enclosure that is connected to the server or controller enclosure,
use standard mini-SAS cables.
• As additional disk enclosures are connected to the first disk enclosure, they are assigned a box number. The assigned
box number is displayed on the 7-segment display on the rear of the disk enclosure.
• When connecting this disk enclosure in a single-domain environment, only the top I/O module (I/O module A) in the
disk enclosure is supported for use.
• The number of supported cascaded disk enclosures varies per disk enclosure model and installation environment. For
more information, see the QuickSpecs for the disk enclosure, controller, or controller enclosure, available on the
Accessing QuickSpecs website.
• Only use supported SAS cables with mini-SAS connectors.
• Use provided color clues on the disk enclosure when cabling cascaded disk enclosures; for example, connect “green”
ports to “green” ports (connect I/O module A on one disk enclosure to I/O module A on the additional disk enclosure).
• P1 on the disk enclosure I/O module is treated as the SAS “in” port.
• P2 on the disk enclosure I/O module is treated as the SAS “out” port.
• In single-domain configurations, one cable path is created between the host, the primary disk enclosure, and additional
cascaded disk enclosures.
• In dual-domain configurations, two cable paths are created between the host, the primary disk enclosure, and
additional cascaded disk enclosures.

Power cord guidelines
When connecting power cords, use the cords shipped with the disk enclosure. The power cord should be approved for use
in your country. The power cord must be rated for the product and for the voltage and current marked on the electrical
ratings label of the product. The voltage and current rating for the cord should be greater than the voltage and current
rating marked on the product. In addition, the diameter of the wire must be a minimum of 100 mm2 or 18 AWG, your
maximum length may be up to 366 m (12 ft).
After power is supplied to the disk enclosure, the power supply automatically senses the input voltage and the power
supply LED illuminates as solid green. To protect the system from power-failure-related downtime, each disk enclosure
ships standard with a redundant power supply. Depending how you connect the power supplies to the power source, you
can eliminate downtime caused by power-related failures.

Connection method Level of protection
One power source Protects you from downtime when one of the disk enclosure power supplies fails. The
remaining power supply/fan module can operate the disk enclosure until you install a
replacement module.
Two separate power sources Protects you from downtime when one of the disk enclosure power supplies fails.
Protects you from data loss when one of your power sources fails, due to a pulled cable or
tripped breaker.
The remaining power source can power the disk enclosure until the failed power source is
restored or relocated. Depending on the cause and duration of the power outage, you can
use this time to properly shut down your storage sub-system.
Two UPS
Two separate power sources
Protects you from downtime when one of the disk enclosure power supplies fails.
Protects you from data loss when one or both of your power sources fails, due to apulled
cable, tripped breaker, or local power outage.
The remaining power source or the UPS will power the disk enclosure until power is
restored to the source. Depending on the cause and duration of the power outage, you
can use this time to properly shut down your storage sub-system.
WARNING: To reduce the risk of electric shock or damage to the equipment:
• Do not disable the power cord grounding plug. The grounding plug is an important safety feature.
• Plug the power cord into a grounded (earthed) electrical outlet that is easily accessible at all times.
• Route the power cord so that it is not likely to be walked on or pinched by items placed against it. Pay particular
attention to the plug, electrical outlet, and the point where the cordis attached to the disk enclosure
Powering the disk enclosure
IMPORTANT: Always power on disk enclosures before controller enclosures and servers. This ensures that servers,
during the discovery process, identify the enclosures and installed disk drives as operational devices.
Powering on disk enclosures
Prerequisites
• Complete the server, controller, or controller enclosure installation.
• Install the disk enclosures.
• Install disk drives in the disk enclosures so that the connected host controller can identify and configure them at
power-on.
• Connect the SAS cables and power cords to the enclosure.
Procedure
1. Apply power to each UPS, or connect the enclosure to a live power source.
