Install the HPE Nimble Storage Array
There are several steps to install the HPE Nimble Storage array, such as providing a suitable operating
environment, installing the array into your rack, and making network connections appropriate to your current
and anticipated topologies. After the array has been configured, you can perform maintenance and upgrade
tasks as needed.
Network Considerations
In preparation for installing your HPE Nimble Storage array, information in this section will help you:
•Determine your network topology
•Plan for the configuration of IP Addresses
•Identify options for subnets, including (for iSCSI):
• Discovery IP addressing
• IP address zones
• Traffic assignments
•Understand data connections to your iSCSI or Fibre Channel array through Interface Pairs
Use the Installation Checklist to note all information required before installing your array. For more information,
refer to the GUI Administration Guide or the CLI Administration Guide.
Network Topology
When you initially configure the arrays, you are prompted to choose a network topology. The selection that
you make enables the setup wizard to assist in making the optimal networking choices:
• One shared network
• Two dedicated networks
• Advanced network configuration
• Dual Fabric Fibre Channel
Important The following diagrams are conceptual examples of the network connections you might use for
each topology. These diagrams are not intended to show a complete set of connections.
One Shared Network
In this configuration, the management and data traffic share the same physical network interfaces. If more
than one switch is used in this configuration, the switches must be connected to each other by an inter-switch
link or trunk port, or they must be configured in a single switch stack if supported by the switch manufacturer.
You may want to consider this configuration if you have only one network or if your data traffic is low enough
that adding management traffic does not affect the LAN.

Two Dedicated Networks
In this configuration, management traffic and data traffic are separated into two subnets. Management traffic
uses the ports assigned to the management subnet. All other subnets are designated as data only. Two
switches for the management traffic and two switches for the data traffic are recommended for redundancy
and high availability. Multiple switches carrying a particular subnet must be connected with an inter-switch
link, trunk port, or switch stacking modules. If that subnet is assigned to a particular VLAN, the inter-switch
link or trunk port must allow that VLAN.
This configuration option is probably best in cases where security is an issue, where network administrators
do not need access to data traffic, where the amount of data traffic is such that it has a dedicated network,
or where the network for data traffic is completely separate from the management network.
Choose this option:
• To limit iSCSI traffic to 10Gb interfaces
• To isolate the subnets for network security
• If you want a dedicated broadcast domain reserved for iSCSI traffic

Advanced Network Configuration
From the Advanced and advanced multipath requirements selection of the setup wizard, you can define
a configuration for a dedicated management port or define any number of ports to handle the desired I/O
flow. The advanced network configuration allows the greatest flexibility to suit your network traffic and advanced
multipath requirements.
This particular example shows the management and data paths on different networks. Data ports are connected
to subnets that carry iSCSI traffic, and you can add more data connections to additional ports as needed.
Note that the subnet addresses in the illustration are just examples. This arrangement enables the maximum
data throughput by isolating management traffic from the data.

Dual Fabric Fibre Channel
In this configuration, two Fibre Channel ports on a host HBA are connected to two separate Fibre Channel
switches, with each Fibre Channel switch connected to both controllers on the array. The host management
port and the controller management ports are connected through an Ethernet switch.
This configuration provides redundant paths for Fibre Channel traffic. If one of the host Fibre Channel ports
fails, or one of the Fibre Channel switches fails, the host remains connected to both controllers through the
remaining host Fibre Channel port or Fibre Channel switch, and Fibre Channel traffic continues uninterrupted.
Note that only one data connection is shown. You can add more connections and use different ports as
needed.

IP Addresses
An IP address is a 32-bit identifier for devices on a TCP/IP network. IP addresses allow devices on a network,
such as servers, switches, and arrays, to communicate with each other. HPE Nimble Storage arrays use IP
addresses for the following purposes:
Table 1: Types of IP addresses
PurposeIP Address
Typically defined on eth1 or on eth1 and eth2 interface, the management IP address
provides access to the NimbleOS management interface (GUI, CLI, or API) for the array
group. It is also used for volume replication. It resides on the group management subnet
and floats across all management only (Mgmt only) and management + data (Mgmt +
Data) interfaces.
Management

IP Addresses

PurposeIP Address
For iSCSI arrays, each subnet has its own discovery IP address. It enables the iSCSI
initiator to discover iSCSI targets for the volumes on the array. You can use this IP address
for data as well as management in a single shared network.
Note Discovery IP addresses are not required for Fibre Channel arrays.
Discovery
One or more IP addresses can be configured to carry data traffic. One data IP address
can be configured for each interface pair (corresponding interfaces on the two controllers).
Both controllers use the same IP address but never at the same time because only one
controller is active at a time. Other data IP addresses can be configured on different
subnets.
Note In a dedicated network topology, the data IP addresses cannot be the same as the
management/iSCSI discovery IP addresses.
Data
Each controller on an array must have a dedicated support IP address, which can be
used for troubleshooting and technical support purposes in the event that a controller is
not reachable through the management IP address. The support IP addresses must be
placed on the group management subnet.
Support
Subnets
A subnet is logical subdivision of a network. It is defined by the first IP address in the network and a netmask
that specifies a contiguous range of IP addresses within that network. A subnet can be assigned to one or
more network interfaces.
The maximum Transmission Unit (MTU) can be set for a subnet so that it uses either a standard, jumbo, or
custom frame size. If you choose to use a custom frame size, you must specify the size in bytes.
Specifying a VLAN ID on a subnet allows more than one subnet to be assigned to an interface using IEEE
802.1Q tagged frames. Subnets without a VLAN ID can only have untagged assignments. Switch port
configurations must match the VLAN IDs configured on the subnets for tagged assignments. For more
information, refer to the procedure to Configure VLAN Tagging in the GUI Administration Guide or CLI
Administration Guide.
Subnet Traffic Types
Traffic types are used to segregate network traffic into different subnets. A subnet can carry one of the following
traffic types.
Table 2: Traffic Types

The subnet carries only management traffic.Management
(Mgmt only)

Subnets

Subnet Traffic Assignments
Traffic assignments determine what type of iSCSI traffic a data subnet carries. You can assign a data subnet
on an iSCSI array to carry one of the following kinds of traffic.
Note Traffic assignments are not required for Fibre Channel arrays.
Table 3: Traffic Assignments
DescriptionTraffic Assignment
The subnet carries both iSCSI data traffic and intra-group communication (traffic
between arrays in a group).
iSCSI + Group
The subnet carries only iSCSI data traffic.iSCSI only
The subnet carries intra-group communication traffic.Group only
IP Address Zones in Subnets
An IP address zone is a group of host IP addresses and array data IP addresses in a subnet. When using
two switches for iSCSI traffic, hosts can achieve better performance by establishing iSCSI connections with
data IP addresses inside the same zone, as opposed to establishing iSCSI connections with data IP addresses
in a different zone.
Note IP address zones are not required for Fibre Channel arrays.
The IP addresses within a subnet can be divided into IP address zone types.
Table 4: IP Address Zone Types
DescriptionZone Type
Used for non-iSCSI enabled subnets.None
All IP addresses are in one zone. This is the default zoning setting.
With two network switches, iSCSI connections can be routed over the inter-switch link.
Single
One zone includes the IP addresses from the top half of the subnet; for example,
192.168.1.128 to 192.168.1.254. The other zone takes the IP addresses from the bottom
half of the subnet; for example, 192.168.1.1 to 192.168.1.127
Bisect
The IP addresses are grouped by their last bit. One zone includes the even-numbered IP
addresses, such as 192.168.1.2, 192.168.1.4, 192.168.1.6, and so on. The other zone in-
cludes the odd-numbered IP addresses, such as 192.168.1.1, 192.168.1.3, 192.168.1.5,
and so on.
Even/Odd
IP address zones are useful for configurations that use two switches, where you want to establish connections
that avoid the Inter-Switch Link. For IP address zones to work, the host and the array must have their data
IP addresses configured with half of their IP addresses from one zone connected to one switch and the other
half of its IP addresses from the other zone connected to the other switch. For example, assume that:
• There is a single subnet, 192.168.1.0/24.
• There are two zones, defined as Red and Blue.
• Red zone consists of:
• Host IP 192.168.1.1
• Array Data IP 192.168.1.3
• Array Data IP 192.168.1.5
• Blue zone consists of:

Subnet Traffic Assignments

Host IP 192.168.1.2•
• Array Data IP 192.168.1.4
• Array Data IP 192.168.1.6
In the IP Address Zone, the host IP addresses in the Red zone only establish connections with the data IP
addresses in the Red zone. And the host IP addresses in the Blue zone only establish connections with the
data IP addresses in the Blue zone. In this way, iSCSI connections do not use inter-switch link and thereby
maximize I/O performance.

Interface Pairs
Nimble uses the term interface to identify specific ports on the controller. For iSCSI, an interface is an Ethernet
port connection that can be used for data, management, or both; for Fibre Channel, an interface is a Fibre
Channel port connection that can be used for data only.
The purpose of interface pairs is to ensure high availability and redundancy in the event of a controller or
network switch failure. In the event of a controller failover, proper network connections ensure minimal data
service interruption.
To minimize single points of failure, connect as many interface port pairs as possible.
iSCSI Interface Pairs
An iSCSI interface pair refers to a set of two data or management Ethernet connections, one from each
controller, to the network switch. The cables for an interface pair connect to the same data or management
port on each controller. See Interface Numbering on page 16.

An interface pair is the combination of the same data port on both controllers. In the preceding diagram:
• Data ports eth2a form one interface pair (red)
• Data ports eth2b form another interface pair (blue)
Make sure that each interface pair connects to the SAME network or subnet. In this example, the red interface
pair connects to subnet 1 and the blue connects to subnet 2.
Fibre Channel Interface Pairs
A Fibre Channel interface pair refers to a set of two Fibre Channel data connections, one from each controller,
to the Fibre Channel switch. The cables for an interface pair connect to the same data port on each controller.

Rack Mount Safety Precautions
Observe these safety precautions when you install the HPE Nimble Storage array or expansion shelf in a
rack.
Table 5: Rack Mount Safety Precautions
PrecautionConsideration
If the array or expansion shelf is installed in a closed or multi-unit rack assembly, the op-
erating temperature might be greater than the ambient (room) temperature. Provide ade-
quate cooling so the rack environment does not exceed 35°C (95°F) as specified by the
rack manufacturer.
Elevated Operat-
ing Temperature
Install the equipment in the rack such that each item has ample air flow required for
proper cooling.
Cold air comes into the front of the array (drive side) and is exhausted out the back of the
array (controller side) by the fans. Install the array with the front facing the cold aisle and
the back facing the hot aisle in your environment.
Air Flow
Mount the equipment so that the mechanical loads on the rack are even top-to-bottom,
front-to-back, and side-to-side.

Rack Mount Safety Precautions

PrecautionConsideration
Be sure there is adequate power service to prevent overloading the circuits. Check the
ratings of each item of equipment on each circuit.
Note The power supplies are 220VAC or 110VAC auto-detecting.
Circuit Overload-
ing
You must provide reliable grounding (earthing) of rack-mounted equipment. In addition,
pay attention to supply connections from the branch circuit, such as power strips.
