Introduction

Pluribus Networks' UNUM™Unifi ed Management, Automation, and Analytics Platform Software is an

application portal developed by Pluribus Networks.

UNUM enables the network administrator to extract analytical value from the telemetry data reported by

the network switches powered by the Pluribus Networks Netvisor®ONE network operating system.

Once data is collected, UNUM relies upon a modern search engine database infrastructure to store,

aggregate, filter, correlate, and visualize vast amounts of data in real-time as well as with a powerful time

machine functionality.

The UNUM portal provides a collection of feature-rich applications that manages and orchestrates the

gathering and presentation of network analytics using various types of collectors and reporting software.

The UNUM applications rely primarily on features of the Netvisor ONE, such as VFLOWs, mirrors, and

connections statistics, but can also provide analytics in a non-Pluribus environment.

At a high-level, UNUM supports the following deployment scenarios:

·Netvisor ONE as a mirror switch; an out-of-band Pluribus switch is configured as a

mirror in either an existing Pluribus-switched network or a non-Pluribus-switched

network.

·Netvisor ONE as an in-band switch; connection stats are pulled, and VFLOWs

configured on the switch.

Collectors gather network analytics and feed data into the UNUM analytics store(s):

·This collector is enhanced to use the vREST API to gather the analytics data from

Netvisor.

Physical Installation

Please refer to Server Installationsection in the Users Manual (MNL-1662). Follow the Manualslink at

the following location:

https://www.supermicro.com/products/system/2U/2028/SYS-2028TP-HTTR.cfm

Please review and follow all Warnings! outlined in the above documentation.

Hardware Overview

The 2RU Pluribus UNUM High Capacity Appliance is a unique server system. With four system boards

incorporated into a single chassis acting as four separate server nodes.

Server Nodes

Each of the four server boards act as a separate server node in the system.

As independent server nodes, each may be powered off and on without affecting the others.

In addition, each server node is a hot-swappable unit that may be removed from the rear of the chassis.

The server nodes are connected to the server back-plane by means of an adapter card.

Note: A guide pin is located between the upper and lower server nodes on the inner chassis wall. This

guide pin also acts as a stopwhen a server node is fully installed. If too much force is used when

inserting a server node this pin may break off. Take care to slowly slide a server node in until you hear the

clickof the locking tab seating itself.

Each Server node consists of:

Processors

Dual Intel® Xeon® E5-26x series processors.

Memory

Sixteen DIMM slots supporting 256 GB of ECC RDIMM (Registered DIMM) memory.

Serial ATA

A Serial ATA controller is integrated to provide dual 1.2 TB SSD Drives.

Warning: The SATA drives are physically hot-swappable units, however doing so during regular operation

results in loss of data in the Pluribus UNUM High Capacity Appliance.

Recommended Procedure: Under normal operation, power down the server node and data redistribute

across the nodes, and then the SATA drives can be safely removed without data loss.

Hardware Overview (cont'd)

Onboard Controllers/Ports

An Intel Gigabit (100/1000/10000 Mb/s) Ethernet dual-channel controller is included. Using an AOC Card

not a supported configuration.

I/O ports include a VGA (monitor) port, two USB 3.0 ports, an IPMI dedicated LAN port and two Ethernet

ports, Eth0 and Eth1. Eth0 is used for Management, Eth1 is used for internal server node to server node

communications.

Eth1 must be isolated from the public network.

Other Features

Other onboard features that promote system health include onboard voltage monitors, auto-switching

voltage regulators, chassis and CPU overheat sensors, server node manager software and BIOS rescue.

Server Nodes

Hardware Overview (cont'd)

Server Chassis Features

The following is a general outline of the main features of the appliance chassis.

System Power

Each chassis model includes redundant, hot-plug high-efficiency 80-plus Platinum certified power supplies,

rated at 2000 Watts. In the unlikely event your power supply fails, replacement is simple and can be

accomplished without tools. An amber light will be illuminated on the power supply when the power is off.

An illuminated green light indicates that the power supply is operating.

Cooling System

The chassis contains four system fans, which are powered from the back-plane.

Hardware Overview (cont'd)

Mounting Rails

The Pluribus UNUM High Capacity Appliance includes a set of quick-release rails, and can be placed in a rack

for secure storage and use. To setup your rack, follow the step-by-step instructions included in the SMCI

manual.

Server Chassis Features

System Interface

There are several LEDs on the control panel and on the drive carriers to keep you constantly informed of

the overall status of the system.

This chapter explains the meanings of all LED indicators and the appropriate response you may need to

take.

LED Indicators

Control Panel Button

Power

The main power button on each of the four control panels is used to apply or remove power from the power

supply to each of the four server nodes in the chassis.

The power button has a built-in LED which will turn green when the power is on.

Each of the four server nodes are powered on and off individually.

Powering off one server node does not affect the power of the other server nodes.

Turning power off with this button does not remove power from the chassis, hence caution must be used

when servicing.

UID

The UID button is used to turn on or off the blue light function of the LED.

Once the blue light is activated, the unit can be easily located in very large racks and server banks.

System Interface (cont'd)

Control Panel LEDs

The four control panels are located on the front handle of the chassis.

Each control panel has two additional LEDs.

These LEDs provide you with critical information related to different parts of the system.

This section explains what each LED indicates when illuminated and any corrective action you may need to

take.

Alert

This LED is illuminated when an alert condition occurs:

·A solid red light indicates an overheat condition in the system

·A flashing red light which fl ashes in one second intervals indicates a fan failure

·A flashing red light which flashes in four second intervals indicates a power failure

When notified of an alert, check the routing of the cables and make sure all fans are present and operating

normally.

You should also check to make sure that the chassis covers, and air shrouds are installed.

This LED will remain flashing or on as long as the temperature is too high, or a fan does not function

properly.

NIC

Indicates network activity on either LAN1 or LAN2 when fl ashing.

Drive Carrier LEDs

SATA Drives

Each drive carrier has two LEDs.

·Blue: When illuminated, this blue LED (on the front of the drive carrier) indicates

drive activity. A connection to the back-plane enables this LED to blink on and off

when that drive is being accessed

·Red: The red LED to indicate a hard drive failure.

Network Connections

After installation of the Pluribus UNUM High Capacity Appliance, network activity must be setup as follows

(please refer to the figure below for proper connections):

1. For proper operation the Pluribus UNUM High Capacity Appliance requires a separate 1G or 10G switch

for connectivity between eth1 on all Server nodes.

2. Connect your Management Network to Eth0 (1G or 10G) on Server node A. By default, Server node A

(Host) is confi gured for DHCP. To set a static IP, see Appendix A.

3. It is required to connect Eth1 into an isolated 1G or 10G switch. Server nodes will communicate via Eth1,

with the following IP Addresses:

a. 172.16.250.150 - 172.16.250.162

4. Plug in redundant power connections with the provided cables ONLY and power up.

Network Connections

Network Connections (cont'd)

NOTE: Eth1 connections are not configured on a VLAN, please contact Pluribus Technical support if one

of the following must occur:

·More than one Pluribus UNUM High Capacity Appliance plugged into the same switch (by default, all

appliances come with the same pre-configured Eth1 IP addresses), and each Appliance isolated in a

separate and dedicated VLAN.

·You want to change the default Eth1 IP Addresses of: 172.16.250.150 - 172.16.250.162.

5. Connect VGA console and IPMI as desired. IPMI default confi guration is DHCP.

6. USB connections are not advised.

7. The Pluribus UNUM High Capacity Appliance, comes with the Pluribus UNUM software pre-installed.

8. Upon boot up, by default Pluribus UNUM will use DHCP to obtain a Management / eth0 IP address. If a

Static IP is desired, see Appendix B.

9. It is highly recommended that the default root password of your Server nodes be changed from test123.

NOTE: It is required that all Server nodes have the same root password.

To change the root password of your Server nodes, you can do the following:

Network Connections (cont'd)

Log onto each Server node as root using the ESXi web client (or vSphere client if you have access):

VMware Welcome Screen

Network Connections (cont'd)

Select Change Password

VMware Change Password Dashboard

Enter New Password:

VMware Change Password

Network Connections (cont'd)

IMPORTANT: Repeat for each Server node, root passwords must be the same on each.

10. The Primary Server Node A, runs the Pluribus UNUM Web Interface.

You can find the IP of your Pluribus UNUM Primary VM via the ESXi web client (or vSphere client if you

have access), log in with the your newly set root password:

Pluribus UNUM Primary VM

In the above example, you will see the IP from your DHCP server, in this case it is 10.x.x.x, but the actual

IP will depend on your DHCP configurations.

11. Once you obtain the IP of your Pluribus UNUM, use a Chrome browser to connect for the best

experience.

HA Considerations - Cluster

Cluster / Data Node Health:

Green Cluster is fully operational with replicated data.

Yellow Cluster is fully operational data is being replicated.

Red Cluster is operational data has been lost.

Failure of any one Server Node B, C, or D:

Upon failure or removal of any one Server node B, C, or D, the Pluribus UNUM High Capacity Appliance will

redistribute data such that no data will be lost.

The Cluster will temporarily go to Yellow, then will recover to Green after data is fully redistributed.

Redistribution of data times will vary depending on system / traffi c load.

Normal operation can continue; however, the system is operating in a non-redundant configuration.

The failed or removed Server node, must be replaced as soon as possible.

Failure of more than one Server Node B, C, or D:

Upon failure or removal of more than one Server node B, C, or D will likely result in permanent data loss.

Two of the three Server nodes B, C, and D must be operational for the system to collect, manage and store

data properly.

Upon data loss the Cluster status will likely go Red and require replacement of failed or removed Server

nodes until at a minimum, two of the three are replaced.

Failure of Server Node A:

Upon failure or removal of the Primary Server node A, data will not be lost, however data collection and

connectivity to Pluribus UNUM will stop.

The Primary Server node A must be replaced as soon as possible for normal operation to resume.

Replace a Failed Cluster Server

Data Server Node Replacement

One symptom of a failed Data Server Node is the appearance of offline nodes in the UNUM System Health

dashboard as shown in the example below.

In the example, UNUM displays single ESXi instance with 4 data nodes, all offl ine.

UNUM System Health Dashboard - Cluster

In the event of a Cluster Server failure and you have received a replacement Server from Pluribus

Networks please use the following instructions to rebuild the Cluster.

Note: The replacement Server you receive has VMware ESXi installed. You need to add the Server to the

Cluster using the cluster_menu.sh configuration script.

Note: All Server Nodes must be connected via the Eth0 Ethernet interface.

1. Login into the Remote Console of a Primary VM instance with your login credential. If you have not

changed the default credentials the username and password is “vcf”and the password is “changeme”.

The UNUM Cluster setup script is named “unum_provision.sh”and is located in the default folder

“/home/vcf/srv/vcf/bin/tools/cluster”.
