Introduction (cont'd)
Arista NetVisor UNUM enables the network administrator to extract analytical value from the telemetry
data reported by the network switches powered by the NetVisor OS network operating system.
Once data is collected, Arista NetVisor 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 Arista NetVisor 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 OS, such as vFLOWs, mirrors, and
connections statistics, and can also provide analytics in a non-Arista environment.
At a high-level, Arista NetVisor UNUM supports the following deployment scenarios:
· NetVisor OS as a mirror switch; an out-of-band switch is configured as a mirror in either an existing
Arista-switched network or a non-Arista-switched network.
· NetVisor OS as an inband switch; stats are pulled directly from configured switches such as
connections, vports, ports, tunnels and, vflow-stats.
· Collectors gather network analytics and feed data into the Arista NetVisor UNUM analytics store(s):
§The Collector uses the vREST API to gather the analytics data from NetVisor OS.
Arista NetVisor UNUM manages the following applications:
· Common Infrastructure – a centralized portal launches other applications, provides authentication to
the corporate directory (using LDAP), and provides configuration of standard settings.
· Insight Analytics – this application provides reporting and Search capabilities on data collected from
Arista NetVisor UNUM collectors.
· Switch Analytics – Switch Analytics contains a feature-rich set of management tools providing Traffic
Monitoring and Notification services with exceptional drill-down capabilities.
· Fabric Manager – Fabric Manager contains a feature-rich set of management tools providing
configuration tools for Layer 1, Layer 2, and Layer 3 services as well as Security, Monitoring, Analytical,
and Service features.

Hardware Overview
High Capacity Appliance Hardware Overview
The 2RU Arista NetVisor 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 Arista NetVisor 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.

System Interface
High Capacity Appliance 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 flashes 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 flashing.
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.
