1Avid NEXIS System Overview
The Avid NEXIS system is a shared storage solution for acquisition, creative, distribution, and archive media
workflows. Avid network storage systems are built for media and entertainment. They enable multiple clients to
share, capture, play, and edit video and audio media.
Clients access Avid NEXIS systems through external switch connections. The Avid NEXIS Management Console
provides workspace and system management functionality.
This chapter provides an overview of the Avid NEXIS system and the basic function of each component. Other
chapters in this guide describe how to install the system in a rack, connect the power and Ethernet cables, and
configure the system.
Avid NEXIS Configurations
The Avid NEXIS system is available in the following hardware configurations.
Avid NEXIS | E2
The Avid NEXIS | E2 is a 2U Engine with one Avid NEXIS | E2 Controller, two 764W power supply/cooling
modules (PCMs), two solid state system drives (400GB), and one Media Pack (see “Media Packs” on page 2).
The Avid NEXIS | E2, with the Avid NEXIS | FS Foundation license, can function as both a storage engine and a
System Director for itself and up to four Media Packs, and up to 40 clients. To manage more than four Media
Packs in the same shared storage system, you must deploy a System Director Appliance (see “System Director
Appliance” on page 2), which takes over the System Director functions and provides no media storage.
Avid NEXIS | E4
The Avid NEXIS | E4 is a 4U Engine with one Avid NEXIS | E4/SDA Controller, and four 580W power supply/
cooling modules. The Engine has 24 drive slots; two are reserved for the solid state system drives (400GB). The
remaining slots support up to two Media Packs (see “Media Packs” on page 2), and two spare media drives.
Empty drive slots must be covered with blank plates to maintain proper airflow and cooling.
The Avid NEXIS | E4, with the Avid NEXIS | FS Foundation license, can function as both a storage engine and a
System Director for itself and up to four Media Packs, and up to 40 clients. To manage more than four Media
Packs in the same shared storage system, you must deploy a System Director Appliance (see “System Director
Appliance” on page 2), which takes over the System Director functions and provides no media storage.
System Director Appliance
The System Director Appliance is a 2U server built from common hardware modules as other Avid NEXIS
products. It contains one Avid NEXIS | E4/SDA Controller, two 764W power supply/cooling modules, and two
solid state system drives (400GB). The System Director Appliance does not provide media storage; the unused
drive slots are covered with blank plates. It runs the System Director for one or more Avid NEXIS engines that
collectively contain up to 24 Media Packs, with one of the following licenses:
•A vid NEXIS | FS Extended license — Supports a System Director Appliance managing up to 12 Media Packs
and up to 165 clients, with any combination of Avid NEXIS Engines in the same shared storage system.
•A vid NEXIS | FS Advanced license — Supports a System Director Appliance managing from 13 to 24 Media
Packs and up to 330 clients, with any combination o f Avid NEXIS Engines in the same shared storage system.
Media Packs
A Medi a Pack is a set of 10 drives, all of which are either 2 TB or 6TB, yieldin g a Media Pack capa city of 20TB or
60TB.
System Details
The Engines and the System Director Appliance are described in more detail in the following sections.
Engine
The Engine is a rack-mountable unit housing the other system components (drives, power supplies). If a
component fails, the system is designed to remain operati onal while you replace it. Do not shut down an Engine or
the System Director Appliance before replacing a failed part.
Data passes between the Engine and clients through a switch connected to the Engine with one or more 10 Gb
Ethernet connections. These connections provide clients access to the data on the media drives.
Avid NEXIS | E2 Engine Front
The front of the Avid NEXIS | E2 has a removable bezel (not shown). Removing the bezel allows access to the
drive slots. The Avid NEXIS | E2 supports one Media Pack (10 drives) for media storage and two system drives.
As shipped from Avid, the system drives occupy the first two slots in the Engine (0 and 1). Drive slot numbering
is shown below.

Controller Release LatchTo remove the controller from the Engine (see “Replacing a Controller” on page 33)
10GbE PortsConnect to a network switch (see “Connecting the Hardware to a Switch” on
System Director
The System Director maintains all information about the file system. The System Director is either embedded on
a Controller in an Avid NEXIS | E2 or Avid NEXIS | E4 Engine, or runs separately on a System Director
Appliance. In a multi-Engine Avid NEXIS storage system, there can be only one System Director. If the System
Director is embedded, the first Engine configured in a multi-Engine system runs the System Director for the entire
system.
The embedded System Director can manage up to four Media Packs, in any combination of Avid NEXIS | E2 and
Avid NEXIS | E4 Engines.
The System Director Appliance can manage up to 24 Media Packs, in any combination of Avid NEXIS Engines,
with either the Avid NEXIS | FS Extended license (for up to 12 Media Packs) or the Avid NEXIS | FS Advanced
license (for between 13 and 24 Media Packs).
•Storage Controller | 10 for Avid NEXIS | E2
•Storage Controller | 20 for Avid NEXIS | E4 and the System Director Appliance

The System Director:
•Manages the metadata by storing directory information and file attributes.
•Provides a location to coordinate fil e access modes (read/write ), file locking , range lock ing, performance data
collection, logging, file lookup, and directory change tracking for client systems.
• Provides the following information:
-Identity of all connected storage systems
-Information about the drives, power, cooling and Controllers in the configuration
-Names of workspaces
-Lists of users and groups within the system
The System Director does not store client data (media files); these are stored on the Media Packs (drives) within
the Engine. System Director metadata is mirrored on the system drives in the Engine, or on the system drives in
the System Director Appliance.
System Directors, workgroup servers, and clients must all be synchronized with a common time of day. For
information on setting the Network Time Protocol (NTP), see “Software Installation and System Setup” on
page 17.
Media Pack and System Drives
The Avid NEXIS Engines contain varying numbers of M edia Packs, 10 driv es per pack. As shipped from Avid, all
the drives in a single Media Pack are either 2TB or 6TB. The System Director Appliance contains no Media
Packs, as it is not used for client data storage.
When replacing a failed drive in a Media Pack, make sure to use a drive of the same capaci ty as, or lar ger than, the
others in the Media Pack. For more information, see “Replacing a Drive” on page 31 and the Avid NEXIS Administration Guide.
Each Engine and System Director Appliance has two system drives, of 400GB capacity. The System Director,
whether running on an Engine or in the System Director Appliance, uses the system drives for metadata, startup
files, and other system files. The Engine or System Director Appliance can run with one failed system drive. Avid
recommends replacing it as soon as possible.
The system drives typically occupy slots 0 and 1, and the Media Pack drives typically use the remaining slots.
To distinguish between the types of drives:
•System drives are labeled similar to the following, indicating the capaci ty, the letters SS for solid state, and a
manufacturer serial number:
•Media Pack drives are labeled simila r to the following, indicating the capacity (2TB or 6T B), the abbreviati on
7K2 indicating the drive speed (7200 rpm), and a manufacturer serial number:
7
System drives are physically 2.5” but are in a 3.5” carrier, like the Media Pack drives.
Avid NEXIS | E2 and Avid NEXIS | E4 Media Pack and System drives
The drives in the Avid NEXIS | E2 and Avid NEXIS | E4 Media Packs have a lock indicator and two LEDs that
show the drive status, explained in the following figure and table.

Leave failed drives in place until you have a replacement so you mainta in the proper airflow. Obtain a
replacement as soon as possible.
Power Supplies
Depending on your Avid NEXIS model, the Engine or System Director Appliance has the following number and
type of power supply/cooling modules (PCMs):
•Avid NEXIS | E2 and System Director Appliance — Two 764W PCMs (integrated fans)
•Avid NEXIS | E4 — Four 580W PCMs (integrated fans)
The power supplies are turned on when the power cord is plugged in and the power switch is on.
9
In the Avid NEXIS | E2 and the System Director Appliance, the PCMs operate in a redundant configuration. For
maximum protection from power loss, both PCMs must be plugged in to sep arate electrical ci rcuits and turne d on.
With both PCMs plugged in and turned on, the system balances its power needs between them. If one PCM fails,
the system can continue operating.
In the Avid NEXIS | E4, the PCMs operate in a dual-redundant configuration. For maximum protection from
power loss, each pair of PCMs must be plugged in to separate electrical circuits (for example, two on circuit A and
two on circuit B), and all must be turned on. With all four PCMs plugged in and turned on, the system balances its
power needs among them.
The Avid NEXIS | E4 can run with any two of the four PCMs working.
