About Harmonic MediaGrid

Harmonic MediaGrid is a powerful disk storage server system specifically designed with the needs of large file storage and access in mind. Harmonic MediaGrid boasts unique capabilities to meet the most demanding capacity, performance and data availability requirements. The software RAID implementation is tightly integrated into the File System delivering high performance and fast RAID rebuilds.

Harmonic MediaGrid is configured in a single VLAN and single subnet architecture. This configuration is designed for easier configuration, and provides faster failover response time in the event of a Harmonic MediaGrid switch failure, ensuring data protection and reliable system operation. Depending on the number of switches and ContentServers, failover time is reduced to a matter of seconds.

Harmonic MediaGrid Components

A Harmonic MediaGrid system is comprised of the following components:

 Network Switches

 ContentDirector

 ContentServer

 ContentStore

 ContentBridge

 SystemManager

 Harmonic MediaGrid File System Driver Software

Network Switches

The network switches interconnect the many components both within a rack and to the client network. The Harmonic MediaGrid 4000 Series and 3000 Series require multi-port network switches with both 1 GbE and 10 GbE modules.

Chapter 1 System Overview and Requirements

Harmonic provides one network switch, which can only be used for systems with the ContentServer 3000. However, Harmonic MediaGrid supports several switches. For information on switches that are currently Harmonic MediaGrid-qualified, contact your Harmonic representative.

Switches may be qualified for Harmonic MediaGrid based on specifications or testing. If you wish to have a new switch qualified, please make an effort to obtain data on latency, throughput, nonblocking fabric, and port buffering from the manufacturer and include it with a qualification request to your Harmonic representative.

IMPORTANT: The ContentServer 3000/4000 series cannot be connected directly to CX4 ports.

If you are supplying a switch for a Harmonic MediaGrid system with the ContentServer 3000 or 4000, the following switch functionality is required:

 Full wire-speed, non-blocking architecture  Latency of less than 5uS  Port buffers of 10 MB per port

ContentDirector

Harmonic MediaGrid Components

ContentDirectors act as the overall file system controllers, managing the distribution of data throughout the system and providing data maps to clients for writing and retrieval of media from the system. In addition, the ContentDirector performs storage management and file housekeeping functions.

Two models of ContentDirectors are available. Refer to ContentDirector 1000F and High Performance

ContentDirector 2000C for additional information about this component.

ContentServer

ContentServers store data on disk drives and deliver files upon request from desktop clients or from legacy clients through a ContentBridge. ContentServers with RAID support have dual activeactive controllers and redundant data paths to protect against any storage node failures.

 ContentServer 3000 (16-drive, 3RU server): The ContentServer 3000 is available with ether

1 GbE or 10 GbE Ethernet ports for connections to the network switch. Refer to ContentServer

3000 for additional information about this server.

 ContentServer 4000 (24-drive, 4RU server): The ContentServer 4000 is equipped with 10

GbE Ethernet ports. Refer to ContentServer 4000 for additional information about this server.

ContentStore

ContentStores can be connected to ContentServers to provide additional storage bandwidth and capacity for holding user data.

 ContentStore 3160 (16-drive, 3RU server): In single stack, up to 5 ContentStore 3160

nodes can connect to the ContentServer 3000. Refer to ContentStore 3160 for additional information about this server.

 ContentStore 4240 (24-drive, 4RU server): In a single stack, up to 4 ContentStore 4240

nodes can connect to the ContentServer 4000. Refer to ContentStore 4240 for additional information.

Chapter 1 System Overview and Requirements

 ContentStore 5840 (84-drive 5RU server): At this time, a single ContentStore 5840 can

connect to the ContentServer 3000 or 4000. Refer to ContentStore 5840 and 5840A for additional information about this server.

IMPORTANT: Harmonic MediaGrid 3000 series and 4000 series units cannot be combined in a single stack.

ContentBridge

The ContentBridge is an optional server that provides access to Harmonic MediaGrid for client platforms that do not have the File System Driver (FSD) installed or do not use the Harmonic MediaGrid API. The ContentBridge also supports active files transfers. This server provides a translation function for the following protocols:

 CIFS (Common Internet File System)  FTP (File Transfer Protocol)  NFS (Network File System)

Refer to ContentBridge 2010F for additional information about this component. The 2010F is available with copper CX4 or multi-mode fiber connectors.

Harmonic MediaGrid Components

SystemManager

The SystemManager platform is comprised of both hardware and software components that communicate with the Harmonic MediaGrid network over Ethernet, providing software update capability, network management, configuration, security and fault monitoring services.

Harmonic MediaGrid features that are enabled, modified, or part of the SystemManager application are described in the SystemManager documentation. See the Harmonic SystemManager User Guide for more information.

Harmonic MediaGrid ContentManager

A separate ContentManager application is also available from Harmonic. ContentManager is used for setting, reviewing and changing attributes on associated files, directories, and user permissions of Harmonic MediaGrid. Refer to the ContentManager User’s Guide for more information.

Harmonic MediaGrid File System Driver Software

Harmonic MediaGrid file system driver software, installed on customer supplied desktops, communicates with the system to store and retrieve files. See the Harmonic MediaGrid Release Notes for your particular client platform for the latest supported client operating systems.

About Jumbo Frames Support

Jumbo frames are a feature that allows for larger transmission sizes of Ethernet frames over a network. Harmonic MediaGrid supports jumbo frames; however, every device on your network between Harmonic MediaGrid and the client (including the client itself) must also support jumbo frames, with a common packet size, to take advantage of this feature. Network performance is severely impaired otherwise.

Chapter 1 System Overview and Requirements

Jumbo frames may improve transfer performance between Harmonic MediaGrid and other devices on the network in some cases. However, an improvement will not always be obtained, depending on the devices’ ability to process data relative to the maximum network transfer speed available.

The Network Switches are enabled by default. Refer to Configuring a ContentServer to enable jumbo frames on the remaining Harmonic MediaGrid devices.

Harmonic strongly recommends that the Harmonic MediaGrid be initially set up and tested with all other parts of the system infrastructure with jumbo frames disabled, to ensure correct functionality, before enabling jumbo frames.

About Naming Files and System Elements

The following table provides important notes about the naming of files, devices, hosts and file systems on a Harmonic network.

Element Notes

Harmonic MediaGrid Components

Filename Clip Name

Naming conventions follow Windows32™ rules. In general, names can be quite long. Standard alphanumerics are allowed: a-z, A-Z, 0-9. Most characters, including spaces, are valid except: / \ : * ? < > | and the double quote character (“).

Device Name Host Name

Maximum name length is fifteen characters. Standard alphanumerics are allowed: a-z, A-Z, 0-9 also _ (underscore) and -(dash). 9 special characters are allowed for Device or Host names: ! ^ ( ) { } - _ ~ No spaces are allowed.

File system Name Maximum name length is eight characters.

Standard alphanumerics are allowed: a-z, A-Z, 0-9 also _ (underscore) and -(dash). 9 special characters are allowed: ! ^ ( ) { } - _~ No spaces are allowed.

Keep in mind the following additional points:

 For a Harmonic system with an Omnibus automation system, clip names are usually

generated on the Omnibus side. To create clips for use on an Omnibus system, follow these guidelines:

 Avoid creating long Harmonic clip names that only differ in the last few characters as long

Harmonic clip names are truncated to 25 characters when Omnibus clip names are generated.

Avoid creating file (or clip) names that differ only in uppercase/lowercase iteration. Harmonic MediaGrid correctly preserves the case of the file names and treats the files as separate. However, some operating systems (Windows most notably) and some applications do not properly handle file names that are identical except for differences in case.

Chapter 1 System Overview and Requirements

About Clusters, Volumes and Groups

When setting up a Harmonic MediaGrid 4000 or 3000 system, generally, there will be one cluster, one volume, and one group, all of which are generated automatically by the configuration assistant.

Keep in mind the meaning of these concepts:

 A Cluster includes a Volume and its associated ContentDirectors, ContentServers and

ContentStores within a Harmonic MediaGrid.

 A Volum e includes the file system, one Group, and its associated ContentServers and

ContentStores in a Harmonic MediaGrid.

 A Group is a collection of one or more ContentServers and ContentStores in a Harmonic

MediaGrid.

About a Harmonic MediaGrid Stretch Cluster

Harmonic MediaGrid supports using replication on systems with the ContentServer 3000 Series. This feature provides an additional level of data protection by allowing you to set up a Harmonic MediaGrid system across two different sites and replicate data across sites. This configuration is known as a “stretch cluster.” In the event of a site failure, replication ensures that the data will be available at the second site.

About Clusters, Volumes and Groups

Because of the added redundancy in a stretch cluster, note that storage capacity will be reduced. Make sure to work with your Harmonic representative to size your system appropriately. Also note that although this configuration results in faster read operations, write operations are slowed.

System Requirements

 To configure a stretch cluster, you must have a minimum of six nodes in the cluster. This

means each of the two sites in the cluster must include at least one ContentServer with two ContentStores connected to it.

 The two sites in a stretch cluster must be no more than 20 kilometers apart.  Each ContentDirector in your system must have a fiber optic network card installed. For

assistance, contact your Harmonic representative.

 Systems must be configured with two groups, one for each site.  Each group in the cluster must have the same amount of storage with exactly the same

combination of ContentServers and ContentStores.

 The replication factor for the cluster must be set to 2.

Sample Diagram

Figure 1–1 shows a sample stretch cluster.

NOTE: The dark blue lines and gray lines represent different connections on the same Public VLAN.

NOTE: For cross-site connections, you must use fiber optic cable attached to a fiber optic card installed

on the ContentDirector.

Supported RAID Configurations

Figure 1–1: Harmonic MediaGrid Stretch Cluster

Supported RAID Configurations

Understand the difference between “capacity optimized” and “performance optimized” RAID configurations, and which configurations are supported in each ContentServer and ContentStore model.

Chapter 1 System Overview and Requirements

About the Capacity Optimized RAID Configuration

In the capacity optimized RAID configuration, the disk drives are configured in a Dual Parity (DP) RAID array, ensuring that the system can continue to function despite the failure of any two disk drives. This configuration optimizes storage capacity at the cost of bandwidth. A capacity optimized RAID set typically uses a 6+2 configuration.

NOTE: In the ContentStore 5840, capacity optimized RAID sets use a 5+2 configuration.

About the Performance Optimized RAID Configuration

In a system configured for performance optimized RAID, each RAID set has a single redundant disk drive, and each enclosure has N total number of hot spares. This configuration optimizes bandwidth at the cost of storage capacity.

IMPORTANT: If using SystemManager to create RAID sets, make sure that all ContentServers and ContentStores in a stack are configured with the same RAID geometry.

NOTE: No other disk drive configurations are supported.

About Drive Replacement

For systems with version 3.2.2 and later, you may use different capacity Harmonic-supplied drives in the same ContentServer or ContentStore RAID set.

Note the following when replacing a ContentServer or ContentStore drive with a different capacity drive than the others in the same RAID set:

 Any drive you add to an existing RAID set must be at least as large as the smallest

existing drive in that RAID set.

 Adding a drive that is larger than the smallest drive in the RAID set will cause it to be

treated as if it were the lesser capacity drive. In other words, the RAID set capacity will not increase by replacing smaller drives with larger drives.

Network Configuration

For drive replacement instructions, refer to the Harmonic MediaGrid Component Replacement Guides.

Network Configuration

This section lists site-specific information required to join a Harmonic MediaGrid system to a Windows domain and to incorporate Harmonic MediaGrid into an existing network. This information is provided for both customers and the installers. This information must be available prior to Harmonic MediaGrid installation.

Public VLAN

Before installing your Harmonic MediaGrid system, you must allocate an IP address range for the Harmonic MediaGrid Public VLAN. The Public VLAN is an IP subnet, which will be visible by all parts of the network that access the Harmonic MediaGrid. Make sure the Public VLAN is dedicated to Harmonic MediaGrid components, and accessible by clients that will access the Harmonic MediaGrid. See Figure 1–2 for an example.

IMPORTANT: You must allocate a dedicated IP address range for your Harmonic MediaGrid Public VLAN, advertise it to all routers on your network, and know this range before configuring your Harmonic MediaGrid system or switches.

IMPORTANT: The Public VLAN should include Harmonic MediaGrid devices ONLY. Adding non-Harmonic MediaGrid devices to the Public VLAN may cause unpredictable problems with the Harmonic MediaGrid system.

Private VLANs

Before installing your Harmonic MediaGrid system, you must also allocate IP address ranges for two Private VLANs. The Private VLANs are private IP subnets that create redundant paths between the ContentDirectors, allowing them to communicate information and keeping them synchronized. Make sure each Private VLAN is accessible by both ContentDirectors, and isolated from the other Private VLAN. See Figure 1–2 for an example.

Network Configuration

Figure 1–2: Network Configuration Diagram

NOTE: The connections shown in Figure 1–2 do not necessarily represent the number of IP addresses needed per device.

Chapter 1 System Overview and Requirements

Network Diagram with 10 GbE Network

The network topology diagram in Figure 1–3 shows a basic network configuration using the ContentServer 4000, or the ContentServer 3000 with 10 GbE NIC cards.

In Figure 1–3, note the following:

 Private VLAN 1 is a dedicated VLAN defined on the 1 GbE switch shown on the left. Private

VLAN 2 is a dedicated VLAN defined on the 1 GbE switch shown on the right. The ContentDirectors must communicate on both private VLANs.

 To allow failover, the Public VLAN indicated with the blue cables must also be connected to

the switch or module from the Public VLAN indicated with the gray cables. The separate colors indicate failover configuration only; in reality these are the same VLAN.

 The BMC connection indicated by turquoise cables is used for a troubleshooting utility called

the Baseboard Management Console (BMC). This requires a 1 GbE connection from each controller on a ContentServer to the 1 GbE switch. The BMC cables should be connected to the Public VLAN.

 ContentStores are connected to a ContentServer via SAS cables.

Required Information for a Windows Domain Controller

A domain controller server, which manages access to resources within a Windows domain, is required at the installation site. Harmonic MediaGrid must be “joined” to the site’s Windows domain for user authentication and security when clients attempt to access Harmonic MediaGrid file systems.

NOTE: Instructions on how to configure a Windows Domain Controller are not included in this guide. The domain controller should be set up before installing Harmonic MediaGrid.

The following information is required to join Harmonic MediaGrid to a Windows domain:

 The type of Windows domain controller (Windows Server 2012, Windows Server 2008).  The name of the Windows domain controller.  The IP address and the name of the Windows Active Directory controller machine.  A domain administrator’s user name and password for the Windows Active Directory

controller.

Required Information for a Windows Domain Controller

 The site’s Active Directory domain name. The Active Directory domain name must be a Fully

Qualified Domain Name (FQDN), which is a domain name containing three or four parts, (for example, “ahost.example.com”).

 The site’s Windows NT domain name. This may often be the first word of the Active Directory

domain name.

 The IP address of the DNS (Domain Name System) server that contains entries for the

Windows Active Directory controller machine.

Required Information for Network Configuration

Harmonic MediaGrid is a network storage system, running its own DHCP server for management of the subnets within the system. The ContentDirector that runs the DHCP server assigns IP addresses to the ContentServers. A range of IP addresses must be reserved for integrating Harmonic MediaGrid into the customer network.

NOTE: Instructions on how to design a network infrastructure are not included in this guide. The network should be set up before installing Harmonic MediaGrid.

The following information is required for network configuration of the Harmonic MediaGrid system. You will need this information when you run the configuration assistant to configure your system:

 The total number of each Harmonic MediaGrid device.

NOTE: The Harmonic MediaGrid configuration assistant asks for the maximum number of devices you wish to allow for in your system. If you select a number that is too low for future expansion, you may be forced to incur system down-time in order to reconfigure the system at a later time.

 Cluster names and device names  For the Harmonic MediaGrid 3000 Series only: Type of network (1GbE or 10 GbE)  MTU (maximum transmission unit) size per ContentBridge

Chapter 1 System Overview and Requirements
