The EMC R710 is a 2U rack mounted server designed to address the needs of mainstream enterprise, datacenter, and remote office customers as well as growing small businesses with 3 or more servers. The Intel Nehalem‐EP 2S (Efficient Processor), is the microprocessor designed specifically for servers and workstation applications. The processor features quad‐core processing to maximize performance and performance/watt for datacenter infrastructures and highly dense deployments. The Nehalem‐EP 2S processor also features Intel’s Core™ micro‐architecture and Intel 64 architecture for flexibility in 64‐bit and 32‐bit applications and operating systems.

All ADS nodes are tested, burned‐in and preloaded with the operating system. There are new Snap‐in rails that ship with the system making it easier for installation and replacement/repair.

The Avamar Data Store Generation 3 hardware nodes consist of 1TB and 2TB nodes, Utility nodes and a accelerator node. Each node comes preloaded with Red Hat Linux release 4 update 8. Capacity for the storage nodes are 1TB and 2TB licensed respectively. The utility node provides essential internal services for the server (for example, Administrator server, cronjob, Domain Name Server [DNS], External authentication, Network Time Protocol [NTP] and Web access). Because utility nodes are dedicated to running these essential services, they cannot be used to store backups. The accelerator node is a specialized node that utilizes NDMP in order to provide data protection for NAS filers (for example, EMC Celerra, Network Appliance) and Novell NetWare servers.

A single node server software installation combines all features and functions of Utility and Storage nodes in one unit. This server type must be installed in a customer provided location. The Avamar system can efficiently replicate data from one Avamar server to another on a scheduled basis. This ensures complete data recovery if the primary backup Avamar server is lost. Single node servers require a replication target.

Note: Generation 3 nodes have been qualified to run Avamar software versions 4.0 and 4.1.

All storage nodes in a grid must be of the same size (different H/W generations ok).

All nodes in a grid must run the same Avamar software version.

Hardware Rail KitHardware Rail Kit

• Snap‐to‐node, Snap‐to‐rack

• Support for circular and universal square hole racks

• Backwards compatible to Gen2 servers

• Forward and reverse direction stops

New rail kits have been designed to ease installation and repair. These snap‐in rails lessen the replacement time at a customers site. The rails are designed to support circular and universal square hole racks and are backwards compatible to 2nd generation servers. Also these rails have forward and reverse direction stops.

All Generation 3 nodes will ship from the factory with serial number and part number labels located on the top and bottom of the LCD panel for easier identification is a rack mount scenario.




Allied Telesyn SwitchAllied Telesyn Switch

• Ports 1‐4 to customer switch are trunked ports: Eliminates single point of failure

• Ports 1‐4 can also be assigned to optical ports

• Port 5‐23 to racked servers

• Port 24 remains a service access port as with previous Gen2 systems

• EMC field personnel will apply patch & config file for each install or repair

RJ45 switch service port

Optical Ports

The 9924T is an advanced Gigabit Ethernet switch. The 9924T provides fine service provisioning granularity and high availability. The switch supports 10/100/1000 x 24 ports and 4 optical ports which can be used instead of the first 4 Ethernet ports of the switch. The 9924T is enclosed in a 1RU standard rack mount chassis. Ports 1‐4 are BONDED trunked ports which eliminates single point of failure in the customers environment. Ports 5‐23 are for connections to the Avamar servers. Port 24 is reserved as the service port. Upon configuration of the Avamar grid, EMC service will apply patch and configuration files for proper operation.

Optional Storage/Expansion













If the customer determines that their system needs more storage space, expansion nodes can be added to a Avamar grid over time to expand storage. These expansion nodes must be installed at customer site and snap‐in rails will ship with the node(s). In order to put the expansion node into service as a utility or storage node, certain follow‐on configuration procedures must be performed. You must first configure the basic networking capabilities of the node. Then join the node to the grid and balance the nodes. Only 2 expansion nodes can be added at any given time. Consult EMC Avamar expansion node documentation for further assistance.

Avamar clients connect directly with Avamar nodes; client connections and data are load balanced across the storage nodes once the new expansion nodes are installed by EMC service personnel or authorized partners.




Generation 3 Rack AllocationGeneration 3 Rack Allocation

Click here to see enlarged table.

Systems are custom manufactured from 5 to 18 nodes but expansion nodes can be added in the field to expand a system with less than 18 nodes. Accelerator nodes are always shipped for field installation.

A multi‐node server consists of three kinds of nodes:

• Utility

Hosts basic control and communication services (for example, administrator server, cronjob, NTP and so forth).

• Storage

Stores the actual client backups.

• Spare

Can be reconfigured later as storage nodes.

The utility node is initially located in second from the bottom of a multi‐node configuration with the spare node and storage nodes stacked above it, in that order.

The spare node is the same hardware as the active storage nodes. Avamar Data Store configurations larger than six nodes can be built by adding expansion nodes. The Pre‐racked servers can be built with 5 nodes, all the way up to 18 nodes which is the maximum configuration

TroubleshootingTroubleshooting

HTTPS connection to IP address of Eth1• IPMI v2.0 compliant

• Gathers system logs, alerts, voltages, etc.

To ensure ADS is healthy, use dpnctl status command (Indicates if gsan, mcs, ems, and scheduler are up or down.

The system diagnostics program is run from the iDRAC6 Express System Services menu. The purpose of the diagnostics is to test your system's hardware without requiring additional equipment or risking data loss. To access the diagnostics software use a HTTPS connection to the IP address of Eth1or the dedicated DRAC Ethernet port. This program gathers system logs, alerts, voltages, etc.

There are many reasons why a server might be slow to respond. To investigate reasons for slow server response times, review the following log files:

• avqinstall primary log file, /usr/local/avamar/var/log/avqinstall.log

• avqinstall temporary log capture files, /tmp/avqinstall*

• gsan logs on each storage node, /data01/cur/{err,gsan}.log

• MC server log file, /usr/local/avamar/var/mc/server_log/mcserver.log.0

• EM server log file, /usr/local/avamar/var/em/server_log/emserver.log.0

• Maintenance cron job, /usr/local/avamar/var/cron/*.log

• Log files maintained by vendor RAID monitoring software

• System log files

• The output of dmesg, which displays the kernel's log buffer

To ensure that the Avamar Data Store node is healthy, use dpnctl status command. This indicates if gsan, mcs, ems and the scheduler are up or down. Must be logged in as root.
