Introduction

The SRM NAS Agent gathers statistics on the network interfaces, system infrastructure, disk and file system assets (CIFS and NFS shares) of the NAS File Server (both NetApp and EMC Celerra are supported).

Data collected by the SRM NAS Agent is summarized by many types of reports that may be further customized with user-selected filters and charts in the Report Manager.

For the SRM NAS Agent, the agent software is installed in a proxy client. For more information on installing the proxy client, see Deployment - SRM NAS Agent. Once the installation is complete, the agent and the NAS file server information must be configured from the client level in the CommCell Console. For step-by-step instructions see, Add NAS Filer.

Supported Job Types for Data Collection

This agent supports two job types for data collection:

Discovery
Discovery and Analysis

Discovery Job

This job collects basic information about about network interfaces, system infrastructure, disks, file system and share details, CIFS and NFS performance statistics, quotas, NetApp qtrees and snapshots, EMC quota trees, quota configurations and checkpoints for the file server. Data collections using the Discovery level job require minimal processing on the proxy Agent computer and may be run throughout the day. If you select a Discovery level Data Collection Job, you will not receive meaningful data in certain of the more extensive reports.

Discovery and Analysis Job

This job collects detailed file-level statistics including information about file sizes, types, owners, extensions and create access and modification times. Data collections using the Analysis level job should be run during off-peak hours because they require processing that is CPU- and disk-intensive on the proxy Agent computer.

See Reports - SRM NAS Agent for more information about which reports require Analysis level data collection.

Tree Level in SRM NAS Agent

When the SRM NAS Agent is installed, the following levels are automatically created in the CommCell Browser.


hct:	Client
NAS:	Agent
default:	Subclients
Network Shares:	This level displays Network Shares information for the SRM NAS Agent's client computer. Logical Storage Volumes associated with the client computer are populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.
Data Movers:	This level displays Data Movers information for Celerra File Servers. Data Movers are populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.
File Systems:	This level displays File Systems information for Celerra File Servers. File Systems are populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.
Storage Pools:	This level displays Storage Pools information for Celerra File Servers. Storage Pools are populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.
Storage Systems:	This level displays Storage Systems information for Celerra File Servers. Storage Systems populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.
Meta-Volumes:	This level displays Meta-Volumes information for Celerra File Servers. Meta-Volumes are populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.
Logical Volumes:	This level displays Logical Volumes information for NetApp File Servers. Logical Volumes are populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.
vFilers:	This level displays vFilers information for NetApp File Server. vFilers are populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.
Aggregate Volumes:	This level displays Aggregate Volumes information for NetApp File Server. Aggregate Volumes are populated under this level after completion of the first Data Collection operation. For more information, see SRM NAS Agent Summaries.

Configuration Consideration

Consider the following configuration requirements prior to using the SRM NAS Agent:

The SRM NAS Agent functions as a proxy Agent and must be installed on a separate computer running one of the proxy Agent operating systems listed in System Requirements - SRM NAS Agent.
The SRM NAS Agent, a proxy agent, cannot communicate with the NAS File Server across a firewall, so the agent and the NAS device must be on the same side of the firewall.
In order to successfully start a migration archiving job, the NAS Filer name used in the SRM NAS Agent and in the subclient content path in the File Archiver Agent should exactly be the same (case-insensitive) or resolve to the same IP address.
Make sure that the subclient content path in the File Archiver Agent is not excluded from data collection.

License Requirement

To perform a data collection operation using this Agent, you need a SRM NAS Agent license, available in the SRM server. The license is consumed when this component is configured on the client computer. See License Administration for more details on license requirements.
