Overview of LUN and LUN Group management
Dell OpenManage™ Data Organizer provides a graphical user interface that lets you manage
Dell PowerVault™ 650F and 651F storage systems from a logical viewpoint, rather than from
the physical component viewpoint that Dell OpenManage™ Data Supervisor or Dell OpenManage™ Data
Administrator provides. Using Dell OpenManage™ Data Organizer, you can monitor the status and
performance of logical units (LUNs) and groups of LUNs on the storage systems. The LUNs within
a group can be on different storage systems on different hosts. For example, if you have
different storage systems each with LUNs that store parts of the same large database, you can
group these LUNs together, and monitor the status and performance of the entire database group,
in addition to monitoring the status and performance of the LUNs that make up the group.

NOTE:
Throughout this guide we use the following terms:
- Data Organizer for Dell OpenManage™ Data Organizer
- Data Administrator for Dell OpenManage™ Data Administrator
- Data Agent for Dell OpenManage™ Data Agent for NT
- Data Analyzer for Dell Open Data Analyzer
- Managed array for a storage system with LUNs that are managed by Data Organizer
- Array server or server for a host with a managed array
|
Data Organizer runs on a Microsoft Windows NT™ host, called a management station.
It can manage LUNs on arrays connected to servers that are accessible to the management
station over a network, as well as LUNs on arrays connected to the management station.
Since Data Organizer communicates with the LUNs that it manages using Data Agent for NT,
the servers with managed arrays must run Data Agent for NT.
If Data Administrator or Data Analyzer is installed on the management station,
you can start a Data Administrator or Data Analyzer session from a Data
Organizer session.
The sample Data Organizer environment that follows shows a Windows NT host that is a
management station and not an array server. You can use this host to manage
the LUNs and LUN Groups on arrays on servers running Data Agent (namely, the Windows
NT server that is the management station and the other Windows NT servers).
Figure 1-1. Sample Data Organizer environment with a management station that is not a server
The sample Data Organizer environment that follows shows a Windows NT host as both
a management station and an array server. You can use this host to manage LUNs and
LUN Groups on its own arrays and to manage LUNs and LUN Groups on arrays on other
servers running Data Agent (namely, the Windows NT server that is the management
station and the other Windows NT servers).
Figure 1-2. Data Organizer environment with a management station that is also server
Data Organizer communicates with a Data Agent on the same or other servers on the network.
The management station and the remote Data Agents for NT communicate with each other over
a TCP/IP network. Data Agent uses a SCSI protocol over a Fibre Channel arbitrated loop
(FC-AL) to communicate with the LIC running in an array's storage processors (SPs).

To configure LUN Groups using Data Organizer, you perform the following tasks:
- Install and start Data Organizer on the management station
(Installing and starting Data Organizer).
- Create LUN Groups
(Creating, renaming, or reconfiguring LUN Groups).
To manage LUNs and LUN Groups using Data Organizer, you perform the following tasks:
- Monitor the status and utilization of LUNs and LUN Groups
(Monitoring LUNs and LUN Groups).
- Display performance and status information for LUNs, LUN Groups,
and the disk modules that comprise the LUNs
(Displaying status, statistics, and performance information).
- Reconfigure LUN Groups as needed
(Creating, renaming, or reconfiguring LUN Groups).
