Overview
• Data Supervisor
• Data Event Monitor
• Data Integrator
• Dell OpenManage™ data management environments
Dell OpenManage™ data management software runs on a Microsoft Windows NT�
host that will be a Dell OpenManage™ data management station. The standard Dell OpenManage™
data management software consists of
- Dell OpenManage™ Data Supervisor
- Dell OpenManage™ Data Event Monitor
- Dell OpenManage™ Data Integrator
 |
NOTE:
Within in this guide we use the following terms: |
- Data Supervisor for Dell OpenManage™ Data Supervisor
- Data Event Monitor for Dell OpenManage™ Data Event Monitor
- Data Integrator for Dell OpenManage™ Data Integrator
- Data Agent for Dell OpenManage™ Data Agent for NT
- Data Administrator for Dell OpenManage™ Data Administrator
- Dell NNM SE for Dell Network Node Manager Special Edition for H P OpenView
- Management station for the host running Dell OpenManage™ data management software
- Managed array or array for a Dell PowerVault™ 650F or 651F storage system that is managed
by Dell OpenManage™ data management software
- Array server or server for a host that is connected to managed arrays and is running Data Agent
Data Supervisor provides a graphical user interface that lets you configure and manage arrays from
a physical viewpoint. Using Data Supervisor, you can group an array's physical disks into logical
units (LUNs) and monitor the status of the physical disks and other customer-replaceable units (CRUs)
that make up an array. Data Supervisor provides these features:
- Remote configuration of an array
- Monitoring of the overall operation of an array
- Remote management of an array
- Electronic distribution of Licensed Internal Code (LIC) to an array
You can have one session of Data Supervisor running on the management station, and with that session
you can configure and manage one array on one server. The array can be connected to the management
station or to an array server that is accessible to the management station over a network. Since Data
Supervisor communicates with the array using Data Agent, the server with the array must run Data Agent.
Data Event Monitor logs the status of managed arrays connected to servers on a network. You can
specify the managed arrays for which it logs status and the range of event messages to log.
When Data Event Monitor logs a status message, you can have it automatically start any application
that can be invoked from the MS-DOS command line. Such an application might send an error message to
the Windows NT event log or an electronic mail message or fax to the administrator of the arrays.
Data Event Monitor is required for managing arrays using Dell NNM SE.
Data Integrator incorporates arrays into Dell NNM SE. It provides the following for Dell NNM SE:
- Discovery of the arrays
- Launch of Data Supervisor or Data Administrator from Dell NNM SE
- Notification of changes in array status
Data Integrator is required for managing arrays using Dell NNM SE.
Discovery of arrays and launch of Data Supervisor
Dell NNM SE discovers devices on a network and represents them as icons on its segment map. This
map provides an overview of the network from which you display submaps that detail the devices on
the network, such as arrays.
You display a submap for an array server by double-clicking the server's icon. The submap contains
icons for the managed arrays connected to the server. If a server is connected to two storage
processors (SPs) in a managed array, a managed array icon appears for each SP. You can start a Data
Supervisor session for a managed array by double-clicking its icon in the submap. A sample of the
segment map and its submap is shown below.
Figure 1-1. Sample Dell NNM SE maps
Data Integrator consists of two parts: one part that runs on the management station and is a piece
of the standard Dell OpenManage™ data management software; and one part that runs on each host
connected to the arrays and is a piece of the Dell Managed Node software. The piece that runs on the
management station adds the Dell NNM SE extensions to Dell NNM SE so it can find arrays on the servers
that it discovers. With the Dell NNM SE extensions, Dell NNM SE can
- Examine each discovered host to determine if it has the other part of Data Integrator, which consist
of the Dell SNMP extensions for the managed arrays. These SNMP extensions identify which hosts are
servers for managed arrays.
- Check the servers that have the Dell SNMP extensions for a list of arrays that Dell NNM SE should
manage.
- Create a managed array icon for each managed array on the list.
Notification of status changes
Dell NNM SE event handlers capture changes in the status of the managed array. The Dell NNM SE events
are messages that are reported to, but not requested by, Dell NNM SE. Arrays send events to Dell NNM SE
through SNMP traps.
Data Integrator uses Data Event Monitor to generate the events for managed arrays. Data Event Monitor
lets you monitor the status of any managed arrays that are accessible on the network. Data Event Monitor
queries the Data Agent on the servers for changes in their managed arrays, and sends Dell NNM SE generic
SNMP traps that indicate status changes. Dell NNM SE in turns logs these traps. You can use the Dell NNM
SE Alarm log to view trap messages.
A management station can also be an array server. If a management station is running Dell NNM SE,
it is called a Dell NNM SE management station.
Environment without a Dell NNM SE management station
The figure below shows a Dell OpenManage™ data management environment in which the management
station is not running Dell NNM SE and is not an array server. From this management station, you can
manage all the arrays connected to servers on the network using Data Supervisor, Data Administrator,
or Data CLI.
Figure 1-2. Environment with a non-Dell NNM SE management station that is not an array server
The figure below shows a Dell OpenManage™ data management environment in which the management
station is not running Dell NNM SE and is an array server, From this management station, you can
manage all the arrays connected to servers on the network using Data Supervisor, Data Administrator,
or Data CLI.
Figure 1-3. Environment with an non-Dell NNM SE management station that is also an array server
The Dell OpenManage™ data management software runs on the management station and communicates
with the Data Agent running on each server. Data Agent on a server communicates with the Licensed
Internal Code (LIC) running on an array's storage processors (SPs). The Dell OpenManage™ data
management software and Data Agent communicate with each other over a TCP/IP network. Data Agent and
the Licensed Internal Code communicate with each other using a SCSI protocol over a Fibre Channel
arbitrated loop (FC-AL). The figure below shows how these components interact.

station
Environment with a Dell NNM SE management station
To monitor managed arrays and start Data Supervisor or Data Administrator from a Dell NNM SE management
station, you must have the following software:
On each array server
- Windows NT SNMP Service, which provides the Windows NT SNMP extendable agent
- Dell SNMP extensions, which is the part of Data Integrator for an array server
On the Dell NNM SE management station
- Dell NNM SE
- Dell NNM SE extensions, which are the part of Data Integrator for the management station
- Data Event Monitor
The figure below shows a Dell OpenManage™ data management environment in which the management
station is running Dell NNM SE and is not an array server. From this Dell NNM SE management station,
you can use Dell NNM SE to monitor all the arrays connected to servers on the network.
When you want to configure a managed array or view detailed status information about a managed
array's hardware, you can start Data Supervisor or Data Administrator from Dell NNM SE.

NOTE:
The part of Data Integrator on the Dell NNM SE management
station is the Dell NNM SE extensions; the part on a Window NT server is the Dell SNMP extensions. |
The Dell OpenManage™ data management software running on the Dell NNM SE management station
communicates with the Data Agent running on each array server in the same way that is does on a
non-Dell NNM SE management station. Data Agent on an array server communicates with the Licensed
Internal Code (LIC) running on an array's storage processors (SPs). The Dell OpenManage™ data
management software and Data Agent communicate with each other over a TCP/IP network. Data Agent
and the Licensed Internal Code communicate with each other using a SCSI protocol over a Fibre
Channel artibrated loop (FC-AL).
The Dell NNM SE extensions, which are the part of Data Integrator on the Dell NNM SE management
station, let the Dell NNM SE find arrays on array servers that it discovers on the network.
Data Event Monitor on the Dell NNM SE management station communicates with Data Agent on each array
server about status changes in a server's managed arrays. It passes the array status information it
receives to Dell NNM SE. Data Event Monitor communicates with Data Agent on each array server using
the Windows NT SNMP extendable agent with the Dell SNMP extensions over the TCP/IP network. Data Event
Monitor also communicates with Dell NNM SE over the TCP/IP network. The figure below shows how these
components interact.
