Introduction
Enterprise Manager allows you to monitor, manage, and analyze Storage Centers from a
centralized management console.
Enterprise Manager consists of the following components:
•
Data Collector: Data Collector is a service that gathers reporting data and alerts from
all Storage Centers. There are two types of Data Collectors: Primary and Remote. All
installations must include one primary Data Collector. Installing a remote Data Collector
is optional. Each Data Collector service (primary or remote) is managed using a Data
Collector Manager.
•
Database: Data Collector stores data in a database or flat file. The database can run
on the same or a different platform from Data Collector. See Installation Requirements
on page 3 for a list of supported databases.
•
Enterprise Manager Clients: An Enterprise Manager Client connects to the Data
Collector Service to provide a centralized management console for one or more Storage
Centers. Additional clients can be connected to the same Data Collector Service to
provide management from more than one location.
•
Server Agents: By installing a Server Agent for Microsoft Windows on each Windows
server using a Storage Center, Data Collector can gather local volume information from
a Windows server. Using this information, Enterprise Manager can free volume storage
space from expired Replays that would otherwise remain locked by Windows. Each
Server Agent is managed by a Server Agent Manager.
This guide describes how to install and configure Enterprise Manager components. It also
describes how to use Data Collector Manager and Server Agent Manager. For information
on using Enterprise Manager clients, refer to the Storage Center Enterprise Manager User
Guide.

Introduction
Enterprise Manager Data Collector gathers data and alerts from the connected Storage
Centers and stores the data in a database or flat file. Enterprise Manager clients, in turn,
connect to the Data Collector to send and receive information to and from managed
Storage Centers.
Primary and Remote Data Collectors
All Enterprise Manager installations require a primary Data Collector to store and manage
Storage Center data. In addition to the primary Data Collector, you can optionally install a
remote Data Collector.
A remote Data Collector is connected to the primary Data Collector and can be used to
activate a disaster recovery site if the primary Data Collector becomes unavailable. To
install a remote Data Collector, first install and configure the primary Data Collector using
the instructions in this section. After the primary Data Collector is installed, configured, and
running, you can then install a remote Data Collector that connects to the primary Data
Collector. See Installing and Configuring a Remote Data Collector on page 23 for details on
installing a remote Data Collector.
Primary Data Collector Database Options
Before installing the primary Data Collector, determine the database to be used by Data
Collector to store data. Data can be stored using any of the following:
Database
Installation Instructions
Flat file
No database installation required.
MySQL 4.1 or 5.0 or 5.1
Microsoft SQL Server 2005
(or Microsoft SQL Server 2005 Express)
Microsoft SQL Server 2008
(or Microsoft SQL Server 2008 Express)
Complete installation before installing Data Collector.
Note The database option for storing data can be changed after installation. For
information on changing the Data Collector database after installation, see To
change Data Collector data source on page 37 for details.
Installation Procedure
Installing and configuring the primary Data Collector includes these steps:
1 If necessary, install database software.
If you already have database software installed or if you want to use a flat file for
storing data, skip this step. Otherwise, install the database software you want to use
for creating the Data Collector database.
2 Install the primary Data Collector.

was installed prior to the Data Collector installation. To correct the problem, update the
system PATH environment variable to point to the new version of Java.
To update the PATH environment variable:
1 Go to My Computer > Properties > Advanced > Environmental Variables >
System Variables > Path.

Introduction
Data Collector provides two levels of user security:
•
Open
Open security mode is the default mode. When running in open security mode, all
Enterprise Manager users have access to all Enterprise Manager functions. New users
can be created by an Enterprise Manager client when the client connects to the Data
Collector.
•
Enhanced
When running in enhanced security mode, the Data Collector controls user access to
Enterprise Manager functions and associated Storage Centers based on the group role
to which a user is assigned: a Viewer, Creator, or Administrator group. New users, as
well as the associated Storage Centers can be created and managed only by the Data
Collector Manager.
Note Before enabling enhanced security for the Data Collector, make sure there is at least
one user defined for the Data Collector. When running the Data Collector in the
default open security, you can define a Data Collector user by installing and
configuring an Enterprise Manager client and then connecting to the Data Collector.
See Installing and Configuring Enterprise Manager Clients on page 63.

102
Enterprise Manager 5.5 Installation and Setup Guide
R
RAID 0
Data is striped across the available disks providing improved performance. RAID 0 does
not provide any data redundancy.
RAID 5
Maintains a logical copy of the data using a mathematically derived rotating parity stripe.
The parity stripe is derived from the data stripes. This method has less overhead for the
redundant information than RAID 10; however, write performance is slower than RAID 10
due to the calculation of the parity stripe for every write. Read performance is similar to
RAID 10.
RAID 6
Has striped data with dual distributed parity and provides fault tolerance from two drive
failures. The array can continue to operate with up to two failed drives. This makes larger
RAID groups more practical, especially for high availability systems. This becomes
increasingly important because large-capacity drives lengthen the time needed to recover
from the failure of a single drive. Single parity RAID levels are vulnerable to data loss until
the failed drive is rebuilt: the larger the drive, the longer the rebuild will take. Dual parity
gives time to rebuild the array without the data being at risk if a (single) additional drive fails
before the rebuild is complete.
RAID 10
Data is striped across available disk drives and mirrored, providing data availability and
improved performance. Maintains a minimum of one full copy of all data on the volume.
RAID 10 provides optimum Read / Write performance, increased probability of withstanding
multiple failures, and the quickest restoration of data.
redundancy
Fault tolerance such that if some disks fail, all or part of the data stored by the array is not
lost. The cost of providing this feature is most typically increased disk space; RAID 10
requires a duplication of the entire data set. RAID 5-5 and 5-9 contain an error-correcting
algorithm stored on the array.
Remote Instant Replay
Point-in-time copy of a volume over a distance to a remote site. The sites can be activeactive, with bidirectional remote copies that can either have matched or split intervals.
Replay
Fully usable copy of data that contains an image of the data as it appeared at the point in
time at which the copy was initiated.
Replay space
Amount of space that is not actively being used by a volume and is contained in its replays.
This number does not include RAID overhead.
103
Replay profile
Collection of Replay rules that can be used for creating a Replay.
replicating system
Storage Center system being Replicated.
replication
Copying data to a remote location, online and in real time, via the internet or a corporateleased line connection.
restore points
Information stored by the Data Collector about the current state of Replications between
Storage Centers, including what volumes are being replicated, to where, what QoS node
Replications are using, and Source volume properties
S
SCSI (Small Computer Systems Interface)
Collection of ANSI standards which define I/O buses primarily intended for connecting
storage devices to servers.
server
Name representing the actual WWNs installed on the server.
Space Recovery
Utility that recovers space that Windows reports as being used but is actually empty,
available space that can be used by Storage Center.
spare disk
Disk reserved to replace a disk of same or smaller size in the event a disk in RAID 5 logical
unit fails. The controller rewrites the data from the failed disk to the replacement disk on the
fly.
starting base price
In Chargeback: The actual amount of storage that the base price covers before the
Department is charged for storage.
storage usage
Amount of space consumed by volumes on the disk (including Replays and RAID
overhead).
synchronous replication
Each write to the local site is written to the remote site before the application receives an I/
O complete message. The local volume and remote volume are fully synchronized at all
times. This redundancy ensures a near-zero loss of data and very quick recovery times
from failures at the local site.
