Getting Started

This section provides an overview of Storage Center System Manager and identifies the steps to get started.

Overview

Storage Center System Manager provides a central management interface to create and manage Storage Center volumes, servers, disks, and users.

Use System Manager to:

• Provision volumes and map them to servers. • Display the status of hardware components. • Manage local backup and restore.

• Phone Home information to Dell Technical Support Services. • Set up users and access privileges.

In addition to the System Manager, Storage Center provides a rich set of separately licensed applications that support dynamic storage. To view currently licensed applications, select Licensed Features from the Help menu.

• Balance unbalanced ports: In the message dialog box, click Yes to rebalance local ports.

• Turn off the rebalance ports message:

a Select the Controllers node icon in the System Tree by right clicking on it. b From the shortcut menu, select Rebalance Local Ports.

c Uncheck the option to check for unbalanced local ports at startup.

IO Card Change Detected

If an IO card change is detected on system startup, Storage Center automatically launches the IO Card Change wizard.

See Also

Managing IO Card Changes on page 181

Unmanaged Hardware

If the System Manager finds unmanaged hardware, such as disks or server host bus adaptors (HBAs), it prompts you to manage them.

Note: The End User License Agreement is displayed the first time a new user

(16)

View the System Dashboard

The center pane of the System Explorer opens to the system dashboard with Storage

Summary and Storage History displayed.

If a Storage Center system has more than one disk folder, the System Manager displays a

Storage Summary and Storage History for each disk folder.

The upper pane shows the Storage Summary in a graph and in list form.

The lower pane shows Storage History in a chart that tracks disk use over time. • The Blue banner shows when the history was generated.

• The Blue line shows the amount of space used recently. • The Red line shows the amount of raw disk space available. • The Yellow line shows the Low Space Threshold.

Field Description

Blue banner Date and time when the summary was generated.

Status Current status of storage utilization. When the Free disk space available falls below the Low Space Threshold (10%), the Status value changes to Space Low.

Total disk space Amount of raw disk space available (gold in the bar graph). Used disk space Space used by volumes and replays (blue in the bar graph). Free disk space Space available for volumes and replays (gray in the bar graph). Unhealthy/Bad Space Space (if any) found on any unhealthy disks, or any bad space found

on disks that are healthy. This appears only if unhealthy or bad disk space has been found (black in the bar graph).

More Details Link to Online Storage view, which contains charts that detail storage use and trends.

Navigating the Interface

This section describes the main elements of the System Manager user interface.

Storage Management Menu

The Storage Management menu is located in the upper-left corner of the main pane. Click the Storage Management menu to see the menus and options for viewing and configuring Storage Center.

(18)

View Menu

The View menu provides multiple ways to configure a system or view system properties. Options are specific to each individual view. After a specific view is displayed, the tab for that view appears in the upper pane of the System Explorer window for the remainder of the current session.

Click View to open the View menu.

If more tabs are available than can be displayed, the window displays scroll arrows to the far right of the view tabs. Click the arrows to scroll through the open tabs.

Context Menu

Context menu commands that apply to commands currently being used appear near the top of the System Explorer window.

If there is not sufficient room to display all context menu commands at the top of the window, a down arrow is displayed. Click the arrow to display all commands shown in the shortcut menu.

Next Steps

This section identifies basic tasks that you may need to perform after your first log on to Storage Center System Manager. These tasks are configuration dependent and not all tasks are required at all sites.

Set Controller and System IP Address for IPv6

If you are using IPv6 addressing, you must set the Management IP address in the Controller Properties and in the System Properties. Make sure that you set the controller IP addresses first.

See Also

Set Controller IP Properties on page 142

Set the System Management IP Address on page 227

Manage Unmanaged Disks

It is usually assumed that disks attached to the Storage Center controller were identified and assigned during installation. If not, Storage Center recognizes unmanaged hardware and asks that you manage (assign) it. Storage Center groups disks into a disk folder to create a pool of storage from which volumes are created.

See Also

Manage Unassigned Disks on page 198

Change the Admin Password

The default administrator password is mmm. It is recommended that you change the default before Storage Center is put into production.

See Also

Change Local User Passwords on page 314

Create Servers

Creating a server means to identify it to a Storage Center using the Create Server wizard. You can also communicate with the server using iSCSI CHAP by adding remote CHAP initiators.

See Also

Managing Single Servers on page 110 Managing Server Clusters on page 115 Managing Virtual Servers on page 124 Add a Remote CHAP Initiator on page 174

Configure User Volume Defaults

Access to Storage Center is based on volumes and volume settings.

(21)

Next Steps

Create Volumes

Depending on the configuration at your site, you may need to create volumes to organize data and users.

See Also

Create a Volume on page 17

Create Multiple Volumes for a Server on page 22

Apply Replay Profiles

A Replay Profile is a collection of rules describing when to take periodic Replays for one or more volumes and the time at which Replays are deleted (expired). Replays create space-efficient point-in-time copies (PITC) to provide immediate recovery from data loss. System Manager provides standard replay profiles, and you also can create replay profiles that fit specific needs. In either case, you must apply a replay profile to each volume before it is included in any replay activity.

See Also

Replay Profiles on page 59

Review Storage Profiles

Storage Profiles determine how to move data most effectively within Storage Center. By default, a storage profile is applied to each volume.

When licensed, Storage Center uses Data Progression to write and move data so that the most active blocks of data remain on high-performance solid state drives (SSDs) or Fibre Channel drives, while less active blocks automatically move to lower-cost, high-capacity SAS drives. This is the most effective storage profile for typical Storage Center use. If you are using Solid State Drives (SSDs) or are working with Dell Technical Support Services to manage data movement, you may need to create or apply a different storage profile.
