1 IntroductionThe NetApp E-Series storage array is a high-performance storage system that meets demanding performanceand capacity requirements without sacrificing simplicity and efficiency. Designed to address wide-ranging solutionrequirements, its balanced performance is equally adept at supporting high performance file systems, bandwidth-intensive streaming applications, and transaction-intensive workloads. And its fully redundant I/O paths, advancedprotection features, and extensive diagnostic capabilities deliver the highest levels of availability, integrity, andsecurity.

This Lab Guide provides you the opportunity to work with the E-Series storage arrays and the storagemanagement software, and allows you to experiment with different configuration options. It introduces thefundamentals of SANtricity System Manager and its operations.

You will notice that this Lab gives you some guidelines to common operations, but does not give you complete,step-by-step instructions that detail every button click.

If you have questions about the steps or instructions in any lab, there are several places you can find information:

1. Help section (top right corner) of the SANtricity System Manager interface.2. Participant guide.3. Your lab proctor.4. SANtricity manuals.5. Firmware/NVSRAM information “Product Release Notes”.6. Interoperability/compatibility matrix available through company's website.

1.1 Lab ObjectivesThis lab walks you through different systems configuration options when implementing the an E-Series storagearray. The lab shows how easy it is to configure multiple disk protection schemes, allocate storage space, andmake on-line changes that outline high availability. This lab is designed to educate storage administrators aboutthe many configuration options they might face during implementation of the storage array in the field.

1.2 PrerequisitesYou should have a good understanding of the following technologies before you take this lab:

1. Understanding the fundamental differences between a NAS and SAN devices and associated services.2. Familiarity with the medium connectivity options (i.e., FC, iSCSI, SAS, IB).3. Familiarity with Traditional RAID Groups, and the differences between them and Dynamic Disk Pools.


2 Lab EnvironmentE-Series Lab Architecture used in this lab.

Figure 2-1:

Table 1: Table 1 Lab Host Credentials

Hostname Description IP Address Username Password

JUMPHOST Windows 20012 R2 192.168.0.5 Demo\Administrator Netapp1!

DC1 Active Directory Server 192.168.0.253 Demo\Administrator Netapp1!

This lab utilizes the SANtricity Simulator, which simulates the experience of managing a physical E/EF arraywithout the ability to simulate I/O shipment between the Host and the Storage array. The simulator runs locally onthe Windows 2012R2 host you see when you first connect to the lab.

Note: We recommend that you follow the lab activities in the order in which they are presented by this labguide.

Some exercises in this lab follow a scenario driven approach. The options presented for those scenarios do notnecessarily reflect universal best practices, since there are many options that need to be considered for differentdeployment scenarios. The E-Series arrays have a default set of parameters that get applied to certain LUNstructures. In some steps this lab deviates from those defaults to provide insight into what you can do with a realsystem.

Attention: The lab simulator allows HTTP (Port 80) connections for convenience. However, the actualstorage arrays will redirect HTTP traffic to HTTPS port 443. In this lab, port 49443 is used.


3 Configure the Storage Array using the Set Up WizardInitial Setup

Use the Setup wizard to configure your storage array, including hardware, hosts, applications, workloads, pools,alerts, and AutoSupport. The wizard prompts you to perform basic configuration tasks, such as naming yourstorage array, configuring your hosts, selecting applications, and creating pools of storage.

Note: You can bypass the Setup wizard by clicking Cancel; however, doing so requires that you manuallyconfigure your storage by using the menus in System Manager.

1. Double-click the shortcut titled “SANtricty System Manager” to launch the System Manger.

6 Create SnapshotsSince you are working with a database workload, first create a snapshot consistency group to maintain databaseconsistency in case a restore is required. Then make sure it is scheduled to automatically create an image on aregular basis.

6.1 Create a Snapshot Consistency GroupSnapshot Consistency Groups are ideal for applications that span multiple volumes, such as databaseapplications that store logs on one volume and the database files on another volume. When you add a volume toa consistency group, the Snapshot feature automatically creates new reserved capacity that corresponds to thatmember volume. You can define a schedule to automatically create a snapshot image of each member volume.

1. Click on the Storage view on the left hand navigation panel, and then click on the SNAPSHOTS tile.

Figure 6-15:

6.4 Create a Snapshot VolumeA snapshot volume allows the host to access data in the snapshot image. The snapshot volume contains itsown reserved capacity, which saves any modifications to the base volume without affecting the original snapshotimage. You can create a Snapshot volume and assign it to a host if you want to read or write snapshot data. Thesnapshot volume shares the same characteristics as the base volume (RAID level, I/O characteristics, and so on).When you create a snapshot volume, you can designate it as read-only or read-write accessible. In this example,a snapshot volume can be thought of as a logical clone of the database.

1. Click on the Snapshot Volumes tab, and then click Create, or (+) Create Snapshot Volume.

8 Test Hot Spare CoverageWhen a disk drive fails, the system needs to be able to handle it without interruption to data access. If you areusing pools, there is spare capacity (called preservation capacity) built into each pool to be used to rebuild involumes in the event of a drive failure. For volume groups, it is best practice to assign one or more global hotspare drives to be used for this same purpose. The array automatically detects many drive problems and if it isnot able to correct a given problem, will fail the drive and then will automatically replace the failed capacity witheither preservation capacity (in the case of pools) or a hot spare (in the case of volume groups).

At other times, you may suspect that a drive has a problem before the system detects it. In such a situation youcan manually fail the drive, but the array does not automatically replace it because the array does not know yourintentions. In this case you will have to manually initiate the takeover operation.

In this section you will do the following:

• Create a global hot spare.• Manually fail a drive in a volume group.• Observe the failure notifications.• Manually fail another drive with no hot spare coverage.• Logically replace the second failed drive.

8.1 Create Global Hot Spare1. Select the Hardware view, and under “Show drives that are…” select the volume group that you

created earlier:

2. Note the drives that are highlighted in blue. These are the drives assigned to your volume group. Also,note the shelf.

3. Under “Show drives that are...”, select Anywhere in the storage array.4. Now left click on one of the unassigned drives (shown in gray) in that shelf, and select Assign hot

spare.

Figure 8-4:

8.2 Manually Fail a Drive with Hot Spare CoverageWhen a disk is in a questionable state or requires replacement for some other reason, it should be pre-failed ifpossible. If a hot spare is present, System Manager can copy the contents of the drive to the hot spare withoutdegrading the resiliency of the encompassing volume group.

1. Left click on one of the drives in your volume group, and select Fail.

1

Figure 8-5:

2. Make sure the Copy contents of drive before failing box is checked. This will ensure that the data fromthe drive to be failed is copied to the hot spare before failing the drive.

3. Type FAIL in the box provided in the pop-up window. It is not case sensitive.4. Then, click Fail to confirm you want to fail the drive.

Figure 8-10:

8.3 Manually Fail a Drive with No Hot Spare CoverageIn the previous step, you used the hot spare when you failed a drive. Now, you will fail a drive and it will haveno hot spare coverage because the hot spare is in use. Then you will logically replace the failed drive with anunassigned drive.

1. Return to the “Hardware” view, select another drive in your volume group, and click on Fail.


1Figure 8-11:

2. On the “Confirm Fail Drive” dialog box, uncheck the Copy contents of drive before failing box. You dothis because there is no hot spare assigned to receive the copied data.

3. Type FAIL in the confirmation box.4. Click on the Fail button.

Figure 8-19:

On a real array, you could now physically replace the failed drives, and the storage array would be optimal. Thesimulator is not able to show this.


9 View PerformanceThe new SANtricity System manager has an improved ability to show performance information. Storage arraylevel performance can be seen on the Home view but a detailed view is also available. Let’s take a look at thedetailed performance information.

1. From the “Storage” view select the Performance tile.

1

Figure 9-1:

9.1 Logical ViewA logical view of array performance allows filtering of performance statistics by logical units (disk pools, volumegroups, and volumes).

1. Initially, you will see the “Logical View” of performance for the entire array, Array1. There are graphs forboth IOPS and MiB/s.

Tip: Throughout this section, if the graphs do not display, change the time period for the graphfrom the default of “1H (1 hour)” to “8H (8 hours)”, and back to “1H” again. There appears to be abug in the simulator.


Figure 9-2:

2. To filter the information you would like to see, select Volumes, then expand Volume Group.3. Check Volume Volume1, then click on Refresh Graphs.4. Also note the possibility to filter on “Pools & Volume Groups”.

Note: Within the simulator not all filters have data provided.

Figure 9-3:

5. To compare latency with IOPS on the top graph labeled “Latency”, select the Compare Latency withdrop down menu, and choose IOPS.


5

Figure 9-4:

9.2 Physical ViewA physical view of array performance allows filtering of performance statistics by physical components (controllersand drives).

1. Select the Physical View tab.2. Collapse both the IOPS and MiB/s graphs. This allows you to see the CPU and Headroom graphs. For

the physical view it is also possible to filter on the host channels and the drives.

Figure 9-5:

9.3 Applications/Workloads View

An application/workload view of array performance allows filtering of performance statistics by individualapplications or workloads running on the array.

1. Select the Applications & Workloads View tab. This view also provides filtering and comparisonoptions that you can explore.

10 Access ManagementSANtricity System Manager has been updated to include a number of new security features. Local role based andexternal LDAP access control give administrators powerful tools to manage which users have access to an E-Series array and what operations each user can perform. The audit log tracks all activity on an E-Series array. Ifthere is an issue, an administrator can quickly identify what went wrong, when it happened, and which user andaccess method is responsible.

10.1 Local Role Based Access ControlSystem Manger comes preconfigured with five different user roles (administrator, storage admin, security admin,support admin, and monitor). Each role has different capabilities. For example, the storage admin can create anddelete volumes and volume groups, but cannot change security settings. The monitor can view array performanceand configuration, but cannot make any changes. The administrator password is set on initial login, but thepasswords of other local roles must be set explicitly within the Access Management settings.

1. Click on the Settings label on the left side navigation panel.2. Click on the ACCESS MANAGEMENT tile.

2

Figure 10-1:

3. Click on the Local User Roles tab to view a list of local user profiles and the roles mapped to each.By default, the only usable profile is the “admin” profile created during initial setup. You must set up apassword on each profile before it can be used.

4. Select the Storage admin role.


5. Click Change Password.

Figure 10-2:

6. In the “Enter your Administrator local user password” box enter Netapp1!, and enter Netapp1! for the“Storage admin local user password”. Then, click Change.


Figure 10-3:

7. A green box stating “Password changed” should appear at the top of the screen.


7

Figure 10-4:

8. Click Logout at the top right corner of the screen. Try signing in to the Storage admin profile. Usestorage as the “Username”, and Netapp1! as the “Password”. Then click Log In.

8

Figure 10-5:

9. If necessary, click on the Settings label on the left side navigation panel. Notice that the “Storage admin”profile does not have access to the “ACCESS MANAGEMENT” or “CERTIFICATES” tiles. For moreinformation about the capabilities of each of the mapped roles, consult the “Learn More” link from any tabinside the “ACCESS MANAGEMENT” tile (while logged in with the “administrator” profile).


Figure 10-6:

10.2 Directory Based Access ControlSANtricity System Manager also supports role mapping to pre-existing user groups defined on an LDAP server.

1. Log out of SANtricity System Manager and log back in as “admin@local”. If necessary, click on theSettings label on the left side navigation panel, and then the ACCESS MANAGEMENT tile. This time,remain on the “Directory Services” tab.


1

Figure 10-7:

2. Click on Add Directory Server.

2

Figure 10-8:

3. On the “Server Settings” tab, add information specific to your LDAP implementation. Enter the followingvalues:


• For “Domain(s)”, enter example.• For “Server URL", enteer ldap://example.com:389.• Leave the Bind account (optional) field blank.• Uncheck the Test server connection before adding box, as no LDAP server is included with

the lab environment.• For “Search base DN”, enter ou=users,dc=example,dc=com.• For “Username attribute”, enter sAMAccountName.• For “Group attribute(s)”: memberOf.


3

Figure 10-9:


4. Click on the Role Mapping tab. Enter cn=sysadmins,dc=example,dc=com for the “Group DN”, and addan assortment of roles by clicking inside the Roles box and selecting from the drop down list. Add moremappings if desired by clicking on the + Add another mapping link.

Note: Each group MUST be given at least the “Monitor” role in order for a member of that groupto be able to access SANtricity Storage Manager

5. At this point in a real configuration you would click Add. Since there is no LDAP server in this labenvironment there's no point to doing this, and it will cause your lab to hang for several minutes.

4

Figure 10-10:

6. In a production environment with a correctly configured LDAP server, users in mapped user groupswould be able to log in to the array with appropriate permissions with a username of the form“username@domain”, and their organizational password.

10.3 Audit LogThe audit log allows users with properly mapped roles to view the activity of all users on an E-Series array.

1. Click on the Settings label on the left side navigation panel, then click the ACCESS MANAGEMENT tile.
