Introduction

Introduction to Storage Resource MonitorSolarWinds Storage Resource Monitor (SRM) monitors performance and capacity of your storage arrays, helping you locate and resolve storage related issues. SRM supports multiple devices and vendors, providing real-time, unified visibility for all layers of your storage infrastructure.

l For a complete list of supported devices, see Add arrays to SRM. l For information on installing or upgrading SRM for the first time, see the Use the SolarWinds Orion Installer to

install or upgrade Orion Platform products article. l See also the Getting Started Guide for SRM.

This administration guide contains the following sections:

Add arrays to SRM Enable the arrays in your storage environment to be discovered and monitored by SRM.

Administer SRM As soon as devices are detected, data shows up for all storage layers on the real-time performance and capacity dashboards. Drag-and-drop vendor-agnostic resources can be added and customized to let you monitor all your storage devices however you want.

Set up alerts to notify you before performance and capacity issues become problems. Use pre-built alerts, create alerts, and fine tune the warning and critical thresholds for device types or individual devices.

Create predefined and custom reports to see performance and capacity trends in your storage environment.

SRM solutions Add addition polling engines or web servers as your storage environment expands.

The SRM Profiler module is also included with SRM, which gives access to more array vendors and models. This can be integrated with SRM and share the same licenses.

Integrate SRM with other SolarWinds Orion modules such as SAM to take advance of SolarWinds Orion monitoring solutions using AppStack and Network Atlas.

SRM widgets The SRM Web Console dashboards provide over 40 widgets that give real-time and historical SRM data in immediate, vendor-agnostic formats. When SRM is used with other SolarWinds Orion products you can build your own dashboards and NOC displays to meet your monitoring requirements.

SRM architectureThe following graphic outlines the architecture of Storage Resource Monitor.

page 8

Licensing Storage Resource Monitor (SRM)SRM is licensed in the same way as other Orion Platform products, as described in License Orion Platform products. However, SRM license levels apply to the number of hard drives and solid state drives and across all Shared Storage (SAN, NAS) systems rather than nodes. This is the number of actual physical drives, regardless of capacity or technology. Disk drives in servers are not counted.

All disk drives managed by the monitored SAN/NAS system will be automatically included for licensing.

For example, the SRM25 license will cover storage environments of up to 25 drives. The SRM50 license covers 26 to 50 drives, and so on.

The SRM license covers both the SRM Orion module and the SRM Profiler module. For information on how the license is shared if you are running both modules, please see Use SRM with SRM Profiler.

Add arrays to SRM

Add arrays to SRMThe following table provides links to SolarWinds knowledge base articles that give the credentials and other information needed to add arrays to SRM. In some cases arrays need to be enabled before they can be added, or a provider set up either on the array or on an associated server, to enable performance data collection.

Arrays that are only supported by the SolarWinds Orion SRM Profiler are listed in Which arrays are supported by SRM and SRM Profiler?

SMI-S Storage Management Initiative Specification

SNMP Simple Network Protocol

XMS XtremIO Management Server

API Application program interface

In order for a storage array to communicate with SRM, it is sometimes necessary for a provider to be installed. Depending on the vendor and the array model, the provider may be part of the management software provided with the array (Type 1 below) or a separate software application hosted from a server external to the array (Type 2) . In some cases the provider is already embedded on the storage array (Type 3). The following graphic demonstrates these three cases:

Manage arrays, providers, and credentials in SRMSRM provides an easy-to-use central location for managing storage arrays, providers, and credentials.

EMC XtremIO and Pure Storage capacity savings technologiesEMC XtremIO and Pure Storage arrays use capacity-savings technologies including:

ADMINISTRATOR GUIDE: STORAGE RESOURCE MONITOR

page 17

l De-duplication - removing redundant data. l Compression - making the object smaller using standard compression algorithms. l Thin provisioning - using virtualization to give the appearance of having more physical resources than are

actually available.

As an example, let us look at the LUN creation process for these arrays. Suppose we were to provision a logical object (LUN) on an EMC XtremIO or Pure Storage array, and wanted to make it 100 GB.

After creating the LUN, we can inspect the LUN Details view to see that the Total Size property shows 100 GB, the size of the LUN required.

We can investigate the Consumed Capacity value. Immediately after the LUN is created this value will be a very small fraction of the 100 GB. It will, of course, grow as the user adds data to the LUN. The value displayed should be exactly the net amount of data which has been sent to the LUN. Since this is a logical value, as seen by the host computer operating system, it cannot be greater than the Total Size.

If we then look at the Storage Pool Details view we should see the Total Subscribed Capacity has increased by 100 GB.

Depending on the array total capacity and the Total Subscribed capacity, the Oversubscribed Capacity can stay at 0, or grow to a value between 0 and 100 GB. This value shows how much the sum of the LUNs Total Size values for the pool is bigger than the Total Usable Capacity.

Over the lifetime of the LUN, Total Capacity of the LUN and its share in the Total Subscribed Capacity for the array will not change, unless the storage administrator expands or shrinks the LUN.

In most cases the Consumed Capacity of the LUN will not decrease, with the exception for LUNs owned by certain operating systems. For example, if VMware is used, VAAI is able to communicate to the array a list of unused blocks of data - these blocks will be removed, decreasing the Consumed Capacity.

The influence of adding the 100 GB LUN on the Usable Capacity for the array cannot be predicted with 100% certainty. Because of global de-duplication, adding the data can leave the free usable capacity unchanged in extreme situations. Therefore, any prediction for run-out time is statistically valid at the whole array level.

Administer

Administer SRMThis section provides information on the day-to-day administration of the Storage Resource Monitor.

The Orion Web Console is where you interact with your SolarWinds Orion products. For SRM, this is where you monitor your storage network using dashboards, views, and widgets.

You can use the Orion Web Console to complete daily tasks such as:

l Add and manage users l Manage polling, alert thresholds, and other settings for arrays and storage objects l Monitor hardware health and run reports l Create alerts and generate reports from this console

Log in to the Orion Web ConsoleIf you added Storage Resource Monitor (SRM) to an existing SolarWinds Orion platform installation, you are familiar with the Web Console and can immediately access SRM.

1. Navigate to My Dashboards > Storage > Storage Summary.

If you installed SRM as a standalone product:

1. Launch the Web Console:

l Click Start > All Programs > SolarWinds > Orion Web Console.

or

l Open a web browser on your SolarWinds SRM server and enter http://ipAddress or http://hostname, where ipAddress is the IP address of your server and hostname is the host name of your server.

2. Enter a user name and password.

The first time you log into SRM (and until you change the default Admin password) you can log in with the user name Admin and no password.

3. Click Login.

The first time you log in to the Web Console you are prompted to use the Enrollment wizard to add storage devices to SRM for monitoring. For more information see Add arrays to SRM.

The Orion Storage Home view displays a summary of information monitored by SRM. This summary includes the All Storage Objects resource, which enables you to navigate to every storage object monitored, and also shows all active alerts, the last 25 events, objects most at risk, and hardware health.

The Web Console also provides access to the alerts, reports, and settings menus.

ADMINISTRATOR GUIDE: STORAGE RESOURCE MONITOR

page 19

Views and widgets in SRM

ViewsThe initial default views available from the SRM menu show summaries of storage information across your environment:

l Storage Home: a high level overview of all monitored storage objects, along with alerts and events. l Performance Dashboard: an overview of storage objects showing performance data. l Capacity Dashboard: an overview of storage objects showing capacity data.

When you drill down from these, the views are for individual storage objects, showing capacity and performance information.

Views can be customized to suit the needs of your users. For example, if you want to give different groups of users different levels of access to storage information, you can create custom views that restrict what they can and cannot see.

Click an object name in any resource to display the Details view for that object.

For information on editing, adding and copying views, see Create Views.

For information on setting permissions, see Manage user accounts.

Widgets

Widgets were referred to as resources in earlier versions of this documentation.

Views are comprised of widgets, and each widget contains data from one or more monitored objects such as performance, capacity, and disk count. You can add or remove widgets from views as needed.

The following image shows three widgets on the Storage Home dashboard: All Storage Objects, Storage Objects by Performance, and Array Raw Disk Capacity Summary.

page 20

For information on the SRM widgets, see SRM widgets.

Manage SRM settingsSettings in SRM, such as thresholds, can be applied at the global level for all storage objects in your environment, or at the object-specific level if an individual device needs attention.

4. Select the arrays, and click Edit Properties.

5. The Edit Properties page is displayed.

6. Amend the polling frequencies as required, and click Submit. The frequencies entered will be applied to all selected arrays.

Manage thresholds for SRMOrion Platform products provide two threshold levels: critical and warning. Many SRM widgets can display a critical or warning status when a monitored value on a device exceeds thresholds. You can override all storage objects of the same type (for example, all storage arrays in your monitored environment) or for individual objects for predefined static thresholds.

Thresholds can be used to define trigger conditions when creating alerts.

To change the value for a threshold, you can use a static threshold or a dynamic baseline threshold.

l A static threshold is a constant value. For example, the global warning threshold for LUN latency might be 50 ms, and the critical value might be 100 ms. You should be familiar with the performance of that object type or specific object to set a value for a static threshold is across your environment.

l A dynamic baseline threshold uses deviation from the mean value to determine critical and warning thresholds. Dynamic baseline thresholds can only be set for individual objects.

Dynamic thresholds require data to be collected for a week for an accurate baseline to be determined. This is then used to calculate mean and standard deviations. The warning and critical threshold values are defined as two or three standard deviations above the mean.

page 26

Set SRM thresholdsYou can adjust the settings for the critical and warning thresholds values for all the members of a storage object type.

To adjust the thresholds for an individual object, see Set SRM thresholds for specific storage objects.

1. Navigate to Settings > All Settings.

2. Under Thresholds and Polling, click SRM Thresholds.

3. Click the link for the storage object type to set critical and warning levels.

4. Enter the values for Critical Level and Warning Level.

Except in the case of Cache Hit Ratio, Critical and Warning thresholds are triggered if the value is greater than the value specified. If you need to create thresholds that are triggered by the value falling below a specific value, set thresholds for specific objects.

Set SRM thresholds for specific storage objectsYou can adjust the critical and warning thresholds values for an individual storage object.

1. Use the All Storage Objects resource to navigate to the Details page for the required storage object.

2. Click Manage at the top of the Details resource.

3. Scroll down to Alerting Thresholds, select Override Orion General Thresholds for the required metric, and adjust the warning and critical threshold values as needed.

Unlike setting thresholds at an object type level, you can change the operator for individual object thresholds here. This gives additional flexibility for you to create minimum values using "Less than" and other operators.

ADMINISTRATOR GUIDE: STORAGE RESOURCE MONITOR

page 27

Set dynamic baseline thresholds

Use dynamic baseline thresholds to create warnings and alerts that trigger when polled data from a storage object deviates from standard behavior.

SRM uses the average data results of the mean, standard deviations, and historical distribution to calculate dynamic baselines. Automatically set thresholds based on the recent, normal performance of the dynamic baselines. By default, baseline calculations are based on data collected during the previous seven days.

Any anomalies that occur during the baseline period are included in the calculations and skew the thresholds generated. If significant changes happen in your environment, such as merging a new company, onboarding a large number of users, or making substantive improvements to the infrastructure, you should "re-baseline" to ensure the recommended values are accurate.

1. Use the All Storage Objects resource to navigate to the Details page for the required storage object.

2. Click Manage at the top of the Details resource.

3. Scroll down to Alerting Thresholds, select Override Orion General Thresholds for the required property, and click Use Dynamic Baseline Thresholds.

You can also adjust the way baseline thresholds are calculated.

Click Latest Baseline Details and change the period of sampled data and select the deviations used to calculate the critical and warning thresholds.

An understanding of standard deviations and statistics is required before changing these settings.

Monitor hardware health for SRMWith the release of SRM 6.4, SolarWinds introduced hardware health monitoring for selected arrays, giving you immediate insight into hardware issues in your storage environment. Monitoring hardware health on storage arrays gives access to the status and values of onboard sensors. In addition to displaying this data on the Hardware Health page for the array, you can set thresholds to use in monitoring and alerts.

page 28

Hardware health data is collected when the storage array is polled for statistics/performance data. By default this is every 15 minutes, although this can be amended for individual devices.

SRM hardware health metrics The hardware health metrics available for monitoring an array depend on the vendor and model.

This table assumes that the latest firmware is installed on the array. Status monitoring may vary on older versions.The table shows only sensors that provide statuses; some sensors, such as SpCards and Storage Controllers, are present in hardware health but they are only used to aggregate sensors.

For SRM 6.8, hardware health data is available for the following arrays and sensors:

Solutions

SRM solutionsThis section contains topics that cover extending your SRM storage environment by adding additional pollers and web servers, using SRM Profiler if you need to add arrays not supported by SRM, and using SRM with other Orion modules.

Use SRM with SRM ProfilerIn addition to the Orion Platform SRM module, there is also a separate module called SRM Profiler. This provides support for additional storage devices, and can be integrated with the SRM Orion Platform module, sharing the same license and allowing both products to run together. For more information on the SRM Profiler, see the SolarWinds Storage Manager/SRM Profiler documentation.

To integrate the SRM Orion Platform and SRM Profiler modules, you must be running version 6.0 or later for both products.

PrerequisitesThe following prerequisites must be met before you can integrate SRM with SRM Profiler:

l Open the following ports: o 8443 o 17778 o 9000

l If your license is applied to the SRM Orion Platform module, you must reclaim the license and apply it to the SRM Profiler module before integration.

After the SRM Orion Platform module and the SRM Profiler module are integrated, the SRM Profiler module is responsible for maintaining the license .

SRM Integration does not support TLS 1.2 and 1.1.

The Storage Manager Integration moduleThe Storage Manager Integration module for Orion is specific to earlier releases of the Storage Manager. If you install the Storage Manager Integration module after the SRM Orion Platform module and the SRM Profiler module, two storage tabs become available on the Orion web page: one for the SRM Orion Platform module content, one for the SRM Profiler module content.

If you are running the Storage Manager integration module for the Orion Platform prior to integrating, SolarWinds recommends you uninstall the Storage Manager integration module first.

ADMINISTRATOR GUIDE: STORAGE RESOURCE MONITOR

Your reclaimed license is available in your customer portal and ready for activation.

Authentication between SRM and SRM Profiler When the SRM Profiler module and the SRM Orion Platform module are integrated, both modules generate a hidden account and user name and password in order to communicate information back and forth.

After integration is complete, all requests to the SRM Orion Platform module and the SRM Profiler module are authenticated based on this service account information. Information transferred between the SRM Orion Platform module and the SRM Profiler module is encrypted and passed via HTTPS over TCP port 8443.

If SRM and SRM Profiler are integrated:

page 38

l The SRM Profiler module is the primary owner for holding license keys, and is responsible for handling all license related queries.

l The products tries to sync every 5 minutes .

If SRM Profiler goes offline:

l The SRM Orion Platform module attempts to connect to the SRM Profiler module until connectivity is re-established.

l The SRM Orion Platform module will not add any arrays while the SRM Profiler module is unreachable. l If the SRM Profiler module is unreachable for more than 24 hours, the SRM Orion Platform module marks all

arrays as unlicensed, and polling stops.

If SRM goes offline:

l The SRM Profiler module continues to work. l The SRM Profiler module uses the last retrieved license validation from the SRM Orion Platform module for 30

days. l After 30 days, the last retrieved license validation from the SRM Orion Platform module is discarded, and the

SRM Profiler module reclaims the license from the SRM Orion Platform module, and continues to work. l The SRM Profiler module continues connection attempts to the SRM Orion Platform module until connectivity

is re-established. When the SRM Orion Platform module goes offline, you can reclaim the license from the SRM Orion Platform module immediately.

Integrate SRM and SRM Profiler If you have both SolarWinds SRM and SRM Profiler installed, you can integrate them as follows.

1. From the Web Console, navigate to Settings > All Settings.

l The SRM Profiler module remains licensed, so that polling continues for the storage devices to which it is assigned.

l If the 30 day evaluation period has not expired for the SRM Orion Platform module, polling continues for the devices to which it is assigned.

l If the 30 day evaluation period has expired for the SRM Orion Platform module, polling stops for devices to which it is assigned.

Key licensing scenarios when SRM Profiler and SRM are integrated

SRM performs the following tasks on start up:

l The SRM Orion Platform module retrieves licensing information from the SRM Profiler module. This information is kept in the SRM Orion Platform module license cache.

l The SRM Orion Platform module retrieves a list of licensed arrays for both the SRM Orion Platform module and the SRM Profiler module. This information is kept in the SRM Orion Platform module license cache.

The license cache is used by the SRM Orion Platform module to perform license checks when adding or removing arrays.

Add an array to the SRM Orion module

When you add an array to the SRM Orion Platform module, the system checks to see if the array is licensed and monitored to the SRM Profiler module.

l If the array is licensed in the SRM Profiler module, then the SRM Orion module adds the array to its inventory. l If the array is not licensed in the SRM Profiler module, a calculation is performed by the SRM Orion module to

verify if adding the array exceeds the total licensed disk count. l If the total licensed disk count is not exceeded, the SRM Orion module adds the array, updates the license

cache for the SRM Orion module, and sends a notification to the SRM Profiler module about the inventory change.

l If the total licensed disk count is exceeded, the user receives a warning message and the array is not added.

Use Additional Polling Engines with SRMTo collect data at a rate or volume beyond the capacity of a single SRM server, you can add an Additional Polling engine (APE). You can also use APEs for organizational purposes, so storage at each site is monitored by its own APE.

Although you can use a regular SolarWinds APE to retrieve storage information, SolarWinds provides a free SRM APE. This only retrieves storage information and cannot be used with other products. The SRM APE software is available via your customer portal. You may use as many SRM APEs as required without additional licenses.

Install and configure an Additional Polling Engine (APE)APEs use the same Microsoft SQL database as your SolarWinds SRM server. They do not require Microsoft Internet Information Services (IIS).

1. Download the APE from the SolarWinds Customer Portal.

2. Browse to the executable, and launch it.

The executable extracts to a folder containing an HTML readme, an Installer Guide, and Additional Polling Engine installers for all SolarWinds products that support Additional Polling Engines.

3. Launch the SRM installer.

4. Follow the instructions on the screen, and supply the requested information to install and configure the APE.

5. From the Web Console, navigate to Settings > All Settings.

6. Select Manage Storage Objects from the Node & Group Management section.

7. Select the storage devices to be monitored with the poller.

8. Click Assign Polling Engine from the More Actions drop-down menu.

The Select a New a Polling Engine window opens.

9. Select a polling engine for the selected arrays.

10. Click Change Polling Engine.

Your selected storage devices are now monitored by the APE instead of the main SolarWinds SRM server.

Use an additional web server with SRMAn Additional Web Server can reduce the load on your SolarWinds SRM server and ensure access to the Web Console in the case of a server failure. Install the Additional Web Server software on a server independent of the primary SolarWinds SRM server.

Requirements l An additional web server license. l A server with a 64-bit operating system. l A network connection between the Additional Web Server and the SolarWinds SRM server or main poller.

ADMINISTRATOR GUIDE: STORAGE RESOURCE MONITOR

page 41

l A version of the SRM Additional Web Server software that matches the version of the SolarWinds SRM server or main poller.

Install an Additional Web Server 1. Log onto the server on which you want to install the SRM additional web server software.

2. Download the SRM additional website software from the SolarWinds Customer Portal.

3. Double-click the executable for the SRM additional web server software to launch the Installation wizard.

4. Complete the installation wizard.

Use AppStack with SRMThe Application Stack, or AppStack, is a term used to describe the various layers that make up a complex application delivery infrastructure. The AppStack Environment view is an interactive visual mapping within the Orion Platform that provides an in-depth perspective through the entire environment to help identify the root cause of performance and availability issues.

AppStack automatically gathers information about objects in your environment and their respective relationships, and displays them in the AppStack resource and AppStack view. Some relationships, such as groups and dependencies, can be defined by the user.

page 42

You can monitor the health status of storage devices along with associated entities of the storage device. The Appstack Environment reports the status of the arrays, storage pools, volumes, LUNs, servers, hosts, applications, and groups.

SRM automatically constructs the view and presents it via the Web Console and no configuration is needed.

As a stand-alone product, AppStack is available in the software versions listed below. If you own two or more of the listed products, AppStack does not function properly unless each version of the software is upgraded to the versions listed:

l Storage Resource Monitor 6.0 or later l Virtualization Manager 6.2 or later l Server & Application Monitor 6.2 or later l Web Performance Monitor 2.2 or later

To access the AppStack Environment:

In the Web Console, go to My Dashboards > Home > Environment.

To use the AppStack Environment resource in SRM:

1. In the Web Console, go to My Dashboards > Storage Summary.

2. Using the All Storage Objects resource, navigate to an object in the environment you want to explore, and view the Details page.

If the AppStack Environment resource is not displayed, click on Customize Page and add the resource, as described in Create, delete, modify, or restrict views.

For a full description of the AppStack Environment, and the features associated with it, see The AppStack Environment.

Use PerfStack™ with SRMThe Performance Analysis dashboard (PerfStack™) enables you to correlate historic data from SRM and many SolarWinds products in a single view. This makes it simple to troubleshoot issues, create ad-hoc reports, and make data-driven decisions on infrastructure changes.

Drag and drop performance metrics, events, and log data to a chart to perform deep analysis of what was going on in your environment when an issue occurred. Stack or superimpose metrics to immediately see correlations across your infrastructure.

The entities and metrics available to you depends on the SolarWinds products installed.

Depending on your account limitations, you may not have access to your complete infrastructure data set. However, all users can create Performance Analysis dashboards.

ADMINISTRATOR GUIDE: STORAGE RESOURCE MONITOR

page 43

Create Performance Analysis dashboards 1. Click My Dashboards > Home > Performance Analysis to display the Performance Analysis dashboard.

2. Click Add Entities.

This opens the Add Entities window where you can filter and search all the available entities and select those you want to use.

3. Click Add Selected Items to close the window.

The selected entities are now displayed, and organized by category.

4. Click a gray triangle to expand an entity category.

To add all entities related to an entity, hover over the entity, and click the icon.

5. Highlight an entity to display the available metrics.

Metrics are organized by categories.

6. Click a gray triangle to expand a metrics category.

8. Repeat with additional entities and metrics to build the required charts.

9. Click the time range above the chart to set the time range for the chart. This can be relative (for example, Last 24 hours) or a specific date and time span.

ADMINISTRATOR GUIDE: STORAGE RESOURCE MONITOR

page 45

10. Save the project.

Performance Analysis projects and changes to these charts are not automatically saved. If you create a new project or navigate away from the dashboard, any changes made since you last saved the project are lost.

Share Performance Analysis projectsAny saved analysis project can be shared by other users. Click Load to search for saved projects. Use other users' projects "as-is," or as the basis for new projects.

Projects you have not created can only be saved using More > Save As.

You can only delete projects you have created. If a user creates a project and is removed from the SolarWinds user list, the projects that user saved are not removed from the server.

You can also share the URL of a project. For example, you may use PerfStack™ to identify the root cause of an issue you are experiencing, and send the URL in a help desk ticket for a technician to view.

TroubleshootingI do not see all the data I expect

The collected data depends on the products you install and how they are configured.

I do not see key entities

Performance Analysis charts respect account limitations. If your account is restricted from viewing certain entities or nodes, you cannot view their data in Performance Analysis dashboards.

Not all metrics I add are charted or data does not display correctly after I add more metrics

page 46

This is usually due to browser limitations. Changes to the Performance Analysis dashboards are reflected in the URL. If you have a large amount of data, the URL may exceed the character limit for URLs in your particular browser.

Map your storage environment with SRM and other Orion modulesEnd-to-end mapping describes relations between SRM objects such as storage array, storage pool, LUNs, NAS volume, file share, and objects from other Orion Platform modules such as physical servers, virtual machines, datastores, applications, and so on. When mapped, these relationships can be viewed in AppStack.

Storage Resource Monitor provides end-to-end mapping of your storage environment so you can see how your storage devices and servers are connected. When you install SRM with Server and Application Monitor (SAM) 6.2 or later, you can observe end-to-end mapping for physical servers.

To map virtual servers (for example, VMware or Hyper-V) to your SAN or NAS device, you must have Virtualization Manager (6.2 or later), installed and integrated with the Virtualization Manager Orion Platform module (2.0 or later).

Learn more:

l Automatic end-to-end mapping l Manual end-to-end mapping

Automatic end-to-end mappingAutomatic end-to-end (E2E) mapping has the following supported relations:

l SRM LUNs <> Volumes (for physical machines - windows servers polled via Windows Management Instrumentation (WMI) and using FC/SCSI protocol)

l SRM LUNs <> Virtualization Manager (VMAN) Datastores l SRM LUNs <> Virtualization Manager (VMAN) Virtual Machines (RDM mapping) l SRM FileShares <> Virtualization Manager (VMAN) Datastores

Automatic end-to-end mapping of your physical servers

Prior to SRM 6.7, automatic end-to-end mapping was only available for Master Boot Record (MBR) drives. With SRM 6.7, support had been added for GUID Partition Table (GPT) drives in E2E mapping.

When installing SRM with SAM, the Network Storage Topology Resource is enabled automatically for any Windows device added after the install.

Any Windows device monitored by SAM prior to the installation of SRM will have the Network Storage Topology Resource disabled. To make SRM recognize the Windows servers added before the SRM installation, you must do one of the following:

l Select the node, go to Node Details and select List Resource on the Management widget. Here you can enable the Network Storage Topology Resource option.

l Run a network discovery on existing nodes to add the Network Storage Topology Resource. Please note the resource is not enabled after it is added.

ADMINISTRATOR GUIDE: STORAGE RESOURCE MONITOR

page 47

The Network Storage Topology Resource does not work for Windows servers monitored with SNMP. All Windows servers must be monitored via Windows Management Instrumentation (WMI) to use this feature. Windows Server 2003 and above can be monitored using WMI.

Automatic end-to-end mapping of virtual servers using VMware or Hyper V

Mapping your storage devices to your virtual environment requires SolarWinds Virtualization Manager (VMAN 6.2 or later) and the Virtualization Manager Orion Platform module (2.0 or later). After you install VMAN, the mapping is automated for virtual devices and no modifications are needed in SRM.

Manual end-to-end mappingRelationships are discovered automatically for Windows Management Instrumentation (WMI) nodes, except for SNMP nodes. This is because SRM is unable to get FC/iSCSI topology from non-Windows physical servers. You can manually create relations between SRM entities and other Orion Platform modules using manual end-to-end mapping.

1. Navigate to Settings > All Settings > SRM Settings.

2. Select Map Server Volumes to Storage Targets.

Thick NAS Volumes (by Capacity)When displayed on a summary dashboard, this resource provides a lists of all thick NAS Volumes in the environment.

When displayed on a storage object details page, this resource provides a lists of all thick NAS Volumes associated with the object.

A thick NAS volume has all of its capacity reserved and allocated when created.

For each volume, the volume status and name, storage pool status and name, total size, file system used capacity and filer system used percentage are displayed. Used capacity is highlighted in yellow or red if the warning or critical threshold had been reached or exceeded.

Projected File Run Out shows the estimated time remaining before the volume runs out of space. Statistics are gathered from the last 3 months and are projected to a linear prediction that calculates the date when Run-Out will be reached.

Volumes can be sorted by any column.

You can search the list of volumes by entering any part of the LUN name in the search box.
