Table of Contents

ViPR reporting features

Learn how to research ViPR-managed commodity storage capacity in ViPR SRM. Learn the difference between ViPR software-defined storage systems and a ViPR virtual data center and how to find both in ViPR SRM. You can also monitor the health and status of ViPR system nodes using ViPR SRM.

The following features for reporting on ViPR-managed storage assets assume that the SolutionPack for EMC ViPR is installed.

ViPR storage terminology

ViPR software-defined storage and ViPR virtual data center storage are different concepts.

What's included in ViPR software-defined storage?

In the ViPR SRM enterprise-wide reports, the array type "Software-defined" refers to arrays that are defined using ViPR and consist of the following storage assets:

How is commodity storage represented?

Commodity storage connected to ViPR nodes and managed by ViPR software is represented as virtual pools. Using the ViPR user interface, an administrator assigns the virtual pool space into data stores. Data stores can be assigned to virtual arrays. Commodity storage connected to ECS also uses the data store concept.

What's included in a ViPR virtual data center?

A ViPR virtual data center can incorporate arrays from many sources in addition to the ViPR software-defined storage arrays. For example, a virtual data center might include a combination of file, block, and object arrays defined on devices such as Isilon, VNX, and Centera, as well as ViPR software-defined arrays backed by commodity hardware.

For details about ViPR virtual data centers and the arrays, pools, and storage systems that comprise a virtual data center, use the reports under Report Library > EMC ViPR > Virtual Data Centers > <virtual_data_center_name> > Inventory.

Research ViPR commodity data stores

You can research the ViPR commodity data stores in ViPR SRM.

A ViPR-defined virtual data center can optionally include storage space on ViPR-managed commodity hardware.

In ViPR SRM, you can see the data stores that are assigned to a virtual data center, and monitor available capacity on them. You can launch ViPR and adjust capacity in a data store if needed.

Additionally, you can locate the ViPR commodity virtual pool, and drill down to see the commodity hardware that underlies the virtual pool and its data stores.

Procedure

  1. Log in to the Console, and navigate to Explore > Storage.
  2. In the Storage Systems report that appears, click a row whose first column has a value of Software Defined for Storage System Type.
    Note Image
    The Software Defined storage system type could be a ViPR-defined storage system or an ECS-defined storage system.

    In the following report, the alias in the third column indicates a probable ViPR-defined storage system.

  3. In the ViPR Device Summary list of reports, click Inventory Details.


  4. In the Inventory Details list of reports, click Data Stores.


    In the following report, you see that the Dallas virtual data center uses three ViPR datastores.

  5. To find the underlying storage system for these data stores, and monitor data store health:
    1. Return to the Inventory Details list, and this time click Virtual Pools.

      This report shows all of the virtual pools in the virtual data center. One of those pools is the automatically created pool for ViPR commodity storage space.

    2. Click on the row that has the description This vpool is used to create the data stores.
      The resulting page shows the details about the virtual pool, including its subscription rate, and capacity.

    3. Scroll down to view additional reports about the virtual pool.
      In this case, you see a List of File Systems report and a Storage Pools report.

      You see that the ViPR commodity virtual pool is a file system on an Isilon storage system, and is assigned to the virtual array named Dallas Object.

  6. To perform maintenance actions on this file system:
    1. Right-click the row in the List of File Systems report, and then choose Show File System in ViPR.
    2. Log in to ViPR using ViPR credentials.
      ViPR opens to the file system's definition page.

Results

You learned that at least some of the object storage for the Dallas ViPR virtual data center is on an Isilon system, managed by ViPR. You can see capacity and availability of the system in ViPR SRM. You can launch ViPR to perform required maintenance.

Research ViPR system health

Reports in the ViPR SRM report library show the health of the ViPR software nodes, services running on the nodes, and physical disk performance.

Procedure

  1. Log in to the Console, and then navigate to Report Library > EMC ViPR > Operations > Health Dashboard > ViPR Nodes.
    This report lists all virtual data centers and the ViPR nodes that control them. You can see that the nodes supporting the Boston virtual data center have a history of 100% availability but memory usage has exceeded thresholds.

  2. To drill into the vipr3 node, click that row.
    A set of reports about that node appears. Scroll
  3. Scroll down to display the Services report.


    The report shows that the node's main consumer of memory is the dbsvc service. You need to follow through with providing more memory for the nodes that service the Boston virtual data center.

  4. In the navigation tree, navigate to Report Library > EMC ViPR > Operations > Situations to Watch.
    These reports provide you with immediate notice of node-related health problems.
  5. To make a report a favorite:
    1. Click the report name to display the report. For example, click Degraded or Bad Disks.
    2. In the upper right corner of the report window, click TOOLS > Favorite this Report.
    The report now appears in the Favorite Reports node at the top of the navigation tree.

Results

You researched the health of ViPR system nodes and discovered that the ViPR instance that services the Boston virtual data center needs additional memory resources. You also moved the Degraded or Bad Disks report into your Favorites folder to make it quicker to access.

Research ECS-managed commodity storage

You can research the capacity, availability, and status of commodity storage managed by an EMC ECS appliance in ViPR SRM.

A ViPR-defined virtual data center can optionally include storage space on ECS-managed commodity hardware.

All of the commodity storage that is directly managed by an ECS appliance is automatically combined into a single virtual array named CommodityvPool. From that virtual pool, an ECS administrator can define ECS data stores. A data store is a portion of the available commodity space managed by the ECS. A ViPR administrator then assigns one or more ECS data stores to a ViPR virtual data center.

In ViPR SRM, you can see the ECS data stores that are assigned to a ViPR virtual data center, and monitor availability and capacity on them.

Procedure

  1. Log in to the Console, and navigate to Explore > Storage.
  2. In the Storage Systems report that appears, click a row in which Storage System Type (first column) has the value Software Defined.
    Note Image
    The Software Defined storage system type could be a ViPR-defined storage system or an ECS-defined storage system.

    You can use the alias in the third column to help determine which system is an ECS system.



  3. In the ViPR Device Summary list of reports, click Inventory Details, and then click Data Stores.


    In the following report, you see four ECS data stores in the Hopkinton ECS virtual data center.

  4. Return to the Inventory Details list, and click Fabric Nodes.


    The Fabric Nodes report shows that the nodes are available and operational.

Results

You identified the ViPR system nodes that support an ECS storage system and verified the health of those nodes. You also reviewed the capacity defined for each of the data stores out of the ECS virtual storage pool.
