IBM Spectrum Control, Version 5.2.10

New for IBM Spectrum Control Version 5.2.10

New features and enhancements are available in IBM® Spectrum Control™ Version 5.2.10.

The following features and enhancements are now available:

Identifying performance issues with storage systems that run IBM Spectrum Virtualize™
You can now identify key performance metrics that are outside of a standard range on IBM System Storage® SAN Volume Controller and IBM Storwize® storage systems. You can quickly compare the workloads on your storage resources with best practice guidelines. For example, in the following figures, you see that the read response times for an I/O Group sporadically exceed the guideline and you can determine whether you need to take remedial action.
Figure 1. Read response times for I/O groups and the recommended performance guideline
Figure 2. Read response times for a specific I/O group over selectable intervals and the recommended performance guideline
See Identifying performance issues for IBM Spectrum Virtualize storage systems.
Exporting performance data for storage systems and fabrics
You can now export performance data for a resource to a compressed file. If you contact IBM Support to help you analyze a performance problem with a storage system or a fabric, you might be asked to send this file.
See Exporting performance data for storage systems and fabrics.
Investigating capacity and space usage trends
You review the capacity charts to detect capacity shortages and investigate trends in storage growth for your block, file, and object storage resources. You can review capacity trends for these storage resources:
  • Block storage systems, pools, and space-efficient volumes such as compressed, thin-provisioned, and Easy Tier® volumes.
  • File storage resources such as file systems, file system pools, and filesets.
  • Object storage resources such as containers.

You can use the insights that you gain about space usage in your storage environment to determine when you need more capacity and to identify the storage resources that are being underutilized.

For example, in this capacity chart for file systems, you can identify capacity, physical capacity, and space usage trends for two file systems:

See Viewing capacity information.

Investigating the capacity and space usage of tiered storage

Review the capacity and space usage that the tiered storage in your environment consumes. You can see when your tiered storage will run out of space and the weekly growth rate in storage usage for each tier.

See Investigating the capacity of tiered storage.

Viewing virtualized and non-virtualized capacity
You can view the values for the capacity of virtualized storage and non-virtualized storage to understand how capacity is used when storage virtualization is implemented in your storage environment. On the Managed Capacity page, you can now view how total capacity is determined by the sum of two new columns: Managed Capacity (also called non-virtualized capacity) + Virtualized Capacity.

Rollup reporting

Rollup reporting combines capacity and status information from multiple instances of IBM Spectrum Control™ for monitoring and reporting. You can use this information to gain a network-wide perspective of storage usage in your environment when you have multiple IBM Spectrum Control servers deployed. In rollup mode, subordinate servers collect information from the resources they manage and roll that data up to master servers.

See Rollup servers.

Monitoring groups of resources using general groups
You can now group resources, such as the storage systems with lease agreements that end in the current year, so that you can view information about the resources at one location in the GUI.

Create general groups to quickly view information about storage resources that have common characteristics. For example, you might group the subset of ports on a SAN Volume Controller that are used for inter-node communication or the storage systems that are used by a critical business application.

If you used reporting groups, monitoring groups, or storage resource groups in IBM Tivoli® Storage Productivity Center Version 5.2.7 or earlier and upgrade to IBM Spectrum Control Version 5.2.10, copies of the groups are available as general groups in the IBM Spectrum Control GUI. Copies of the groups are available as storage resource groups in the Cognos® BI reporting tool.

Collection of data about the sizes of GPFS™ snapshots
IBM Spectrum Control no longer collects information about the size of GPFS snapshots by default. To view that information, you must enable IBM Spectrum Control to collect information about the size of GPFS snapshots. When you enable data to be collected about the size of GPFS snapshots, the collection might put a significant load on the GPFS cluster during the probe. This load might affect other applications that use the same cluster.
See Collecting information about the sizes of GPFS™ snapshots.
Changes to support for Brocade switches

IBM Spectrum Control V5.2.10 now supports only Storage Management Initiative (SMI) data sources, also called CIM agents, for managing switches from Brocade Communications Systems, Inc. This simplifies the process of adding and managing Brocade switches and fabrics through a single switch management protocol. Storage Resource agents and SNMP agents are no longer supported for Brocade switches. Using the SMI agent that is embedded in Network Advisor V11.1 or later is the preferred method for managing Brocade switches and fabrics. You can use the Add Switches and Fabrics for Monitoring dialog to specify Brocade data sources for your Brocade switches before or after you upgrade to IBM Spectrum Control V5.2.10.

Application membership

You can now view the resource types that were explicitly added to an application or subcomponent in the Members section of the details page. The number next to the resource type, for example, Servers (2), shows the number of resources of that type in the application. To view information about the resources, click the resource type, for example, Volumes (10).

The Filters entry has moved from the General section to the Members section to emphasize that filters affect the direct membership to the application.

Limitations and known issues
