Change History for IBM Spectrum Control

View a history of the changes in previous versions of IBM Spectrum Control.

Changes in 5.3.5

The following features and enhancements were available in IBM Spectrum Control 5.3.5:
Important capacity updates
Capacity values were updated to better reflect capacity usage in devices that support hardware compression. Capacity, such as pool capacity and allocated space, is now measured based on the physical capacity of the device, rather than the effective capacity.
The devices affected by this update are:
  • Storage systems such as FlashSystem 9100, FlashSystem 900, and Storwize V7000 Gen3, which contain IBM FlashCore®® Modules with hardware compression.
  • Storage virtualizers such as SAN Volume Controller and Storwize family that use back-end storage systems with hardware compression.
The effective capacity information is still available. Additional columns were added to the Block Storage Systems and Pools pages to show the effective capacity based on the data reduction savings that are achieved with hardware compression. Check the column names that begin with "Effective", for example, Effective Capacity (GiB) and Effective Used Capacity (%).
This update also affects alert thresholds and historical charting for storage systems and pools. In historical capacity charts, you'll see a sharp drop in the values for capacity and used space.
Learn more about the capacity updates.

IBM Storage Insights for IBM Spectrum Control
IBM Storage Insights for IBM Spectrum Control is an IBM Cloud service that can help you predict and prevent storage problems before they impact your business. It is complementary to IBM Spectrum Control and is available at no additional cost if you have an active license with a current subscription and support agreement for IBM Virtual Storage Center, IBM Spectrum Storage Suite, or any edition of IBM Spectrum Control.
For more information, see IBM Storage Insights for IBM Spectrum Control.
Monitoring IBM Storwize V5000E storage systems
You can now monitor Storwize V5000E storage systems. You can view information about the capacity, space usage, and performance of the storage systems. Other features, such as alerting, health monitoring, advanced analytics, and reporting are also supported.
Viewing application performance
You can now view the total workload of an application that is consuming storage resources. Previously, to investigate the workload of an application, you had to review the workloads of the individual volumes. Now you can select an application from the Applications page and click View Performance to see the Total I/O Rate and the Total Data Rate for the application. On the applications details page, you can view the Aggregated Workload charts.
Faster ways to view and acknowledge your alerts
Now it's easier and faster to view and acknowledge your alerts. On the Alerts dashboard, just double-click an alert to see details of the alert on the same screen, including a performance chart for performance alerts. You can view summary details of several alerts at the same time, and acknowledge them all with a single click.
To filter alerts, you can now click one of the alert category tags. For example, to show critical and warning unacknowledged alerts, click Critical and Warning. To show your acknowledged alerts, click Acknowledged.
Automate changing the password for Spectrum Control on Windows
You can now run the changepassword.bat script from Windows Command Line Interface, or from an automated script, to change the passwords for the Spectrum Control user ID or for the database user ID.
Improved support for special characters in Spectrum Control and DB2 passwords
IBM Spectrum Control has improved the support for special characters in passwords, giving you the flexibility that you need based on your security requirements.
IBM Spectrum Control ports have TLS 1.1 and 1.0 disabled by default to increase security
Prior to version 5.3.3, IBM Spectrum Control ports had TLS 1.1 and 1.0 enabled by default. To increase security IBM Spectrum Control ports have TLS 1.1 and 1.0 disabled by default. Therefore, IBM Spectrum Control won't be able to communicate with devices that do not support TLS 1.2. If you want to upgrade your devices to a version that supports TLS 1.2, contact your vendor.

Changes in 5.3.2

The following features and enhancements were available in IBM Spectrum Control 5.3.2:
Configuring alerts using alert policies
Configuring alerts is now easier! You can now use alert policies to configure alerts for groups of resources rather than just for individual resources.
Simply create an alert policy and specify the alerts that you want, and those alerts are automatically applied to all the resources that you include in the policy. Modifying alerts for resources is also a snap because the changes that you make are automatically applied to all the resources in the policy at the same time.
For more information about alerts and alert policies, see How alerts work.
Reporting
  • Create and schedule predefined reports about the capacity that is assigned to hypervisors.
  • Create an inventory report about your servers' ports showing information about the ports that your servers are connected to.
  • Easily generate predefined capacity reports about the resources that you are interested in. It just takes a click to select managed disks by storage systems, pools by storage systems, servers by applications, volumes by servers.
  • Send custom and predefined reports as CSV and HTML attachments. Recipients can then download and open the report in a tool of their choice.
  • Can't wait for the next run of a monthly report? Just click and run the report now to share the information with your colleagues!
