What's new for IBM Spectrum Control Version 5.3.7
New features and enhancements are available in IBM Spectrum Control Version 5.3.7.
Setting capacity limits
You want to know how much capacity you have left before your storage systems or pools are 80% full? Just, set a capacity limit and you'll know how close you are to reaching your capacity limit.
- If the capacity limit is 80%, you can set an alert to notify you when your storage systems or pools are 70% full.
- If the capacity limit is 80%, you can set an alert to notify you when your storage systems or pools are within, for example, 10 TiBs of the capacity limit.
See Setting capacity limits. To define alerts for Capacity-to-Limit (GiB) and Adjusted Used Capacity (%), see Triggering conditions for storage system alerts and Triggering conditions for storage system internal resource alerts.
Support for Pure Storage devices
You can now add Pure FlashArray//M and FlashArray//X for monitoring and reporting to IBM Spectrum Control.
When you add the storage systems, IBM Spectrum Control collects information that includes metrics that measure the performance of the storage systems. You can view this performance information or you can specify alerts that are triggered when the performance of resources fall outside a specified range.
When you add Pure FlashArray//M and FlashArray//X, you can monitor storage capacity across your storage infrastructure, and you can compare workloads and response times across your environment. Instead of using multiple tools, you can save time by using IBM Spectrum Control to create and schedule reports such as the Capacity report for Block Storage Systems for all of the block storage systems in your multi-vendor environment.
See the Pure Storage support page for details about the supported storage systems. See also Planning for Pure Storage systems, Adding storage systems, and Performance metrics for Pure storage systems.
Monitoring DS8000 capacity on flash drives
You can now monitor the volume capacity that Easy Tier® moves to Tier 1 and Tier 2 flash, high-capacity drives on DS8000® storage systems.
You can monitor the capacity and available capacity of Tier 1 and Tier 2 flash drives in a pool and the distribution of volume extents across each of the Easy Tier drive classes. You can also define alerts so that you are notified when the available capacity on the flash drives in a pool falls below a threshold value that you specify.
Monitoring compliance with your license
For storage systems that are licensed by storage capacity, view the capacity breakdown of the storage environment by the categories of drives that are used. The Category 1 storage category is now added for Storage Class Memory (SCM) drives and managed disks on Spectrum Virtualize for Public Cloud.
Use the License Compliance page to determine whether the total capacity of the storage systems that IBM Spectrum Control manages exceeds the entitlement of your product license. The capacity is shown in tebibytes (TiB), and is converted to storage capacity units (SCUs). By comparing the TiB or number of SCUs to the number that is covered by your product license entitlement, you can discover how much additional storage can be added before you exceed your license entitlement.
See License compliance.
