IBM System Storage Ideas Portal


This portal is to open public enhancement requests against IBM System Storage products. To view all of your ideas submitted to IBM, create and manage groups of Ideas, or create an idea explicitly set to be either visible by all (public) or visible only to you and IBM (private), use the IBM Unified Ideas Portal (https://ideas.ibm.com).


Shape the future of IBM!

We invite you to shape the future of IBM, including product roadmaps, by submitting ideas that matter to you the most. Here's how it works:

Search existing ideas

Start by searching and reviewing ideas and requests to enhance a product or service. Take a look at ideas others have posted, and add a comment, vote, or subscribe to updates on them if they matter to you. If you can't find what you are looking for,

Post your ideas

  1. Post an idea.

  2. Get feedback from the IBM team and other customers to refine your idea.

  3. Follow the idea through the IBM Ideas process.

Better vendor-independent monitoring

Currently SMI-S is the only supported vendor-neutral API. We have 5 vendors in our storage environment. The SNIA Swordfish API is not currently implemented by either vendor, with only timid hints at future implementations. We need to have professional SMI-S monitoring of the storage systems at the following levels:

  • Performance (SFP, Fabric Port, Drive, Array, Pool, LUN, Node, CPU, Cluster, Host). The current SMI-S implementation offers FCPort, Drive, Array, Node, Volume but a few are missing: SFP information (Model, RX/TX power levels), Pool information, CPU utilization, Cluster-wide Information, Cache utilization, Host. Which means that the "CIM_BlockStatisticsCapabilities->ElementTypesSupported" is missing at least ComputerSystem and Node. Furthermore, CIM

  • Variable Performance granularity. The default 5 minute statistics refresh is unsuitable in most cases and a 10s configurable resolution would be required. In case of SMI-S, this would require the ability to either change the default StatisticsManifest properties (what gets collected) and the default StatisticsCollection (how often) or the ability to create new manifests and collections. This means that "CIM_BlockStatisticsCapabilities->(A)SynchroneousMethdSupported()" is missing at least Manifest Creation, Manifest Modification and Manifest Removal.

  • Complete end to end mapping of statistical information (e.g.: how to map NPIV WWNs to FCPorts for example). My hosts see NPIV WWNs but the statistics are generated for non-NPIV WWNs.

  • Performance specific for FC environments: Application/VMID tagging to be exposed via API for statistics. We need to know who generates certain I/O patterns.

  • Health (Temperature, Voltage, Power) plus FRU status for common FRUs (Battery, Fan, Canister, Adapter Cards, Drive, PSU). All elements are missing over here. CIM_NumericSensor and it's known descendants are available in the Cimmon, but unpopulated.

We also need the universal API to offer implementation for the common operational tasks, such as:

  • LUN Creation/Deletion/Assignment/Resizing/Migration/Snapshotting/Cloning

  • Host Creation/Deletion/Assignment for both NVMe and SCSI protocols

  • Host Cluster Creation/Deletion/Assignment

This last part is well covered by the current SMI-S implementation.

    Could you please add an openmetrics compliant exporter in the storage array? Competition is doing that.

    The requested information is available from the CLI / REST API.
