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.

Storage Scale (formerly known as GPFS)

Auto-Resume or Failover Across AFM Nodes

Summary: Ensure prefetch requests survive AFM node failures via auto-resume or failover. Description: Currently, when an AFM node goes down, in-flight or queued prefetch requests assigned to that node fail and require manual retry. This creates un...

Fileset Quota Exceeded — Prefetch Requests Stuck Indefinitely

Summary: Prevent prefetch operations from hanging when quota is exceeded. Description: When a fileset quota is exceeded: Prefetch requests neither fail nor retry Requests remain stuck indefinitely, requiring manual intervention This leads to block...

Fileset Quota Exceeded — Inconsistent Read Behavior Across Access Paths

Summary: Ensure consistent error handling for quota-exceeded reads across POSIX and HDFS access. Description: When a fileset quota is exceeded, read behavior differs depending on the access path: POSIX (GPFS path): Correctly returns "disk quota ex...

Support Custom NFS and mountd Ports in AFM Configuration

Summary: Allow AFM to connect to NFS servers using custom ports. Description: AFM currently assumes default NFS and mountd ports, limiting each host to a single NFS instance. This prevents full NIC utilization since multiple NFS instances per host...

AFM Resiliency Scoped to Export Map Instead of Cluster-Wide

Summary: Allow AFM failover only among nodes defined within the same export map. Description: Currently, AFM resiliency requires all AFM nodes in a cluster to be configured in the export map for every fileset. This creates an inefficient AFM-to-NF...

Optimizations to the Spectrumscale ansible installer for larger clusters

For large clusters we are finding that it is taking a rather long time to run. We are looking for optimization like skipping unneeded checks and/or more parallelization for better performance and minimize customer downtime upgrade windows. One are...

AFM: Enhance afmconfig map to allow nfs server stacking

Even with nconnect=16 enabled, the HDFS NFS Gateway caps out at roughly 500 MB/s. This creates a significant waste on modern hardware, leaving high-speed network interface cards (NICs) severely underutilized. To alleviate this waste, introduce two...

When migrating from a internal storage pool using AFM-S3 or S3 Glacier MU mode, allow the data to remain compressed

Data could be compressed on Scale and when migrated via AFM-S3 MU mode or glacier, it should remain compressed if the algorithm is supported on the other endpoint.

Is it possible to enable greater than 512 kNFS threads in CNFS? Ideally, the client would like to set the thread count to a max of 4096 (up from the 512 limit).

MLP has requested that IBM enable the ability to test with more than 512 kNFS threads in CNFS due to performance issues observed in their environment. Specifically, MLP wants to increase the thread count to 2048 or 4096. MLP is aware that CNFS is ...

AFM - Address logging gap to Accelerate Incident Resolution

The current logging implementation for AFM (Active File Management) is insufficient for effective troubleshooting, leading to extended MTTR and, in some cases, unresolvable support tickets. We need to enhance AFM's diagnostic output to provide the...
