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:

Storage Scale (formerly known as GPFS)

Showing 526

Enable multi protocol CES SMB / NFS rolling upgrades when CTDB upgrade is within a minor version.

When a multi protocol SMB and NFS CES cluster is upgraded, a short full stop of all CES protocols is required due to CTDB not allowing mixed major or minor versions. This can often cause issues with NFS mounts, if it is not possible to unmount the...

Add quota logging capability to keep overall quota accounting consistent

For performance, nowadays, most of quota information is stored and updated in memory. Then, it will be synced back to disk in an asynchronous way later. However, there isn't a recovery mechanism for GPFS quota in abnormal situations. These can mak...

Quota calculation and capacity presentation based on files size

User quota and file set quota are calculated based on allocated capacity on GPFS (kb_allocated). If files are moved to an external tier, e.g. by transparent cloud tiering, the file system utilisation will be decreased. Storage admins should have t...

Capacity quota support for HSM managed file systems

We have two storage scale file systems which are HSM managed using Spectrum Protect for space Management. In total we are storing ~40 PB user data on tape here. Each group has been granted an amount of files and capacity for all our file systems. ...

Remove Node Feature in Spectrum Scale CNSA

Currently in the CNSA Implementation there are no way to reduce a define CNSA-Cluster to one or more Nodes, like a mmdelnode step. The Operator has no function to do these necessary step to reduce a cluster with these request.

Enhance AFM to transfer NFSv4 ACLs from NFS servers like Isilons and store the ACLs correct as GPFS ACLs

Storage Scale and Storage Scale System are great products. But in many cases, another storage is already used and there are no easy ways to migrate PBytes of data - except perhaps with AFM? Almost all installations use e.g. AD integrations and NFS...
8 months ago in Storage Scale (formerly known as GPFS) 1 Functionality already exists

Network resiliency enhancement - need mechanism for prioritizing control traffic over data traffic via QOS/PFC when RDMA is not enabled.

In a heavy workload situations, some clients are removed from the cluster as peer nodes are not able to communicate as heart-beat/control traffic stuck behind data traffic. Also explore, a dedicated VLAN(s) option for Control and Data traffic.
about 1 month ago in Storage Scale (formerly known as GPFS) 0 Under review

To simplify the deployment of workloads in the cloud, IBM must improve the performance of the Scale command "mmaddnode" to allow for faster spin up/down of resources.

Nodes in the cloud need to be spun up quickly as needed. Currently mmaddnode takes too long to add a significant number of nodes as it sequentially adds nodes to the cluster; not only that, but other commands like mmchlicense, mmchnodeclass, and m...

CNSA Support for Per-PV Encryption

Add support for Scale CNSA to provide per-PV encryption allowing for each PV to use its own encryption key from GKLM or HashiCorp Vault. This would be configured as part of the encryption config CR for the PVC. Allow for each fileset associated wi...

Restrict automatic node expels with deadlock amelioration with Nodeclass

We would like to possibly use automatic deadlock amelioration, but we need to ensure certain nodes are not expelled. We do not want to auto expel interactive/login nodes from the compute cluster. We already have a Nodeclass that contains these nod...
