## AI overview

This SIG Spotlight article examines Kubernetes SIG Storage, its role in persistent data, volume management, and storage interfaces, and its work on CSI, data protection, Volume Group Snapshot, and Changed Block Tracking. It also discusses storage challenges as AI workloads become more common.

## Source excerpt

In our ongoing SIG Spotlight series, we shine a light on the groups that keep the Kubernetes project moving forward. This time, we catch up with SIG Storage, the group responsible for persistent data, volume management, and the interfaces that connect Kubernetes workloads to the storage systems beneath them. We spoke with Xing Yang, Co-Chair of SIG Storage and Software Engineer at VMware by Broadcom, about the SIG's history, the features shipping in recent Kubernetes releases, and where storage in Kubernetes is headed as AI workloads become the norm. Introductions Could you introduce yourself and share your role(s) within SIG Storage? My name is Xing Yang, a software engineer at VMware by Broadcom. I'm a co-chair in SIG Storage, alongside another co-chair Saad Ali from Google. There are also two Tech Leads in SIG Storage: Michelle Au from Google and Jan Šafránek from Red Hat. What first drew you to storage in Kubernetes, and how did you start contributing? I have always been working in the storage domain, so SIG Storage was a natural place for me to get started when I began to learn Kubernetes. I started attending SIG Storage meetings, trying to figure out what I could do to help. This was before the first Container Storage Interface (CSI) release -- lots of things were still evolving. It was a very exciting time. What subprojects or areas do you actively maintain or review today? I'm a maintainer in Kubernetes CSI. There are multiple CSI sidecars -- such as csi-provisioner, csi-attacher, csi-resizer, and csi-snapshotter -- that we need to release following every Kubernetes release. I'm also a co-chair for a Data Protection Working Group co-sponsored by SIG Storage and SIG Apps. Several features have come out of that WG aimed at filling gaps in data protection support within Kubernetes. One is Volume Group Snapshot, which provides crash-consistent group snapshots for multiple volumes used by an application. Changed Block Tracking (CBT) is another critical feature from
