PROFILE
Anton Kuchin
Worked on the ydb-platform/nbs repository to deliver two core features focused on virtualization and storage management. Developed per-VM volumes support in the CSI driver, introducing VM-scoped volume and client IDs to enhance storage isolation and enable VM-aware management in cloud environments. Later, implemented Local NVMe Service IOMMUFD support, enabling flexible VFIO-based device management and aligning the NVMe service with modern IOMMUFD workflows. Both features involved substantial refactoring and updates to device descriptors and test coverage. The work demonstrated expertise in Go and C++ programming, CSI driver development, device driver engineering, and system programming for cloud storage solutions.

Nov 1, 2024Monthly performance summary for 2024-11: Implemented per-VM volumes support in the CSI driver for ydb-platform/nbs, with VM-scoped volume IDs and VM-context client IDs, enabling improved storage isolation and VM-aware management in virtualized environments. The change is tied to commit 5f1c3898df46c14e712fc80c28c39ac17a4da649 ("Support per-VM volumes (#2361)"), and introduces volume/instance ID refactors to associate storage with specific VMs. Major bugs fixed: none reported in this period. Overall impact: provides VM-specific storage isolation, reduces cross-VM risk, and lays the groundwork for VM-aware storage policies. Technologies/skills demonstrated: CSI driver development, ID refactoring (volume IDs, instance IDs), updated client ID generation to VM context, codebase alignment for ydb-platform/nbs.
