CephFS Shared Filesystem

Berkelium provides over 4.5 Petabytes of raw NVMe/HDD storage managed by Ceph. The primary storage tier exposed to user pods is CephFS, backed by the cephfs-sc StorageClass.

Key Capabilities

ReadWriteMany (RWX): Thousands of distributed worker pods across different compute nodes can read and write to the same volume concurrently.
POSIX Compliant: Supports standard Linux filesystem semantics (open, seek, flock, hard/symlinks).
Snapshot Support: Automatically backed up via Ceph snapshot schedules.
