Oracle ZFS Storage ZS11‑2 for PCA X11

Oracle ZFS Storage ZS11‑2 (PCA X11 Storage Sub‑System)Oracle ZFS Storage ZS11‑2 forms the high‑availability shared storage foundation inside the Oracle Private Cloud Appliance X11 engineered system. The solution consists of two 2‑rack‑unit ZS11‑2 storage controllers configured in an active‑passive HA cluster to eliminate single‑points‑of‑failure. It connects to one or multiple DE3‑24 disk expansion enclosures for scalable raw storage capacity. Leveraging Oracle Hybrid Storage Pool technology, the ZS11‑2 dynamically manages DRAM memory, flash cache devices and backend HDD/SSD storage tiers to optimise I/O performance for the VM workloads running on PCA X11 compute nodesOracle. Inside the PCA X11 rack, the ZS11‑2 controllers integrate into the 100 Gb RoCE internal data fabric, delivering high‑performance block storage volumes consumed by tenant virtual machines. It provides native storage‑oriented data services including snapshots, clones and thin‑provisioning for PCA virtual disks. Storage capacity is horizontally expandable by deploying extra DE3‑24 disk shelves within the PCA rack. Firmware interoperability is critical: ZFS Storage Appliance OS must be maintained in sync with PCA appliance software release 3.0.2 or newer. This dedicated ZS11‑2 storage cannot be removed and repurposed as a standalone general‑purpose ZFS storage appliance outside the PCA X11 rack environment.
