Apple's Xsan remains a powerful, enterprise-grade Clustered File System (CFS) for macOS, built on the StorNext platform. As data demands grow, particularly in media and entertainment, understanding how to scale Xsan without compromising performance is critical. 1. Vertical vs. Horizontal Scaling
: Organize LUNs into pools (e.g., a "Fast" SSD pool and a "Capacity" HDD pool) to manage data placement based on performance needs. scaling xsan
| Component | Limitation | |-----------|-------------| | Metadata Controllers | 2 nodes max (no true active‑active multi‑MDC beyond 2) | | LUN count per volume | ~256 before performance degrades | | Mixed performance | No automatic load balancing across affinities | | Client OS | Modern macOS drops XSAN client (no Mac client in macOS Ventura+); use Windows/Linux clients or older macOS. | Vertical vs
