The "DS3615xs" designation is crucial. The actual Synology DS3615xs unit utilizes an Intel processor (specifically the Intel Atom C2538). This is significant because it uses the x86_64 architecture.

Let me know – I can point you to the right approach (including migration to newer DSM without losing data, if possible).

This grants the DIY server access to all the advanced features of Synology’s high-end rackmount units, including:

In the world of Network Attached Storage (NAS), Synology is widely regarded as the gold standard. Their hardware is robust, but it is their operating system—DiskStation Manager (DSM)—that truly sets them apart. For many technology enthusiasts and IT professionals, the high cost of Synology hardware has led to a thriving subculture of "Xpenology"—the practice of installing Synology’s DSM on non-Synology, third-party hardware.

Technically, a .pat file is a compressed archive (similar to a .tar or .zip file) that contains the Linux kernel, system binaries, configuration files, and scripts required to install or update the operating system on specific hardware. Synology maintains different .pat files for different hardware architectures (ARM v7, ARM v8, Intel x86, etc.).
