What This Port Is
Port 60284 falls in the dynamic/ephemeral port range (49152–65535). This range is set aside by IANA for temporary use, private services, and automatic port allocation. No service can be formally registered here. The Internet assumes these ports are yours to use, for now, for this connection, then they're gone.
Port 60284 specifically is claimed by Xsan, Apple's storage area network (SAN) filesystem.1 It's one of several ports in this range that Xsan uses for communication between Mac workstations and shared block storage systems.
What Xsan Was
Xsan was launched in 2004 as Apple's answer to enterprise storage networking. It allowed multiple Mac desktops and Xserve servers to access the same block storage over Fibre Channel networks, creating a shared filesystem similar to what larger enterprises used for video editing, 3D rendering, and other I/O-intensive work.2
The architecture was real infrastructure: Fibre Channel switches, SAN controllers, storage arrays. It worked. But it was also expensive, specialized, and required dedicated networking hardware that most organizations didn't want to maintain.
Why Port 60284 Matters (Barely)
If you see port 60284 listening on a Mac, something in the Xsan ecosystem is running. That could mean:
- A Xsan client trying to connect to a metadata controller
- A connection to shared block storage
- An old system that hasn't been updated since the Xsan era
But honestly: most organizations moved to simpler solutions. NFS. Samba. Cloud storage. Xsan was technically sophisticated but organizationally heavy.
How to Check What's Using It
On macOS, find what's listening on this port:
On Linux:
On Windows:
If nothing shows up, the port is idle. That's the most common answer for port 60284 in 2026.
The Ephemeral Port Range and Why It Matters
The range 49152–65535 exists because the Internet needs somewhere to put temporary connections. When your browser makes a request to port 443, your operating system assigns a random port from this range to the other end of the connection. Those ports live for seconds, then vanish.
Because this range is unregistered, applications can claim ports within it for private use. Apple did with Xsan. Someone else might do it on your network. The operating system will also use this range automatically for outbound connections.
That's the tension in the ephemeral range: it's simultaneously reserved for nobody and available to anybody.

- Port 60274 — Xsan Filesystem Access
- Port 60767 — Xsan Filesystem Access
- Port 63482 — Xsan Filesystem Access
- Port 65056 — Xsan Filesystem Access
These all serve the same function: temporary connections in an infrastructure most organizations have moved away from.
