Port 2463: LSI RAID Management — The Storage Controller's Quiet Window

What This Port Does

Port 2463 is the web server port for LSI Storage Authority (LSA), the management interface for MegaRAID storage controllers. When LSA is installed on a server with a MegaRAID card, it binds to port 2463 and serves a browser-based dashboard for monitoring and configuring the RAID array.

IANA formally assigned port 2463 to the service name lsi-raid-mgmt on July 18, 2014, for both TCP and UDP.¹

Point a browser at http://server-ip:2463 and you get the LSA interface: controller health, drive temperatures, rebuild progress, battery backup status. Everything that determines whether your data survives the next hardware failure.

What MegaRAID Is

MegaRAID controllers are hardware RAID cards made by LSI Logic — now Broadcom after a chain of acquisitions.² They sit inside servers and present multiple physical drives to the operating system as a single logical volume. The controller handles parity calculations, caching, and drive failure recovery in hardware, offloading that work from the CPU.

The controllers are everywhere: Dell PowerEdge servers, HPE ProLiant, custom-built storage arrays. If a server in a data center is doing RAID 5 or RAID 6, there's a reasonable chance a MegaRAID controller is doing the work.

How Port 2463 Got Here

LSI's original management tool was MegaRAID Storage Manager (MSM) — a Java desktop client that administrators installed locally to manage controllers. It worked, but it required installing Java, maintaining a desktop client, and was unpleasant to use remotely.

LSI Storage Authority replaced it with a web-based interface. Instead of launching a desktop application, you open a browser. Port 2463 is the port that web server listens on by default.³

Avago Technologies acquired LSI in 2014 for $6.6 billion.⁴ Avago later acquired Broadcom and took its name. The product lives on under Broadcom, with LSA still serving on port 2463.

What Listens on This Port

If you see traffic on port 2463, it's almost certainly LSI Storage Authority. There are no widely reported malicious uses or unofficial services that claim this port.

To check what's using port 2463 on a Linux system:

# Show what process is listening on port 2463
ss -tlnp | grep 2463

# Or with lsof
lsof -i :2463

On Windows:

netstat -ano | findstr :2463

If something is bound to this port and you don't have a MegaRAID controller, investigate. It shouldn't be there.

Why This Port Matters

RAID controllers fail quietly. A drive dies, the array continues running in degraded mode, and nobody knows until a second drive dies and the data is gone. LSA on port 2463 is the notification system — but only if someone is watching it.

In practice, most teams configure LSA to send email alerts on drive failure, but the web interface on port 2463 is where you go to check rebuild progress, force a drive to fail, or configure hot spares. It's the kind of port that gets forgotten in firewall rules and remembered at 3am.

Registered Port Range

Port 2463 falls in the registered ports range (1024–49151). IANA maintains assignments for this range, but unlike well-known ports (0–1023), processes can bind to registered ports without root or administrator privileges. This range is where application-specific services live — management interfaces, databases, development tools, and proprietary protocols that aren't system-level services but still have a named, consistent home.⁵
