MSCP-Hub
An MSCP disk server for OpenVMS nodes, running on Linux.
| Version | X01-24ECO2 (tag) |
|---|---|
| Status | Active development |
| Platforms | Linux, kernel 5.10+ (io_uring); Raspberry Pi, NaPi-C |
| Licence | GNU GPL v3 |
| For whom | Owners of a home or teaching VMScluster who want to keep OpenVMS disks on modern media. |
What it is
MSCP-Hub lets OpenVMS nodes on one LAN use Linux files and block devices as their own disks. To OpenVMS it is an HSC-style disk controller speaking NISCA (PEDRIVER); the server is not a cluster member.
Up to 8 disks per server (files or block devices, 512 or 4096 byte sectors), READ, WRITE, ERASE and COMPARE, io_uring with fdatasync before a WRITE is answered, a systemd unit, counters in MHMON, T4 and Modbus/TCP. The server is about 300 KB.
Why
The VMScluster heritage and the engineering culture of DEC are worth keeping: the project is small, every decision in it is written down, it serves as a course for students; the messages, HELP and documentation are done the DEC way.
