Tiny servers can make 2.5Gbps network upgrades awkward
An HP Mini 705 G5 was being upgraded with a second for a Proxmox cluster. The goal was to test Ceph by giving the small servers a faster extra network link.
The machine has a second M.2 E-key slot normally used for a wireless card, and the adapter itself barely fits. The problem appears when the cable is attached, because there is not enough room inside the case for the wire path.
Possible fixes include soldering on upright , cutting a hole in the metal case, or buying a different M.2 adapter with another layout. One Dollatek adapter on Amazon had reviews saying it worked with Proxmox, but there are few 2.5Gbps choices there, with more possible options on .
Key points
- The upgrade targets an HP Mini 705 G5, not a Mac mini.
- A second is wanted for a Proxmox cluster.
- The adapter fits in the M.2 E-key slot, but the cable does not have enough room.
- Possible fixes are soldering, cutting the case, or finding a different design.
- Small server upgrades need a physical fit check before buying parts.
