I’ll be using this additional computer server as a Ceph MDS hot standby server, which basically means I can access a Ceph
filesystem even if the primary MDS server that I have (on a 10 GbE network) has a problem. In addition, I’ve added a 4
TB SSD that I can use for backups and similar purposes.
In comparison to some other small computers like the Intel NUC, which can be outfitted with (for example) 64GB
RAM, 2.5GB LAN, and a faster processor, the combination shown below presents a good value for being just 8GB RAM,
and 1GB LAN.
There are just three items to order. The computer case, the Single Board Computer (SBC), and the additional M.2 NVME
storage.
re_computer case: Most Compatible Enclosure for popular SBCs including ODYSSEY - X86J4105, Raspberry Pi, BeagleBone and Jetson Nano/Xavier NX
ODYSSEY - X86J4125864 v2 - with 64GB eMMC, Linux and RP2040 Core
Crucial P3 4TB PCIe 3.0 3D NAND NVMe M.2 SSD, up to 3500MB/s - CT4000P3SSD8
Here are more details on the 4TB SSD:
Form Factor: M.2 2280 Capacity: 4TB Memory Components: 3D NAND Option: P3
You’ll need a USB thumb drive to install Ubuntu 22.04.2 LTS, or another OS of your choice.
Press F7 on the keyboard for the boot options.
On my system I had about 3.87 TB of usable storage, using an XFS filesystem.
