| + | ===== System Specification ===== | ||
| + | |||
| + | ==== Hardware ==== | ||
| + | |||
| + | Nerdserv runs on a Super Micro board called a2sdi-16c-hln4f. This board has a Intel Atom Processor C3955 with 16 Cores. | ||
| + | The board is equipped with 128GB of ECC RDIMM RAM, which can be extended to 256GB of RAM, if two RAM Modules (RDIMM ECC DDR4 2400 64GB) are bought and added | ||
| + | |||
| + | The OS is on two SSDs that are in a RAID1 configuration. This is exclusivly for the Hypervisor. | ||
| + | |||
| + | VMs get their disk space from a M.2 NVME Disk that has 2TB capacity. | ||
| + | |||
| + | ==== Software ==== | ||
| + | |||
| + | As Hypervisor, Proxmox is used. | ||
| + | |||
| + | ==== Storage ==== | ||
| + | |||
| + | If you require signifcant amounts of storage ("more then a couple of GB"), please use the MFS as (mounted) storage | ||
| + | |||
| + | ==== Backups ==== | ||
| + | |||
| + | Maybe a snapshot from your VM is regularly created and saved on the MFS. Do not rely on this. | ||
