====== RheaSiliva Server Setup ====== //rheasilvia// is the dedicated backup storage server of the OICE. Currently (February 2016) it is still located at the OICE, but the future preferred location in case of a catastrophic event is the server rooms of the RRZE (Regionales Rechenzentrum Erlangen). ===== Summary ===== | IP address | 192.168.231.216 | | FQDN | rheasilvia.oice.uni-erlangen.de | | Location | OICE, Room 071.13 00 049 | | Chassis | 19" 2 HU Rack Mountable | | CPU | Intel Xeon CPU E5-2620 @ 2.4 GHz | | RAM | 8 GiB | | SSDs | 2x 500 GB in RAID 1 | | HDDs | 6x 8 TB in RAID 6 | | OS | Ubuntu 14.04.4 LTS (GNU/Linux) | ===== Description ===== //rheasilvia// features basic Ubuntu LTS 14.04.4 server setup which only allows for SSH access of a dedicated backup user "backup" and administrators. The SSDs are used to mount the root directory ''/'' while the large RAID 6 array, which currently supplies 29 TiB of space, is mounted (mirroring //romulus//) at ''/srv''. Backups are transferred from //romulus// via encrypted SSH connections over port 20 using the backup user. Currently, this is done by both the rsync backups and the Duplicity backups. All backups end up in subdirectories of ''/srv/backups''.
