Kiesanowski and Kerdemelidis wedding trip
|
I now run a Raspberry Pi4 in my woodshed. Its prime purpose is to run BackupPC and backup all my stuff that is in the house. If I ran the backup system inside the same building, it wouldn't be very protective in the event of a fire etc. There's a 5TB USB3 harddrive attached to the Pi4, and a Pi PoE Hat for power. Additionally, I use a U-BLOX 8 GPS to contribute data to the Galmon project https://galmon.eu/ Why? Running Mains power to the shed would have cost a lot of money. Whereas I can wire cat6 UTP without any licence or qualifications. This gives me ~15 watts per port, which was more than enough to run the Pi and a HDD. The whole thing uses around 6.3 watts according to the Juniper 2300 switch. root@sw03-poe> show poe interface ge-0/0/6 PoE interface status: PoE interface : ge-0/0/6 Administrative status : Enabled Operational status : ON Power limit on the interface : 15.4W Priority : Low Power consumed : 6.3W Class of power device : 3 PoE Mode : 802.3at root@woodshed:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT sda 8:0 0 4.6T 0 disk `-VG--PI1-backuppcpi 254:0 0 1.6T 0 lvm /var/lib/backuppc mmcblk0 179:0 0 14.5G 0 disk |-mmcblk0p1 179:1 0 256M 0 part /boot `-mmcblk0p2 179:2 0 14.3G 0 part / root@woodshed:~# hdparm -t /dev/sda /dev/mmcblk0 /dev/sda: Timing buffered disk reads: 376 MB in 3.00 seconds = 125.16 MB/sec /dev/mmcblk0: Timing buffered disk reads: 124 MB in 3.01 seconds = 41.19 MB/sec
