Home Network and Servers

Most of the networking gear is Ubiquiti and I'm very happy with the integration and ease of setup. Adding several APs to cover my house was about as simple as it gets. There are two 10GbE drops for both my office and my partner's office. The servers are connected directly to the aggregation switch via 10G links as well.

The rack on the left is in my utility room and the rack on the right is in my office.

The HP ProLiant DL380p Gen 8 on the bottom labeled "gila" is set up with a ZFS filesystem with multiple pools for various use cases (Frigate, Samba/NFS, etc). The other one is unpowered and just a spare at this point.

The Symmetricom TrueTime XL-DC-602 is a GPS locked receiver that provides NTP and outputs a 10 MHz reference for synchronizing my test equipment.

Few things that were useful while setting all this up:

ilo-exec.exp

Expect script to execute fan silencing commands on the HP servers through iLO. Without this the servers are obnoxiously loud. I have this running on a schedule from the UDM, quick and dirty but it works perfectly. I needed to add an extra fan for the RAID controllers but haven't seen any issues with things overheating otherwise.

#!/usr/bin/expect -f

set timeout 2
set host [lindex $argv 0]
set level [lindex $argv 1]
set script [split [exec ./silence.sh $level] "\n"]

spawn timeout --verbose 60 \
      ssh -tt Administrator@$host \
      -o KexAlgorithms=diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 \
      -o PubkeyAcceptedAlgorithms=+ssh-rsa \
      -o HostkeyAlgorithms=+ssh-rsa \
      -o StrictHostKeyChecking=no \
      -o ConnectTimeout=$timeout

foreach line $script {
  expect "hpiLO-> "
  send "$line\r"
}

expect "hpiLO-> "
send "exit\r"
expect "CLI session stopped"
expect eof
wait
