Collective
The Borg
We are the Borg. Lower your shields and surrender your ships. We will add your biological and technological distinctiveness to our own. Your culture will adapt to service us. Resistance is futile.
The hackspace infrastructure is now run on small Borg collective of 3 HP Borg ProLiant MicroServer N40L, it start as just one server collective but we have since add to more identical machine to the group.
All three have identical base spec but Queen has two extra 2Tb HDD's
Spec
- AMD Turion II Neo N40L 1.5GHz Dual-Core CPU
- 2x2GB DDR3 ECC UDIMM (8gb max)
- Internal SATA Cold Plug SATA 250GB Hard-Drive
- Embedded RAID 0/1
- 1x Gigabit Ethernet
- 150W PSU
- 1 x HP NC360T dual port gigabit network card
Interconnection
Each cube is fitted with a HP NC360T dual port gigabit network card. These extra ports are used to create direct network links to the other cubes in the collective
HDD replication
The direct link between Unimatrix and Locutus is used to do block level HDD replication and keeps this traffic off out main networks
Unimatrix and Locutus each have two 75GB partitions for the VM storage. There primary store and there opposites backup store.
The primary store is mounted read write and holds the VMs that cube runs.
- Unimatrix
[20GB Host OS][75GB Primary][75GB Locutus replication]
- Locutus
[20GB Host OS][75GB Primary][75gb Unimatrix replication]
Backups
Queen handles the backups for the collective cubes, using the direct connections to Unimatrix and Locutus to keep the backup traffic off the main network. It's 2TB HDD are configure in a software RAID 1 array and using the following LVM partition layout
[100GB DB Backups][1TB VM Backups][Free space]
Database Cluster
Each cube in the collective is part of our SQL database cluster we use mariadb and galera.
VM's running on a host connect directly to the host node of the cluster.
Unimatrix
Unimatrix is a HP Borg ProLiant MicroServer N40L
Original destined to be a direct replacement for Holly but was setup with VMware ESXi giving us the option to run multiple VM's
As an ESXi host Unimatrix (then called Collective) ran all the hackspace VM but until September 2016 when the addition of the two new cubes all the VM where migrated to KVM
Unimatrix is now installed with Debian Jessie and KVM
The the following VM's are hosted
Locutus
Installed with Debian Jessie and KVM
The the following VM's are hosted
Queen
Installed with Debian Jessie and KVM
Queen does not currently host any VM but looks after the database and VM backups for the collective
