- Currently only 3 nodes are provided, a fourth node is currently a work in progress at the UVT in Romania
- Each machine has two drives:
- 1 x 50 GB drive with Ubuntu installed. The drive is /dev/vda
- 1 small /boot partition
- 1 LVM PV partition spanning the rest of the disk
- The Root LVM Logical Volume is of ~16GB and can be resized with
23 more GB. If you need help with this please contact me.
- 1 x 116 GB drive empty. The drive is /dev/vdb
- There are two networks available:
- eth0: DHCP Assigned private address. Used for internet access or
whatever you want. The connectivity is *1Gbps*.
- eth1: Static Assigned address. Usable by you for whatever you want.
You can change the addresses assigned by us to whatever you want on this
interface. The connectivity is *~10Gbps*. We have capacity for up to
40Gbps but there are some limitations in our current Infiniband
setup that
caused some security concerns, including this setup delay. For now the
10Gbps is run as Ethernet over IP (more exactly vxlan inside an
OpenVSwitch
fabric).
