Close up of the cluster hardware
We have room for twice as many nodes in the cluster; available space we plan to fill in the next year.

10 Dell PowerEdger R730 each with two Intel Xeon E5-2699 18 core CPUs. Each has Intel X710 Quad Port 10Gb DA/SFP+ Ethernet.
9 of these have 16 16GB RDIMM, 2133MT/s (256GB RAM) and 8 4TB 7.2K RPM SATA HDD (32TB).
One of these has 16 32GB RDIMM, 2133MT/s (512GB RAM) and 4 4TB 7.2K RPM SATA HDD (16TB).
Data storage
Our online collections are stored in an EMC Isilon storage cluster with a capacity of 1.6PB and EMC VNX with a capacity of 200TB.
We also store data on tape collections that is handled by two tape robots.
