The lease on the Odyssey compute cluster comes to an end this year, and a refresh of the cluster will occur at the end of summer of 2019.
Our new cluster will be provided by Lenovo and utilize their SD650 NeXtScale servers with direct-to-node water-cooling for increased performance, density, ease of expansion, and controlled cooling.
These units contain two nodes per 1U rack space, so this will change the purchasing model for those who wish to have dedicated hardware. Because of the new cooling system, new nodes will only be added at specific times of the year. We will coordinate this with PIs during the purchasing phase for any new hardware.
More details to follow here as well as a timeline for the shutdown and replacement of the Odyssey cluster.
