 +
 +DKRZ hosts the Mistral supercomputer which is tightly coupled with two Lustre file systems.
 +We have some small compute and supporting infrastructure that may access the storage of Mistral and a large HPSS system.
 +
 +
 +
 +===== Description =====
 +
 +The DKRZ system was procured in two phases that are roughly have the same size.
 +The storage of the first phase consisted of [[http://www.seagate.com/www-content/product-content/xyratex-branded/clustered-file-systems/en-us/docs/clusterstor-cs9000-datasheet.pdf|ClusterStor 9000]] storage devices and the second phase of [[http://www.seagate.com/files/www-content/product-content/xyratex-branded/clustered-file-systems/_shared/datasheets/seagate-clusterStor-l300-datasheet-11-06-15.pdf|ClusterStor L300]] equipped with Seagate Enterprise Capacity V5 disks (8 TB, ST8000NM0095).
 +
 +Initially, we planned of creating one big shared file system, but now are using two file systems (one for the storage of phase 1 and one for phase 2). Both file systems are mounted on all compute nodes.
