Node and Storage Investments

Overview


Investment criteria and standard node configurations are reviewed annually at the beginning of each fiscal year by OIT. This page has been updated for FY21.

Investors may purchase compute nodes on the cluster that will belong to their private condo. These nodes are exclusive to investors and the project(s) to which they belong and can participate in the responsible node sharing program. If you wish to purchase nodes for your use on the cluster, please submit a ticket to help@acf.utk.edu. A staff member will contact you to discuss details regarding the purchase and develop a service level agreement (SLA) that will apply to the node(s). For FY21, the standard SLA period for a compute or GPU node investment will be three years. Other periods will be considered on a case-by-case basis.

Note that costs below are estimates and final costs will be determined based on equipment configuration and funding source. Research R accounts can only be charged the direct equipment cost since the ACF is not a cost center.

Standard Compute Node


With the standard compute node, investors will obtain a powerful compute node that can handle significant high-performance workloads. The pertinent technical specifications are listed below.

The estimated cost for a standard compute node is approximately $10,000. Modifications can be made to this configuration on a case-by-case basis.

Standard GPU Node


With the standard GPU node, investors will obtain a compute node that can handle standard HPC workloads and has significant GPU performance for GPU-intensive applications. The pertinent technical specifications are listed below.

The estimated cost for a single standard GPU node is approximately $23,000.00. Modifications can be made to this configuration on a case-by-case basis.

Storage Investments


Investors can purchase dedicated high-performance Lustre storage for their projects. At the time of this writing, the cost per terabyte is $42 per year. Be aware that institutional projects receive 1TB of Lustre project space free of charge; however, any storage beyond that amount should be purchased.

Please note that the cost per terabyte listed previously only includes the storage equipment, administration, and maintenance of the file system and does not include backups. Backups and archives of Lustre storage are the responsibility of the end users. On a case-by-case basis arrangements can be made for limited amounts of backups or archive and should be discussed and included into any SLA. For more information on the cluster's file systems, please refer to the File Systems document.
