Cheyenne returned to service

The Cheyenne cluster was released to users at approximately 5:30 p.m. on Thursday.

CISL staff and HPE engineers identified several issues that are believed to have caused the system’s instability and they replaced problematic hardware components. The system was tested extensively before it was released and as of this morning is meeting or exceeding established performance metrics.

CISL again thanks you for your patience throughout this downtime.
