HPE DMF Administration

Код курса  Код: H6LG1S    Заявка  Предварительная запись    Продолжительность  Кол-во часов: 40 , Кол-во дней: 5

This course provides system administrators with the knowledge and skills necessary to configure, maintain, diagnose, and repair simple failures associated with the SGI Hierarchal Storage Management solution called DMF. DMF is a comprehensive data management tool that manages space on native XFS or CXFS file systems in either a monolithic or a distributed cluster configuration using parallel data mover nodes. 

DMF provides the capability to cost-effectively manage storage of large collections of files. DMF accomplishes this by moving file data blocks back and forth between primary storage and low cost secondary storage devices (including tape, disk and cloud storage). File migration and recall can be transparent to the end user according to site policies, or it can be invoked manually via the command line. 

At course completion, students will be able to install and configure hardware and software to create monolithic and distributed environments. Students will configure, modify and utilize their own DMF environment during course labs. This course emphasizes understanding data flow through DMF and interpreting log messages.
