Figure 2: Dell Storage for HPC with Intel EE for Lustre Components Overview
A new feature in this release includes an option to utilize the Lustre Distributed Metadata. This feature
referred to as DNE, will provide the ability to scale metadata performance and the capacity to further
enhance the solution. The feature will allow the distribution of your metadata (both file and directory)
across multiple Metadata Targets (MDT), and enable scaling of the size of the namespace as well as the
metadata throughput.. The Lustre DNE feature will be split intotwo separate phases of development
and release. Phase 1, Remote Directories, will enable administrators to set up and distribute Lustre
sub-directories on a defined MDT . Phase 2, Striped Directories, will enable administrators to distribute
the contents of a given directory across multiple MDTs. At the time of this writing, Phase 1 has been
released and is supported by Intel Enterprise Edition for Lustre v.2.3 software. Phase 2 is in active
development and slated for a future release with support. This document will cover Lustre DNE
implementation Phase 1. Figure 3 below provides a visual representation of the solution architecture
with the Lustre DNE option.
