The MDTM Project

MDTM Hardware Platform  

MDTM will be deployed in DOE Data Transfer Nodes (DTNs). The DTNs are typically high-end Linux servers and configured specifically for wide area data transfer. A DTN typically has three major components (Figure 1 and 2):

• A NUMA-based system architecture

• A DTN features one or multiple NUMA nodes

• A NUMA node has one or multiple CPU processors

• A CPU processor consists of multiple cores

• One or multiple advanced NICs to access wide area networks

• 10/40 GE NICs

• One or multiple interconnection links for storage access

• Local storage (Raid, SSD)

• Directed connected storage (via Fiber Channel or Infiniband)

• Distributed parallel file systems (via Infiniband, 10/40 GE NICs)

• e.g., Lustre parallel file system

• e.g., GPFS file system
