Dell Storage for HPC with Intel Enterprise Edition 2.3 for Lustre sofware
Figure 9: OSS Scalability
Scaling the Dell Storage for HPC with Intel EE for Lustre can be achieved by adding additional OSS pairs
with storage backend, demonstrated in Figure 9. This will increase both the total network throughput
as well as the storage capacity at once. This allows for an increase in the volume of storage available
while maintaining a consistent maximum network throughput.
3.5 Networking
3.5.1 Management Network
The private management network provides a communication infrastructure for Lustre and Lustre HA
functionality as well as storage configuration, monitoring and maintenance. This network creates the
segmentation required to facilitate day-to-day operations and to limit the scope of troubleshooting and
maintenance. The management server uses this network to interact with the different solution
components to query and collect systems health information, as well as to perform any management
changes initiated by administrators. Both OSS and MDS servers interact with the management server to
provide health information, performance data, and to interact during management operations. The
PowerVault MD3420 and MD3460 controllers are accessed via the out-of-band (ethernet ports) to
monitor storage array health, and to perform management actions on the storage backend.
This level of integration allows even an inexperienced operator to efficiently and effortlessly monitor
and administer the solution. The default information is summarized for quick inspection, but users can
zoom in to a level of detail of messages from server or storage components.
3.5.2 Data Network
The Lustre file system is served via a Lustre Network (LNet) implementation on either InfiniBand FDR,
ethernet or both. This is the network used by the clients to access data. The Intel Manager for Lustre
