Dell HPC Lustre Storage solution with Mellanox Infiniband EDR
interface using IPoIB (i.e. ifcfg-ib0) as well as your 10GbE Ethernet interface (i.e. eth0) on your OSS
servers to both participate in the Lustre Network.
In the Infiniband EDR fabric, fast transfer speeds with low latency can be achieved. LNet leverages the
RDMA capabilities of the InfiniBand fabric to provide faster I/O transport and lower latency compared
to typical networking protocols.
3.6 Managing the Dell HPC Lustre Storage with Intel EE for Lustre
The Intel Manager for Lustre (IML) takes the complexity out of administering a Lustre file system by
providing a centralized web GUI for management purposes. For example, IML can be used as a tool to
standardize the following actions: initiating failover of the file system from one node to another (for
either OSS or MDS), formatting the file system, issue mount and unmounts of the targets and
monitoring performance of the Lustre file system and the status of its components. Figure 9 illustrates
a few of the IML monitoring interfaces.
IML is a web-based management console to manage the solution (assuming all security requirements
are satisfied). It provides a view of the hardware, software and file system components, while allowing
monitoring and management.
Using IML, many tasks that once required complex CLI instructions can now be completed easily with a
few mouse clicks. IML can be used to shut down a file system, initiate a failover from one MDS to
another, monitor, and so forth.
