Dell HPC Lustre Storage solution with Intel Omni-Path

5.3 Misc. tunings

NOTE: Setup of the Intel Omni-Path HFI interconnect will utilize IPoIB and the ifcfg-ib0

configuration file. Consult the Dell HPC Lustre Solution Configuration Guide for details.

Verify that the MTU setting in the IPoIB interface configuration file is set at 65520.

[root@ieel3-oss1 ~]# cat /etc/sysconfig/network-scripts/ifcfg-ib0

DEVICE=ib0

BOOTPROTO=static

ONBOOT=yes

NM_CONTROLLED=no

CONNECTED_MODE=yes

MTU=65520

5. Conclusions

There is a well-known requirement for scalable, high-performance clustered file system solutions. The

Dell HPC Lustre Storage with Intel EE for Lustre addresses this need with a well-designed solution that

is easy to manage and fully supported. The solution includes the added benefit of the Dell PowerEdge™

generation server platform, PowerVault™ storage products and Lustre

technology, the leading

open source solution for a parallel file system. The Intel Manager for Lustre (IML) unifies the

management of the Lustre File System and solution components into a single control and monitoring

panel for ease of use.

The scale of the raw storage, 960TB per Object Storage Server Pair and up to 14.9GB/s of write and

16.8GB/s of read throughput in a packaged component, is consistent with the needs of the high

performance computing environments. The Dell HPC Lustre Storage solution is also capable of scaling in

throughput as easily as it scales in capacity.

The continued use of generally available, industry-standard benchmark tools like IOzone and MDtest

provide an easy way to match current and expected growth with the performance outlined. The

profiles reported from each of these tools provide sufficient information to align the configuration of

the Dell Storage for HPC with Intel EE for Lustre Solution with the requirements of many applications or

group of applications.

The Dell HPC Lustre Storage solution delivers all the benefits of a scale-out parallel file system-based

storage for your high performance computing needs.
