11 Dell HPC System for Manufacturing—System Architecture and Application Performance
2.7 Dell IEEL Storage
Dell IEEL storage is an Intel Enterprise Edition for Lustre (IEEL) based storage solution consisting of a
management station, Lustre metadata servers, Lustre object storage servers, and the associated backend
storage. The management station provides end-to-end management and monitoring for the entire Lustre
storage system.
The Dell IEEL storage solution provides a parallel file system with options of 480 TB or 960 TB raw storage
disk space. This solution is typically used for scratch space for larger clusters.

2.8 System Networks
Most Dell HPC Systems for Manufacturing are configured with two networks—an administration network
and a high-speed/low-latency switched fabric.
The administration network is Gigabit Ethernet that connects to the onboard LOM/NDC of every server in
the cluster. This network is used for provisioning, management and administration. On the EBB, IBB,
IGPGPUBB and VDI servers, this network will also be used for IPMI hardware management. For
infrastructure and storage servers, the iDRAC Enterprise ports may be connected to this network for OOB
server management. The heartbeat ports for NSS-HA and IEEL Gigabit management ports may also be
connected to this network.
Each rack in the system contains at least one Dell Networking S3048-ON Ethernet switch. If there is more
than one switch in the system, multiple switches will be stacked with 10 Gigabit Ethernet stacking cables.
A high-speed/low-latency fabric is recommended for clusters with more than four servers. The current
recommendation is an EDR InfiniBand fabric. The fabric will typically be assembled by using Mellanox
