2.5 Dell EMC IEEL Storage
Dell EMC 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 EMC 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.

2.6 System Networks
Most HPC systems are configured with two networks—an administration network and a high-speed/low-
latency switched fabric. The administration network is typically 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 and IBB 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 Ethernet management ports may also be
connected to this network. The management network typically uses the 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 using Mellanox SB7890
36-port EDR InfiniBand switches. The number of switches required depends on the size of the cluster and the
blocking ratio of the fabric.
