The National Computing Infrastructure’s 180,000-core, nine-teraflop Gadi supercomputer is adding petabytes of new storage this year, as part of a deal signed with UK vendor SoftIron.

The initial 12.5 PB of object storage will serve as an Openstack cloud framework and serve as active project storage for projects using the system.

The facility will leverage four distinct storage classes: high-performance computing (HPC) storage, a facility-scale high-performance persistent storage platform, a cloud-focused object store, and managed hierarchical storage (HSM) large-scale based on archive storage system.

SoftIron’s HyperDrive storage appliances will be backed by the open source Ceph storage framework.

Explaining what prompted the need for new storage, an NCI spokesperson said iTnews“We are increasingly seeing the growth of edge computing with pre- and post-processing requirements being carried out as part of our cloud facility in support of the ‘big iron’.

“This equipment will complement our existing storage options and sit between our fast Luster parallel file systems and our archival storage tier.

“This will help complete the ecosystem of storage services for our researchers.”

The NCI spokesperson could not provide an installation time frame for iTnewssaying, “We currently only have the proof-of-concept equipment in place and are awaiting delivery of the primary equipment purchase.

“Production availability is subject to supply chain delays.”

The Gadi supercomputer entered service in November 2019 and replaced its predecessor, Raijin, in January 2020.

Gadi has already gone from the 3200 knots he had in January 2020 to over 4000 knots. At launch, it had 8PB of operational disk storage.

NCI Associate Director of Cloud Services Andrew Howard said NCI chose Ceph “for its maturity and robust capability as a unified, distributed storage system for emerging and non-traditional HPC capabilities.”

Howard said Ceph offers “flexibility in its ability to offer object, block, and file storage protocols in a single storage cluster, with the ability to scale virtually infinitely, based on demand. “.
