Compare · Zettar vs Globus

The Globus alternative for AI and petascale.

Globus is a familiar way to orchestrate and share research data across institutions. But it is grid-era: it manages transfers over GridFTP and still depends on your DTNs being well-tuned — so at AI and petabyte scale it leaves fast links badly underused. Zettar co-designs the whole data path to hit line rate, turnkey.

The problem

Orchestration is not the same as line rate.

Globus schedules and manages the transfer, but the speed you actually get still comes down to your endpoints — the data-transfer nodes, storage, and tuning underneath. Its grid-era design was built for moderate research flows, not for feeding GPU clusters or moving petabytes on deadline, so a fast link routinely runs at a fraction of its capacity. Making it fast becomes your tuning project, on top of the service.

Globus is good at moving and sharing research data between institutions. When the goal is line rate at AI and petabyte scale — with nothing to tune — that is what the co-designed appliance is for.

Why Zettar

Co-designed for line rate, not just orchestration.

The Zettar zx Appliance co-engineers storage, host, network, and software with an NVMe burst buffer to run at line rate — roughly 10× typical movers, with no software ceiling — and ships pretuned on the hardware you choose. With SLAC and the U.S. DOE it moved 1 PB in 29 hours at 96% link utilization over a 5,000-mile path, and it is in production at Taiwan’s NCHC. Winner of the Supercomputing Asia 2019 Data Mover Challenge.

FAQ

Common questions

FAQ

Is Zettar a replacement for Globus?

For high-speed movement at AI and petabyte scale, yes. Globus is good at orchestrating and sharing research data, but it is grid-era and its speed depends on your DTNs being well-tuned. The zx Appliance co-designs the whole path and ships pretuned to run at line rate.

FAQ

Does Globus not already move data fast?

Globus manages the transfer; the throughput still comes from your endpoints and tuning underneath, so at AI scale a fast link routinely runs at a fraction of capacity. zx is co-designed across storage, host, network, and software to reach about 90%+ line rate, proven at 1 PB in 29 hours.

FAQ

Can Zettar work with our existing research setup?

Yes. It is platform-neutral and runs on the enterprise hardware you choose, on-premises and in-country, moving file, object, and streaming data. Many research and HPC sites run it alongside existing tools.
