Compute gets the headlines. Data movement decides whether your GPUs ever run. For more than a decade Zettar has done one thing with uncommon focus — get massive data where it needs to be, fast and fully verified. We took that work from a U.S. DOE world record to a turnkey appliance — every hardware component selected, matched, and pretuned to our zx data mover — so you get record-setting throughput the day it's racked.
Zettar was founded in 2008 by Dr. Chin Fang (CEO), with roots at Stanford and SLAC. Since 2014 the focus has never wavered: solve the problem most tools ignore until it stalls everything — moving enormous volumes of data fast enough to keep data-intensive science and infrastructure running.
Since 2015 we've been engaged on SLAC's LCLS-II, a U.S. DOE exascale-class instrument that demanded throughput far beyond what conventional tools could deliver. With SLAC and ESnet, in 2018 our software data mover set the record — 1 PB in 29 hours at 96% link utilization over a 5,000-mile loop, encrypted and checksummed end to end. Zettar also won the Supercomputing Asia 2019 Data Mover Challenge, and we kept proving it in public: SC21 with DDN and NVIDIA, SC22 on the NVIDIA DPU, an AIC/Intel appliance at SC23, and SC24 on the NVIDIA DPU again, with MiTAC's participation.
As the AI era turned data movement into the bottleneck, we packaged everything we'd proven into the turnkey zx Appliance — with the hardware selected, matched, and pretuned to zx as one engineered system. Its proven core platform is the HPE ProLiant DL380 Gen 11. It uses Linux as the OS and moves data roughly 10× faster than typical commercial or freeware movers. We don't sell AI. We move the data that powers it.
Compute, storage, and network are treated as first-class infrastructure. Moving data between them should be too. When it isn't, GPUs idle and pipelines stall — so we engineer the data-movement layer with the same seriousness as the rest of the stack.
Wire-speed transfer shouldn't be a science project. Rather than hand you knobs to turn across firewalls and mismatched hardware, we co-design hardware and software into one validated appliance — so you get the result, not the homework.
Every claim we make is backed by a number you can check. A petabyte in 29 hours. 96% link utilization. A challenge win against the field. Reproducible results at national-lab scale — not marketing math.
