Weka's new pod claims 1000PB in a 56U rack using 1,800 Micron 245.76TB SSDs and a decades-old compression trick

WEKA combines NeuralMesh 6 with WEKApod 3, using compression and 1,800 Micron SSDs to claim 1.1 exabytes per rack.

WEKA has launched WEKApod 3, a storage appliance line built specifically to run its new NeuralMesh 6 software at rack-scale density. The flagship Prime Max configuration claims 1.1 exabytes of effective capacity within a single 56U rack, positioning it as the first system to cross that threshold.

Raw capacity versus effective capacity

Using Micron’s 245.76 TB 6600 ION SSDs across roughly 1,800 drives per rack yields only 441.5 PB of raw hardware capacity - well under half an exabyte. That configuration packs 70 NVMe drives into a compact two-rack-unit, two-node chassis for maximum density. The advertised exabyte-scale capacity therefore depends heavily on data reduction technologies rather than installed flash alone.

Software tiering and data reduction

Fingerprinting, similarity hashing, deduplication, and compression run by default across every deployment, with write overhead kept below 5%. WEKA claims up to 6x capacity savings specifically on AI training data, backed by a contractual guarantee covering both reduction ratio and performance.

AlloyFlash tiering automatically routes latency‑sensitive operations to TLC flash while sending bulk‑capacity data to QLC drives, which run roughly 30-40% cheaper per terabyte. Per‑rack throughput reaches 10.2 TB/s with 210 million IOPS - figures WEKA says beat the next‑best publicly available alternative by 114% in throughput density.

NeuralMesh 6 and WEKApod 3 integration

NeuralMesh 6 will hit the shelves in the second half of 2026, with existing customers upgrading at no additional cost. WEKApod Nitro, Prime, and Prime Max are already orderable through WEKA’s distributor network, with deliveries beginning in fall 2026.

Jeremy Werner, senior vice president at Micron’s Core Data Center Business Unit, said the architecture paired with Micron’s 245TB SSDs delivers 15.8 petabytes within a single 2U footprint. Steve McDowell, chief analyst at NAND Research, argued that inference workloads at production scale demand different metrics than training, pointing to tokens per rack and cost per inference as the numbers buyers should now track.

Structural pressures driving the hardware rethink

WEKA points to several structural pressures behind this hardware approach, starting with a documented drop in US data center construction in 2025. Grid connection queues in major markets now stretch four to seven years before new capacity comes online. Morgan Stanley has forecast a 49‑gigawatt power shortfall across the United States extending through 2028, compounding existing NAND supply constraints.

WEKA argues that inefficient storage directly competes with GPUs for the same limited rack space and power budget. By managing its own hardware supply chain instead of relying on third‑party OEM channels, the company says it can offer more predictable pricing and delivery timelines.
