Scale up your storage, Simplified.

An all flash NVMe-oF enclosure with no CPU, DRAM, or software to buy. Capacity never waits on the memory market.

All the flash, none of the scarcity.

Dense NVMe-oF flash on standard Ethernet, with no CPU, DRAM, or software to buy.

Headless, Nothing Scarce Inside.

Just NVMe SSDs and BoostX target cards: no x86 CPU, no DRAM, no software. As AI drives those prices up, capacity never waits on the supply chain.

PB Scale in a Single 2U.

122.88 TB QLC today, 245.76 TB on the roadmap, about 3.19 PB per 2U. Read heavy inference suits QLC, and tight rack power rewards density.

Highly available.

Redundant by design, so no single failure takes the pool offline. It all runs on the RoCEv2 Ethernet you already operate, no proprietary switch or fabric to buy.

Headless JBOF.

Traditional arrays burn an x86 CPU, DRAM, and software before the first drive. KESAR-E puts that on the BoostX™ NRT card, which serves the SSDs straight over Ethernet.

Same NVMe-oF target role, with the budget going into flash instead of CPU, DRAM, and software.

More bandwidth in every rack unit.

Throughput per rack unit, about 200 GB/s per 2U, roughly 1.55× a comparable enclosure.

High availability, from client to flash.

Hosts reach the enclosure over redundant Ethernet paths with NVMe multipath (ANA), and two canisters share one set of dual port SSDs. A failed NIC, link, switch, or canister fails over with no disruption.
