Current status

Smerdon told The Register on Nov. 11, 2026 that 145 systems are deployed and estimated about $5 million of avoided DRAM cost. His PrimeTime figures were 95 percent at half DRAM and 80 percent at one-quarter DRAM. The October 2026 white paper reports about 87 percent on a different 1.5 TB to 768 GB PrimeTime test dated Oct. 1, 2025. License sales are a later phase, and HPE is named only as an OEM in the first readiness phase.
