Find out How to Lower your DPPM

memory for
maximum uptime

Zefr eliminates over 90% of memory reliability failures

Answering the call to workload-driven computing, powerful, High Performance Computing (HPC) platforms are processing massive amounts of data to unlock value.

This trend demands maximum uptime.

Industry Standard
Memory Reliability
isn’t Sufficient

Current Defective Parts per Million (DPPM) simply aren’t low enough, contributing to:

  • Delayed platform bring up
  • Inflated maintenance costs
  • Reduced system yield rate

Defective memory can lead to multiple complications

Operational
  • Errors – ECC slow down of system performance
  • Identifying bad modules
  • Product replacement
  • Debugging
  • System integration
  • Deployment
Administrative
  • Paperwork to begin financial credits
  • RMA & FA – return merchandise authorization
  • Jabil time
  • AWS request
  • Potential manufacturing delay
  • Replacement product shipping
  • Negotiated poor product penalties
Others
  • Damages Reputation

Resulting in downtime costing thousands of $$$

Zefr is a Proven Process with Over 3 Million Memory Modules Shipped

With Zefr Memory, our High Performance Computing System came up fast, completed the acceptance-criteria period flawlessly, and has consistently operated reliably, running mission-critical jobs without disruption.
