Frequently Asked Questions

What is PRASA's HashTank and how does it benefit blockchain applications?

PRASA’s HashTank is a turnkey, containerized data center equipped with PRASA’s micro-modular immersion cooling technology. It’s specifically designed for blockchain applications like cryptocurrency mining, offering superior cooling performance and ease of deployment compared to traditional data centers. By submerging servers in a non-conductive liquid, HashTank provides:

  • Increased Efficiency: Higher density deployments, leading to more coins mined per space and potentially higher profitability.
  • Enhanced Performance: Consistent cooling eliminates overheating, optimizing network uptime and transaction speeds.
  • Reduced Operating Costs: Efficient cooling translates to lower power consumption, minimizing electricity bills, a major expense for blockchain operations.
  • Improved Stability and Reliability: Consistent liquid cooling environment minimizes hardware failures and ensures reliable blockchain operations.
  • Simplified Infrastructure: Containerized setup and pre-configured liquid cooling eliminate complex air cooling systems and reduce maintenance needs.

Is PRASA's HashTank mobile and flexible?

Absolutely!

HashTank comes housed in ISO shipping containers, making it mobile and easily deployable in any location. Additionally, its micro-modular design allows for flexible scaling based on your operational needs, adding or removing server modules as your blockchain activity evolves.

What are the potential considerations when adopting PRASA's HashTank?

  • Initial Investment: Implementing HashTank may involve a higher upfront cost compared to basic air cooling setups. However, the long-term cost savings from increased efficiency, reduced operating expenses, and potentially higher profitability can outweigh the initial investment.
  • Hardware compatibility: Not all server models are currently compatible with immersion cooling, so ensure your equipment is suitable before switching to HashTank.
  • Maintenance requirements: While simpler than air cooling systems, HashTank setups still require proper maintenance and leak detection procedures. PRASA offers comprehensive maintenance support.

How can PRASA's HashTank help me achieve my sustainability goals?

Beyond increasing efficiency and profitability, HashTank offers several sustainability benefits:

    • Reduced Energy Consumption: The efficient cooling translates to lower power consumption, reducing your carbon footprint and aligning with environmentally conscious blockchain practices.
    • Extended hardware lifespan: The optimal operating temperatures within the liquid environment can extend the life of your servers, reducing e-waste generation and promoting sustainable resource utilization.
    • Minimal Water Usage: Compared to traditional data centers with chillers and water towers, HashTank requires minimal water for equipment maintenance, minimizing your overall water footprint.

Does PRASA offer additional services beyond the HashTank system?

Yes! PRASA provides comprehensive blockchain solutions, including:

  • Consultation: Leverage PRASA’s expertise to design and implement the perfect HashTank solution for your unique blockchain setup.
  • Deployment and Commissioning: From container delivery and infrastructure setup to liquid fill and system testing, PRASA handles everything for a seamless HashTank deployment.
  • Ongoing Maintenance and Support: Enjoy ongoing maintenance and technical support to ensure optimal performance and reliability of your HashTank system.
  • Additional hardware and infrastructure: PRASA can also provide pre-configured mining rigs, power management solutions, and other equipment to create a complete blockchain ecosystem.

How does PRASA's HashTank compare to other immersion cooling solutions for blockchain applications?
