High Availability Stratum Hub & Scheduler Service
What is the HASH Scheduler?
The High Availability Stratum Hub & Scheduler is an hashrate orchestration system intended for crypto-currency mining providers. It enables mining providers with the ability to lease individual mining rigs or chunks of hashrate to their end-users without interruption from failed or degraded units. The provider’s end-users receives hashrate on their pool of choice pointed at their account or address. It is built inside the Stratumsphere Management App and provided in a Software-as-a-Service forma
Mining Pool Compatibility
We have tested popular mining pools with our current algorithms and are providing a list to help you better decide which pool to utilize for your personal pool and rentals. We try our best to make our service work with every mining pool out there. However, the Stratum protocol is poorly documented and ill-defined across the crypto community and as such not all mining pools are created equally. Tests are conducted on the popular crypto-currencies associated with that algorithm. Such as Bi
SHA256 Ethash Scrypt X11 Equihash CryptoNight (Both Regular and V7) Schedulers only support one algorithm. If you want to use another algorithm, then deploy another Scheduler. We are working to support a lot more! Stay Tuned.
How do I zoom in on the graphs?
All Stratumsphere Hashrate History Graphs are able to be zoomed in on. This is useful for observing an event or issue with your workers or rentals in more detail. Animated Example Simply click and drag your cursor across the section of the graph you want to observe. Example Click Reset zoom if you want to go back to the normal view.
Understanding Hashrate Threshold
Hashrate Threshold Overview Hashrate Threshold or Threshold for short is 1 of 2 failover methods available for the HASH Scheduler. Threshold Schedulers maintain the assigned hashrate on rentals and are agnostic of the number of workers assigned. Workers with varying hashrate and specifications can be utilized with this method. Example Situation Cust
Miner-to-Miner Overview Miner-to-Miner or M2M for short is 1 of 2 failover methods available for the HASH Scheduler. M2M will provide failover for individual workers that are connected to the scheduler and assigned to a rental. If a worker falls out of tolerance, fails, or disconnects then the worker is replaced by another worker from the personal pool.
How long is data retained for?
Worker and Rental data is retained for a maximum of 7 days. Data older then 7 days is deleted from our servers. In the future we plan to provide monthly summary charts spanning up to a year under the Statistics page.
Worker Status Definitions
Worker Status Example Definitions of the worker status as viewed on your HASH Scheduler's Worker Inventory Page: Healthy - No problems, worker is operating properly. Degraded - Miner out of tolerance from baseline (Adjust Setting: Allowed Worker Deviation from Baseline Percent). Failure - No share submission within the allocated time period (Adjust
Sorting on the Worker Inventory
Sorting the worker's table is easy. Simply click on the name of the column that you want to sort. Refer to the animated example below. Example
We do not enforce any hard limits on the HASH Scheduler service. However, we have to guarantee a certain level of service to all of our customers. We cannot give you an exact number of max workers per scheduler as there is a lot of factors that come into play regarding that subject. While our infrastructure can auto-scale to fit most needs, there is always a limitation to any man-made system regardless of how well it may be engineered. Routers, database software, and storage all have their limi
Hashrate Splitting with threshold schedulers
When first-time customers see the Hashrate Threshold scheduler method they typically will ask if this means they can split their worker's hashrate. Take their 10 TH/s worker and rent out 1 TH/s to individual customers as an example. Trying to do this through our service will produce inaccurate rental results, high invalid share-rates (30-40%) and cause your worker to spin down/up frequently which will also lower it's effe
Can I point workers at NiceHash?
Stratumsphere and other rental services such as NiceHash have to proxy the stratum traffic in order to send the valid shares where they need to go. The traffic gets convoluted after going through so many systems which ends up in no authorization or high reject rates.
Understanding & Updating Worker Modes
Worker modes give an operator the flexibility to set and track their worker inventory status as well as select which workers are available for rental. Available Worker Modes Normal This is the default worker mode. Worker is available for mining, rental, or failover as needed. Internal Use Only Worker will only mine on the personal pool. Use this setting for miners that you don’t want to use for rental. Workers that you want to reserve for your own use. Workers that regu
