Because the two planets follow an egg-shaped orbit, not every alignment is equal. That’s the ideal time for a launch, as the distance between the two is reduced to around 33.9 million miles. The orbital synchronizations Musk is referring to is the point when the Earth and Mars are in closest alignment, which occurs around every 26 months.

Architectures of Cloud Storage / Software Defined Storage / Big Dataġ.1. Trademarks are the property of their respective owner.ġ. It comes with some automation scripts, leading to a similar functionality than Kubernetes,īut devoted to stateful LVs over virtual LVM pools in the petabytes range. MARS supports a new method for building Cloud Storage / Software Defined Storage, called Versions are planned to also support synchronous or near-synchronous modes. Therefore, application performance is completely decoupled from any network problems. The current version of MARS supports k > 2 replicas and works asynchronously. Operations even when the network is flaky (Anytime Consistency). In contrast to DRBD, MARS preserves the order of write Even in case of networkīottlenecks / problems / failures, the secondaries may become outdated (reflect an elder state),īut never become inconsistent. Therefore, MARS can provide stronger consistency guarantees. The sysadmin interface is similar to DRBD1, but its internalĮngine is completely different from DRBD: it works with transaction logging, similar to some MARS is a block-level storage replication system for long distances / flaky networks under GPL.
