But, that doesnât mean students have to take them all in the same week. Our class structure allows us to provide 5 cycles of classes for every 30-day period. As long as students take the classes in order, (Class 1, Class 2, Class 3, Class 4), they are free to switch between any of the cycles for that 30-day period. The only other requirement is that all 4 classes must be completed within 30 days of the first class.
Re: Advantages of three phase systems over single phase. The big advantage with 3 phase mains is that any electric motor connected to it is more efficient, has smother running and uses less parts so is more reliable. There is also a slight advantage in using 3 phase transformers over single phase ones.
But because some customers require the ability to support multiple concurrent node failures without the chance of data loss or unavailability, RF3 has been required. Enter Nutanix Erasure Coding (EC-X)! Now lets say you have a 32 node cluster where each node has 10TB RAW. With RF3 we would have approx 3.33TB usable per node for a total of 106.56TB in the cluster. With EC-X enabled (assuming EC-X has been applied to all data) the usable capacity would DOUBLE to 6.66TB per node and 213.12TB for the cluster. Hereâs how it works. For RF3, the Nutanix Distributed Storage Fabric writes and maintains three copies of each piece of data.
