Of course with the development of technology, reduced cost, SSD is likely to replace the mechanical drive, become the main medium of the next generation of enterprise storage, mechanical hard disk may be into a magnetic tape,
However, flash speed really is the limit of the storage system now? Now have need based on the database memory, such as Redis TimesTen, excellent practice memcached also have to mention the cache system, spark are all operating in the middle of the data into the memory, avoids the problem of poor Hadoop real-time and availability, likely the Hadoop ecosystem, which has a far-reaching influence spark in February 27, 2014, already became the Apache foundation top project,
RAMCloud, is a fully use of DRAM storage system, all of its data is stored into the memory, will certainly to recovery RAMCloud log and data backup persisted to the ordinary hard disk,
Want to know how to realize the RAMCloud memory management is? Why it does not use malloc and building cars? Please click blog http://blog.csdn.net/anzhsoft/article/details/21830991
This blog is recommended to CSDN website homepage, believe that will be something after you finish reading,

Bat is said to have the whole memory of server cluster,The problem is that the capacity of RAM up will be very inefficient, and inconvenient for persistence, and cost is low, not only as a general cache, memory database, to the bat, 12306 the Grosvenor LTD handsome with
Also have provide the memory of cloud storage providers:
