Implementing SSD caching in a QSAN XCubeSAN

Implementing SSD caching in a QSAN XCubeSANstorage system. 3r3-3596. 3r3-31. 3r33570. Productivity technologies based on the use of SSD and widely used in storage systems, have long been invented. First of all, it is the use of SSD as storage space, which is 100% efficient, but expensive. Therefore, in the course are the technology of tiring and caching, where SSD are used only for the most popular ("hot") data. Tiring is good for long-term (day-to-week) use scenarios. And caching, on the contrary, for short-term (minutes-hours) use. Both of these options are implemented in storage 3r3-3582. QSAN XCubeSAN. In this article we will consider the implementation ...

RAID EE technology in Qsan

RAID EE technology in Qsanstorage. 3r3187. 3r3-31. 3r3168. RAID algorithms have long been a generally accepted standard in the field of data storage, providing specified reliability and speed of access. Although RAID variations are not small, currently the main levels are levels ? 5 and 6 (plus their combinations with zero level). But their further development in the form of RAID EE made it possible to increase their strengths as well as reduce some of the existing disadvantages. 3r3173. 3r3174.  3r3187. 3r33150. Qsan Technology 3r3172. just one of the few who implemented the possibility of using RAID EE in their products (starting ...

Russian distributed storage. How everything is arranged

Russian distributed storage. How everything is arranged  
 
This spring, the Rejdiks team produced and released the first version of the software for creating distributed block storage on the Elbrus-4.4 server platforms based on Elbrus-4C microprocessors.
 
 
The usefulness of this symbiosis is visible to the naked eye - the storage assembly on the basis of domestic hardware and the domestic operating system becomes quite an attractive product of the domestic market, in particular for customers who have a focus on import substitution.
 
 
However, the potential of the developed operating system is not limited to Russian server platforms. At the moment, compatibility ...
