Links of the day 25/11/2015: Micron NVDIMM, Ceph load balancer, Programming with Promise

  • Micron Persistent Memory & NVDIMM : Micron announced the production of 8GB DDR4 NVDIMM. Similar to the diablo tech, viking nvdimm. However for some reason Micron decided to externalize its super-capacitor to an external module compare to the other vendor who integrated it on the stick themselves. The trade-off is that you can fit more silicon on a stick however it obviously restrict the HW they can deployed onto. [slides]
  • Mantle: a programmable metadata load balancer for the ceph file system. It allows the user to dynamically inject information into the Ceph load balancer in order to optimize data placement and hence performance of the overall system
  • How do Promises Work? : excellent coverage of the promise technology, how it works, when to use it (or not) and how to avoid some of its pitfall.
