Hi Neil et al, I have some questions I am hoping you or anyone else on the list can help me with. I am researching the new Intel Kaby Lake processor, the i7-7700K. My information so far is specifically from the first page of the Anandtech article about it:
http://www.anandtech.com/show/10968/the-intel-core-i7-7700k-91w-review-the-new-stock-performance-champion. The article says that Kaby Lake will have support for a new version of RST for PCIe-based storage but doesn't explicitly state anything about Optane Memory capabilities. I can't tell if it is something that will be arriving in q3 _AND_ be usable by the i7-7700K Kaby Lake processor or if there's more to it than that. Does its mentioning in the article imply the i7-7700K has support built in? I am trying to wrap my head around what I will need to put in the new system to have all the features available to me as I move forward with the purchase. Hmmm... Or should I wait a bit? Focus on Skylake instead? These are the questions that spin in my head! I also saw a /. post that panned the new Kaby Lake... Anyway, one of the reasons I come to you with this inquiry, is that I think PCIe-based RST and Optane Memory technologies further enhance what you were describing at the last meeting and so you probably have more familiarity with the concepts involved than I do. What you described at the meeting was using bcache (in the kernel) to speed up document retrieval, with an SSD as the storage device for the cache. I understood that the purpose of the setup was to limit the necessity of going to the mechanical drive for data, but also to reduce the hits that an SSD would experience if it were to be the only drive in the system, thus also prolonging the lifetime of the SSD. Putting together bcache and Optane Memory I imagine they would look something like this (simplified). I hope my ASCII works!: /---> mechanical drive request -> bcache /---> Optane Memory \---> SATA or PCIe RST ---> \---> SSD Any thoughts? At the end of the day I will be most interested in the status of support for all these technologies in the Linux kernel... but that is the next step - to take more detailed questions to the kernel people! Of course, if anyone here knows anything about any of this jump on in! I also like that the i7-7700K is unlocked :-) Thanks! Jacob
