    raidix eraraid on 4 nvme - request your perf test

    You have zero clue, what you are talking about. Instead you post some articles and none of your own tests and findings. +You are unable to see a difference between Marketing, Rumours and Tech. Seriously get a life. +Ignore

    That article is the source of your facts? Seriously? Obviously I did exactly that: ask and received facts from Xinnor. What does that make you? No need for 2nd class. --- PS: So, just to get it right: you spread false rumours only to post articles. Articles which sound more like bought ads...

    raidix eraraid on 4 nvme - request your perf test

    Seriously spreading false rumours is exactly what Russia does. Interestingly you do the same. Coincedence? So no, xinnor is not funding Russia or Russia's war at all, actually more on the funding side for #Ukraine. And I lack words for people like you.

    raidix eraraid on 4 nvme - request your perf test

    Hints on server sizing: Single threaded, sync loads are 1 core only loads. At 6-8+ current Enterprise SSDs you can put a core on an Epyc 7003 system at 100% load easily. In production for this you want a 7003+ Epyc (7443(P) for low budget imho minimum) or current TR Pro, optionally Ryzen 9 7950...

    Xinnor, former raidix is now a pure Israel company. Tbh I didnt find any getting close to eraraid performance. Imho it is very mature and stable. Yet cope with it: its a scissor, a razor, not a hammer. Meaning RTFM.

    raidix eraraid on 4 nvme - request your perf test

    Works like a charm. Personally I had to learn much more about storage caching than I anticipated. Some findings: RTFM - it's all in the manuals. Those are exceedingly good and precise. Tuning: you must tune the RAID to your workload. You can tune it for low latency (eg. iSCSI, SRP, iNVME), high...

    Nope, no longer. Raidix is now Xinnor, an Israel company. Actually they decided on that move around March 2022, meaning I see their move as protest and not opportunism.

    Tbh: I dont know, why I didnt look twice - figure the low µ-latency plain got me really early in the morning. Then again nice reason to do it right - thats why I dont delete the thread, but instead update with new numbers, latest Sat noon.

    This. You are 100% correct. (Sitting here blushing that I didnt cross-check once more after 1 month of testing). Will do, need some time. PS - @ectoplasmosis : Except one value (SEQ1M Q8T1) the values are actually physically possible. Thats exactly where I should have seen it for a RAID5...

    raidix eraraid on 4 nvme - request your perf test

    Plain discussion only and ofc curiosity for additional input to improve. What buffled me on today's test run are the 40µs latency, which made me like: ooook, just post on sth and see for the opinion of others. Apart from that, eraraid is free for up to 4 drives - so its an option for any home...

    Do EPYC Milan CPUs even exist for sale?

    Sorry not from me since I dont live in the US

    Epyc 7443P and all those missing 7003 Epycs + next Threadripper info

    Meaning you want one, but dont get one? Which country are you in? Esspecially in Europe I can help ya.

    Epyc NVME 7443P

    You are correct. Thanks for pointing it out. So lets see when I am going for that another 256GB RAM... ;)

    Epyc NVME 7443P

    Figure I check speed on next boot first and see from there. Ill keep the results posted. And yes, not a memory geek, but still surprised.
