You just have to look for it.
But do HDD last longer if they are unplugged. And only start up when they are needed? In that case wouldn't an NAS putting HDD to sleep most of the time would prolong the life time of HDD?
The time varies with temperature. Search for SSD data retention for more info.
The JEDEC standard is the one to read.
Stock photos cost $5 to $100 and come with distribution rights.
Somebody paid a lot of money for bragging rights.
Contact me by email if you would like a demo. (I'm trying to avoid HN overload.)
I'm sure that Solarwinds uses many more developer tools than what Jetbrains supplies. But only Jetbrains was "founded by Russians" so the NYT leads with that.
I don't think this paper covers anything particularly new, but writing it down in this form, with the evidence they present, is very valuable. Hopefully this paper will deepen the conversation about applying control theory to distributed systems design and control problems, and allow a more theoretical approach to be taken to the design of these systems to avoid common causes of instability and bistability.
One of the authors has a great summary of the paper on his blog: http://charap.co/metastable-failures-in-distributed-systems/
I wrote a summary and discussion too: https://brooker.co.za/blog/2021/05/24/metastable.html
However it suffers from (a) weak definitions and (b) implausible or strange descriptions.
For (a), what is a "strong feedback loop"? Does it have high gain (low error) or high bandwidth (fast)? Is it hidden (the accidental link imbalance example)? Is it obvious (the cold cache example)? What makes it "strong"?
Or, conversely, what is a "weak" feedback loop?
A number of acronyms are undefined (SRE, LIFO). I think I know what they mean, and most HN readers will too. What about the other readers?
And using Wikipedia to define metastability? There must be a more persistent or academically defendable reference. Wikipedia is OK for informal definitions. In a paper calling for more academic studies this is ironic.
(b) Section 2.1 "When replicas are sharded differently..." Huh?
Section 4 "upper bound" used as a verb. Should be "limit or place bounds on".
Section 4 "The strength of the loop depends on a host of constant factors from the environment..." Odd, the term is not defined but this is the second dependency listed. Very strange.
In short it needs/needed a better reviewer.
That all said, it has summarized a lot of good ideas on controlling stability in distributed systems.
