That was the subject of the following paragraphs. I agree that is likely the key enabler for a space CDN. Some mentioned SSD density is too high for space. We're used to some hard errors in flash, is the space error rate too high to cope with, even with increased sparing? Or is it the soft error rate that is too high? At least for a CDN the soft rate is less of an issue as it is invalidating cache entries all the time, this is just a new reason to that requires detecting, and perhaps a less than whole file invaliation for more efficient replacement. brandon _______________________________________________ Starlink mailing list [email protected] https://lists.bufferbloat.net/listinfo/starlink
