Re: NVMeoF
latency difference may be a 20usecs less but NVMe tput is significantly higher than SAS/SATA.
Even if we were to assume the argument you are making is sound in order to justify the EF570 back-end remaining SAS why change the front-end to begin with if the benefit is just 20usecs? Changing the front end for a 20usecs improvement makes zero sense!
PS. EF570 does not have 100usecs latency. Maybe internal but certainly not external and not based on any SPC1 workload published.
