Hi

Hardware:

FAS 2240-4 NetApp Release 8.2.4P6 7-Mode 24*1TB-SATA-Disks, FС 8G

 

Tell me where is the bottleneck for reading.
Netapp disk system reads a maximum of 200 mb / s

I copy a large zip file of 90 gigabytes, a compressed backup copy of the database.

Copying from LUN on fiber channel 4gbit and further on the local network 10 gigabits to a RAID 0 server

I would like to have a speed of ~ 300 mb / s

The disk system cannot handle writing, it shows sysstat well, but I don’t see any bottlenecks with reading

NVRAM bottleneck ???

Think of ONTAP as a dam,   It's designed to take as much water on as it can within its design (writes) ,  however, it can control how much it will release the water (read).   And controlled release, is safer and more stable than just letting it all go at once as that could destroy the damn.
