linux will kesaribath files as usual if it is a regular block device - the OS cache anyway if the local CDM /dev/sdX iscsi, or network block device.
If you are not satisfied with the speed of iscsi start with network speed and MTU then you can fix readahead.
Well. Clear.
I just have a situation on the server it is possible to put 16Gb of memory. And I need it?
I have snapshots will be stored on a RAID0 of two SSD.

I read that sometimes snapshots fill up the RAMDISK, then Yes, memory is necessary the more, the better. - joe67 commented on March 23rd 20 at 19:11
