As you know, TOS Aurora is public and will result in the only supported version. TOS Classic will retire end of 2022.

Before upgrading from TOS Classic to TOS Aurora, the requirements need to be considered. If you are using a Tufin Appliance, please consult Tufin about its compatibility.

If you want to install TOS Aurora on other hardware, please refer to Tufin and consider the requirements.
Not only the size of the hard disk is important, but also the speed of it. Do not try to install TOS Aurora on classic hard disks...

  • (fast) SSD array
  • 7.500 IOPS or more
  • 250 MB/s throughput or more

So besides the requirements for processors/cores, RAM, and disk size, the speed of the hard disk is very important.
