I have a mission to upgrade my single FAS 3020 to cluster FAS 3050.

With the help from NetApp professional service team, i managed to

  • Removed the 3020 head and replaced with new 3050 head and re-own the disk.
  • Setup cluster environment.

Here is the detail for my 3020:

Ontap 7.2.4

FC disk shelf x 6

4 port-channel network cable

My ultimate goal:

  • Upgrade to Ontap 7.2.6.1P2
  • Upgrade all Firmware(disk,disk shelf….etc)
  • Setup cluster(filer A & B)
  • snapmirror 2.8TB over to filer B.

The upgrade finished successfully and smoothly. The challenging part will be snapmirror. We have 2 days down time and was hoping the snapmirror to finish ASAP.

NetApp told me the rough calculation is :

~200GB / hour = 14 hours for the snapmirror if everything goes well.

During the snapmirror ,  there were no activities on both filer except snapmirror.

The destination(filerB) CPU load was ~45%(sysstat -m) and the speed was about 220GB/hour.

I am so glad that the snapmirror for 2.8TB finished within 12hours. Oh ya, the filer B is also configured with 4 port channel network.

I searched for so many sites and there is no article/blog mentioning about the snapmirror time, you may refer to NetApp for the data or just refer to my post 🙂
