I have a couple Netapp3020's that i need to add a storage too. I did a sysconfig -a and got the following. Is there a command that will show me the model name & # of each disk shelf attached? I believe they are DSMK2 1TB shelves. Is there a better shelf that i can purchase or is it best to just stick with the existing model i currently have in production? If a different model is recommended would i have to put them on a new loop? These are for small offices (5-20) employees each running CIFS only and snapmirror to replicate data to offsite location.
The "best" (subjective to opinion) compatible shelf that you can attach to a 3020 is a DS14-mk4-FC with ESH4 modules. Having said that, those disk shelves are EOL and might be EOS. So honestly I'd reach out to your sales rep and see what they can do for you. That controller doesn't support Data OnTap 8.X either making it more and more difficult to get support. If you're looking into adding new shelves it might be worth looking into a shiny new 8020 or a 25XX with DS2246 disk shelves and SAS/SSD. Or if that's not in your budget think about a 32XX with DS4243 disk shelves with SAS disk.
We have M+S for each of our fas3020 and there dsmk2 through zerowait. I guess I will have to reach out to them to see if they are selling any. Pretty sure the It director will not want to do a forklift solution for these small offices.
One question, can you attach a ds4243 to a 3020 on a new loop?
If we were to upgrade we would look at redoing our HQ site which has a 2240HA which are running ds4243 7200rpm & 15sas spindles. I have two of them (one is in our DR site utilizing snapmirror to replicate daily) so we would repurpose one to each site and refresh HQ which has CIFS, iscsi (vmware) running on it. But I believe the IT director is trying to stretch the 2240's life 1-2 more years and just pay M+S on them then refresh. If only we had more $$$ ...:)
Here's the deal. the DS4243 are attached with QSFP SAS connections. The 3020 doesn't have a supported SAS card to install on them. So the short answer is no it's not supported. Check the Hardware Universe.
