Well, to be honest, I think it is time to (at least) start thinking about moving to cluster mode. A FAS2220 is a bit on the positive side as you can’t do SAN with it in C-Mode, but a 2240 can, so then you are fine. I’ve been testing quite extensive with the simulator and it actually works fine. A bit to my surprise as well I must admit, I was just as skeptical as you all. The concepts are great and the VServer virtualization layer is a great addition to the WAFL storage virtualization layer. VServers work so much better than vFilers and with c-mode you get all the scalability advantages you need.

So, I’m not surprised all the commercial people at NetApp and partners are pushing to C-Mode. If you have a technology refresh in a few years, you should definitely consider it. If you have one this year, I’m not really sure yet. Not because not all features are supported in c-mode (yet), but right now it is quite a steep learning curve if you’re used to 7-mode. You need to re-think most of your storage setup but once you do, I think c-mode will fit a lot of environments.

Bottom line: start reading and testing, I think c-mode actually is a good product.

Hi all,

 

I’ve recently attended an official event where people from NetApp in few words said:

 

“DOT 8 7-mode has done its time, it’s over, it has been a great os but It’s now time to move and push DOT 8 Cluster Mode, everytime, everywhere…” and this also if with a simple two node HA system, including 2220!

 

What do you think about? Also let us assume that cluster mode can (I add ‘theoretically’) do all what 7 mode does, don’t you think that is quite premature to trumpet this out?

 

Regards,
