HP server for SMB3 SOFS

[frankive]

I am looking to expand our storage. We want it to be redundant. We are happy with our HP P4300 but we think the storage is way to expensive compared with our usage.
I am looking at the Windows Server 2012 R2 SMB3 SOFS-cluster with two servers acting like an active-active san through the smb3 protocol.
Does anyone have a recommendation on which HP server to pick for this and if I should use Raid or storage spaces based on your experience so far?
I think I will look for a DL-380 G8 with 8 LFF discs with 3TB each. I guess 8GB Ram should do it for plan SMB3 server or should I take more as Veeam also will take backup of this?

Edit: Seems like HP Storeeasy 1630 42TB could be a good match. It comes with an preinstalled OS, seems like it is Windows Server 2012. I am not sure how smb3 can compare in 2012 and 2012?

I cannot comment on the particular storage model, however can point you to the brief what's new for SMB 3.0 in Windows Server 2012 R2.
