DPM 2016 new server thoughts? Storage Spaces and other questions?

[markm75]

We are in the process of buying a new server.. our old one is 2012 DPM and has about 10TB of data that is backed up going back 30 days to HDD, over 30TB in physical size.. roughly 4 different raid6 arrays of sata II and III drives..

 

Im building a new box with the goal of 2016 in mind.. i guess the new one should reduce space and utilize storage spaces ideally? Info seems vague to me..

 

Do i still go about building a monster system (in size) with dedicated controller card / expander.. and in our case the usual 16-24 drive bays (3.5") (supermicro plus xeon single processor E5-2620 v4).. i was originally thinking of the sas 12gb with 7.2k drives.. roughly 6TB x 7 raid 6, with os mirrored with raid1 and 1TB.. I can build this setup for around $5500 vs alot more with a prefab dell system or even a refurb, fairly certain.

 

How are failures handled with Storage Spaces.. i think you dont use raid on the sub level here right? So is it just the number of drives = the array size plus however many drives dedicated for failures (within storage spaces?)

 

I read about dedup vs storage spaces and the modern system.. i really never understood what dedup did exactly, but assume with the refs and storage spaces, space is reduced anyway, compared to 2012..

I wasnt thinking of virtualizing any of this, not really sure the advantage anyway.

 

Anyone gone through this and can offer some suggestions?

 

Thanks in advance
