Hello!

 

We bought an SCv2020 with 14 disk of 1TB (one is a spare)

 

so we have 13HDD of 931gb of usuable space. When configuring the SAN, I am not sure on how the storage works and how big I can create my Volume, to make sure we don't get into a crash.

I tried asking Dell tech support on the call center, but I do not understand and the explanation wasn't really clear. I am reading the document: Understanding RAID with SC series, but seriously, it is not clear...

 

I am reading now the DSM admin document, I just want to make sure of what I am reading, if anyone can confirm me:

 

RAID 10 DM, it is a raid 10 of 3 x 3 disk

RAID 6-10, 8 data segment, 2 parity (not sure to understand, this means you have 10 drive in raid 6?)

 

Right now, the SCAN has RAID 10-DM and RAID 6-10, and I have 13 disk available. It says Available space: 11.83TB, configured 11.83TB

 

Is it really the max I can configure as a Volume? How can I calculate the maximum data I can use? I have 2 volume configured of 5.91TB and 5.92TB, and I want to make sure if we full the volume, that the SAN will not crash.
