80TB StorageVault Recommendations?

[PerryGuy621]

We're looking at building and 80-100TB StorageVault that we can back up to with Veeam. We've bounced back and forth between Raid6 with 24-4TB drives and have 2 hot spares or a Raid10 setup with 40-4TB drives. The Raid 6 setup would have insane rebuild times but the Raid10 is a ton of drives and not sure how well a storage array that big would be used/recognized. What would you guys do? Any other options we may be missing?

You should probably consult with Veeam support. I know the old dedup method required a very beefy amount of IOPs for good performance but now if I'm not mistaken they recommend using ReFS as it integrates very well with the backend architecture of that so instead of doing hash based dedup which is CPU and I/O heavy they use the metadata capabilities in ReFS to track duplicate data blocks instead.

 

This might actually be a case where it's best to use a Windows storage server.

 

Anyway for a backup store I really wouldn't use RAID 10 just from the cost per GB perspective, unless you can stage the data first to a smaller RAID 10 then move to a bigger slower RAID 6.
