We are designing a new Veeam backup-solution moving away from Microsoft DPM.
We have around 1000 virtual machines running on Hyper-v Clusters.
We have bought some new hardware for this and have decided to go for a
short-term / long-term design.
The short-term (7days) will have a 60-disk Dell powervault md3060e with 4TB NLSAS drives connected to a DellR740
The long-term (30days) will have a 60-disk Dell powervault md3060e with 6TB NLSAS drives connected to a DellR740
placed in a co-located datacenter.
For the long-term backups I was thinking of a RAID60 because of fault-tolerance.
For the short-term backups placed in-house it´s more easy to replace broken disks so here
I was thinking about RAID50 for slighly better write perfomance.
But what is the best way to configure the RAID arrays? 6 arrays with 10 disks in each?
For example 6 * 10 RAID6? Here I loose 12 disks if my calculations are correct.
So long story short. How would to design a RAID50/60 with 60 physical disks?
