I'm sorry, I don't know the megaraids that much.
But the more drives you have in one group the more data has to be
accessed in case of a rebuild, with increased potential for another
issue while less performance is available.
Sometimes people recommend in case of an failure to move the data to a
"With 20 disk of 4TB you have a total capacity of 80TB. If you run all of
them as RAID6 then you have a total of 72TB."
And that's the point! I'm trying to understand if I can create more RAID6
arrays and how my controller handles disk failures in that case. First I
think we need to clarify termin

If you ask your controller to create a 8TB volume, this volume is spread
across all the 20 disk
ok, first if all, thank you for your answer. This is acomplicated task and
I cannot found many guides (if you have are welcome).
I'm using RAID6 and I have 20 disks of 4TB each.
In RAID6 space efficiency is 1-2/n, so a solution for small Virtual Drive
could be 4 or 5 disks. If I use 4 disks I will

Hi, I have 2 servers supermicro lsi 2108 with many disks (80TB) and I'm
trying to build a SAN with drbd and pacemaker. I'm studying, but I have no
experience on large array of disks with drbd and pacemaker, so I have some
questions:
I'm using MegaRAID Storage Manager to create virtual drives. Each
