PS6210X with 24 1.2TB SAS disks in RAID 50, how many RAID 5 sets?
We have a PS610X with 24 1.2TB SAS disks (10.000 RPM, model HUC101212CSS600).
The unit is currently configured in RAID 50 and has two spares. How many RAID 5 sets are actually configured? Is it 2x11 or 2x6 + 2x5 or something else?
Is it still considered safe to run this configuration in RAID 50 or are we better off converting to RAID 6?

Thanks Don. It just feels a little awkward this day and age to run 11 disk RAID 5 sets. I realize the SAS disk will have a much better failure rate compared to the SATA/near line disks, but still.
This is a recent graph of the last 30 days from the RAID evaluation:
As far as I can tell we should not see a negative impact when we convert from RAID 50 to RAID6, right?
