I have 24 2TB disks in my server controlled by an Adaptec 5405.
I added 4 RAID sets:
2 x 2 TB 1x 1TB and one 15GB.
So there is plenty of space left. Interestingly enough though, when I want to add more sets the available disk list is empty. Why? I cannot create bigger Sets, because this server is for vmWare and ESX does not recognize disks greater than 2TB.
Thanks for your help.
