I'm trying to create two RAID10 arrays using LSI MegaRAID's WebBIOS utility.
If I understand correctly, I must create many two-disk RAID1 pairs called "disk groups" and then span those disk groups together to get the striping layer. Then I can afford to lose one drive from every two-drive RAID1 disk group without suffering a data loss. Right?
The problem is that I have 10 SSD drives and 10 SAS drives. But I can only create 8 disk groups. That's 16 drives. What gives? Will I have to settle for RAID01 creating 5-drive RAID0 and mirroring it with another such array?
