I am currently developing the Linux driver support for RAIDZONE technology.
RAIDZONE is a complete RAID solution that ultilizes Ultra ATA (a.k.a. EIDE
UDMA) disk
drives. Using RAIDZONE it is possible to build Linux servers with a
significant
number of Ultra ATA drives - the most I've configured so far is 60.
What's really amazing is the price/performance potential.
Consider these bonnie results:
System: 400Mhz PII with 256Mb EDO.
OS: Linux 2.2.0-pre6
FileSystem: ext2
Raidzone: 1 SmartCan populated with 5 Ultra ATA Seagate Medalist Pro 9140
drives.
Raid: Software Linux RAID 0 across 5 drives.
Test: bonnie -s 1024
