Dear Sirs.

I have a ML370 G4 server with 2 disk SCSI Ultra 320 of 300 GB in RAID-1 through a controller and operating system CentOS 4.7.

My question: CentOS 4.7 could support the expansion of capacity by adding 6 disks SCSI Ultra 320 of 300GB in Raid-1?

Yes, the only requirement is that the controller is recognized if you are adding an additional controller. However, Raid-1 normally means paired, mirrored partitions, so in this configuration you would be adding 3 new mount points, not additional contiguous space. There are advantages to this approach if you can control the paths used for storage - for example, you can recover data from any single disk.
