SUT Notes

1 Hardware RAID-0 (ServeRAID 7k) over 6 x 36GB Ultra320 15K RPM drives is used for OS, swap and logs
4 Hardware RAID-0 (2 x ServeRAID 6m) are used for file set
Each ServeRAID 6m has two SCSI channels. Each channel connects to a disk enclosure.
Total of four enclosures and 56 drives are used for file set
Each enclosure (containing 14 disks) is configured as hardware RAID-0
Two enclosures contain 28 x 36GB Ultra320 15K RPM drives
Two enclosures contain 28 x 74GB Ultra320 15K RPM drives
All drives use stripsize of 64KB
The total number of fileset directory (200 directories) is evenly distributed across four hardware drives
First hardware drive contains Directory 1-50
Second hardware drive contains Directory 51-100
Third hardware drive contains Directory 101-150
Fourth hardware drive contains Directory 151-200
First hardware drive contains soft links to the rest of directories

SUT Notes

1 Hardware RAID-0 (ServeRAID 7k) over 6 x 36GB Ultra320 15K RPM drives is used for OS, swap and logs
4 Hardware RAID-0 (2 x ServeRAID 6m) are used for file set
Each ServeRAID 6m has two SCSI channels. Each channel connects to a disk enclosure.
Total of four enclosures and 56 drives are used for file set
Each enclosure (containing 14 disks) is configured as hardware RAID-0
Two enclosures contain 28 x 36GB Ultra320 15K RPM drives
Two enclosures contain 28 x 74GB Ultra320 15K RPM drives
All drives use stripsize of 64KB
The total number of fileset directory (200 directories) is evenly distributed across four hardware drives
First hardware drive contains Directory 1-50
Second hardware drive contains Directory 51-100
Third hardware drive contains Directory 101-150
Fourth hardware drive contains Directory 151-200
First hardware drive contains soft links to the rest of directories
