VT6420 User Manual – SATA Controller
Revision 1.01, May 19, 2003 2 Introduction
JBOD (Spanning)
A spanning disk array is equal to the sum of the all drives when the drives used are having different capacities. Spanning stores
data onto a drive until it is full, then proceeds to store files onto the next drive in the array. When any disk member fails, the
failure affects the entire array. JBOD is not really a RAID and does not support fault tolerance.
Key Features
The VIA SATA RAID solution uses the VT6420 chip as a RAID controller, which is a 2-channel SATA and 1-channel ATA133
solution. The RAID software is a Windows-based software utility with graphical user interface that provides an easy-operating
tool to configure and manage disk drives or disk arrays connected to the VT6420 controller. Listed below are the main features
and benefits of VIA SATA RAID:
1. Support two SATA + two PATA or four SATA hard disk drives.
2. Only SATA supports RAID.
3. Supports ATA 133 high performance hard disk drive.
4. Supports hard disk drive larger than 137 GB (48-bits LBA).
5. Dual independent ATA channels and maximum connection of four hard disk drives allowed.
6. Supports Ultra DMA mode 6/5/4/3/2/1/0, DMA mode 2/1/0, and PIO mode 4/3/2/1/0.
7. Supports PCI Plug and Play. PCI interrupt sharing and coexists with mainboard IDE controller.
8. Supports IDE bus master operation.
9. Supports RAID 0, 1, and JBOD.
10. 4 KB to 64 KB striping block size support.
11. Bootable disk or disk array support.
12. Windows-based RAID configure and management software tool. (Compatible with BIOS)
13. Real-time monitoring of device status and error alarm with popup message box and beeping.
14. Supports hot-swap failed disk drive in RAID 1 array.
15. Mirroring automatic background rebuilds support.
16. ATA SMART function support.
17. Microsoft Windows 98, Me, NT4.0, 2000, XP operating systems support.
18. Event log for easy troubleshooting.
