INTRODUCTION
1. Introduction
Sans Digital MobileRAID RAID subsystem is designed for SOHO or
small business to extend storage capacity and secure their data as
hard disk failed. The MR5CT1 comes with Firewire 800, USB2.0 &
eSATA host interfaces and five SATA ll channels for disk drives. The
MR5S1 supports 320 SCSI host channel and five SATA ll channels
for disk drives. The RAID subsystem is designed with a high-performance
SATA ll drive bus disk array Controller. When properly
configured, the RAID subsystem can provide non-stop service with
a high degree of fault tolerance through the use of RAID technology
and advanced array management features. The RAID subsystem
connects to the host system through Firewire 800 or USB2.0
or eSATA or SCSI interface. The HOST interface on the host may
be located either on the system board, or on a plug-in host bus
adapter (HBA) card.
The RAID subsystem allows easy scalability from RAID 0 to RAID 6.
It can be configured to RAID levels 0, 1, 10, 3, 5 and 6. The RAID 6
function allows two HDD failure without impact on the existing data
and failed drive Data can be reconstructed from the remaining data
and parity drives. RAID configuration and monitoring can be done
through the LCD front control panel or serial port/LAN port.
MobileRAID subsystem is the only available RAID solution that does
not require a conventional PCI slot. It uses the standard protocol to
connect the host system controller, just like SCSI or SATA. It is also
a standard part of all major operating systems such as Windows
95/98/2000/NT/ME/XP, Novell, MAC, Linux, UNIX, etc., the host
system does not require additional or proprietary software to work
with the controller.
1.1 System Architecture
1.1.1 Firewire 800/ USB 2.0/ eSATA Interface
The MR5CT1 host interface appears to the host system as a eSATA
target device or a removable Firewire/USB device . The eSATA interface
can support transfer rates of up to 150MB per second. The
Firewire 800 can support transfer rates of up to 80MB per second.
Both Firewire 800 and eSATA interfaces can concurrently access
