1U2SR is a 1 USB2.0 host to 2 drive intelligent SATA II storage processor that allows users to easily deploy and manage reliable, affordable storage devices that connect to the fast, serial, hot pluggable, SATA I and SATA II host ports found in PC’s, consumer devices and servers. System designers can take advantage of the 1U2SR hardware RAID features to build high performance, reliable storage solutions that offer OS transparency thereby greatly simplifying product development as well as the user experience.
The 1U2SR modes are;
Data Mirroring (RAID 1) -allows device to automatically copy primary hard drive without any CPU loading. The SiI4723provides automatic rebuild on device replacement and auto-fail over, to eliminate any workflow interruptions.
-
Data Striping (RAID 0)-allows the device to performance stripe the drives to provide maximum throughput to the direct attached PC (RAID 0).
-
Drive Spanning-allows the device to make my two drives (same or different sizes) appear as one large drive to the host for extra capacity (Concatenation).
-
Port Multiplier or JBOD - this allows the direct attached PC to see each drive as just a bunch of drives.
Systems with pod multiplier aware hosts may take additional advantage of the 1U2SR virtualization capabilities to segment hard drive capacity into multiple storage partitions, each appearing to the host as a different target device. Based on how the 1U2SR is configured, these partitions can have different performance or reliability properties to suit the application(s). This functionality and versatility allows storage system vendors to implement cost effective SATA storage solutions with RAID and virtualization capability that improve system performance and reliability, simplify storage administration and lower overall system cost.
1U2SR is designed for optimum power, performance and price .It is based on the Silicon Image’s industry leading SATA Link technology. It leverages much of the circuit innovation at the physical layer of Silicon Image's proprietary reduced-overhead Multi-layer Serial Link (MSL) architecture, which was pioneered and proven with our market-leading Panel Link?
