Serial ATA Flash Drive AP-SRFD255AXXXXR-G 1.3 Mode Configuration Apacer SRFD supports 4 static pins that can be used to program a normal operating state. The configuration of each node uses a combination of the Configuration pins and the Pushbutton (Reset) pin. Table 1-1: Mode Configuration Configuration Pin 1 2 3 4 Mode 0100 0 1 0 0 RAID 0 1100 1 1 0 0 RAID 1 Example 1.3.1 Definition The following method can be used to define the configurations.

Serial ATA Flash Drive AP-SRFD255AXXXXR-G 2. Functions 2.1 Overview Compatible with SATA Gen1 and Gen2 host controllers OS independent, Driverless, Auto Configuration FAST (RAID 0), SAFE (RAID 1) support Embedded fast RAID Processor Virtualization engine to simplify and improve utilization of storage devices Ultra-fast 3Gbps host and device port capability 2.
Serial ATA Flash Drive AP-SRFD255AXXXXR-G 2.6 Virtualization Virtualization is a mechanism, where the HBA can have an alternate view of the physical drives. The RAID Processor allows various access strategies to the connected Hard Disks and may be configured to represent n-drives as m-drives to the user. This provides the user with a simple way of partitioning storage resources according to use. For example, the processor could represent one drives as a single, large drive.
Serial ATA Flash Drive AP-SRFD255AXXXXR-G The RAID Processor supports a definition of Safe (RAID-1) set. The HBA (Host Bus Adapter) does not need to know anything about the physical arrangement of the data. To the HBA, the virtualized drive behind RAID Processor is a normal drive that just happens to be safer (fault tolerant). All error handling and Data rebuild is managed by the RAID Processor.
Serial ATA Flash Drive AP-SRFD255AXXXXR-G recovery is needed, while the first one is not complete, then the new request is converted to a Disk Rebuild Request. 2.9.2 Disk Rebuild First of all, the Disk Rebuild is really a Physical Partition Rebuild. Only then the Physical Partition spans the entire Physical Disk, the entire Physical Disk is rebuilt. Disk Rebuild is a procedure, to copy all of the contents from the “Good” Physical Partition to the “Broken” or “New” Physical Partition.
