It delivers a wide arry of consumer specific applications such as media server and atomatic backup combined with easy-touse software making it ideal for mainstream consumers who need to store and share their digital information. The device supports two hard disks in a RAID 1 configuration. The OXE810DSE has an outstanding price/performance ratio with a high level of integration and includes advanced encryption capabilities in hardware. It offers diverse connectivity including 10/100/1000 Ethernet plus CIFS over TCIP/IP, XFS and EXT3. This adaptable and highly-configurable device also supports connections to IEEE 802.11 and other standard wireless chips via Mini PCI. It provides two integrated SATA port, a USB high-speed port and two USB full-speed host ports supporting additional expansion capability via USB HDDs. Embedded ARM Processor An integrated ARM926EJ-S processor @367MHz, featuring an MMU and 32 Kbyte caches, runs Linux OS with a full network stack. For system control, there is an integrated fan tachometer/thermistor controller and pulse width modulators. Used in conjunction, these facilities can optionally trigger and modulate a fan or initiate protective measures. SATA Interface The embedded 3GHz SATA host interfaces supports the latest revisions of the SATA II specifications. Interface speeds of 3GHz and 1.5GHz deliver maximum performance with minimum latency for external SATA storage. RAID The RAID controller supports mirroring (RAID 1) providing the highest level of data integrity with 100% data redundancy, disk spanning (concatenation) presenting all drives as a single large volume, or two independent disk configurations. USB Multi-Port Host Controller The USB can be used to connect to external USB HDDs via the high-speed 480Mbps port A, or to other peripherals, such as printers or USB memory via the full-speed 12-Mbps ports B and C as well as port A. The controller has its own DMA engine to collect and store packets either in internal SRAM or external SDRAM. Static RAM Controller The static memory controller can interface to any static memory type device. In addition to static RAM, it can also interface to intelligent LCD controllers and NOR flash. © PLX Technology, www.plxtech.com Page 1 of 1 4/8/2009, Version 1.0 OXU810DSE, Dual Drive NAS System Device with Encryption Product Ordering Information PCI Controller The PCI core can be configured as a host or device under software control. It can be used to communicate with planar PCI devices or mini-PCI cards such as SATA controllers and 802.11 wireless LAN controllers. In PCI host mode the controller can support up to 4 external devices on the bus.
