Las Vegas, Nevada -- Storage Visions Conference/Consumer Electronics ShowPLX Technology Inc. has rolled out its NAS 7800 system-on-a-chip (SoC) family, its third generation of consumer network attached storage (NAS) SoC solutions.
Two of PLX's latest SoCsthe NAS 7820 and NAS 7821are being touted as high-performance, low-cost devices that make NAS more attractive in the home as a central, powerful storage platform. The top-end NAS 7825 SoC enables higher levels of integration and functionality, supporting new markets for NAS, including routers/gateways, DVRs, and set-top boxes.
PLX doubled overall performance of the previous generation by implementing its highly optimized Trident architecture, which combines a dual-core ARM 11 multiprocessor with multiple NAS application specific-hardware engines and software acceleration modules. According to PLX, the Trident architecture provides high multi-client NAS performance, while simultaneously running multiple software applications. Some of the optimized acceleration functions include encryption, hashing, RAID, audio, VoIP, and routing.
The NAS 7800 line requires very few additional components to build a system. No external memory is required on the board as the device can boot from the disk drive. The NAS 7800 system runs on highly optimized Linux-based software to maximize NAS transfers and leave a large percentage of the system resources for applications.
The NAS 7825, integrates dual ARM 11 processors, as well as a network co-processor, and is loaded with IO, including dual RGMII, dual SATA, dual USB 2.0, and dual PCI Express 1.0 ports. The dual RGMII ports are required in router applications, dual SATA ports to support multiple drives, and the dual PCI Express ports to allow the addition of other peripherals or functions such as Wi-Fi.
The NAS 7820 and NAS 7821 each incorporate the dual processors plus all the hardware and software acceleration modules of the Trident architecture, but with less IOs, which enables designers to match the functionality and price sensitivity of standard home consumer NAS applications.
Pricing: Volume unit pricing is $15 for the NAS 7825, $13 for the NAS 7821 and $11 for the NAS 7820.
Availability: General sampling and Rapid Development Kits (RDKs) are available in Q1'10, followed by full production in Q2'10.
