Desktop LAN appliance offers expansion slots, choice of Atoms

Dec 13, 2010 — by LinuxDevices Staff — from the LinuxDevices Archive — 4 views

Portwell announced an entry-level desktop network appliance featuring Intel's Atom D510, D410, or N450 CPUs. The CAD-0210 comes with six gigabit Ethernet ports, hard disk or CompactFlash storage, Mini PCI Express and PCI expansion slots, and a reset button for quickly loading default settings, the company says.

Just last week, Portwell announced the CAR-1000, the entry-level model in a series of rackmountable network appliances that has previously included more upscale devices — the CAR-3000 and CAR-5000, for example. In the CAD-0210, the company is now spinning what appears to be a directly equivalent device designed for desktop mounting, again equipped with six gigabit Ethernet ports and Intel's ICH8M I/O controller.

The CAD-0210's data sheet mentions only Intel's 1.66GHz, dual-core AtomD510, but Portwell's product page and press release cite also the single-core D410 and N450 as being available choices for the network appliance. As with the CAR-1000, maximum available RAM is apparently 4GB when the D510 or D410 are installed, and 2GB when the N450 is installed; power consumption varies as shown by the Intel-sourced chart below.

Clock speed Cores Second-level cache Memory (DDR2) TDP
N450 1.66GHz 1 512KB 667MHz 5.5 Watts
D410 1.66GHz 1 512KB 667/800MHz

10 Watts
D510 1.66GHz 2 1MB 667/800MHz 13 Watts

All three CPUs include onboard graphics capabilities, but the CAD-0210 doesn't tap into these except when an optional VGA port is installed. As pictured below, the device includes an RJ45 connector for a serial console, which is its normal mode of operation.

The CAD-0210's rear panel otherwise offers six gigabit Ethernet ports (two with LAN bypass) and two USB 2.0 ports, while there's another USB port inside, according to Portwell. The front panel sports only LEDs that monitor power and the status of each LAN port.

Portwell says the CAD-0210 includes both a bay for a 3.5-inch SATA hard disk drive and a CompactFlash slot. Expansion, meanwhile, includes both a Mini PCI slot and a PCI slot, the company adds.

"Unlike commercial motherboard-based systems," the PR release also claims, the CAD-0210 includes a reset button that can be used to return the device to the manufacturer's default settings. Equipped with a 60-Watt power supply, the device works in temperatures ranging from 41 to 104 deg. F, the company adds.

Features and specifications listed by Portwell for the CAD-0210 include:

  • Processor — Intel Atom D510, D410, or N450
  • Chipset — ICH8M
  • Memory — 2 DIMM slots support 4GB of DDR2 RAM with D510/D410, or 2GB with N450
