Rackmount server targets LAN security threats

May 12, 2011 — by Eric Brown — from the LinuxDevices Archive — views

Acrosser Technology announced a 1U rackmount network server that can be equipped with Intel Core 2 quad-core or dual-core processors, as well as Pentium or Celeron CPUs. The AR-R5800 offers eight gigabit Ethernet ports, two LAN bypass pairs, four USB ports, dual SATA hard disk drive (HDD) bays, and PCI Express expansion, the company says.

The AR-R5800 is designed for network security applications,   VPN, firewall, anti-virus, anti-spam, QoS, and streaming, says Acrosser. (Other recent rackmount networking appliances from Acrosser include the AR-R6000, which offers four gigabit Ethernet ports and is based on an Intel Atom D410 or D510 processor.)

The AR-R5800 can pack considerably more power, ranging from an Intel Celeron or Pentium processor all the way up to a dual- or quad-core Intel Core 2 processor clocked at 3GHz. The network server can be equipped with up to 4GB DDR3 RAM, and offers a CompactFlash socket. Dual 2.5-inch hard disk drive (HDD) bays are served by dual SATA 2 ports with RAID 0 and 1 support, a feature enabled by the built-in Intel G41 + ICH7R chipset, says the company.

The system ships with eight gigabit Ethernet ports, two of which offer software and hardware configurable LAN bypass functionality, says Acrosser. The LAN ports support 02.1p (QoS), 802.1q (VLAN), IPv4 and IPv6 checksum offload, and auto MDI-X, says the company.

Four USB 2.0 ports are provided, but two of those are available only via headers, says Acrosser. One RS-232 port acts as a console port, while a second can be hooked up via a header, says the company. GPIO is also said to be available.

A PCI Express socket is offered for expansion, and the Acrosser press release (though not the data sheet) mentions a mini-PCI slot too. For visuals, a VGA connection is available via a header, and there's a 16 x 2 character display with four buttons, says the company.

The 1U rackmount system can be installed in a standard 19-inch rack, and is powered by an "80 Plus Bronze" power supply unit that can "save the electricity bill and protect the environment," claims Acrosser. No power consumption figures were provided, although they would likely vary considerably depending on the processor used.

Features and specifications listed for the AR-R5800 include:

  • Processor — Intel Core 2 Quad, Core 2 Duo, Pentium, or Celeron, up to 3GHz
