Cobalt RaQ
The Cobalt RaQ is a 1U rackmount server product line developed by Cobalt Networks, Inc. (later purchased by Sun Microsystems) featuring a modified Red Hat Linux operating system and a proprietary GUI for server management. The original RaQ systems were equipped with MIPS RM5230 or RM5231 CPUs but later models used AMD K6-2 chips and then eventually Intel Pentium III CPUs for the final models. The Cobalt RaQ was the second product line produced by Cobalt Networks; the first was the Cobalt Qube. Server specifications Below is a list of Cobalt RaQ types, and their specs. Under an OEM arrangement, RaQ 2 units were also produced by Seagate, in the form of the Seagate NasRaQ. There were variants of the RaQ 3 and RaQ 4 models known as the RaQ 3i or RaQ 4i ( SCSI support, two Ethernet connectors, PCI connector), and the RaQ 4r (SCSI support, two Ethernet connectors, and RAID). RAID on these models was accomplished in software using a second IDE channel on the motherboard for ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cobalt Networks
Cobalt Networks was a maker of low-cost Linux-based servers and server appliances. The company had 1,900 end user customers in more than 70 countries. During the dot-com bubble, the company had a market capitalization of $6 billion despite only $22 million in annual revenue. In 2000, the company was acquired by Sun Microsystems and in December 2003, Sun shut down the Cobalt product line. Cobalt was the most successful web server appliance vendor of its time, and that success motivated the founding of blade server pioneer RLX Technologies. History The company was founded in 1996 by Vivek Mehra as Cobalt Microserver. In June 1998, the company changed its name to Cobalt Networks, Inc. The company introduced products as follows: On November 5, 1999, the company became a public company via an initial public offering. Its stock price rose as much as 618% above its $22/share initial price. On March 23, 2000, the company announced the acquisition of Chilisoft from Charlie Cryst ...

Cobalt RaQ2 Debian
Cobalt is a chemical element with the symbol Co and atomic number 27. As with nickel, cobalt is found in the Earth's crust only in a chemically combined form, save for small deposits found in alloys of natural meteoric iron. The free element, produced by reductive smelting, is a hard, lustrous, silver-gray metal. Cobalt-based blue pigments (cobalt blue) have been used since ancient times for jewelry and paints, and to impart a distinctive blue tint to glass, but the color was for a long time thought to be due to the known metal bismuth. Miners had long used the name ''kobold ore'' (German for ''goblin ore'') for some of the blue-pigment-producing minerals; they were so named because they were poor in known metals, and gave poisonous arsenic-containing fumes when smelted. In 1735, such ores were found to be reducible to a new metal (the first discovered since ancient times), and this was ultimately named for the ''kobold''. Today, some cobalt is produced specifically from one of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SCSI
Small Computer System Interface (SCSI, ) is a set of standards for physically connecting and transferring data between computers and peripheral devices. The SCSI standards define commands, protocols, electrical, optical and logical interfaces. The SCSI standard defines command sets for specific peripheral device types; the presence of "unknown" as one of these types means that in theory it can be used as an interface to almost any device, but the standard is highly pragmatic and addressed toward commercial requirements. The initial Parallel SCSI was most commonly used for hard disk drives and tape drives, but it can connect a wide range of other devices, including scanners and CD drives, although not all controllers can handle all devices. The ancestral SCSI standard, X3.131-1986, generally referred to as SCSI-1, was published by the X3T9 technical committee of the American National Standards Institute (ANSI) in 1986. SCSI-2 was published in August 1990 as X3.T9.2/86-109 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Strongbolt
Strongbolt is an operating system installation application based on the Linux operating system written by James McLoughlin. The Strongbolt operating system is specifically for Cobalt RaQ Appliance Servers. Sun Microsystems discontinued the popular Cobalt server appliances in 2004. Strongbolt was created in order to provide a new, actively developed operating system for these Server appliances. Strongbolt OS is a CentOS and BlueQuartz operating system installer for Cobalt RaQ and Cobalt Qube servers. The system installs similarly to the original Cobalt RaQ install disk. The new StrongBolt 2 release can also be installed from a USB key directly in the USB port. Strongbolt has been out of active development for several years. Internals CentOS 4.4 with an older 2.6 Linux Kernel and the BlueQuartz administration panel. Installs CentOS + Bluequartz on Cobalt RaQ3's, RaQ4's, RaQ550 and Qube3.

NetBSD
NetBSD is a free and open-source Unix operating system based on the Berkeley Software Distribution (BSD). It was the first open-source BSD descendant officially released after 386BSD was forked. It continues to be actively developed and is available for many platforms, including servers, desktops, handheld devices, and embedded systems. The NetBSD project focuses on code clarity, careful design, and portability across many computer architectures. Its source code is publicly available and permissively licensed. History NetBSD was originally derived from the 4.3BSD-Reno release of the Berkeley Software Distribution from the Computer Systems Research Group of the University of California, Berkeley, via their Net/2 source code release and the 386BSD project. The NetBSD project began as a result of frustration within the 386BSD developer community with the pace and direction of the operating system's development. The four founders of the NetBSD project, Chris Demetriou, Theo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Linux Kernel
The Linux kernel is a free and open-source, monolithic, modular, multitasking, Unix-like operating system kernel. It was originally authored in 1991 by Linus Torvalds for his i386-based PC, and it was soon adopted as the kernel for the GNU operating system, which was written to be a free (libre) replacement for Unix. Linux is provided under the GNU General Public License version 2 only, but it contains files under other compatible licenses. Since the late 1990s, it has been included as part of a large number of operating system distributions, many of which are commonly also called Linux. Linux is deployed on a wide variety of computing systems, such as embedded devices, mobile devices (including its use in the Android operating system), personal computers, servers, mainframes, and supercomputers. It can be tailored for specific architectures and for several usage scenarios using a family of simple commands (that is, without the need of manually editing its source code ...

Linux
Linux ( or ) is a family of open-source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991, by Linus Torvalds. Linux is typically packaged as a Linux distribution, which includes the kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name "GNU/Linux" to emphasize the importance of GNU software, causing some controversy. Popular Linux distributions include Debian, Fedora Linux, and Ubuntu, the latter of which itself consists of many different distributions and modifications, including Lubuntu and Xubuntu. Commercial distributions include Red Hat Enterprise Linux and SUSE Linux Enterprise. Desktop Linux distributions include a windowing system such as X11 or Wayland, and a desktop environment such as GNOME or KDE Plasma. Distributions intended for ser ...

Firewall (computing)
In computing, a firewall is a network security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. A firewall typically establishes a barrier between a trusted network and an untrusted network, such as the Internet. History The term ''firewall'' originally referred to a wall intended to confine a fire within a line of adjacent buildings. Later uses refer to similar structures, such as the metal sheet separating the engine compartment of a vehicle or aircraft from the passenger compartment. The term was applied in the late 1980s to network technology that emerged when the Internet was fairly new in terms of its global use and connectivity. The predecessors to firewalls for network security were routers used in the late 1980s. Because they already segregated networks, routers could apply filtering to packets crossing them. Before it was used in real-life computing, the term appeared in the 1983 computer-hacking movie ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
