	Mainframes - CIO.com - Business Technology Leadership
		Just proving that your mainframe saves money for the company is not enough anymore.
		You also must prove that IT is helping to bring in new revenue.
		Fortunately, technology can help you extend your mainframe to help in that effort.

	Mainframe computer - Wikipedia, the free encyclopedia
		Mainframes (often colloquially referred to as big iron) are large and "expensive" computers used mainly by government institutions and large companies for mission critical applications, typically bulk data processing such as censuses, industry/consumer statistics, ERP, and financial transaction processing.
		Nearly all mainframes have the ability to run (or "host") multiple operating systems and thereby operate not as a single computer but as a number of "virtual machines." In this role, a single mainframe can replace dozens or even hundreds of smaller servers, reducing management and administrative costs while providing greatly improved scalability and reliability.
		The distinction between supercomputers and mainframes is not a hard and fast one, but generally one can say that supercomputers focus on problems which are limited by calculation speed while mainframes focus on problems which are limited by Input/Output and reliability.

	IBM mainframe - Wikipedia, the free encyclopedia
		An IBM mainframe is a large, high-performance computer made by International Business Machines (IBM).
		Mainframe computers traditionally are expensive, physically large, and have high transaction processing and I/O performance, but are not as expensive and high-performance as supercomputers.
		IBM mainframes run all the major enterprise transaction processing environments and databases, including CICS, IMS, WebSphere Application Server, DB2, and Oracle.

	IBM MAINFRAME FORUM : Career growth in Mainframes?
		The advent of minicomputers in the seventies and desktop PCs in the eighties was expected to ring the death knell for mainframes, which were considered to be large, inflexible, expensive and difficult to use.
		For instance, a Meta Group report states that mainframes won't be able to match the price and performance improvements (close to 35 percent a year) of Intel-based servers, which are emerging with mainframe-like capabilities.
		India missed an era of mainframe and legacy systems due to the absence of global IT majors in the country from the late seventies till the early nineties.

	MAINFRAMES HAVE STAYING POWER (Site not responding. Last check: )
		The operating system on a mainframe was cryptic, requiring a specialized skill set, and it was difficult for ordinary users to get information from the computer.
		Unlike mainframes, client-server systems often come from various suppliers, and the different components may not be integrated or adapted to the company's needs.
		I'd say most people had written them off as a force of change because they were identified with the mainframe and forces of inertia, but they're reinventing themselves very rapidly and learning how to use information technology for the strategic benefit of society.

		Several early mainframe pioneers are expected to gather at the Computer History Museum in Mountain View, Calif., later on Wednesday to celebrate the anniversary.
		IBM is integrating more common parts into its z line of mainframes (which succeeded the S line in 2000), but the series still features a processor not found in other computers, the company's own z/OS operating system, its own file system and a distinct method for formatting hard drives, among other singularities.
		Mainframe hardware can cost nearly twice as much as other high-end systems, he said, and software licensing costs can boost operating costs differences even higher.

		Mainframe users were tied to small "dumb terminals," essentially keyboards and monitors with no capacity to compute or process information.
		These computers were fast compared with the mainframe, which usually was slowed due to the number of users logged on from the individual dumb terminals.

	Report roasts Linux on mainframes \| Tech News on ZDNet
		In a report published this week, Meta Group said that while mainframes running Linux have some advantages in the short term, after two years or so these will become irrelevant as the cost of Intel-based servers continues to drop and their management capabilities improve.
		Mainframes are ideal for consolidation because of their ability to run many different partitions, each with its own operating system.
		Meta Group argues that IBM's mainframes will not be able to match the price/performance improvement of systems based on commodity hardware, which it pegs at about 35 percent a year.

	SWsoft: : Response to Shahin Khan’s “Wolf in Sheep’s Clothing”
		Unlike mainframes, which are designed for large numbers of processors, Sun’s architecture based on SMP results in a significant amount of CPU power to be taken up by memory I/O processing.
		The size of the mainframe’s processor cache is perfectly sized for the mainframe’s processors, as additional cache would have no performance value.
		In addition to the mainframe having higher value, the management and maintenance of 250 Netras is an enormous burden to an organization and increases the Total Cost of Ownership.

		Even with the desktop revolution, the notion that mainframes held at least 80 percent of all corporate data remained intact through the mid-1990s in the minds of many.
		Plus with all the blogs, instant messages, e-mails that do not pass through a mainframe, the amount of data now residing on mainframes is now probably in the neighborhood of 40 to 50 percent,” says Stephen O’Grady, senior analyst at RedMonk.
		Another trend eating away at the mainframe’s dominance is the rise of SANs and NAS appliances.

		The term mainframe was originally coined to refer to the very large computer systems that occupied very large steel framed boxes, and was used to differentiate them from the smaller mini- or micro-computers.
		Although some have used the term "mainframe" to refer to IBM's AS/400 or iSeries systems, this is an improper use of the term; even IBM considers those systems as mid-range servers rather than mainframes.
		Another more humorous definition of a mainframe can be found in Isham Research's Devil's IT Dictionary: "an obsolete device still used by thousands of obsolete companies serving billions of obsolete customers and making huge obsolete profits for their obsolete shareholders.
