Enterprise Linux Today: With DB2 Mainframe, Clustering Support, IBM Has Linux Marketing Covered

"Following up on its October announcement of the DB2 for Linux beta and the more recent Telia decision to implement Linux on an IBM mainframe, IBM on Friday delivered a package of DB2 and WebSphere announcements, relating to Linux on both Intel servers and IBM mainframes. These announcements round out a coherent Linux marketing strategy for IBM that is likely to drive Linux adoption, and sales of IBM hardware, into enterprises of all sizes."

"Why would a business like Telia want to run Linux on an IBM mainframe instead of using a large number of cheap Intel servers (or a smaller number of Sun servers), with all the advantages that go along with that strategy? The advantages of using clusters of cheap Intel servers running Linux are fairly well known: low cost to get started, ease of increasing/decreasing capacity by adding/removing servers, and minimal impact on performance when a single server goes down."

"According to Handy, the answer is quite simply that Linux on an IBM mainframe can do the same things better. Obviously, when a few dozen Intel servers will do the job, a mainframe isn't a serious alternative -- there's no way that the cost can be justified. But, when the hardware cost for that "large number of cheap servers" begins to approach the cost of an IBM mainframe, then Linux on the mainframe offers some significant advantages over a collection of separate servers, either Linux on Intel boxes or Solaris on Sun hardware..."

"IBM moved some time ago to port DB2 to Linux and then to port Linux to IBM mainframes. That pretty much covered the technical end of IBM's Linux strategy. With the Small Business Suite and these high-end announcements, IBM has Linux covered on the marketing end with a coherent strategy for getting businesses to start using Linux -- on the low end, the high end, and in the middle."
