Novell has announced some discounts for users that want to run its SUSE Linux Enterprise Server (SLES) on a mainframe. Novell already has about 80% of the mainframe Linux market, with Red Hat Enterprise Linux (RHEL) having the other 20%, and so Novell is trying to expand upon its dominance in the area.

With the new Novell pricing, a three-year subscription to SLES on the mainframe will cost what a two-year subscription now costs. And a five-year subscription will cost what a three-year subscription costs now.

There is a catch — isn’t there always? The discounts only apply to users who are coming to Linux on the mainframe through consolidation of distributed servers, or for renewing SUSE Linux on mainframe customers. Although I would guess that probably covers a large chunk of the users who run or would run Linux on the mainframe.

A one-year subscription for patch and upgrade for Novell SUSE on the mainframe is about $12,000. RHEL starts at $15,000 per license per year on the mainframe.

The Novell announcement continues its push on the mainframe. Earlier this year, it came out with a starter kit that lets mainframe users try out SUSE Linux on that platform for free, giving still-skeptical users a chance to try out Linux on big iron.
