SLES9 64 bit with OSA (OSA and Hipersockets have large buffer requirements) say they need 512MB. I've done installs in 256 MBs. I do get a message stating insufficient storage, but the install with only the normal base packages, works fine.
During the installation, you don't have access to Linux swap disks. A Linux virtual disk is carved out of the storage you have, and the initial load/creation of a Linux system is done in memory. Then that system is, in effect, booted, and now a system is built on disk. Depending on what your options are, you will use different abouts of virtual disk. If you run out, your installation will fail (just looks like it stops at a point where it may be thinking about something....never comes back). If this is your first zLinux installation, then use their suggestions. No use throwing in a monkey wrench in to the works. Once you get use to zLinux installs, you can try things out. If you will be installing a memory intensive product (a database), you may want to plan for that memory, before you install. AND, it is easier to get better database performance, right out of the box, if, when you install the database, you give it the memory you will be running in. Some databases, at installation time, looks at the memory you have, and customizes certain memory related parms. A good DBA would know these and change them, but for the rest of us<G>.... Linux was designed for the "fixed hardware crowd", that is PC, Servers, etc. You have non shared hardware dedicated to it. On the mainframe, a shared platform, we try to find "best use" for our resources. If you don't really need a GB of real memory, we will trim you down to give the memory to some other deserving system. Sure you may swap more, but we have one kick-a@@ I/O subsystem. To a point, we will trade more I/Os for less real memory requirements (kind of backwards from normal mainframe thinking).
