Sharing and Maintaining SLES 11 SP1 Linux
under z/VM using FBA disks DCSSs and an NSS
This paper describes how to install and configure SLES 11 SP1 Linux
under z/VM using Dis-contiguous Saved Segments (DCSSs) and a Named
Saved System (NSS) with the Linux XIP file system option along with
the concept of a read-only root file system. It uses FBA disks rather
than ECKD disks as with the March 2010 paper below.
Linux on IBM System z: Large Discontiguous Saved Segments (DCSS) Under Linux
This document provides results for tests run using large Discontiguous Saved
Segments under
Linux®.
A DCSS is a z/VM technology used to share memory between a number of
guests.
This paper focuses on three areas of application for a large DCSS: sharing
code, sharing readonly
data, and using a DCSS as a swap device.
Sharing and Maintaining SLES 11 Linux
under z/VM using DCSSs and an NSS
This paper describes how to install and configure SLES 11 Linux
under z/VM using Dis-contiguous Saved Segments (DCSSs) and a Named
Saved System (NSS) with the Linux XIP file system option along with
the concept of a read-only root file system. Such an environment offers
the possibility of better performance, improved security, and easier
maintenance of Linux on System z.
