Linux Installation Planning

I told you about the zJournal Spotlights before. They're extra editions focusing on specific subjects like CICS, DB2, z/OS, WebSphere etc. You can subscribe to them over here.
Well I just received the 'Linux on System z Spotlight' and I must say it publishes two excellent articles anyone taking up an interest on zLinux should definitely read.
The first one is 'Linux Installation Planning' by Mark Post and it gives a splendid introduction to anyone planning to install his/her first linux on System z. The topics covered :
  • First Things First
  • Pick the Right Architecture
  • Disk Storage Selection
  • Application Selection
  • Application Requirements
  • File System Selection
  • File System Layout
  • Backup and Restore
  • Network Requirements
  • Ongoing System Support
  • Management Tools
  • Data for Installation
The second one is 'Linux on z/VM: Configure for Performance' by Barton Robinson. Starting point is that people may have experience on performance tuning for z/OS or z/VM, but many 'rules of thumb' just don't apply to Linux on System z performance. So you have to reevaluate some of those. The article focuses on three areas : memory, Linux configuration and z/VM configuration. Some topics covered :
  • Configuring Storage
  • Memory Considerations
  • z/VM Storage Architecture Issues
  • Network Storage Impact
  • Minimizing Linux Storage
  • Linux Swap Options
  • How Many Virtual Processors?
As I always say : just check them out !
