Presentation Not sponsored by the Government Not connected with the Government Not endorsed by the Government This is purely presented as a hobbyist.
5
The Mainframe Must Die! Perceptions of the Mainframe Words Hurt Expensive Huge Dinosaur zSeries Servers Enterprise Scalable Velociraptor
6
zSeries Server Vocabulary LPAR FICON and FCP DASD Cryptography Accelerator z/VM 64bit Operation IFL Books
7
LPAR Hypervisor Virtualized Systems Physically Unconnected Hipersockets 60 LPARS Memory Isolation Variable Workload
8
FICON and FCP Both 4-8G 1600 MBps Fiber Connectivity Multiple Concurrent Additional CRC Same Cables as FCP Fiber Channel Protocol Switched Fabric SCSI
9
DASD zLinux uses Direct Access Storage Device ● CKD Count Key Data ● FBA Fixed Block Architecture FCP ● SAN ● NAS ● SCSI
10
Cryptography Accelerator Off-loads Cryptography Processing 128 bit AES DES SHA Independent Random Number Generator
11
z/VM Hypervisor Monitoring Tunable Isolated Memory Hipersockets
12
64bit Operation 31 bits? 64 bits?
13
IFL Integrated Facility for Linux Tuned to Only Linux Processor Instructions 256 Theoretical guests.
14
Books Processors and Memory are in “Books” Hot Swappable Add Processors Hot Add Memory Hot
15
z/Linux Is It Really Linux? Distributions Configurations Strengths Weaknesses Well Suited For Who uses it? How Do I do it?
16
Is It Really Linux Not Emulated Complete Native Operating System Formally Released 2000 Linas Vepstas Big-Foot, Think Blue Open Source Gartner Reports the Future of Government and Big Business Makes IBM OSS friendly
17
Distributions Red Hat RHEL6 Novell SuSE SLES 11 Debian Gentoo Slackware CentOS Fedora Etc
18
Configurations Just Like Real Linux Multiple Network Interfaces Logical Volume Management (Grow on the Fly!) RPM, APT-GET, YUM, YAST and Source LAMP Oracle, DB2, MySQL PHP, Perl, JBoss, Java, Ruby (This list goes on)
19
Strengths Costs (Most Important) Enterprise Class High Availability Standard Development High I/O Industry Direction Security Support Ubiquity
20
Weaknesses Processor Intensive Package Availability z/VM Knowledge
21
Well Suited LAMP Applications CMS (Content Management System) ● Wiki (Mediawiki, Twiki, Swiki…..) ● Blogs (WordPress…..) ● CMS (Drupal, Openpublic, Joomla, OpenPublish….) Databases MySQL, Oracle, DB2, Postgress …… Email Sendmail, Postfix…. Security Scanning (Nessus, Satan, Sara… Firewall – IPTables So Many Others
22
Who Uses z/Linux? CMS Center for Medicade/Medicare Services NIH National Institutes of Health SSA Social Security Administration State Farm Many others
23
How Do I Do it? There is plenty of help on the internet. Detailed instructions may be found http://www.turbohercules.com/projects/zlinux/ http://linuxvm.org/info/howtos/hercules.html Support may be found at http://www.turbohercules.com/services/ http://www.hercules-390.org/
