&Computer / IT industry ::Product Manager (SUSE Linux Enterprise Server) &?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?14::Application Development (better: building the <BR>Linux OS distribution) is the single purpose for <BR>5 years (since 2000). So no change occured in the <BR>last two years. &?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?xxx?14::See comment to question 2). No change in purpose. &- ::&- ::&Main purpose of the mainframe was compile, test,
|
|
<BR>and run.
|
|
<BR>Outstanding usage scenario was virtualization of
|
|
<BR>system resources (disk, cpu, memory, channels) to
|
|
<BR>1) separate (isolate) above workloads
|
|
<BR>2) but share resources (work load balancing)
|
|
<BR>
|
|
<BR>I fact we had only a single machine, however
|
|
<BR>optimized usage would not have been possible
|
|
<BR>without the outstanding virtualization
<BR>capabilities for the zSeries ::&Main purpose is application / Linux OS
<BR>development (and test/QA).
<BR>No external customers are served by this machine
<BR>directly.
<BR>However the Linux OS we produce (SLES 7/8/9 for
<BR>S/390) is used on thousands of instances
<BR>(somewhere between 2.500-5.000) (cannot disclose
<BR>the excat number). ::&No customer transactions.
<BR>2 mainframe supporting internal production.
<BR> ::&?xxx?1?xxx?xxx?xxx?xxx?xxx?xxx?xxx::No IFL (we noeed full sharing of CPU capacity). <BR>No zAAP needed (no java apps). &The machine is exclusivly used for development,
<BR>test and support for the zLinux market segment.
<BR>The formula is cost spend for people, machine,
<BR>support, power and cooled floorspace vs. revenue
<BR>from zLinux generated business.
<BR>Difficult to calculate is the ROI of expertise
<BR>you gain having a mainframe in house (education,
<BR>training, ...) ::&1) Reliability
<BR>2) Virtualization / rescource sharing
<BR> capabilities
<BR>3) IO capability ::&eg.
<BR>http://www.novell.com/success/american_fidelity.html
<BR>
<BR>Demonstrates how large customers value SLES on
<BR>mainframe in their environment (eg. server
<BR>consolidation), also demonstrating intergation of
<BR>other Novell applications to a solution for the
<BR>customer. ::&1) increasing capacity (cpu processing power,
<BR> total avaialble system memory, IO throughput)
<BR>2) execellent QA and service to maintain
<BR> operation ::&IBM is fulfilling this promise, however not
<BR>forgetting to generate revenue from it :) ::&1) ISV/application/solution development on zLinux
<BR> a) Linux has brought a multitude of solutions
<BR> to Z, a range survey (product specific)
<BR> would be interesting
<BR> b) inhouse developement platform: do zSeries
<BR> customers buy or develop or do both ?
<BR> What would be the reasons to buy or
<BR> develop?
