All of our applications nodes have enough CPU and RAM resources in order to run more than one virtual machine. The initial goal is to virtualize the following HW/Environments:

...

1. node

...

1. :

...

1. Sakai 2.5.x for QA and practice roll out environment. Hardware needed now. We can use smartsite_ng1 and the corresponding RAC instance for smartsite_ng for this environment now. After the roll out, we can return it to the Beta environment usage.
2. node : sakai-dev/test/intg, not needed now (isaac)
3. node : smartsite-beta (provided with Banner data but for users to play with), hardware needed by end of March
4. node

...

1. : most of the supporting scripts, apache to run maintenance pages, ucd-gateway, and ucd-help -- production executables, hardware needed now
2. node : redundant of node 3, hardware needed now
3. node : sakai-beta 2.5.x -- one release ahead of our current release, hardware needed later
4. node

...

1. :

...

1. sakai contrib -- new tools that we don't have in prod yet but we want to evaluate, using stubing for this now
2. node

...

1. : smartsite contrib -- Tools: SCORM and course evaluation, hardware needed now

HW and SW Requirements

• Application Servers
  1. stubing
  2. isaac
• Operation System
  • RedHat v5.1
• Virtualization SW
  • Xen : This is open source
  • VMware
• File System
  • Stored locally
  • SAN and distributed file system such as NetApp or VMFS

Other Information

• Indian Indiana Running VMWare
• Cambridge Running Xen

Database Requirements

• NOTES:
  • Consider versioning schemas, e.g. cm_test_2_4_x_1, cm_test_2_4_x_2, ...

    Schema Names	New Schema Names	Current Machine	Proposed Machine	Comments
    sakai	smartsite_prod	hammer, steele	no change	Production
    sakai_external	cm_prod	hammer, steele	no change	Production
    sakai	smartsite_test	RAC-TEST	Luigi	Smartsite-Test (2.4.x), should be called QA
    sakai_external	cm_test	RAC-TEST	Luigi	Smartsite-Test, should be called QA
    sakai	sakai_dev_1	bricker:devel	bricker	Development environment, host sakai OOTB for schema upgrade diffs
    N/A	Sakai_dev_2	?	bricker	Extra space for internal database only.
    N/A	Sakai_dev_3	?	bricker	Extra space for internal database only.
    sakai_external	cm_dev	bricker:devel	bricker	Development environment, host sakai OOTB for schema upgrade diffs
    sakai_diff	sakai_diff	RAC-TEST	Luigi	used during major upgrades : 2-4-x --> 2-5-x
    *sakai_ng	sakai_ng	RAC-TEST	Luigi	QA smartsite-test 2-5-x.  Use Mario as the app server.
    N/A	sakai_beta	bricker:devel	Luigi	Need new schema since we use bricker:devel
    N/A	smartsite_beta	?	Luigi	provided with Banner data but for users to play with
    N/A	sakai_contrib	?	Luigi	The evaluation of an OOTB contrib Sakai tool.
    N/A	smartsite_contrib	?	Luigi	The evaluation of the Course Evaluation tool, SCORM and other Sakai tools that are adapted to our local environment.
    N/A	smartsite_staging	?	Luigi	Stage ongoing production updates (TAGS)
    N/A	smartsite_fallback	prod	Not required.  Steel is hot spare	Use during database modifications during maintenance upgrades.

*Highest priority

Hardware suggestions:

1. Use Luigi as a database server for all of the above schemas, internal and external.
2. Use Caje for smartsite-test application node.
3. Use Saunder for smartsite-test application node.
4. Use Littlejohn a third application server in the smartsite-test cluster.
5. Use Braddock as the application server for smartsite-beta.
6. Use Mario (ng) for the application server.  Luigi or the RAC can be the database for this.
