Hello All,
we are proud to announce that Galileo is now using .LRN (2.1a2), our installation is named GES 2 (Galileo Educational System v.2),
so far has been quite stable tag for us, but we needed to do several enhancements in our code to make it scale, and all the improvements are being commited to oacs-5-1 branch.
We migrated from ACES to .LRN, tooks us more tha 72hours the whole process including last minute bug fixing and improvements.
Our .LRN system now has:
16,000 dotlrn-users
4,000 classes
66,540 files stored in the DB (lob)
411,030 items in the content repository
1,727,596 acs_objects
our actual pg DB is about 12GB.
Using aolserver 4.0.7 and postgres 7.4.3 in Debian kernel 2.6.x.
Our hardware configuration is:
DB server, Sauron:
Dell 2650, Dual Xeon 3.06 Ghz 1MB cache
raid 1 SCSI 146GB 10Krpms
(we'll have faster disks soon)
Webserver, Saruman:
Dell 2650, Dual Xeon 3.06 Ghz 1MB cache
raid 1 SCSI 73GB 15Krpms
We will move most of the CR lob files to the file system, which will make the things faster, so anyone that might consider to launch a big installation should store the files directly to the file system instead of PG.
Its integrated to LDAP for authentication of new users, changes on passwords and stuff like that. Also integrating through ims-ent with the university administration system, which help us to map all the users and classes automagically.
Reach the system at ges2.galileo.edu.
Most of the pages are serving at 600ms rate, which is not bad, and some more complex portal pages are about 1200ms which for the most users is acceptable.
Special thanks to all the MIT crew that did a lot of last minute improvements that did this installation of .LRN possible (Tracy, Andrew & Don) and thanks also to all the support from Al and Sloan during this process.
And of course, thanks to the effort of all the Galileo developer crew (GES Team): jopez, quio, paolo, cherry, charly, hector & otto ...
Have a look at some screenshots!
