[Building Sakai] Supporting files over 2G

[Stephen Marquard]

Hi Hugo,

I'd guess that's fine for student portfolios. We have default quotas of 100M for My Workspace, 200M for project sites, and 1G for course sites. We generally increase quotas on request but don't get a lot of requests to do so.

However, we are seeing increased numbers of requests for large files for media (audio/video) and recently someone wanted to put 3 DVD .iso images online.

Sakai is not necessarily the best platform for audio/video (e.g. a streaming server is better) but it seems reasonable to host .iso images or other large files (e.g. data sets) if necessary.

So the 2G limit seems an arbitrary one given the increases in LAN and Internet bandwidth nowadays.

Regards
Stephen

Hi Stephen,

In our learning environment we consider 100Mbyte enough for students to
build a portfolio. That limit has been established with 20000 students
in mind that might all use that amount of space. (2Tbyte in total)

What is your view on that? And, just curious, for how many students do
you have to cater? 

Cheers Hugo

Hi all,

Having recently tried to upload via DAV a file of around 2.7G, I
discovered that even if you fix an issue in dav which checks the
Content-Length for no real reason, ContentHostingService treats the
content length throughout as an int, as does the ServletResponse API
(c/f http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4187336).

I'm sort of surprised that this 2G limit has been around for so long and
continues to be around. Fixing it is not trivial but not impossible
either. Should we do so, or do we subscribe to Sun's view that "2G is
enough"? :-)

Cheers
Stephen
