We tried Netatalk a while back and with a big environment we had huge 
issues.I am going to test the other though thanks....

Re: [Casper] Using Casper Distribution Points

I've been looking into netatalk (I think) a while ago for a distro point. 
It's open source afp.  Throw that on linux and setup the accounts and you 
should be good to go.

I have only read about it.  I did in previous times use the open source 
protocol for apple talk back in the day when I was tinkering around with 
Linux boxes and it seemed to work OK.

Let us know how it works if you try it.  Seems to be backed by FUSE which 
is an open source project of Google I think.  So it should have decent 
backing and support.

Has anybody tried a NFS share, We were told it wasn't supported but could 
work. We have Several Linux Servers we could use and no free MAC servers

Re: [Casper] Using Casper Distribution Points

Not sure if this helps or not.

We just put in a new Xserve for the JSS. 2 x 2.93 Quad-Core CPU's. 24GB 
RAM. Connected via Gigabit (Link Aggregation between 2 Gigabit ports).

Yesterday we were imaging 30 Intel iMacs with about a 60GB image.  The 
throughput hit about 120MB/s with the average being 80MB/s.  During that 
time CPU utilization sat around 10% (out of 100%).

Point being that, in terms of imaging (with unicast), you are most likely 
going to max out the network throughput before you max out the CPU or RAM.

I'm not sure how it will preform during the school year with all the 
policies, check-ins, and recons happening. (We have around 2500 clients)

I have 5 buildings with about 900 to 1300 laptops in each of them.  Each 
building has both a Mac mini and an Xserve.  The Xserve is the main 
distribution point and also the netboot/imaging server for that building 
since we don't want to image over the WAN. 

We do have Mac Minis in the smaller computer labs and middles schools 
where there are less macs deployed, and they do work fine.  You have to 
load OS X server on them though to get past the 10 client limit of AFP 
connections.

Overall, the Xserves make all the difference.  At first we just had mac 
minis, now that we have both running and load balancing enabled I get 
policy pushed out notably faster.  I also had my boss buy me the most top 
of the line Xserve last year for our JSS and it has 8gigs of RAM in it.

Minis will work, but if you are unicasting policies to 1000s of laptops an 
xserve is much much better.  Plus if you try to netboot/image off a Mac 
mini, forget about it.  You'll be there for days imaging just a few 
machines.  I have not tried multi casting with a Mini though, and I wonder 
how that would work out?

Hope that helps

Tom

Our district is currently beginning the process of migrating our imaging 
and software package need to Casper.   I was wonder if any of the larger 
districts that are using this software have distribution points in the 
schools?   If so what kind of hardware are you using?  Has any one tried 
using the Mac Mini’s?  Thanks for your input.
