[Casper] server performances

[NATHANIEL.LINDLEY at spps.org]

Our main stress is not the imaging part, I've accepted that it will be 
slower b/c file copy instead of block copy for the configuration and not 
being multi-cast.  I have three main servers for imaging reasons.   The 
JSS is Intel 8-core, w/8GB RAM, 3 drive Hardware RAID.   The NetBoot 
server is G5 w.8GB RAM and the Master file share is Intel 8-core/8GB RAM, 
attached to Promise RAID.   So we've divieded up the load for imaging to 3 
servers, all Gigibit with client on 100MB.   (How much is a 48-port 
gigiabit Cisco switch!?!?!?!?!)

We notice that imaging  a couple computers takes about the same amount of 
time as a bunch.  Most we have done is about 20 at a time.  The AFP 
filecopy is limited and the servers never top out. 

Not sure if that helps,  I'm curious to see if we put the Master fileshare 
on a Windows box with ExtremeZ-IP (AFP) or SMB if the performance would 
increase. . .

You do also have to keep in mind the client end, what its specs are, and 
what type of network it is attached to.

You have roughly the same setup as me, I just have more RAM really. I 
don?t serve AFP from my Xserve I actually have SMB from our primary file 
storage for imaging Win as well as Mac on a Windows server attached to 
some SAN.

I wonder what Thomas Larkin does, he has a decent sized deployment, and so 
does Nathaniel, but perhaps they are more distributed.

 Hi ALL, 

 

 As you people seem to have many more servers and clients than me I 
thought you'd be good people to ask about performance. 

 

 I have 145 clients, being increased by 83. 
 

 I have 1 XServe Quad core 2 x 2.8 with 2gb of ram and bonded Ethernet 
ports 
 

 All clients and servers running 10.5.4 and casper 6.01 

 

 I am using AFP for my distribution port and each mac is getting a total 
install of about 60gb (final cut studio) 

 

 I am currently imaging 100 macs and the server is running at 90% cpu and 
100% ram and with a throughput of mac 54MB/sec 

 

 A) is this what i should expect? or is my setup not performing well? 
 

 B) what kind of setup do you people have to deploy how many macs and how 
big a deployment size? 
 

 C) any advice on how to improve my set, more ram, fibre cards, drive 
setups, more servers? 

 

 Regards
