How to make deployment quicker with Windows 7 and fog
-
Faster server disk subsystem usually equals faster unicast deployment to multiple clients. I use an old Dell server that has 5 disks in RAID5 array. I can image 15 clients at about 3GB per minute per client, or I can image over 30 tablets that only have 100Mbps interfaces, and get about 900 MiB per minute per client.
When I was using an old desktop with a single 7200 RPM SATA drive it in, imaging more than 2 clients at a time slowed everything down due to the non sequential disk read requests. RAID5 makes it better, as does a RAID controller with built in cache.

Confirmed!!!
I have a FOG machine built out of some old hardware, I used a 7200 rpm disk in them. It images at a decent speed, I wouldn’t say it is slow, it is QUITE the improvement over our WDS choice.
I got a hold of a e-Server IBM machine with RAID5 10K rpm disks. I installed my ubuntu of choice and fog 0.33b and this sucker FLIES compared to my 0.32 server. I’ve also tried installing the Fog 0.32 on this server and it seems it is the hardware that has made the major improvement.
I had some trouble initially setting up the IBM eServer because of the raid control it uses, but once I removed the PCI card, things went swimmingly, not to divert too far from the subject here but I am still working to try to get the PCI card to work incase it has some kind of caching abilities. This use to be a Novell Netware server (which to my understanding is a Linux OS), so I am not sure what I need to do to get the sucker to work right but I’m not giving up yet!

Ok heres my update as to why I had terrible speeds trying to deploy a multicast to 8 workstations. It was because my mobile fog server was plugged into a 8-port 1Gb port switch…which eventually was uplinked to a VOIP phone (100mb) which in return the voip phone was the uplink to the rest of the network…so my fog deployments were severely bottleneck because my fog server was eventually squeezing thru 100mb pipe…by temporarily bypassing the voip uplink and plugging in the 8-port switch to the real network im happily able to say i successfully deployed 8 Windows 7 workstations thru muliticast at 590mb/min which took 52 minutes tops! then i had to image one 6200 and that took 6 mins at 3.39Gb/min.
