Ghost Server

[vallan]

We have a Ghost Server installed on Win2000. We also have it on a Switch set-up of 100MB.

When we do a dump from client of 2GB, it takes over 2 hours. How can I get it to take less. Has anyone experienced this. Does it usually take this long?

Thanks

Mate it should go alot faster than that. Network saturation at the point of tranfer would make a difference though. Have you tried doing this when there are less people ON the network.. at night.

Thanks. On an avergae, how long should it take. And how long should it take if I do it overnight. I am going to image one overnite.

Thanks

Again, doing a load to client of 1.5GB takes 5 mins but doing a dump from client of the same image takes over 2 hrs. we are using high compresion and unicast as it was a one to one. The throughput was not limited.

Any ideas?

Thanks

Timeframe is usually longer but not 2 hours. Up to about 10-15 mins.

What switches do you have? Is the dump going across subnets? Multicasting enabled on the switches?

As above - number of users on the network?

Thanks

We are using a Cisco 6509 and we have multicast enabled. Yes the Ghost server is on a diferent vlan/subnet to the client. What I realised is that multicast is not enabled on the vlan/subnet where the server is. It is enabled on the client vlans. Is this neccessary?.

WHich type of compression will give the fastest time?

Thanks

Also, are they to show different speeds.

On the server it shows a speed of 90MB/min but on the cient it shows a speed of 301mb/min when doing a 'load to client'

Try manually setting your nics to 100/full duplex, and make the same manual setting to the corresponding nodes on the switch. If they're set to auto detect, you may be getting less than optimal performance.

I have used a sniffer and i can see traffic going from the client to the server successfully.

It starts off very high at 150mb/min and within minutes ( like 1 minute) it goes down very swiftly to 50mb/min and then tapers of 8mb/min for the rest after about 5 mins. Is there a buffer, cache or something somewhere.

The client and the server are on the same subnet.

I dont know what else to try. Any ideas?

Do you have "flow control" on your network cards and switches ? Yesterday I was on a new server install where flow control enabled on the some workstations cripled the speed. Might try playing with flow control settings on server and workstations, lastly at the switches, if they are "managed"
