SANs Vs. Traditional File Servers

One other thing that I haven't seen mentioned yet.....are all the drives hot-swappable? If not then when a drive dies (and trust me, they WILL! =)) you'll have to shut down the machine, crack the case, and replace it. I'm just assuming that with 2TB of data that isn't something you would like...

Gigabit NICs

One machine is a RAID0, the other is a Seagate X15-36LP 15k scsi drive, so throughput should be pretty good. I'm also using throuput testing programs as opposed to copying files and timing it. I still think it's a nic issue. Thanks for the comments.

Gigabit NICs

I should have given more info! Currently the nics are in my home machines (each is a 1.7Ghz machine) and I have been using netcps to test. It maxes out at 20MB/sec which works out to be somewhere around 160Mbps. File transfers using windows give about the same results. I've run them through...

3Com NICs gone Wild

Are you using load balancing software or anything? Cause if you just plug 2 nics in you're gonna have a big traffic mess because your computer will effectively have 2 MAC addresses and computers will not know how to communicate with it. Unplug one and things should work right.

Bandwidth 4912g

The Cisco 4912G has 12 GBIC ports and has "24 Gbps of dedicated bandwidth" according to the Cisco site. This is not a modular switch, so you would not be able to change that.

10/100 Switch issues

The stacking ports usually combine the switches backplanes, so instead of 2-24 port units, you would have 1-48 port unit. In this situation you would only have 1 uplink to the core (unless you're doing a trunk), which would mean that the stack would have just the one link for 48 ports vs the...

10/100 Switch issues

I'd check duplex settings. Sometimes ports set to autodetect don't "sync" up correctly and can cause the network to run very slowly. Try forcing the port and the nic to 100 full duplex and try the speed again. Also, what kind of gigabit core switch do you have? Possibly the Dell 5012?? I'd...

Have you added in the forwarders so that the server knows where to resolved a query if it cannot do it locally? Under the properties of your server you should have a forwarders tab. Put the dns server of your ISP in there and you should be good to go.

To run AD you MUST have a DNS server running, and it must support dynamic update. Concentrate on getting your 2k server w/AD installed and working right before you attempt to setup Exchange.

MS Exchange Server

Are you trying to install Exchange 2000? If so, then you need Active Directory. I'd highly recommend against running AD AND Exchange 2k on the same box. They both use quite a few resources especially if you've got a fairly large network.
