if i were you i would set up ip routing on the 2 core switches and just route between the 2 and on core 1 have a route out to the internet via core 2.
this would also stop any broadcast traffic going over the site link. i would also have a DHCP server at each site for redundancy / failover, DHCP doesn't need to run on anything powerful, an old pc with a free linux distro or 2003 would be fine.
if you need to add an ip helper address it is very simple,
ssh into the swtich >> enter config mode >> type vlan 10 (id of vlan) >> type ip helper-address 172.16.1.1 (ip of dhcp server)
if all is working remember to write the memory else next time the switch reboots the new config will be lost
Cheers, worth a thought. Would prefer to keep DHCP on something we can easily belt with a slipper though DNS is already running on both sites, not sure why DHCP never was but that can be easily sorted. For the IP helper, I assume we'd just need to do that for each switch - so for Site 1 switch the IP Helper should point to the Site 1 DHCP server and Site 2 should point to Site 2 DHCP Server? (May sound obvious but would like to get this right first time )
A separate web cache on your other site would help too.
As said, we need to make as few real changes as possible. That time will come in the summer. As easy as setting up another forefront server would be for the cache is, we could do without raising the amount of servers (physical or virtual).
Will keep plodding on with the 2 vlans I think for the time being.
No worries - yes it is needed to improve the network but we need to have 0 downtime (grumbles at not being allowed in after 16th Dec) and leave major changes until late July. We just need to make sure it ticks over until then.
Ģ2600 a piece. PM sent for where.
@synaesthesia - Could you PM me? - that's a crazy price...
That's the 5406zl+44G+4SFP+POE.
Did you get the Premium Software with it?
I Paid 3k for 5406zl+44G+4SFP+POE with an extra power supply for the base. We then got 2 Fiber Switch Modules, 36 Gbics.
Then about a month ago I purchased a 24 port Copper Module from @Millgate

Indeed Millgate do offer good pricing for the individual modules (that's where the expense comes in with these switches). We don't need that functionality yet but of course the whole idea of the switch setup is to be able to add to it.
We didn't worry about the premium software as from everything I read that equates to the Procurve Manager 3.2 software which is free to download for procurve users anyway. I had actually assumed it meant the PCM+ software which is a good couple of thousand to buy on it's own but that's not necessary for us, PCM on it's own handles our switches and the Dlinks just fine.
Take a look at the firmware, Its size is currently over 10MB, yes thatīs MegaByte.
Update: Sorry, havenīt read the rest of your topic. Keep your 5400zl for your core and please donīt take the latest K.15 software, yet. Stay with K.14 for now...
