We are moving our servers to a new DC and I am looking for a bit of advice with our new COLO setup.

I have some knowledge of networking but I am an enthusiast more than anything so it gets a bit confusing.

The current setup we have is:

2 x DC network feed to my 1/4 rack

2 x CISCO PIX 515E Firewalls - FW1 and FW2

1 x HP Procurve 1800-24G Switches - SW1 and SW2

2 x DELL PE2950's running ESXi hosts - VS1 and VS2


The two network feeds go to our redundant firewalls, and they work in an active-passive way, one kicks in if the other goes down.

Our new DC wants to charge extra for 2 network feeds (only one as standard) and we also have some new kit to improve redundancy further.

We now have:

1 (possibly two if best) x DC network feed to my 1/4 rack

1 x APC7920 remote reboot switch

2 x CISCO PIX 515E Firewalls - FW1 and FW2

2 x HP Procurve 1800-24G Switches (layer 2) - SW1 and SW2

2 x DELL PE2950's running ESXi hosts (both with 2 teamable NICs) - VS1 and VS2

What were looking to do is:

  • make the switches redundant
  • incorporate the APC reboot which needs a network link
  • possibly use vLans to:
    • isolate the management of VS1 and VS2
    • prioritise traffic to VMs
    • Allow fast backups from VS1 to VS2 (pref not via firewalls)

I don't think its possible to set this up properly without 2 network feeds from DC, but any advice on configuring this new setup would be appreciated (with details if possible).

Thanks in advance.
