Hi all!
I've recently started to tackle the complex issue of enterprise level netwo=
rk booting and re-imaging for a large number of PC's and Macs en masse. We =
here at Yale have come to the preliminary conclusion that we'll need to con=
figure a virtual LAN that will span all our subnets and layer 2/3 networks =
in order to provide sufficient co-existence for NetBoot and PXE to exist an=
d work (along with isolated multicast). Since our clusters physically co-ex=
ist on networks with other systems we have a particularly difficult set of =
challenges in making this work.
Being that I can't be the first person to have done or attempted this I wan=
ted to reach out and hear about everyone's experiences. Furthermore, if you=
've done this successfully how was your HP/Cisco/Juniper layer 2/3 network =
equipment configured (if at all) to make this work?
Our current plan in a nutshell:
* Isolate all the systems and consolidate them in to between 4-6 subnets ca=
mpus wide
* configure I.P. helpers for the relaying of necessary DHCP/Bootp/PXE broad=
casts
* attempt to isolate routing for multicast (to avoid excessive routing traf=
fic)
Thoughts? Hoping to learn from other's experience :). We are interested in =
hearing your experiences, especially those that dealt with the configuratio=
n of the network to help us understand how others have done this. I've foun=
d good resources on Google, but none point to specific implementations and =
their challenges.
Many thanks, and looking forward to hearing from you!
