Re: Installing an HMC to Existing Systems

Yes, you can manage all three with one HMC. However if they are
geographically dispersed you may get some strange discussion from IBM
regarding that. We have two HMC's for this reason but I often manage the
other site with the local HMC. CE's are getting educated and are quite
content accessing the HMC's remotely. (Especially if you put the keyboard
on the floor in the rack just to make it ergonomically vicious.)

People like Jim and Larry really like to have their HMC's and FSP's on a
private VLAN. Or better yet a physically different LAN. I find that
physically different LAN hard to do when the machines are geographically
dispersed. And I fail to understand why it's ok to have trivial stuff
like payroll and whatnot on the same vlan as all your users but it's
curtains for the free world if the FSP's and HMC's are not separated off.
The way it's been explained to me is that they find hacking into the FSP
pretty easy to do. Maybe because a bulk of accounts use defaults or some
such thing.

Note: HMC's have multiple ports. In Jim and Larry's world they use one
port for you to access the HMC remotely and the other port to put the FSP
on so it's on a separate network.
