You want to take a look at: |
| 19 |
|
| 20 |
pxebooting |
| 21 |
grub + netbooting |
| 22 |
|
| 23 |
I remember seeing a demo from yamin at a gentoo UK conference demoing |
| 24 |
netbooting with a genkernel kernel |
| 25 |
|
| 26 |
Additionally ipmi would be interesting. ipmi is a standard for remote |
| 27 |
management bioses, many of them are network enabled. At least all dell |
| 28 |
servers have them, Sun hardware has something similar (they invented the |
| 29 |
ipmi standard IIRC) and HP hardware... wel you get the picture. |
| 30 |
|
| 31 |
Most of these BMC-chips allow for remote network control of bios |
| 32 |
settings including power. They are reachable as soon as the server is |
| 33 |
connected to a powersupply (doesn't have to be on) |
| 34 |
|
| 35 |
We've build a system of catalyst, pxe+grub-netbooting + agaffneys |
| 36 |
quick-install + puppet that uses pxe to start bare-metal servers and |
| 37 |
bring up to production config in 45 minutes. We're busy enhancing that |
| 38 |
with ipmi so we never need to go into the datacenter if we hire someone |
| 39 |
to rack the servers. |
| 40 |
|
| 41 |
All servers have a grub config which defaults to normal HD-based booting |
| 42 |
but also have an option to netboot and possible re-install. |
| 43 |
|
| 44 |
So, it's very possible with Gentoo :-) |
