In an operation of this scale you're going to have people who basically live in the datacenters, "hands & eyes" support as it's often called. Their jobs range from just going to aisle/rack/position A/B/C and power cycling a box to rack and stack, etc. Some facilities 24x7, some 8x5, some "lights out".
When you have thousands of servers doing something, losing one is generally a nonevent so this isn't really a critical issue. Additionally, the incremental cost of the iLO/DRAC itself, the cabling, the additional cross connect, and the switchport far outweighs the benefits at this kind of scale.

Considering those have a "virtual power button" that accomplishes the same thing as pressing the real one, pretty unlikely unless there is a physical power loss. The management cards also have their own network interface which should be on a separate vlan from the servers themselves. But if worst comes to worst, you can have ip managed power units. So just log into the PDU for the rack and reset the appropriately labeled power receptacle.

Hey chuck? Can you reset server "WEB23871? The iLO/DRAC card failed and caused the server to bluescreen." Now what? :) - Sean On Wed, Oct 14, 2009 at 10:03 AM, Sean Rector <sean.rec...@vaopera.org<mailto:sean.rec...@vaopera.org>> wrote: +1 Sean Rector, MCSE From: Damien Solodow [mailto:damien.solo...@harrison.edu<mailto:damien.solo...@harrison.edu>] Sent: Wednesday, October 14, 2009 1:48 PM To: NT System Admin Issues Subject: RE: A look at the fully-packed racks inside a Facebook data center facility.
