Linux – wakeup on lan support

dell-poweredgelinuxwake-on-lan

I am looking to setup WOL on a set of servers. These are Dell PowerEdge R210 servers running Centos 6.0. I searched the BIOS and I couldnt find the WOL option. My power management in BIOS has only 

i) CPU Power and Performance Management 
ii) Fan Power and Performance management
iii) Memory Power and Performance Management

In linux :

The output of my ethtool eth1 : 

[root@hgcc04 ssubbiah]# ethtool eth1
Settings for eth1:
    Supported ports: [ TP ]
    Supported link modes:   10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
                            1000baseT/Full 
    Supports auto-negotiation: Yes
    Advertised link modes:  10baseT/Half 10baseT/Full 
                            100baseT/Half 100baseT/Full 
                            1000baseT/Full 
    Advertised pause frame use: No
    Advertised auto-negotiation: Yes
    Speed: Unknown!
    Duplex: Half
    Port: Twisted Pair
    PHYAD: 1
    Transceiver: internal
    Auto-negotiation: on
    MDI-X: Unknown
    Supports Wake-on: g
    Wake-on: d
    Link detected: yes

I can enable the Wake-on magic packet by using "ethtool -s eth1 wol g" but still it doesnt seem to work. Can someone please let me know whether my machine has the capability to work with WOL and how to get it to work?

Servers are designed to be powered on 24x7, so it's not surprising that they lack BIOS support for WOL. In instances where you need to be able to programmatically power on a server, I typically use IPMI, via a remote management card. HP provides this through their iLO cards, and I suspect that Dell does via their DRAC cards as well, but I don't have personal experience with them.
