iDRAC and interface IP address planning

The Chassis Management Controller (CMC) must be assigned an IP address first, so that you can communicate with the chassis. This gives you Web-based access to the CMC, as shown in this section.

Reserve at least 64 consecutive IP addresses for communication with a single X10G chassis and all of its blade servers.

Most sites use a pattern similar to this: xxx.xxx.xxx.100 for the IP address of the CMC; xxx.xxx.xxx.101 for the Integrated DELL Remote Access console (iDRAC) for the blade in slot 1; xxx.xxx.xxx.102 for the iDRAC of the blade in slot 2; and so on. After the CMC has an IP address assigned, you use a Web interface to assign iDRAC IP addresses to all 16 slots as a range. All slots (even empty ones) will have an iDRAC address.

Chassis location	IP address example
CMC	xxx.xxx.xxx.100
Slot 1 Integrated Dell Remote Access Console (iDRAC)	xxx.xxx.xxx.101
Slot 2 iDRAC	xxx.xxx.xxx.102.
Slot 3 iDRAC	xxx.xxx.xxx.103
Slot 4 iDRAC	xxx.xxx.xxx.104
Slot 5 iDRAC	xxx.xxx.xxx.105
Slots 6 through 15	consecutive IP addresses
Slot 16 iDRAC	xxx.xxx.xxx.116

Plan to have a sequential range of IP addresses reserved for the interfaces you plan to use on every blade server as well (such as C, A1.P1, and possibly A1.P2).

For example:

IP address of CMC might be: 010.008.000.100

IP address range (remote access) for16 blade iDRACs: 010.008.000.101 - 010.008.000.116

Subnet mask: 255.255.000.000

Gateway IP address: 010.008.000.001

The C interfaces (typically interface C connects to the Internet) on the 16 blades might use this IP address range: 010.008.010.201 through 010.008.010.216

The A1.P1 proxy interface on the 16 blades might use IP address range: 010.014.000.100 through 010.014.000.116

IP address of on-chassis switch A1 might be: 010.015.000.121

IP address of on-chassis switch A2 might be: 010.015.000.122
