Power Blade Network Virtualization Scheme design and specific configuration

IBM BladeCenter is based on the blade architecture, hot-swappable http://www.aliyun.com/zixun/aggregation/13737.html "> Blade servers are plugged into the chassis, each of which is a separate server, Have their own processors, memory, storage, network controllers, operating systems, and applications.

The IBM New generation uses a Power 7 processor blade server with models BladeCenter PS700, PS701 and PS702 Express. The 3 blade servers support the IBM BladeCenter S and H Blade chassis. The PS701 is a 1-way blade, and the processor uses a 8-core Power7 processor (3.0GHZ) with a maximum memory capacity of up to 128GB. PS702 in a single blade operation module to accommodate a total of 2 pieces of host board, is the inclusion of a PS701 blade module, and through the integration of a blade expansion module, so that the PS702 Server Core number of 16 (3.0GHZ), Memory capacity expansion to 256GB.

Compared with minicomputer, power blades have less physical IO resources and integrate BNT network switches as well as SAN switches, and virtualization technology is very different. BCH (Blade Center H's shorthand, same below) knife box integrates two BNT network switches, each with 14 internal port and 6 external port; The storage aspect BCH knife box integrates two brocade SAN switches, each of which also has 14 internal port and 6 external Port, while supporting the Unit Blade (PS701) and the double width blade (PS702), because the blade physical resources are less, so a blade is generally a single VIOS (virtual I/O Server shorthand, the same below) way to achieve PowerVM virtualization, specific VIOS Installation steps, please refer to the relevant documentation, no longer repeat here, the following for the two blades, the detailed configuration for discussion.

single width blade scheme and configuration example

In combination with the above, a PS701 blade has 8 CPUs, up to 128G of RAM, an Ethernet adapter (two ports, connected to up to two BNT network switch modules), and one fiber adapter (two fibre ports, respectively, up and down two BNT network switches). Unit blade As a result of less resources, planning relatively simple, from the network point of view, the two Ethernet port in the main standby way to do EtherChannel, to achieve redundancy, in the virtual Ethernet adapter configured multiple VLANs, while the BNT network switching module configuration Trunk mode.

1. Configure the BNT network switching module on the BCH knife box

If the PS701 blade is located in the first slot of the BCH knife box, then the two Ethernet port (ent0,ent1) of the blade is connected to the first port of the first BNT network switching module of the BCH Knife box and the first port of the second BNT network switching module respectively. Take the first BNT network switching module For example, if the plan is PVID is 1, the blade internal virtual machine need to work and management VLAN is 210,211.

The BNT network switching module supports Cisco's command, typically choosing Cisco's command mode, running commands/boot/prompt ena into Cisco's command mode

Get en permission to start configuring the BNT network switching module:

Enable Configure Terminal

Configure the Switching module hostname:

hostname "SW1"

Configure Port PVID:

Configure PVID to the internal port, according to the foregoing, the PS701 Ethernet port is connected to the BNT network switching module on the internal Port INT1.

interface Port INT1 pvid 1 Exit

Open the Vlan-tagging and pvid-tagging features of the external ports and configure Pvid to EXT1 (external Port EXTX, total 6) as an example

interface Port EXT1 tagging tag-pvid pvid 1 exit

Create VLAN210 and VLAN211, then put the INT1 and external ports of the blades into the planned VLAN

VLAN 210 enable name "VLAN210" member INT1 member EXT1 member EXT2 member EXT3 member EXT4 member EXT5 member EXT6! VLAN 211 Enable name "VLAN211" member INT1 member EXT1 member EXT2 member EXT3 member EXT4 member EXT5 member EXT6!

Taking into account a total of 7 blades, and each BNT network switching module external only 6 port, so the most optimized approach is to make the link of 6 external port, it should be noted that at this time the external switch on the port connected to do link aggregation.

interface Port EXT1 LACP mode active LACP key 15! Interface Port EXT2 LACP mode active LACP key 15! Interface Port EXT3 LACP mode active LACP key 15! Interface Port EXT4 LACP mode active LACP key 15! Interface Port EXT5 LACP mode active LACP key 15! Interface Port EXT6 LACP mode active LACP key 15!

After all configuration is done, save all configurations
