VMware HA environment build 1: Software and Hardware preparations before building

Before writing a virtualization blog post, I would like to thank tim2009, the moderator of the virtualization section of the BKJIA forum. In the virtualization experiment, I will inevitably encounter some technical problems and he will give some advice with patience.

 

I. Lab Topology

Note:

1. the Lenovo general PC on the far left is unable to install ESXI 5.0 because of incompatibility of the NIC. Here we use a HYPER-V to virtualize three servers DC, DB, VC ), if ESXI 5.0 is supported, you can use ESXI5.0 to virtualize three servers. You can also Virtualize two servers. One for domain control DC), the other two data and Virtual Machine Control DB, VC) can be installed on the same virtual server.

2. the ISCSI shared storage server in the middle is recommended to use hardware RAID shared storage in the production environment to ensure data stability and security as well as high exchange rate. In this experiment, we use software ISCSI instead, the 32-bit linux system openflier can be used to build soft iscsi instead of software iscsi, And the 64-bit 2008R2 and 64-bit 2012iscsi can be used to build soft iscsi. In this experiment, 2012 iscsi is used.

3.2 master server HP, DELL) Hard Disks are not installed in shared storage, and each server only installs a 4g usb flash drive to install the ESXI 5.0 system. Each master server has two NICs. if conditions permit the installation of more than one Nic, bind the NIC for greater data exchange.

4. A switch can use two common M switches, or a layer-2 gigabit switch can be used to divide VLAN switches, in this experiment, a two-layer M switch is used instead of an idle M switch. The server's M switching rate is automatically lowered to M, which affects the data switching rate.

Ii. Purpose of the experiment

1. Use two primary servers, HP and DELL, to share 2012 server ISCSI in the same storage)

2. Add two servers with different brands and configurations to a cluster to achieve automatic load balancing and Automatic Fault Tolerance of virtual machines.

For example, if there are two physical servers A and B, create A financial U8 Server 2003-TEST on host A and assign the address 198.1.1.225, during the running process, the power supply of server A is forced to be unplugged. The T3 server is automatically started on server B and provides U8 services about one minute after the service is stopped, for example, if the host location of the 2003-test in the last two images is migrated from ESXI2 to the physical server of ESXI1, the service interruption lasts about 4 seconds in 7 ping responses) the time is about half a minute:

3. After backing up the virtual machine data in the existing cluster, modify the data and restore it to the backup state through the data recovery function.

 

 

Iii. experiment environment

1. For specific hardware configurations in the hardware environment, see the topology)

1.2 master servers for HA high-availability ESXI 5.0)

2.1 PCs are used as auxiliary control environments. 2008r2)

3.1 ordinary PCs for iscsi shared storage 2012 servers)

4.2 common M switches can be replaced by M switches or one M L2 Switch can be used for VLAN replacement)

5. Note: if the above hardware environment is affected, you can use a powerful notebook to virtualize the above hardware environment for this experiment. Generally, the laptop is configured with I5, 8-16 GB memory, and GB hard disk.

2. Software and Images

The CD disk is engraved with the VMWare ESXI 5.0 system installer.

WINDOWS 2008R2-X64 DVD system disk does not need to be engraved with a DVD disk, hard disk installation.

You do not need to engrave the DVD disk on the WINDOWS 2012-X64 DVD system disk.

VMware-viclient-all-5.0.0 Control Software

VMware-VIMSetup-all-5.0.0
