If the server has 4 Gigabit Ethernet cards, how would you choose to design a virtual network of VMware platforms?
First, let's look at this virtual network design diagram
Production business network requires the use of independent network segment resources, design is very fixed, it is not discussed
(production, vmotion and management networks can be isolated via VLANs (two tiers), or through routing isolation (layer three)
Vmotion and management A single network card, redundancy and some of the performance is not guaranteed.
VMware recommends the following in ESXi 5.0 's best Practice Practice:
Maintain a vMotion connection on a separate network dedicated to VMotion. In the case of vMotion migration, the internal of the client operating system memory
The volume will be transmitted over this network. By using a VLAN to segment a single physical network, or by using a separate physical network (which is preferred),
can achieve this.
Personally think that even the best practice, but also to use the data to speak, the customer is immoral drop.
Then, in four net card (two card to production) under the premise:
Why Vmotion to a single network segment or network, and management common a network segment or network is feasible?
Do you recommend that the Vmotion Network and management network use the same card?
Scene One
VSwitch0
Vmnic2-management/active-vmotion/active
In the above illustration, the vmotion and management networks can exchange visits, and when we connect vcenter on vmotion virtual machines, we find vsphere client connections vcenter interrupted, due to the Unicast Flooding) unicast flooding, simply said that the core switch 1 MAC Address table contains vmotion and management two information tables, when users connect to use the management IP address, while vmotion is another IP source, The switch breaks the original client session and disconnects the connection.
