What is a VSM? |
Virtual supervisor module
This is the control software of the Cisco Nexus 1000V distributed virtual switch. It runs on a virtual machine (VM) and is based on Cisco NX-OS software. |
|
|

Virtual Ethernet module
This is the part of Cisco Nexus 1000V that actually switches data traffic. It runs on a VMware ESX 4.0 host. Several VEMs are controlled by one VSM. All the VEMs that form a switch domain should be in the same virtual Data Center as defined by VMware VirtualCenter. |
|
|
How many VEM per 1000v? |
64 |
|
|
People and software are what percentage of the data center cost? |
80% |
|
|
What percentage of nonvirtualized server to data centers usually use? |
5-15% |
|

VNIC |
|
The logical switch sometimes connects to what? |
PNIC |
|
|
What is an access line? |
This is how you configure a vlan for the end point. |
|
|
What is a trunk line? |
This is the point where you connect two switches in a vlan |
|
|
What is the 1100 series switch? |
Server |
|
|
What if you need 65 VEM? |
add two more vsm |
|
|
What are the two types of data center servers? |
|
|
|
What is the chassis or blade server series? |
UCS-B Series |
|
|
What is the rack mount series?

|
|
What is VSG? |
Virtual Security Gateway |
|
|
What are the benefits of the 1100 Series? |
|
|
|
What is vMotion |
The moving from one physical server to another
NOTE: These must be on the same layer 2 domain |
|
|
What is VPC?
|
Similar to Etherchannel
The link is going to 2 devices instead of one and is still able to double the bandwidth |
|
|
What is the difference between VSS and VPC?
|
VSS: Single Control Plane
VPC: Dual Control Plane |
|
|
The 5k and 6k are considered __________ switches? |
Access
NOTE: They will have 2k cabled to them |
|
|
What is FEX
|
Fabric Extender
The fabric extender extends the I/O fabric between the fabric interconnects and the blade-server chassis, enabling a lossless and deterministic Fiber Channel over Ethernet (FCoE) fabric to connect all blades and chassis together. |
|
|
Traditionally what kind of cable connects a normal network to a SAN? |
Fiber |
|
|
What is FCoE |
Fiber Channel over Ethernet
NOTE: allows us to simplify our network |
|
|
What is CAN |
Converged Network Adapter
Runs
|
|
|
Why do you save money with FCoE? |
|
|
|
Does Fiber Channel have to be Fiber Cable? |
No |
|
|
What is Fiber Channel
|
Fibre Channel, or FC |
|
|
What is the size of an Ethernet Packet? |

A vPC switch - one pair |
|
vPC member port |
one of the set of ports (port channels) that form a vPC |
|
vPC peer link |
Link used to synchronize state between vPC peer devices must be 10Gbe
