Datacenter design

So unified computing will be the UCS line.
Unified Fabric will be the NEXUS line. Fcoe MDS for Fibre and CNA converged adapters
Virtualization is the Vmware/Windows/Citrix Nexus 1000V sits on a vmware  Vlan Vsan

Virtualized Servers on the UCS
Virtual resources.
FC or FCoE  or iSCSI
Vlan or VSAN   Vsan is for Fibre.
and virtualized storage and network. You can have context on firewalls, VSS or VDC


Forces that impact are
Power
Rack Space
Cooling
Management
Security

ILO can help manage servers remotely, you connect to ILO and manage it as if you are there.

Space
Load on the floor
power cooling
cabling  -     blade servers reduce cabling

HVAC  heating ventilation and cooling.

Power
Cooling is the most.

Access
provides ports
Allows for nic teaming and etherchannel
Allows for layer 3

Distribution.
SSL and IPS

GLBP security
place the ROOTs if you must use STP.

Low latency switching

Scalable multicast.


key drivers for virtualization
Cost
reduce device count
Isolate users and traffic
Better performance for price ratio

higher utilization
better uptime


Virtualization network
Vlans   are virtual  broadcast domains on a switch.
Vsan   are virtual on a storage switch like Fibre  MDS
VRF   virtual routing and forwarding   create a virtual forwarding table  (MPLS mainly)
VPN   create virtual networks over the same media
vPC    virtual port channel   this is MLAG on the Nexus 7000 pretends to be one link


Device itself Virtualization.
VM  virtual machines  on the ESX
ACE  context   splits ACE
VSS   virtual switching system on the 6500
ASA  context   split firewalls
VDC   virtual device context.   used on the NExus 7000  pretends to be separate switches entirely.



Access control at the access layer.    classify the users/devices
Path Isolation  like VPN  or VRF   logical separation over the same media
Services split   using the firewall to control the network Vlan to vlan traffic.  control and manage
