From DC 1.0 to DC 3.0
Virtualization
·
Virtual local-area network (VLAN),
virtual storage-area network (VSAN), and virtual device contexts (VDC) help to
segment the LAN, SAN, and network devices instances.
·
Cisco Nexus 1000V virtual switch
for VMware ESX and ESXi help to deliver visibility and policy control for
virtual machines (VM).
·
Flexible networking options with
support for all server form factors and vendors, including support for blade
servers from Cisco, Dell, IBM, and HP with integrated Ethernet and Fibre
Channel switches.
Unified Fabric
·
Fibre Channel over Ethernet (FCoE)
and Internet Small Computer Systems Interface (iSCSI) are two methods for
implementing unified fabric in the data center over 10 Gigabit Ethernet networks.
·
FCoE is supported on VMware
ESX/ESXi vSphere 4.0 and later.
·
The Cisco Catalyst, Cisco Nexus,
and Cisco MDS family of switches all support iSCSI. The Cisco Nexus 5000
support unified fabric lossless operation, which improves the performance of
iSCSI traffic using 10 Gigabit Ethernet.
·
The Cisco Nexus family of switches
was designed to support unified fabric. Currently, the Cisco Nexus 5000 and the
Nexus 4000 supports data center bridging (DCB) and FCoE. However, there are
future plans for the Cisco Nexus 7000 series and the Cisco MDS family of
switches to support FCoE, as well.
·
Converged network adapters (CNA)
run at 10GE and support FCoE. CNAs are available from both Emulex and QLogic.
Additionally, a software stack is available for certain 10GE network interfaces
from Intel.
Unified Computing
·
Cisco Unified Computing System
(UCS) is an innovative next-generation data center platform that converges
computing, network, storage, and virtualization together into one system.
·
Integrates lossless 10GE unified
network fabric with x86 architecture-based servers.
·
Allows for Cisco Virtual Interface
Card to virtualize your network interfaces on your server.
·
Offers Cisco VN-Link
virtualization.
·
Supports Extended Memory
Technology patented by Cisco.
·
Increases productivity with
just-in-time provisioning using service profiles.

Summary of Data
Center
Note: 1 watt = 3.41214 British thermal units (BTU). Many
manufacturers publish kW, kilovolt ampere (kWA), and BTU in their equipment
specifications. Sometimes dividing the BTU value by 3.413 does not equal the
published wattage. Use the manufacturer information if available, if not this
can be a helpful conversion formula to use.

Network Virtualization Design Considerations
Access Control - Ensures users and devices are recognized, classified,
and authorized for entry to their assigned network segments
Path Isolation - Provides independent logical traffic paths
over shared network.(VRF)
Service Edge - Ensures the right services are accessible the
intended users, groups, or devices (FWSM)
