Cisco Nexus

Virtual Device Context (VDC)

The ability to segment one Nexus intomultiple virtual DC Switches.

Overlay Transport Virtualization (OTV)

Creates a layer 2 cloud for switcheddatacenters to span WAN links.

15 Terabit Per Second (Tbps) Architecture

Compatible with upcoming 40 Gbpsand 100 Gbps Ethernet standards.

Cisco Catalyst 6500/4500

Modular Switching

Implements a supervisor engine thatmakes decisions for multiple switch

modules.

Application Specific Integrated Circuits(ASICs)

Perform forwarding decisions at L2and L3.

Enable QoS tagging and access

control.

Cisco UCS

Blade Servers

High density consolidated servers sharingpower and management systems.

Allows for better load balancing and failoverscenarios.

I/O Consolidation

Inter-operable with different network andstorage protocols

Virtual Interface Card (VIC)/Converged NetworkAdapters (CNA)

Enables early detection of network failure

Cisco EtherChannel

Port Aggregation

Enables up to 8ports to share

bandwidth tothe same path.

Enables

additionalfailover for thatnetwork path. Cisco devices support IEEE 802.3ad Link

Aggregation Control Protocol (LACP) and

Cisco Port Aggregation Protocol (PAgP)

I/O Protocols

FibreChannel

Deployed in 90% of SAN implementations.

High speed (up to 16 Gbps), minimal loss

iSCSI

Based on Internet Protocol (IP)

Useful for transport across WAN links.

FibreChannel Over Ethernet (FCoE)

Encapsulates FibreChannel inside ofEthernet.

Allows for higher speeds and greater

Storage Switching

Traditionally dominated by Brocade

Cisco Multilayer Director Switch (MDS)Fabric Switches

Here, LUNs (logical disks) aremapped/zoned from the array to theservers.

Virtualization

What is Virtualization

The process of abstracting OperatingSystems from direct hardware access byadding a layer of specialized drivers

which respond the same way hardwarewould.

Used for server consolidation andresiliency.

Also used to simplify clientadministration.

Dont confuse with simulation or

emulation.

VMware vSphere

Bare-metal hypervisor

Gives virtual operating systems nearly directhardware access for increased performance

and additional features. vCenter administration

Enables vMotion, HA, DRS and other resiliencyfeatures.

MicrosoftHyperV

Theoretically Free

Virtual Operating Systems sit on a fullfledged Windows Server OS.

Uses Windows Server for Management.

Shares many features with VMware

Datacenter in a Box

Virtual Computing Environment (VCE) V-Blocks

Consolidate all of the necessary equipment for

a fully functional virtual datacenter in onenetwork rack with centralized management.

Uses VMware (V), Cisco (C), and EMC (E)technologies.

Notes

TCC offers courses in Cisco, VMware, and(coming soon) EMC.

If you are interested in pursuing

datacenter technology as a career path,lobby the Ambassador, Lauren Steyn, tocontinue to plan field trips/guestspeakers/etc.

I will stick around for questions anddiscussion after the meeting is adjourned.
