Carrier meets Enterprise

When devices speak a common language a

Early History of Networking — Multiple Users Shared

Computing Resources: User to Device Ratio 1:5 or more

Recent History — All Users had a computer: User to Device Ratio 1:1

Emerging Network — All Users have a computer, IP

Telephone, add to this IP Security Cameras, WiFi Access

Points, Intelligent Building Networks: User to Device Ratio begins to exceed 3:1 10:1

— In excess of three networked devices for each user and growing!

What are the implications of this ratio on our Networks?

becomes an increasing need to control what is done locally

Regulations are driving high levels of data storage

The largest risk to the network are the devices at the

periphery

Cooling Requirements

Higher density means more

heat

Equipment selection and

airflow become critical as

Space becomes a premium

19

Design Stage

Thermal site mapping and

airflow simulators are being

used to design high density

space

Consultants in the Data

Center arena are becoming

more specialized as a result

Again, designs must be

followed to the letter

20

New Products to suit the needs

Equipment racks with

dedicated cooling solutions

are starting be emerge

Density is being addressed

Airflow access becomes

critical

Good Product, Bad Practices

But what happens if poor cable management blocks airflow?

The Data Center Design Dilemma:

Density vs Manageability and Reliability

Fundamentally, you cannot use the same

structured cabling products originally

designed for low density LANs and expect

them to perform to the level required ina

Carrier Data Center

25

Reliability of Data Center Equipment is ye Directly Tied to Proper Cooling

Cables blocking air inlets and exits will raise the temperature of switches and servers lowering their reliability!

Data Center Design Observations

Data Centers are fundamentally different from typical LANs in that they require

Different Architecture Different Level of Reliability

Different Standards

Different Cable Management Needs Different Structured Cabling Solutions

27

Data Center Defined „

¢ A Data Center is dedicated area within a building for

— Reliability and nan —

10 Gigabit Speeds and Higher (copper and fiber)

Storage Area Networks (Massive Hard Drive Arrays

for the long term storage of information)

Key Point: All of the above are very positive trends for our product lines — Why?

29

Blades increase the density of cabling ys

In the data center

¢ Blade Servers, Switches and Clients:

— Increase density of cabling as there are physically more devices per cabinet

— Increase heat generated in cabinet (Airflow becomes more important)

IBM BladeCentere

Bringing the Two Together

Typical Enterprise Data Network

— 99.5% Availability

¢ Typical Carrier Voice Network

—~ 99.999% Availability

¢ Voice, video and storage are real-time applications

- An IP converged network demands that the underlying

network infrastructure must be:

— Delay intolerant, reliable and robust

— Provide for at least 99.999% Availability

— The “five nines” !

from all sources within data center and combines

them onto a small number of high capacity fibers for

transmission to the outside network

Active Equipment — Core Routers (Cisco 12000 or

7000 series), Core Switches (Cisco 6513, 6509), SAN Switch (Cisco 9513)

Passive Equipment — Fiber Distribution Frames (NGF

preferred, FiberGuide and OM3 Cabling)

° Aggregates the data from servers to several fiber

connects that connect back to the Core Router

and/ or Switches in the MDA

- Active Equipment — Aggregation Switches (Cisco

6513, copper and fiber connections)

¢ Passive Equipment — TrueNet Fiber Panel (for fiber fed servers), CopperTen (for copper fed servers’

Another Key Element of the Data Center

SAN Disk Arrays (EMC, IBM, others)

Storage Area Networks (SANs) require ye

a high density of fiber

¢ SAN’s connect a high capacity hard disk

arrays to the data center via Fiberchannel (not Ethernet, yet)

¢ Number of connections demand high density

Network Engineer Concerns within the m Data Center

Scalable

— Density of equipment, cabinets, frames

— Fast and Accurate Moves, Adds, and Changes Thermal

— Problematic in most data centers (designed before Blade Servers)

— Poor Air Flow is the largest concern

Reliability/ Uptime
