53
Q

Explain what is meant by Clustering?

A

Means to have multiple pieces of equipment, such as Servers, connected in a manner that appears to the user and the Network as one logical device, providing data and services to the organization.

54
Q

Describe what most traditional data centers use for actual data storage?

A

Traditional Data Centers use a Storage Area Network (SAN), which is a Network that connects individual systems to a centralized bank of mass storage.

55
Q

Discuss the benefits of spine-and-leaf architecture?

A

Reduces the number of necessary devices because every step from the spine to leaf is a single hop - which, reduces latency and creates completely predictable connections.

There’s no concern for Loops, making Spanning Tree Protocol (STP) unneeded.

56
Q

Compare a Storage Area Network (SAN) to Network Attached Storage (NAS)?

A

Network Attached Storage (NAS) is a File based storage where Storage Area Network (SAN) is a Block Level Storage.

NAS tends to be smaller boxes with a bunch of Drives where SAN uses a Fiber Channel, Host Bus Adaptor and relies on very expensive technology to transfer data between a System and the Storage.

57
Q

What are the two types of parties that conduct data center assessments and the benefit of each?

A

External or Internal Parties

External - so there is no preconceptions or bias towards any specific systems, individuals, or their findings.

Internal - has much more familiarity with how data center operations are supposed to work to accomplish the organizational goals.

58
Q

Moving a Server’s Data storage physically apart from the server adds some risk. Describe how SANs addresses this risk?

A

If a SAN Fails, the Server won’t function. SAN solutions provide more than one connection or path between the Server and the SAN, called Multipathing.

If either connection fails, the other connection continues to keep the server connected to the SAN.

59
Q

Discuss the purpose of Jumbo Frames?

A

Jumbo Frames ease some of the cost of moving large amounts of data around the network at standard frame sizes and reduce the total number of frames moving through the Network.

60
Q

Briefly explain the components of a Data Center?

A

Networking Hardware - to secure and effecitvely connect the many Servers to the Internet.
Environemtanl Controls & Physical Security - to protect the Servers and ensure uptime.
Necessary Tools - to protect the data center from catastrophes such as fire and natural disasters.

61
Q

Explain the difference between Access Layer, Distribution Layer, and Core Layer?

A

Access/Edge Layer - The primary connection between the data center connectivity and the users.

Distribution Layer - Provides connectivity between Racks using multilayer Switches and conducts forwarding from the Layer 2 access side to the Layer 3 Core Side.

Core Layer - Ties all the Switches at the Distribution Layer together and acts as the connection point to the external connections, including the Internet.

62
Q

What is the difference between an On-Premises Data Center and a Co-Location Data Center?

A

On-Premises - Dedicated Data Center that is built and hosted ON-SITE.

Co-Location - Public, Third-Party Data Center where anyone could place their own Servers.

63
Q

What happens to a Data Center as the number of Servers begins to grow?

A

Their costs go up!

You need to have a structured approach to organizing your Servers, Switches, and Routers, as well as many support systems (Air Conditioning Systems and Power).

64
Q

List the categories included in a Site Survey Report for a Data Center?

A 
Layout and Space Utilization
Infrastructure INstalled
Expectations for the Organization
Future Requirements
Concerns about Current Performance
65
Q

Describe what most traditional data centers use for actual data storage?

A

Storage Area Networks (SAN), a Network that connects individual systems to a centralized bank of Mass Storage.

66
Q

Briefly explain the benefit of Storage Area Networks (SAN)?

A

Reading and Writing at the Block Level, it avoids the performance costs of implementing its own File System.
The SAN leaves it up to the client computers to implement their own File Systems.
