Module 1.3

Data Center InfrastructureUpon completion of this module, you will be able to:• List the five core elements of a Data Center

infrastructure.• Describe the role of each element in

supporting business activities.• Describe the requirements of storage systems

for optimally supporting business activities.• Describe the challenges and activities in

managing the storage systems of a data center.

The Core Elements• Applications• Databases – Database Management System

(DBMS) and the physical and logical storage of data

• Servers/Operating Systems• Networks• Storage Arrays

An Example

Consider an order processing system consisting of:• Application for order entry.• Database Management System (DBMS) to store customer and product

information.• Server/Operating System on which the Application and Database programs

are run.• Networks that provide

– Connectivity between Clients and the Application/Database Server– Connectivity between the Server and the Storage system.

• Storage Array.

An Example ..Closer Look

• A customer order is entered via the Application User Interface on a client

• The client accesses the Server over a Local Area Network.

• A DBMS uses the operating system on the server to read and write this data to the physical location on a disk.

Local AreaNetwork

An Example ..Closer Look

• A DBMS uses the operating system on the server to read and write this data to the physical location on disk.

• A Network provides the communication link between the server and the storage array, and transports the read/write commands and data between the server and the storage array.

• A DBMS uses the operating system on the server to read and write this data to the physical location on disk.

• A Network provides the communication link between the client and the server, and transports the read/write commands and data between the server and the storage array.

• A storage array receives the read/write commands and data from the server and performs the necessary operations to store the data on the physical disks.

Database

An Example.. Optimal Order Processing• The Application should be optimized for fast

interaction with the DBMS.• The tables in the Database should be constructed

with care so that the number of read/write operations can be minimized.

• The Server should have sufficient CPU and memory resources to satisfy Application and DBMS needs.

• The Networks should provide fast communication between Client and Server, as well as Server and Storage Array.

• The Storage Array should service the read/write requests from the Server for optimal performance

An Example.. A Final Look at Data AccessWhen the DBMS receives a request from the

Application:• It first searches the Server memory. If data is found

there, the operation takes, perhaps, a millisecond.• If not, it then uses the Operating System to request

the data from the Storage Array.• Dedicated high speed networks transport this request

to the Storage Array.• Intelligent Storage Arrays can deliver the requested

data within a few milliseconds. They are also typically configured to protect data in the event of drive failures.

Key Requirements of Storage Systems

Availability

Data Integrity Security

Capacity

Scalability

Performance

Manageability

Some Constraints to Meeting the RequirementsConstraints include:• Cost • Physical Environment• Maintenance and Support• Compliance – Regulatory & Legal • Hardware and Software infrastructure• Interoperability and Compatibility

Data Center management activities include:• Provisioning/Capacity/Resource Planning • Monitoring • Reporting

Monitoring• Performance• Security• Data Protection• Utilization

Reporting• Utilization• Performance• Internal Chargeback system for cost recovery

Provisioning• Capacity• Security• Performance

Module SummaryKey points covered in this module:• The five core elements of a Data Center

Infrastructure.• The role of each element in supporting business

activity was explained with an example of an order entry process.

• The importance of an Intelligent Storage Array.• Key requirements of storage systems to support

business activities as well as some of the constraints.• Management activities in a data center operation

with focus on storage systems.
