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.

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

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.
