Data Center Infrastructure
Upon 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

Database
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.

• A customer order is entered via the

• The client accesses the Server over a Local

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

Network
• 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.

Database
• 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.
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 Access
When 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
Security
Data Integrity
Manageability
Capacity
Performance
Scalability
Some Constraints to Meeting the Requirements
Constraints 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
