SCM - Answer -supply chain management, manufacturing businesses or companies
like amazon or target might use this
ERP - Answer -enterprise resource planning, allows different parts of the business to
come together
What are the application requirements? - Answer -Capacity, availability, and
performance (CAP)
Why do we prioritize workloads? - Answer -you want to make sure the more important
things are working properly so everything else can work as well
What is an application? - Answer -programs that complete a task, automate a process,
allows employees to work, external or internal facing, and revenue generating
Capacity - Answer -how much information the business process generates over
time+how much it needs to be kept for a certain time, capacity storage
Availibility - Answer -because it is used for business processes it must be available at
all times

resources, materials and HR
Enterprise resource planning (ERP) - Answer -much broader scope than resource
management including manufacturing, SCM, financials, projects, HR, CRM, and data
warehouse
What are the 3 workload requirements? - Answer -capacity, availability, and
performance
Application - Answer -live on hardware, interface of data
,"middleware" - Answer -application and database interact
Database - Answer -backend of application, we do not see this
Operating system - Answer -lives on the hardware
Hardware - Answer -infrastructure, servers, storage, any hardware has an operating
system to make it efficient
Concurrency - Answer -concurrent access (meaning at the same time) to the same
database by multiple users
Security - Answer -security rules determine access rights of users
Integrity - Answer -database structure and rules improve the integrity of the data
Data descriptions - Answer -a data dictionary provides a description of the data
Front end application - Answer -generate the data, generate the workload
Databases - Answer -back end apps manage the data, organize, index, modify, and
access the data
Storage - Answer -storing and protecting data, data is accessible to the end user
through applications
What is a workload? - Answer -the total requests made by a user and application of a
system
What is a "business server" - Answer -a collection of related workloads which allow end
users to complete a specific set of business tasks
How are workloads generated? - Answer -employees enter info into a predefined
application screen
What is a "field"? - Answer -each space that data can be entered into a database
behind the app and not directly accessible by the user
What is a data "write" or "input? - Answer -new data that is being saved or existing data
that is being changed
What is a data "read" or "output"? - Answer -existing data that is being reviewed
What is an IOP? - Answer -input/output per second, measures of storage system
workloads
, Unstructured (file) data - Answer -most difficult and expensive to protect, highest
amount of data redundancy, word, power point
Structured (block) data - Answer -easiest to protect, moderate amount of data
redundancy, database data, phone #s
What are the two types of data? - Answer -unstructured (file) and structured (block)
Active content - Answer -info in the process of being created or is regularly updated,
currently relevant to the business, recent emails, stock prices
Static content - Answer -has not been changed or accessed over a long period of time,
archive data, long term retention
Fixed content - Answer -should not be changed from the moment it is created, can be
active or static, specialized protection
The three types of classified data? - Answer -active, static, and fixed
How to we prioritize workloads? - Answer -immediacy and scope of revenue impact,
impact on ability of customers to interact with customers, ability to recover from
downtime and the associated money, and reputational loss (outward facing)
CPU (central processing unit) - Answer -brains of the computer, conducts
communication between components of the server, "core" = 1 CPU
RAM (random access memory) - Answer -volatile memory where working data is
stored, more RAM generally provides better performance
HDD/SSD (hard disk drive/solid state drive) - Answer -storage for all the data, transfers
only block data
NIC (network interface card) - Answer -controls for external devices such as keyboards,
mouse, and storage devices
Clients - Answer -processing power designed to fit the needs of one user
Server (run applications) - Answer -more powerful, more storage, more CPU, more
nics, more OS functions, better security
Tower - Answer -looks like a desktop, takes up more space than blades or racks,
support closet deployment, could be noisy
Racks - Answer -high density design for installation, compact vertically, space efficient,
requires external cooling and power, most common
