MODULE 1
DATA
Collection of raw facts
Fiber channel
The fundamental construct of the SAN infrastructure
Disaster Recovery
This is the coordinated process of restoring systems, data, and the infrastructure required to support key ongoing business operations
Cloud computing
The practice of using a network of remote servers hosted on the Internet to store, manage, and process data, rather than a local server or a personal computer.

Risk Triad
IP-SAN
One of the latest evolution in storage architecture and convergence of technologies used in SAN and NAS
Node ports
In fibre channel, devices such as hosts, storage and tape libraries
BC PLANNING LIFE CYCLE
five stages.
1. Establishing objectives
2. Analyzing
3. Designing and developing
4. Implementing
5. Training, testing, assessing, and maintaining
On demand self service
Broad network access
Resource pooling
Rapid elasticity
Measured service
Essential characteristics of cloud computing
performance tuning, data protection, access control, centralized auditing, and meeting compliance requirements.
Storage infrastructure management tools
Data Integrity
Mechanisms such as error correction codes or parity bits which ensure that data is written to disk exactly as it was received
iSCSI
IP-based protocol that establishes and manages connections between storage, hosts, and bridging devices
LAN based backup
All servers are connected to the LAN and all storage devices are directly attached to the storage node.
Bandwidth cost
Security
Proper usability
Migration Cost assessment
Cloud challenges
strategies for administering storage systems on computing devices
ILM
Host
The computers on which these applications run
NAS
IP-based file-sharing device attached to a local area network
Fixed content
e-mail messages
Server, storage, network and virtualization software
Cloud computing infrastructure
assign different categories of data to various types of storage media with the objective of reducing the total cost of storage
Tiered storage
Bus
The collection of paths that facilitates data transmission from one part of a computer to another, such as from the CPU to the memory.
CIFS
Client/server application protocol that enables client programs to make requests for files and services on remote computers over TCP/IP
Offline Archive
The storage device is not directly connected, mounted, or loaded. Manual intervention is required to provide this service before information can be accessed.
Solo gateways between servers and storage
In band virtualization
Lower total cost of ownership
Maintaining compliance
Wider range of options
Simplifed management
Benifits of ILM
