Data & Information
Data stored in files represented as zeros and
ones on storage media with no significance
Content of the file(Os & 1s) transferred
through programs => readable form for
people, then the data => information.
What’re Data centers
A data center or computer centre (also datacenter) is a facility used to
house computer systems and associated components, such as
telecommunications and storage systems. It generally includes redundant or
backup power supplies, redundant data communications connections,
environmental controls (e.g., air conditioning, fire suppression) and security
devices.
Storage Centric IT
Architecture
Storage to the centre of the IT architecture and Server
becomes a appendage device for processing data. (hence
storage centric)
Server problems cease to come into the critical path of data.
Model has connectivity through a separate network for only
storage.
Limitation of having finite no of I/O cards on servers will
become irrelevant & I/F are FC or iSCSI with no limitation
of the length of the cables
Facilitates consolidation of disks or tapes, effective utilization
of disk space as the disks are visible to all
Data center oriented, centralized place, leading to
Reduction in challenges of management and security due to
geographic distribution of Storage and servers by facilitating
common policies for management and security
Reduction in the cost of infrastructure like A/C etc
Cloud & Virtualization
• Virtualization :Abstraction of resources from what is presented to the user (logical form)
different than that of the physical form . Creation of substitutes for real resources, that is
substitutes that have the same functions and external interfaces as their counterparts, but that
differ in attributes, such as size, performance, and cost.
• Virtualization is a technology to create a platform for cloud. Cloud is the vehicle for
services.
• Cloud computing leverages the abstractions of hardware, software, applications, and
storage and networks of the virtualization environment
• After virtualization has been implemented, you still need to standardize and
automate how those virtualized workloads are managed. Combining virtualization
with automating the delivery of those services creates a cloud platform.
• Cloud is elastic and charges only for usage. Virtualization still requires the purchase
of a fixed partition or resource.
• Organizations implementing private clouds need virtualization to ensure that
workloads are well balanced and well managed at the physical level.
