Q.1 State the various reasons for data lossin some businesscorporations.
Answer: Risk is a measure of potential economic loss, lack of return on an investment or asset, or
material injury.Anotherwaytostate thisis that riskisa measure of exposure toharm.
The Effectof Lost Data on BusinessOperations
Companies recognize that data loss represents a business risk. Even if a monetary value is not assigned
to the data, the negative effects on operations can be significant. In many cases, corporate operations
can be so adversely affected that companies feel the need to mention the risk in regulatory filings and
shareholderreports.
Q.2 How ILM supports implementationofregulatory concerns?Explainwith an example.
Answer: Informatica ILM Nearline is highly scalable, high-performance software that empowers IT
organizations to cost-effectively manage the explosion of data growth in their SAP BW systems. The
software enables IT teams to easily and safely move infrequently-accessed data from SAP BW into an
integrated nearline data store. Nearlined data can then be accessed seamlessly from the SAP BW
interface using the same access methods that were used when the data was still in production. By
reducingthe size of the productiondatabase,

2. Q.3 Describe the two product classesin storage networking.
Answer: Storage networking is the practice of linking together storage devices and connecting them to
other IT networks. Storage networks provide a centralized repository for digital data that can be
accessed by many users, and they use high-speed connections to provide fast performance. It's most
common to find storage networks in enterprise settings, although some vendors do sell networked
storage products for consumers and small businesses. The phrase "storage networking" is commonly
usedinreference tostorage areanetworks(SANs).A
Q.4 BrieflyexplainredundantI/O path elements.
Answer: Multipath I/O (MPIO) is a Microsoft framework designed to mitigate the effects of a host bus
adapter (HBA) failure by providing an alternate data path between storage devices and a Windows
operating system. MPIO enables up to 32 alternate paths to add redundancy and load balancing for
Windowsstorage environments.
Pathing is a networking approach used to address the specific needs of storage networks by changing
the way that communication paths are managed and organized. Unlike connection failures in message
networks -- which generally just require that the connection be retried -- in storage networks, a failure is
more likelytocause a systemcrash.Storage
Q. 5 Describe file systemhierarchy and parsing the file system.
Answer: The File system Hierarchy Standard (FHS) defined the directory structure and directory contents
in Unixand Unix-like operating systems. It is maintained by the Linux Foundation. The latest version is
3.0, released on 3 June 2015. Currently it is only used by Linux distributions. A File System defines a
logical way to read and write information. In this way, it can be considered a specification. Most PC file
systemsare basedoff of the desktopconceptof filesandfolders.
There are alot of different kinds of file systems. Some are widely use (Like FAT12, FAT16, FAT32, NTFS,
ext (Linux), HFS (Used in older MACs); other file systems are only used by specific companies for in
house use (Like the GFS - Google File System). Some file systems are used in networking only (NFS). You
