To find the values of the “Protocol type” field, look up the possible values of the “Protocol type” field on the IANA website (see Bibliography).

Each of the three main address classes has a default subnet mask that uses the decimal number

Abstract: Reliability is the ability of an apparatus, machine, or system to consistently perform its intended or required function , on demand and without degradation or failure. This paper proposes to increase the reliability of RAID level 5 arrays used for storing archival data. Here, group of two or three identical RAID arrays are considered at the initial stage. Next, a shared parity disk is added to each group containing diagonal parities of their arrays. Now, the new organization can tolerate all double disk failures and between 75 and 89 percent of triple disk failures without incurring any data loss. Two techniques can be used for increasing reliability such as Even-Odd scheme and Row Diagonal Parity (RDP) scheme. This paper gives a study on Even-Odd scheme and Row Diagonal Parity (RDP) scheme for increasing reliability and also proposes a new sparing technique, double parity sparing. Hence forth the proposed scheme provides better reliability as compared to the existing.

The classes were divided into “network groups” which determined how many actual IPv4 addresses were in each group. The chart below best illustrates the network/IPv4 address breakdown (Odom, p. 394):

Level 1 of RAID is called Mirroring. Information or data is stored away twice by writing them to both the mirror drive and data drive. The

A filesystem can refer to an entire storage system or part of an isolated segment of storage, i.e. a disk partition. The word ‘filesystem’ can be used to refer to a partition or disk that is used to store files or as part of the description of the type of filesystem in use. For example, one could say “this is an ‘extended filesystem’” in reference to the type of filesystem in use, or “I have three filesystems” meaning that one has three partitions on which one can store files. (4) There is an incredibly important difference between a disk or partition and the filesystem that it contains. Some programs will operate directly on sectors of a disk or partition, so they could desolate or seriously corrupt any current filesystem. However, most programs operate at the filesystem level, and subsequently will not operate correctly on a disk or partition that either does not contain a

A. It is always better to use materialized views because views are obsolete and materialized views replace them

Click on “OK” so that all information in the drive is erased if the destination drive was already partitioned.

It illustrates the common practices in the enterprise storage array design and trade-offs. It offers improvement in the enterprise storage systems with the random and sequence I/O. It increases the need for the performance to support the enterprise applications. The price of storage capacity comes down regularly. The latency with the rotational speed and seek of the disk access arm have being improved slightly.

Where is a very large, integrated collection of data in a Server, held? Yes, the Storage Spaces. These Storage Spaces lets us combine individual hard disks into storage pools and these can then be managed as a single entity. Storage Spaces is a technology that groups the storage pools and the storage disks which will enable the virtual storage capabilities in Windows and Windows Server (Microsoft Corporation, n.d). The available capacity in the storage pools are then used to create virtual disks which are called storage spaces. Firstly in this paper, I would like to provide an overview of the new Storage Spaces functionality and the Storage Space types in Windows Server 2012. Secondly, I would like to discuss about the fault tolerance and

This is the main storage device which permanently stores the data. The HDD has moving parts and uses them to reach different parts of the stored data.

Even odd scheme consist of simple exclusive-OR computation, A major advantage in this technique is that, it only requires parity hardware, which is already present in the RAID-5 controller, hence it is easy to implement on the RAID-5, without any hardware change. Earlier for the optimal redundant storage, it makes use of Reed-Solomon(RS) scheme. But even-odd is better because the exclusive-OR required here is 50% of the RS scheme.
