SAN Recovery - Universal Virtual Computer
A Universal Virtual Computer (UVC) is similar to a virtual machine in that it creates a layer between the computer platform and the software and offers portability between different platforms. However, unlike the normal virtual machines, UVC is designed to be universal; it offers a platform independent layer. Thus the [...]
SAN Recovery - Digital Obsolescence
Digital obsolescence refers to a situation when the digital data stored in a digital media is no longer accessible. This situation occurs because either the hardware such as the storage media or the driver, or the software that runs on it is no longer available.
The primary reason for digital obsolescence is [...]
SAN Recovery - Digital Dark Age
Digital Dark Age refers to a possible situation in future when it will be difficult to access old documents stored in electronic media because either the hardware or the software used to access these documents becomes obsolete by then. The problem affects not only text documents but also other digital [...]
SAN Recovery - Enterprise Content Management
Enterprise content management (ECM), according to Association for Information and Image Management (AIIM) International, is the “strategies, methods and tools used to capture, manage, store, preserve, and deliver content and documents related to organizational processes.”
ECM encompasses the legacy problem domains that have been addressed by records management and document management. [...]
RAID Recovery - Nearline Storage
Nearline storage and archiving reduce the load on online systems and result in better performance. However, retrieval of data in nearline storage devices is slower than the SCSI hard disks that are usually connected to servers or are in a storage area network (SAN) environment.
Nearline storage is advantageous since the data [...]
RAID Recovery - Dynamic Random Access Memory
How It Works
If the capacitor charge is more than 50 percent, it is read as 1. If it is below 50 percent, it is read as 0.
The memory cells of DRAM perform a number of other functions too. They identify each row and column by processes called ‘row address [...]
RAID Recovery - Application Programming Interface
Microsoft Windows API
Windows API enables developers to develop programs compatible with Windows operating system and user interface. API eliminates the need to writing the code to create components for OS, such as forms, command buttons and menus. Instead, developers can call these functions in the appropriate Windows API and let [...]
RAID Recovery - Mirror
Mirroring also provides a means to protect contents on a Web site. In case one of the copies is removed from the server, the owner can still use the other one and make multiple copies of it. The best example to demonstrate this is the banning of Google search engine in China [...]
RAID Recovery - Data loss
Data Recovery Services
If data loss occurred due to deletion or corruption in file system, it can be repaired by the user or the system administrator by selecting appropriate software tools. A deleted file is rarely overwritten on the disk, so the file can be restored by reversing the file deletion process [...]
RAID Recovery - Magnetic core memory
Read and Write Process
Reading in magnetic core memory happens when the bit in question attains a ‘0’ status. This is done by driving the selected X and Y lines in the direction that causes the core to flip to the polarity which the machine considers zero. If the core was [...]
