Data Storage Systems
Recording efficiency, data access security, and security of collected information are the basis for choosing the storage and storage system.
Costs for building and maintaining systems should be optimized against the value of stored data. A well-designed system should be scalable and expand as needed in future. Data storage solutions can be divided into several categories:
The task of this class of systems is to copy data for temporary storage (until the next copy is made) to internal or external media, using a specialized set of devices, with dedicated software and procedures and policies. Policies define the organization’s parameters such as protected resources, copy schedules, and rules for storing and retrieving data for business continuity.
The task of this class of systems is to copy data for long-term storage, for high-capacity internal or external media, using a specialized set of devices, with dedicated software and procedures and policies. Policies define the organization’s parameters such as archived assets, copy schedules, and rules for protecting, storing, and retrieving archived data for business continuity.
Systems of this class are optimized for access time and data security, storage systems that store and deliver on-line (very fast disk storage) data collected in file systems, business applications, and database systems. Examples of this class of systems are: SAN (Storage Area Network) – This is a dedicated or campus computer network utilizing special protocols optimized for large amounts of data transfer, providing fast and reliable communication between servers and external or independent storage resources. SANs can be used to connect storage servers (eg disk arrays), servers between themselves, and storage between themselves (for example, non-server backup systems) Network Attached Storage (NAS) – This is a mass storage system that uses fast Ethernet to communicate. The NAS system is an intermediate solution between SANs and classic solutions called Direct Attached Storage (DAS). NAS is a fast and easy way to integrate the existing topology of an enterprise IT network.
Hierarchical Storage Management (HSM) systems, also known as Information Lifecycle Management Systems (ILMs), are optimized for functional and financial security and data security, storage systems that store and share data collected in file systems, business applications, and database systems. The access time to a resource depends on how often it is used on the system. Less used resources are migrated by the system to less expensive, but also slower storage resources.
HIigh Availability systems that perform cloning of IT resources in real time or off-line to obtain the highest level of reliability of computer data, information systems, or production applications in the enterprise. The basic examples of such systems are clustering and data replication.
