Surely one of the main phenomena encountered in the information technology world in recent decades is the exponential increase of the amount data to manage. Various factors have contributed to this phenomenon.
The digitalization of procedures and the need to accelerate company processes to be competitive on the market have led companies to evolve their infrastructure in order to host, manage and especially protect sensitive data. In view of this, the storage infrastructure has evolved in parallel to meet the requirements of high reliability and availability of the data.
But what is storage? What does this word mean that we hear so often in the world of IT?
In general, storage can be defined as a physical device dedicated to containing large amounts of data. There are various types and various models of storage that respond to the diverse needs of each company and its strategic goals. In general, we start from the single server with one or more internal disks (Hard Disk), up to the “Midrange” and “Enterprise” Storage Types, usually accessible by Servers through a Storage Area Network (SAN) or through Network Attached Storage (NAS).
The mechanics available have evolved in time and thanks to new technologies they have arrived at types of discs that can guarantee performance capabilities that can satisfy even applications that are the most demanding and least tolerant of possible latencies.
In addition, to help customers deal with the continuing demand for storage space and optimise the space allocated, new “features” have been developed and refined such as “compression” and “Thin Provisioning” able to slow down the purchase of new space and guarantee the ordinary needs of business procedures.
The protection of data is another aspect that has been brought to everyone’s attention in the field of storage especially in complex environments where there is sensitive data that requires disaster recovery measures. Backup policies, “retention” rules, virtualization solutions are certainly not to be overlooked aspects to appropriately ensure infrastructure reliability and availability of data even when faced with system failures.
In addition to the types of Redundant Array of Independent Disks (RAID) supported by the storage mechanics, further solutions that help complete this scenario of data protection surely include all the functions of Mirroring (Local Protection) and of Replication (Remote Protection) that, when applicable, make the storage Infrastructure ever more reliable and qualitatively first level.
A correct and adequate Disaster Recovery Plan should be considered a “best practice” for companies that invest in complex storage solutions. The market that has developed in this way, provides the opportunity to draw on infrastructures of the Cloud type, as solutions of Replication or Data Backup, operated by leading companies in the sector with costs that tend to fall more and more over time.
Studies estimate that the data growth forecast will be in the order of 4000% over the next 3-5 years! To avoid finding oneself unprepared to face numbers like these is the goal of large companies in the immediate future.
