How to manage corporate data, has continued to increase at an explosive pace. The background is similar to the following circumstances exist.

The first mentioned is diversification of applications due to the penetration of information systems. In the corporate business systems are in place in response to the needs of a variety of sites, for example, has recently introduced a series of BI tools are intended to strengthen the analysis. Information will inevitably increase if growth should be managed by the system. In addition to text, images and sound, and video, and data to manage its own high-capacity, compliance, in terms of disaster recovery, can now be asked to save data to archive the various have spurred the growth of data.

Masaki Suzuki serve as the IT infrastructure department research director of Gartner Research, Japan, considering the situation, described as follows the trend of the storage market.

"Has led to an increase in corporate data managed by the increase in inter-enterprise cooperation. Has become imperative for companies to strengthen its destination and storage infrastructure, storage market continues rapid expansion seen in the global he "(Mr. Suzuki)

● Storage is not difficult never

Against this backdrop, many information systems professionals, she said that the situation is feeling the pressure to strengthen the foundation for storage. The renovation and expansion of the storage needed for more than a few preliminary surveys in addition to labor costs.

In addition, the technology for storage even if it sees only the typical capacity by assigning more than the actual volume of storage, capacity planning (design capacity) to eliminate the "thin provisioning" and the data finely divided in a fixed or variable size and per-file basis, by reducing the amount of data stored by excluding duplicate data "deduplication", to automatically replicate data to protect data "clone", etc. diverse.

Technical measures to implement its own approach to each vendor, so to emphasize the superiority of their products to focus on technical vendors, and Suzuki have been difficult to understand business users a storage point for be.

So, what's a good starting point on what you choose the best storage companies that match their own. Is to emphasize the need that Mr. Suzuki, "to review the value of the storage aspects of the business" is.

"Use of storage is to protect / save the mission-critical data only. Various features that are provided to enhance the efficiency of storage management. If Toraere Yeah, it is difficult misunderstanding storage should realize that it is "(Mr. Suzuki)

On its first "iSCSI", "NAS (Network Attached Storage)", "unified storage" is to start with understanding the keyword three called Suzuki and he and fastest way to develop the ability to select the optimal storage is emphasis.

● Hold the three keywords should

But what about an overview of each keyword, let's look at step by step.

First, iSCSI first, by encapsulating a TCP / IP packets to a standard SCSI commands and data in the world of storage technology that allows it to connect directly to the IP network storage products. SAN storage has been widely used in mission-critical systems business from the past, consider the transfer characteristics of the storage data bursty high-capacity IP network and the FC's own different (Fiber Channel) comes built on a network other. For, iSCSI does not require a dedicated network storage, has the benefit of dramatically reducing deployment costs.

Also, if the iSCSI storage, and Suzuki is also very easy setting.

"FC has been frequently used in critical-SAN storage system, it is necessary to ask the vendor for configuration changes to a complicated structure, how the time to complete. For, iSCSI storage is a simple mechanism , it can be changed in its setting "(Mr. Suzuki)

NAS is a file sharing service that provides storage for the client PC, a dedicated computer and said service files from the hard disk controller is configured with the OS. Its characteristics are also highly functional and say nothing. Product has many rich features such as deduplication and thin provisioning, ease of use is very high. Choices are still valid and said advancing the operational efficiency and capacity.

Unified storage, FC and NAS-based storage but support multiple interfaces such as a SAN.
