In computing, enterprise storage〔(【引用サイトリンク】title= What is Storage )〕 is the computer data storage designed for large-scale, high-technology environments of modern enterprises. In contrast to consumer storage, it has higher scalability, higher reliability, better fault tolerance, and a much higher initial price. From the salesperson's point of view, the four main enterprise storage markets are: * Online storage - large disk array solutions, minimizing access time to the data, and maximizing reliability; * Backup - off-line storage for data protection, with a smaller price per byte than online storage, but at a cost of higher average access time; often uses sequential access storage, such as tape libraries; * Archiving - technically similar to backup, but its purpose is long-term retention, management, and discovery of fixed-content data to meet regulatory compliance, litigation protection, and storage cost optimization objectives; * Disaster recovery solutions, used to protect the data from localized disasters, usually being a vital part of broader business continuity plan. The enterprise storage industry includes conferences,〔(Storage Decisions )〕〔(Storage Networking World )〕 publications,〔(Storage Magazine )〕〔(InfoStor )〕 and companies (3PAR, Atempo, Fujitsu, Iron Mountain, Isilon, EMC, DELL, HP, Hitachi Data Systems, IBM, Microsoft, NetApp, Novell, Open-E, Pillar Data Systems, Sun Microsystems, Syneto Storage, Symantec/Veritas Software, WhipTail, SuperMicro etc.). A common expectation is that hard disk drives designed for server use will fail less frequently than consumer-grade drives usually used in desktop computers. A study by Carnegie Mellon University and an independent one by Google both found that the "grade" of a drive does not relate to the drive's failure rate. A 2013 criticism piece remarks that: Large enterprise and corporations demand high quality storage medium that has enough memory storage to hold all of the businesses data, in addition to high reliability due to the importance of data in a large scale organisation. It is these key features that differentiate enterprise storage from consumer storage, and is the reason for why it tends to be considerably more costly than consumer storage due to the quality in storage required. Larger organisations also need to consider the legal requirements of holding key data about customers or clients and will need to oblige to the Data Protection Act. In addition some government legislations such as the Sarbanes Oxley Act require businesses to ensure that they are backing up data regularly, not doing so may result in data being deleted. This further highlights the need for organisations to hold powerful and reliable storage mediums in order to adhere to these laws and legislations. == Hard drive storage medium == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「enterprise storage」の詳細全文を読む スポンサード リンク
