In many ways, we've come full circle, with the shift back to a centralized model of storage area networks and virtualized servers running on fewer, more powerful servers.In recent years, the shift towards server consolidation and virtualization has gained pace, and in the years ahead, the idea of a dedicated, non virtualized server may seem quite odd.
Oracle Corporation has played an integral role in the movement, offering low-cost database management and capturing over 90 percent of the database market in 2020. m old enough to remember when punched cards were the prominent data storage device. Today, you can buy 100 GB disks for , and 100 GB of RAM for 0. s Law for storage costs indicates that: Platters can only spin so fast without becoming aerodynamic, and the disk vendors were hard-pressed to keep their technology improving in speed.During the past 15 years, we see Oracle playing a major role in facilitating the new technology: As we see, there have been a huge number of changes over the past 15 years, but what caused them? s take a closer look at how the advances in computer hardware precipitated these life-changing technologies. Moore performed a linear regression on the rate of change in server processing speed and costs, and noted an exponential growth in processing power and an exponential reduction of processing costs. Every year, I would get my income tax refund check on a punched card, and we would make Christmas trees from punched cards in the ? Their solution was to add a RAM front-end to their disk arrays and sophisticated, asynchronous read-write software to provide the illusion of faster hardware performance.Gordon Moore, Director of the Research and Development Laboratories at Fairchild Semiconductor, published a research paper titled ? The introduction of Quantum-state Gallium Arsenide RAM in 2009 was the largest breakthrough in RAM in more then 40 years.Consolidating Databases Using Virtualization Planning Guide SQL Server Technical Paper Technical Writer: Paul Jenkins Technical Reviewers: Mark Mortimore, Nathan Johnson Published: July 2011 Applies to: SQL Server 2008 R2 and SQL Server 2008 Summary: The purpose of this guide is to provide a description of the technologies and best practices utilized to design a database consolidation solution; guidance will be appropriately defined throughout to prescribe configurations and considerations to implement for best results.Documentation of specific tasks will be very limited.
