Features of SQL virtual server and tips of its using

Virtualization technologies today are used widely, from software development and testing to emergancy recovery and load balancing, virtualization of various applications and other systems. To optimize the work with databases, in the early 70-ies the first version of the SQL programming language was developed. It was created to simplify the interactions between the user and databases. Later on, based on this language, there was developed SQL

Virtualization of servers has become a hot topic lately. Companies providing service and installation of various programs, applications and servers, in almost every order, perform work associated with any kind of virtualization including SQL virtual server.

What is point of using such service?

SQL virtual server is unique in that a potential CPU, disk and memory required hardware installation. This server is one of the few that have the potential to host a significant load on the processor. This is especially important if your application tables associated with volume or more transactions. Therefore, many enterprises and companies choose the launch of SQL Server in a virtual environment.

Memory

SQL installation, as a rule, does not want to allocate RAM. But it minimizes caches by getting OS notifications about the critical amount of memory. The SQL server's resource monitor constantly monitors the memory shortage and starts releasing it until it stops.

Virtual or physical

Most installations of SQL use the potential that is allocated for the server part. SQL processor tends to peak performance is over short periods of time. Servers with quad-core processors and SAS hard drives can provide data rates up to 3 Gbps, it is a quantum leap in the performance of virtual servers.

On one physical server it is possible to install only one SQL application, but at the same time you can create several SQL virtual servers. This will reduce the cost of equipment maintenance, will lead to significant savings on electricity and will allow more efficient use of hardware resources. With such savings and throughputs, a virtual server can compete with the physical in these parameters.
