[英]Rackspace: Max Server Memory Considerations for SQL Server
I have just adopted a SQL Server 2014 Web Edition instance, hosted on Rackspace; 我刚刚采用了Rackspace上托管的SQL Server 2014 Web Edition实例; my main objective is that I need to improve performance.
我的主要目标是我需要提高绩效。
What screamed out to me is that this server only has 8GB of RAM installed. 让我大叫的是该服务器仅安装了8GB的RAM。 Further to this, max server memory was set to the default of 2TB (2147483647MB).
此外,最大服务器内存设置为默认值2TB(2147483647MB)。 This obviously needs to be brought down to a figure less than the total available RAM.
显然,这需要降低到小于可用总RAM的数字。
Usually, I would provision 4GB RAM solely for the O/S. 通常,我只为操作系统配置4GB RAM。 However, this would be 50% of the RAM.
但是,这将是RAM的50%。
As I am new to Rackspace, I am unsure whether the recommended provision of RAM for non-SQL server processes would be different. 由于我是Rackspace的新手,所以我不确定为非SQL Server进程推荐的RAM设置是否会有所不同。
Any help or comments would be greatly appreciated. 任何帮助或评论将不胜感激。
Many thanks, Stevie 非常感谢Stevie
Rackspace or VM ,below would be the formula to start with,if only SQLServer is running on the box. 如果仅在盒子上运行SQLServer,则下面的Rackspace或VM将是开始的公式。
below is a recommendation from : Glenn Berry 以下是来自的推荐: Glenn Berry
Physical RAM MaxServerMem Setting
2GB 1500
4GB 3200
6GB 4800
8GB 6400
12GB 10000
16GB 13500
24GB 21500
32GB 29000
48GB 44000
64GB 60000
72GB 68000
96GB 92000
128GB 124000
The above recommendation is a good place to start with,if you are not running SSIS,SSRS.. and other things on same box.. 如果您不在同一盒子上运行SSIS,SSRS ..和其他工具,则以上建议是一个不错的起点。
Jonathan Kehiyas recommends to monitor below counters ,even after configuring memory settings here : How much memory does my SQL Server actually need? Jonathan Kehiyas建议即使在这里配置内存设置后,也要监视以下计数器: SQL Server实际需要多少内存?
SQL Server:Buffer Manager\Page Life Expectancy
SQL Server:Buffer Manager\Page reads/sec
Physical Disk\Disk Reads/sec
