(!) If your environment is 1000+ machines, please contact Acronis Customer Central with a reference to this article. Acronis Professionals will analyze your environment and provide you with ad hoc recommendations.
Common recommendation
It is not recommended to include all of the machines in a single backup plan. Up to 200 machines per backup plan is OK. This recommendation is caused by the high amount of item resolution requests appeared when there are a lot of machines in a single backup plan.
Acronis Management Server databases
Acronis Management Server stores its data in several Microsoft SQL databases and one DML database. The SQL databases are managed by a single instance of Microsoft SQL Server Express (installed by default) or by Microsoft SQL Server (preferred in large environments with 200 machines and more). The DML database is managed by Acronis Management Server itself and stored on the same machine.
SQL Server Hardware
In large environments with 200 machines and more, keep Acronis Management Server and its SQL Server on different machines. SQL Server tends to grow its cache. If its memory usage is not limited, it will allocate most of the server memory.
If Acronis Management Server and SQL Server are on the same machine, limit SQL Server memory usage to keep enough memory for Acronis Management Server and Acronis Management Console (see the next section for the exact values). For information about limiting SQL Server memory usage refer to MSDN: Server Memory Options.
HDD: Acronis Management Server SQL databases take about 20 GB of disk space, but SQL Server log growth should be monitored. To prevent the logs from occupying too much disk space, use Simple Recovery Model or perform regular database backups with log truncation.
SQL Server logs and databases should be placed on different disks for better performance.
RAM: SQL Server needs at least 2 GB of memory for managing Acronis Management Server SQL databases (on the condition that there are no other databases). 1 GB of memory is required for the operating system. If Acronis Management Server reports are often generated, add 4 GB of memory. So the recommended RAM size for the machine is 8 GB.
CPU: SQL Server needs 2-4 cores CPU (4 cores for the case of frequent generation of reports).
Acronis Management Server Hardware
HDD: Acronis Management Server DML database usually occupies 2-4 GB of disk space. It is recommended to reserve about 10 GB for it.
Acronis Management Server DML database file should be stored on a drive with 150 IOPS or higher.
RAM: Memory consumption in large environments tends to be much higher than usual due to lots of objects processed simultaneously: 4 GB for AMS, 1 GB for Acronis Management Server DML database cache, 2 GB for Acronis Management Console. Plus 1 GB for OS results in 8 GB in total.
CPU: CPU with minimum 4 cores is required. CPU with 8 cores is recommended.
