## Minimal hardware configuration

The Service Virtualization Server and Service Virtualization Designer can run on any hardware configuration that is using a supported operating system and has at least 1GB of physical memory installed and available for each product.

With the minimal hardware configuration, you can perform all functional testing scenarios and some basic performance testing scenarios, provided that they do not create too much load on virtualized services.

## Recommended hardware configuration

Virtualization hardware sizing is complicated and may include many factors. For detailed sizing recommendations, contact Customer Support.

The following hardware configurations provide a good performance balance for normal usage scenarios, where each product is installed on a separate machine.

Service Virtualization Designer | Intel® Core™ i3-10110U @ 2.1GHz or similar 4GB physical memory Free physical disk storage space: The Designer typically uses less than 2 GB of space for installation and all Service Virtualization projects, as follows: 850 MB for the Designer installation 10 MB for each service, where this figure can grow as recorded traffic increases An additional 1 GB should be available for MSSQL Express, if installed locally Use the following calculation to calculate your required size: 15*MSG_SIZE*MSG_COUNT where: MSG_SIZE = learned message size in kilobytes MSG_COUNT = the number of unique messages learned during the learning process
Service Virtualization Server | Intel® Xeon® E-2134 @ 3.50GHz or similar 8GB physical memory Free physical disk storage space: 650 MB for the Server installation. The Server maintains some data on the local disk such as log files, configuration files, and generated SSL certificates. The rest of the data including virtual services are stored on the Database Server.
Database server | Intel® Xeon® E-2134 @ 3.50GHz or similar 8GB physical memory Database storage: The database typically requires 1GB of disk space, but this figure can grow as recorded traffic increases. Use the following calculation to calculate your required size: 30*MSG_SIZE*MSG_COUNT where: MSG_SIZE = learned message size in kilobytes MSG_COUNT = the number of unique messages learned during the learning process
