Our suggested minimum hardware configuration is based on experience and testing for both client and server platforms. These configurations are only suggestions and are not meant to imply that older or slower machines are not usable.
Systems with less memory, smaller hard disks, or systems that are generally slower, may have acceptable performance for basic operations. These systems may also be acceptable when not called upon to operate simultaneous tasks that require hardware or network resources. Memory-intensive applications may require additional memory for proper performance. Examples of these optional or advanced features of the Metasys system include navigation and support for complex graphics, operation with the maximum number of users, complex and extended queries with the Metasys Export Utility, support for large network integrations, and large numbers of concurrent open windows.
When deciding on computer hardware, consider the following important factors:
- Overall system performance is highly dependent on the total amount of available computer RAM. If you experience performance issues with the ADS or ADX, increase the total amount of RAM.
- For improved performance, consider Serial Attached SCSI (SAS) hard drives over Serial AT Attachment (SATA) hard drives.
- Be sure to enable the write cache feature on the disk controller.
- Dell and HP are the preferred computer manufacturers. They offer machines that match the hardware recommendations listed in this document.
- Do not enable power saving modes on the ADS or ADX computer. Such modes automatically turn off disk drives and network cards, thereby adversely affecting proper Metasys system operation.
- Remember to obtain Windows operating system Client Access Licenses (CALs) for the total number of users and devices on your system. Refer to the Network and IT Guidance Technical Bulletin (LIT-12011279) for more information on CALs.
