      ggRock Hardware Selection Guide

      This article is meant as a guide to appropriately select hardware for a ggRock server based on center needs.

      If you're inundated with all this information don't worry, we're here to assist!

      Reach out to us at sales@ggcircuit.com

      We'll be more than happy to discuss how we can help ease some of the burden from your shoulders through our server configuration and on-site services. 

      General Notes

      Running ggRock in a virtual environment is not supported.

      All hardware selections should be enterprise-grade or server-grade, not consumer-grade.

      All hardware selections should meet or exceed the listed minimum specifications.

      Power Supply

      It is advisable to have redundant PSUs.

      Power requirements depend on the hardware being used.

      Cooling Fans
      As needed dependent upon cooling needs and space restrictions

      Network Card⁴
      10G SFP+ or better 25G SFP+ or better 40G QSFP+ or better

       

       

      CPU Notes:

      The selected CPU should be a server-grade CPU such as an Intel Xeon Bronze or better or AMD EPYC or better because they support ECC RAM which is critical to system stability.

      Prioritize more cores or higher thread count over CPU frequency.

      RAM Notes:

      To ensure data integrity, only ECC memory should be used.

      Drive Notes:

      QLC drives should be avoided, as well as any drive with a decreased cache size (e.g. Samsung QVO) which severely impacts performance.

      Hardware RAID controllers, if used, must provide direct access to the operating system to the individual drives (e.g. HBA mode or pass-thru mode).

      PLP (power loss prevention) drives can, optionally, be used to protect further against data loss or corruption on power failure.

      Network Notes:
      SFP+ Recommended

      Server NIC must be compatible with Debian Linux

      Client NICs must be compatible with PXE boot.

      Avoid managed features on network equipment.
