Thank you for contacting Intel Server Support.
I will attach a file that I extracted from https://serverconfigurator.intel.com/, where indicates the Seagate HDDs compatible with your system.
However, the interactive technical support for the Intel® Server Board S2600GZ you have requested has been discontinued. We can provide you with resources and self-service support information through our website. We highly suggest that you get information from the product support site https://www.intel.com/content/www/us/en/support/products/56253/server-products/legacy-server-products/intel-server-board-s2600gz-family/intel-server-board-s2600gz.html and all available technical information is included on the support site.
Have a wonderful day.
Intel Server Specialist.
