## Announcement Announcement **New SAP certification: 6, 8, and 12 TB X4 machine types for SAP HANA scale-up workloads** For use with SAP HANA scale-up (OLTP and OLAP) workloads running on Google Cloud, SAP has certified the following Compute Engine X4 machine types: * `x4-480-6t-metal` \- 6 TB memory * `x4-480-8t-metal` \- 8 TB memory * `x4-960-12t-metal` \- 12 TB memory With this certification, the names of all X4 machine types have been updated to convey the memory they offer. For example, `x4-megamem-960-metal` is renamed to`x4-960-16t-metal` because it offers 16 TB memory. This change is backwards compatible.
