FAQs

Q: What distinguishes the 6238L from the standard 6238?
A: The ‘L’ suffix enables up to 4.5 TB of memory per CPU, especially with Intel Optane DC Persistent Memory, while core count and TDP remain similar.

Q: Is a heat sink included?
A: Typically no. Use the Cisco UCS-specific heat sink or thermal kit recommended for your server model.

Q: Which workloads benefit from the 6238L?
A: In-memory databases, SAP HANA, big data analytics, and large caches benefit from the expanded memory capacity.

Q: Can I pair a 6238L with a non-L CPU in the same server?
A: No. Use matched processors (same model/suffix and stepping) for multi-socket configurations.

Q: Does it require special memory?
A: Standard DDR4-2933 RDIMM/LRDIMM is supported; large memory capacities often use Intel Optane DC Persistent Memory modules in supported UCS platforms.
