Cisco has announced that their UCS servers are now updated with 2nd generation Intel Xeon Scalable processors. Servers now include higher top-end frequencies, Intel's Optane DC persistent memory with 128GB, 256GB, and 512GB module capacities, support for 256GB DIMMs DDR4 2933-MHz memory, hardware mitigations for multiple side-channel attacks and Intel Speed Select Technology.
Cisco states the following modes for UCS servers:
- Memory mode, where lower-cost, higher-capacity Intel Optane DC persistent memory modules are paired with DDR4 DIMMs to lower costs. For example, users now have two options to increase per-socket memory to 3 TB: 12x 256GB DDR4 DIMMs, or the most cost-effective option of 6x DDR4 DIMMs + 6x 512GB Intel Optane DC persistent memory modules.
- Direct Mode App, where the Intel Optane DC memory modules are used as low-latency, high-speed persistent memory for data or storage attached directly to the CPU instead of the PCIe bus. Each CPU can have up to 1.5 TB of DDR4 memory and up to 3 TB of App Direct memory / storage. This allows application developers to customize their code to make the best use of each memory type.
With UCS Manager, users can dynamically define how Intel's Optane DC persistent memory is used (i.e., memory mode, direct mode, or both) as well as how much is configured for each.
Cisco adds that their Intersight technology makes them more flexible, such as B-Series blades, C-Series rack and multinode servers, S-Series dense storage servers, and HyperFlex hyperconverged servers. Intersight, a software-as-a-service-management platform that provides proactive automation and support, can help reduce costs and faster time-to-resolution.
