24 Bays With Optane DC Support? TFNEW S547G3
TL;DR: TFNEW launched the S547G3, an enterprise storage server, on September 21, 2026. A 4U high-density storage design with up to 2x Intel Xeon Scalable (Skylake/Cascade Lake, 205 W), 16 DDR4 RECC slots (up to 2 TB) and 24 front hot-swap drive bays — with Intel Optane DC persistent-memory support on 2nd Gen Scalable processors.

Core Specifications (with Plain-Language Terms)
The S547G3 (model S547G3-JR164) is the Intel-front-bank member of TF NEW's 24-bay storage family: 24 front 3.5"/2.5" compatible hot-swap SATA/SAS bays behind up to 2x Intel Xeon Scalable processors (Skylake and Cascade Lake series) at 205 W TDP on an Intel C621 chipset. Memory: 16 slots, 6 channels per CPU, DDR4 RECC up to 2933 MHz and 2 TB — plus up to 2 TB of Intel Optane DC persistent memory when paired with 2nd Gen Scalable processors. Optane DC (Intel's persistent-memory class) keeps data across power cycles at memory-like speed, which changes storage-node design: caches, metadata and tiering data can live in non-volatile memory instead of disk. Optional standalone RAID card drives the array; SAS drives require it.

Why Persistent Memory Changes What a Storage Node Cannot Cache
Metadata, index and tiering structures are the hot data of any large array — and on most nodes they live on disks or in DRAM that forgets everything at power-off. The S547G3's Optane DC support puts up to 2 TB of that hot data in persistent memory: memory-speed access that survives reboots, so caches and metadata don't have to be rebuilt from disk after every restart. Twenty-four front bays give the bulk capacity; persistent memory gives the node a non-volatile fast tier that plain DDR4 arrays simply don't have. It is the Intel-era way to make a dense storage node both fast and survivable.
Where It Fits
- Metadata-heavy arrays: Optane DC for structures that must survive reboot
- High-density capacity nodes: 24 front bays in a 4U
- Caching and tiering servers: persistent memory as a fast, non-volatile tier
- Intel-ecosystem storage: Skylake/Cascade Lake with mature C621 drivers
Why the Numbers Matter
- Up to 2 TB Optane DC: persistent, memory-speed hot data
- 24 front hot-swap bays: array-scale capacity in a 4U
- 2x Xeon Scalable at 205 W: dual-socket compute behind the array
- 16 DDR4 RECC up to 2 TB: DRAM plus persistence in one memory map
- SAS-ready RAID option: array architecture to taste
What TF NEW Says
"On large arrays, the metadata is the bottleneck and DRAM forgets it at every reboot," said a TF NEW product manager. "The S547G3 puts 24 front bays next to 2 TB of Optane DC persistent memory — index, cache and tiering data at memory speed that survives power cycles, on dual Scalable processors. Dense capacity with a non-volatile fast tier."
Quality and Availability
Every S547G3 is burn-in tested under sustained I/O across all 24 bay paths — drive channels, memory channels and RAID controller validated for 48 hours before shipping. It ships deployment-ready with RAID and Optane configuration documentation.
