24 Bays Behind a Dual EPYC? TFNEW S557E4
TL;DR: TFNEW launched the S557E4, an enterprise storage server, on September 21, 2026. A 4U high-density storage design with up to 2x AMD EPYC 7003/7002 (225 W), 16 DDR4 ECC slots (up to 4 TB) and 24 front hot-swap drive bays with RAID 0/1/5/6/10/50/60 support — array-scale capacity with dual-socket EPYC compute.

Core Specifications (with Plain-Language Terms)
The S557E4 (model S557E4-TR162) pairs TF NEW's 24-bay front storage bank with dual-socket AMD compute: up to 2x AMD EPYC 7003/7002 series processors at 225 W TDP, with 16 DDR4 ECC RECC DIMM slots (8 channels per CPU) up to 3200 MHz and 4 TB. Storage: 24x front 3.5"/2.5" compatible hot-swap SATA/SAS bays plus 2x internal 2.5" SATA/SAS SSDs. RAID support is the full enterprise menu — RAID 0/1/5/6/10/50/60 via optional standalone RAID card; SAS drives require the standalone RAID card. This is the storage server for arrays that want both: EPYC's per-socket bandwidth and 24 bays of capacity in one 4U, with dual-socket compute headroom for data services running beside the array.

Why Dual EPYC Behind 24 Bays Is a Compute-Capable Array
Storage arrays usually get single-socket compute; the S557E4 gives the 24-bay bank two EPYC 7003/7002 processors instead. Dual-socket AMD compute changes what the node can do beyond holding disks: deduplication, encryption, compression, analytics and storage virtualization all run with real CPU headroom, while 16 DDR4 ECC slots keep metadata and working sets resident. Full RAID 0/1/5/6/10/50/60 support covers the array-architecture spectrum from parity efficiency to mirroring safety. It's the 4U storage node for teams that want array density and server compute in one box.
Where It Fits
- Compute-capable storage arrays: 24 bays with dual-socket EPYC headroom
- Encrypted and compressed storage: inline data services without a slow node
- Virtualized storage nodes: dual EPYC for storage VMs and services
- Scale-out capacity with smarts: RAID 0/1/5/6/10/50/60 flexibility
Why the Numbers Matter
- 24 front hot-swap bays: array-scale capacity in a 4U
- Dual EPYC 7003/7002 at 225 W: server-grade compute behind the disks
- 16 DDR4 ECC up to 4 TB: resident metadata and working sets
- RAID 0/1/5/6/10/50/60: the full enterprise RAID spectrum
- 2x internal SSDs: fast tier inside the node
What TF NEW Says
"Storage nodes with single-socket compute are fine until the data services show up," said a TF NEW product manager. "The S557E4 puts dual EPYC 7003/7002 behind 24 front bays — dedup, encryption and analytics run on real CPU headroom, with 4 TB of ECC DDR4 and full RAID 0/1/5/6/10/50/60 support. Array density and server compute in one 4U."
Quality and Availability
Every S557E4 is burn-in tested under sustained I/O across all 24 bay paths — drive channels, memory and RAID controller validated for 48 hours before shipping. It ships deployment-ready with RAID and array configuration documentation.
