SK Hynix 7.68TB NVMe U.3 PCIe Gen 4.0 x4 RI SFF 2.5" 15mm SSD PE8110 Series for Cisco UCS C-Series Server

SK Hynix 7.68TB NVMe U.3 PCIe Gen 4.0 x4 RI SFF 2.5" 15mm SSD for Cisco UCS C-Series Server PE8110 Series

Compatibility Note

The SK Hynix PE8110 Series U.3 NVMe SSD is compatible with Cisco UCS C-Series rack servers that support NVMe U.2/U.3 storage. Full operation requires an NVMe-enabled backplane and a Cisco-compatible 2.5" SFF drive tray, since standard carriers from other vendors are not supported.

Core Specifications

• Capacity: 7.68TB
• Interface: PCIe Gen4 x4 (NVMe 1.4)
• Form Factor: 2.5" SFF (15mm)
• Connector: U.3 (backward compatible with U.2)
• Series: SK Hynix PE8110
• Controller: SK Hynix Aquarius (ACNT036M)
• NAND Type: 128-layer 3D TLC ("4D NAND")
• Workload Type: Read Intensive (RI)
• Endurance: 1.0 DWPD
• MTBF: ~2.5–3.35 million hours
• Power Consumption: ~10W active / ~5–6W idle
• Security: Digitally Signed Firmware (DS)

Performance

• Sequential Read: Up to 6,200 MB/s
• Sequential Write: Up to 3,870 MB/s
• Random Read (4K): ~190,000–582,000 IOPS
• Random Write (4K): Up to ~190,000 IOPS

Cisco UCS C-Series Server Compatibility

M7 / M8 Generations (PCIe Gen4 / Gen5 – Full Performance):
C220 M7, C240 M7, C225 M7, C245 M7, C240 M8SX, C240 M8L

M6 Generation (PCIe Gen4 – Native Support):
C220 M6, C240 M6, C225 M6, C245 M6

M5 Generation (PCIe Gen3 – Reduced Performance):
C220 M5, C240 M5, C480 M5

Important Deployment Notes

• Drive Tray Requirement:
  Must be installed in a Cisco 2.5" SFF drive tray compatible with the UCS chassis generation.
• Backplane Requirement:
  NVMe-enabled Cisco UCS backplane is required. SAS/SATA-only backplanes will not detect this drive.
• Interface Compatibility:
  U.3 is backward compatible with U.2, but full NVMe functionality depends on Cisco backplane and riser configuration.
• Performance Scaling:
  • M7/M8: Full PCIe Gen4 performance
  • M6: Full PCIe Gen4 performance
  • M5: Limited to PCIe Gen3 speeds (~3.5 GB/s max)
• Management Behavior:
  Cisco Intersight or CIMC may flag the drive as “non-Cisco” or “unsupported,” but it typically operates normally when NVMe is properly configured.

Summary

Enterprise 7.68TB NVMe U.3 SSD optimized for read-intensive workloads, fully compatible with Cisco UCS C-Series M5–M8 servers equipped with NVMe backplanes, with performance scaling based on generation.
