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.

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.
