Overview

High-Performance Storage, Enterprise-Grade Reliability

The iUM2776P+ is a professional-grade 3.5-inch storage module designed to house two M.2 NVMe SSDs. Using an integrated PCIe Gen3 Switch and an MCIO (SFF-TA-1016) interface, this module supports PCIe Gen3 x4 (up to ~32 Gbps aggregate / ~3.94 GB/s theoretical payload, per direction) and allocates Gen3 x2 per SSD (up to ~16 Gbps / ~1.97 GB/s theoretical per SSD). Its rugged, all-metal construction and tool-free maintenance make it the ideal choice for high-density computing environments that demand speed, scalability, and zero downtime.

Key Features

● Tool-less Tray Design: Effortless, screwless SSD installation and removal.

● Hot-Swap Functionality: Hot-swap capable hardware; hot-swap behavior depends on host platform PCIe/NVMe hot-plug support.

● Dual M.2 NVMe Support: Compatible with 2230, 2242, 2260, and 2280 form factors.

● MCIO (SFF-TA-1016) Host Interface: Future-proof MCIO (SFF-TA-1016) connector for seamless modern platform integration.

● Host/Backplane Requirement (Electrical): PCIe Gen3 x4 via MCIO; not compatible with SATA/SAS-only bays for data.

● Universal Power: Uses a standard SATA 15-pin power input for easy deployment in any chassis.

● Advanced Thermal Management: All-metal aluminum housing paired with an integrated 2 cm low-noise cooling fan.

● Bay Compatibility (Mechanical): Fits standard 3.5-inch HDD Drive Bay

● Comparison: Standard Drive vs. iUM2776P+

Benefits

● Maximize Storage Density:

Pack the power of two high-speed NVMe SSDs into a single standard 3.5-inch bay. This allows you to double your drive count without upgrading to a larger chassis or server rack.

● Zero-Downtime Maintenance:

In platforms that support PCIe/NVMe hot-plug, drives can be serviced without shutting down; otherwise, a rescan/reboot may be required per system design.

● Future-Proof Connectivity:

By utilizing the MCIO (SFF-TA-1016) interface, you are aligning your hardware with the latest enterprise cabling standards, ensuring compatibility with next-generation motherboards and high-speed backplanes.

● Sustained Peak Performance:

NVMe SSDs are notorious for "thermal throttling" (slowing down when they get too hot). The combination of a precision-machined aluminum heat sink and an active 2 cm cooling fan ensures your drives stay cool even during 24/7 heavy workloads.

● Simplified Integration:

Despite its advanced internals, it uses a standard SATA 15-pin power connector. This "plug-and-play" approach means you can upgrade existing legacy systems to modern NVMe speeds without needing specialized power adapters.

● Enhanced Reliability:

The durable all-metal housing protects sensitive M.2 modules from physical damage and electromagnetic interference, making it suitable for harsh industrial or edge computing environments.

Ideal Applications

● Edge Computing & IoT:

Provides high-speed data caching and storage in compact, rugged environments where space is limited but performance is non-negotiable.

● Enterprise Data Centers:

Ideal for high-density server deployments requiring hot-swappable NVMe storage for rapid maintenance and upgrades.

● Professional Workstations:

Enhances video editing, 3D rendering, and CAD workflows by providing fast scratch disk space or redundant storage within a standard 3.5-inch bay.

● Industrial & Embedded Systems:

Rugged construction and effective thermal management make it suitable for industrial control, automation, and IoT platforms.

● AI & Machine Learning:

Supports the high-speed data throughput required for training models and processing large datasets.

System Integration Guidelines

1. System Power and Detection

• The iUM2776P+ connects directly to the motherboard via the PCIe interface. Since most motherboards do not natively support PCIe hot-swapping, the module must be powered on during system startup to be properly detected.

• If the iUM2776P+ is not powered on during system startup, the operating system may fail to recognize the module.

2. Hot-Swap Functionality

• The system can boot normally even if no SSD is installed in the iUM2776P+.

• M.2 NVMe can be inserted/removed while running. Recognition behavior depends on platform hot-plug support; a rescan or reboot may be required per system design.

Frequently Asked Questions (FAQ)

Q1: Does the iUM2776P+ support PCIe Gen4 or Gen5 SSDs?

A: The iUM2776P+ is designed with a PCIe Gen3 x4 switch. PCIe Gen4 or Gen5 NVMe SSDs can be installed, but will operate at PCIe Gen3 speeds to ensure compatibility and stability.

Q2: Does the iUM2776P+ support RAID?

A: Yes. The module features a PCIe switch that allows the host to see two individual NVMe SSDs. RAID functionality (such as RAID 0 or RAID 1) can be implemented via the operating system (Software RAID) or a compatible BIOS/UEFI setting on your motherboard.

Q3: What M.2 SSD sizes does the iUM2776P+ support?

A: The iUM2776P+ supports M.2 NVMe SSDs in 2230, 2242, 2260, and 2280 form factors.

Q4: Does it require a special driver?

A: No. As a hardware-level PCIe switch, it is transparent to the operating system. If your system supports NVMe and has an MCIO (SFF-TA-1016) port, the iUM2776P+ will work out of the box.

Q5: Will this fit in a standard 3.5-inch HDD bay?

A: Yes—mechanically it matches a 3.5-inch drive footprint. Electrically, it requires PCIe lanes via MCIO (SFF-TA-1016) and will not work if the bay/backplane only provides SATA/SAS connectivity.

Q6: What type of host connection is required for the iUM2776P+?

A: The iUM2776P+ uses an MCIO (SFF-TA-1016) connector and requires a compatible PCIe host interface or adapter cable that supports PCIe Gen3 x4 signaling.

Q7: What power connection does the iUM2776P+ require?

A: The iUM2776P+ uses a standard SATA 15-pin power connector, making integration into existing systems easy.

Q8: Can the 2cm cooling fan be disabled?

A: The built in 2cm cooling fan is designed to operate automatically to ensure thermal stability. Disabling the fan is not recommended, as it may impact SSD reliability and performance.

Q9: What are the typical use cases for the iUM2776P+?

A: The iUM2776P+ is designed to work with HOST BUS controller and is ideal for workstations, edge computing systems, data centers, industrial platforms, and media production environments that require compact, high-speed, and easily serviceable storage.

Q10: Will it work in a SATA/SAS backplane?

A: No; it needs PCIe lanes via MCIO (SFF-TA-1016) or adapter.
