Turn one M.2 slot into a serviceable, front-access dual-NVMe bay

The MiUM2776P+ is a professional storage expansion kit that enables faster serviceability without requiring chassis modifications. The kit is built around the iUM2776P+ (a dual-M.2 NVMe 3.5" drive module) and includes an M.2-to-MCIO adapter (MAP6-EZ) alongside a 50 cm MCIO cable.

At the core, the iUM2776P+ integrates a PCIe Gen3 switch with a PCIe Gen3 ×4 upstream link (up to ~3.94 GB/s theoretical payload per direction) and allocates Gen3 ×2 per SSD (up to ~1.97 GB/s theoretical per drive)—ideal for balanced, predictable dual-drive behavior in JBOD workflows.

For cooling under sustained workloads, the all-metal enclosure pairs passive heat dissipation with an integrated 2 cm low-noise fan to help reduce NVMe thermal throttling.

Key Features

1. Architecture & performance (balanced dual-drive I/O)

● PCIe Gen3 ×4 uplink, Gen3 ×2 per SSD via integrated PCIe switch (x2 + x2).

● JBOD by design: the host sees two independent NVMe drives (software RAID can be configured at OS/BIOS level if desired).

● MCIO (SFF-TA-1016) host interface for modern cabled PCIe/NVMe connectivity.

2. Serviceability & integration (built for uptime)

● Tool-free, lockable trays for fast SSD install/replace and reduced handling errors.

● Hot-swap capable hardware; actual hot-plug recognition depends on platform PCIe/NVMe hot-plug support.

● Standard SATA 15-pin power for broad chassis compatibility.

3. Thermal & mechanical (sustained performance in a standard bay)

● All-metal aluminum housing + active 2 cm fan for stable operation during 24/7 or heavy workloads.

● Standard 3.5" drive form factor (101.6(W) × 25.6(H) × 146(L) mm).

● LED indicators for power and drive status visibility.

4. MAP6-EZ adapter (M.2 → MCIO conversion)

● Converts a motherboard M.2 socket to MCIO (SFF-TA-1016) for cabled NVMe extension/relocation.

● Supports broad OS environments: Windows / Linux. macOS: supported on systems where the installed PCIe topology/HBA enumerates standard NVMe devices.

(Note: MAP6-EZ supports PCIe 4.0/5.0 hosts, but MiUM2776P+ operates at iUM2776P+’s PCIe Gen3×4 link.)

Applications

● Professional workstations (video/CAD/3D): swap “project” SSDs like media cartridges—fast turnaround without opening the chassis; use dual volumes for scratch + archive.

● Data centers / server racks: higher NVMe density in a standard bay; all-metal chassis + active cooling supports sustained duty cycles.

● AI / ML & analytics: rapid local dataset access and cache tiers using two independent NVMe devices.

● Edge computing / industrial systems: rugged enclosure, compact bay fit, and simple service access in constrained environments.

Why choose MiUM2776P+?

System integration notes

1. Power-on detection

Most motherboards do not natively support PCIe hot-swap, so the iUM2776P+ should be powered during system startup to ensure that it’s detected correctly.

2. Hot-swap vs. hot-plug recognition

The enclosure is mechanically hot-swappable, but for the OS to automatically recognize insert/remove events, your host platform (motherboard/HBA + topology) and OS must support PCIe/NVMe hot-plug. On systems without full support, a rescan or reboot may be required.

3. Gen4/Gen5 SSD compatibility

PCIe Gen4/Gen5 NVMe SSDs can be installed, but they will operate at PCIe Gen3 speeds due to the Gen3 switch architecture.

Frequently Asked Questions FAQ

Q1: What’s the difference between MiUM1776-P4 vs. MiUM2776P+?

A: MiUM1776-P4 is a single-NVMe 3.5" quick-swap kit (MAP6-EZ + enclosure) for simple, one-drive expansion (MAP6-EZ converts M.2 to MCIO; the enclosure side uses its own cabled interface).

MiUM2776P+ is the dual-NVMe option with an integrated PCIe Gen3 switch (Gen3 ×4 ~32 Gbps uplink, Gen3 ×2 per SSD) for higher density and balanced bandwidth.

Q2. Does it require a driver?

A: No—PCIe switch is OS-transparent when the platform supports NVMe.

Q3. Does it do hardware RAID?

A: It presents two independent NVMe drives; RAID can be implemented via software RAID (OS/BIOS/UEFI).

Q4. Will it work in a SATA/SAS backplane?  

A.  No—electrically it requires PCIe lanes via MCIO (not SATA/SAS-only bays).

Performance test result for reference. The test result will vary depend on the test environment.
