Ubiquiti UACC-ESE-16 Enterprise Storage Expansion 16-Bay 3U Rackmount
Overview
The Ubiquiti UACC-ESE-16 is an Enterprise Storage Expansion unit designed to expand storage capacity for compatible Ubiquiti ENAS and ENVR-Core systems. It provides 16 shared 2.5-inch and 3.5-inch drive bays in a 3U rackmount chassis and connects to the host system through a 24G SFF-8644 expansion interface.
Storage Expansion
The enclosure supports up to 16 HDD or SSD drives in 2.5-inch or 3.5-inch formats. Ubiquiti specifies a maximum drive power budget of 500W. The expansion architecture is intended to provide additional storage capacity to compatible ENAS and ENVR-Core systems rather than operate as a standalone storage server.
Power and Connectivity
The UACC-ESE-16 provides one SFF-8644 24G expansion port and uses two AC inputs with hot-swappable power modules. Two 550W hot-swappable AC/DC power supply modules provide 1+1 power redundancy, while the maximum specified power consumption is 550W.
Rack Installation
The enclosure uses a 3U rackmount form factor. Its supplied rail system supports 600 mm four-post racks with square mounting holes and rack post depths from 600–1066 mm. The chassis uses SGCC steel for the enclosure and mounting structure.
Key Features
- 16 shared bays for 2.5-inch and 3.5-inch HDD or SSD drives
- 3U rackmount storage expansion chassis
- One SFF-8644 24G expansion port
- Two hot-swappable 550W AC/DC power modules with redundant power
- 500W maximum power budget for installed drives
Applications
The UACC-ESE-16 is intended for expanding the storage capacity of compatible Ubiquiti ENAS and ENVR-Core deployments. Its 16 drive bays and redundant hot-swappable power architecture suit rack-based storage expansion where additional HDD or SSD capacity is required.
DC Supplies Product Note
Compatibility should be confirmed at the host-system level before deployment. Ubiquiti identifies the UACC-ESE-16 as an expansion unit for ENAS and ENVR-Core, so it should not be treated as a general-purpose standalone SAS storage enclosure. Also verify rack depth and square-hole mounting compatibility before installation.
