TerraMaster U12-423 (Diskless)

TerraMaster U12-423 (Diskless), Intel® Celeron® N5105/N5095, 12-Bay, SATA, 2U NAS Server Storage System

 

TerraMaster U12-423
12-Bay High Performance NAS

 

 

Designed for High Performance Requirements

The 12-Bay U12-423 is suitable for SMB users who need high-performance storage solutions. High performance means that users can easily handle high-load assignments, while multiple business-level backup solutions guarantee user’ data safety and prevent the potential risk of data loss.

 

Excellent Performance

This is a high-performance storage solution for iSCSI virtual storage and database service for SMB users. It uses an Intel Celeron N5095 quad-core processor with 2.0 GHz and maximum turbo to 2.9 GHz. It is integrated with a GPU graphics card, AES NI hardware encryption, and equipped with two 2.5 GbE interfaces and 4 GB DDR4 dual-channel memory (expandable up to 32 GB).

 

The Ideal Choice for SMB’ Data Management

The U12-423 can deal with high-load workflow and a high level of concurrent user access. Rapid document storage and management are facilitated by high-speed document retrieval, efficient transmission performance, and rich TerraMaster disaster backup and recovery solutions.

Higher Transmission Speed

The U12-423 is configured with two 2.5 GbE interfaces, supporting 2.5 GbE high-speed network bandwidth. The transmission speed can reach 283 MB/s (Seagate IronWolf 18TB x 12, RAID 0) . Link Aggregation provides a network bandwidth up to 5 Gb, thus providing a cost-effective solution for multi-user and high-concurrent file access.

 

High Speed Network and Flexible Extension

The U12-423 is configured with two 2.5 GbE interfaces. Link Aggregation provides a network bandwidth up to 5 GbE. The built-in M.2 NVMe slot realizes SSD cache acceleration and significantly increases the storage efficiency of the disk array. To meet performance enhancement expansion requirements, the memory can be extended to as large as 32 GB.

Flexible Configuration and Management of Disk Arrays

The U12-423 supports rich RAID types, which can be selected based on your data access and data protection level requirements. Hot Spare can be configured for the disk array and any of the following array types can be chosen according to the number of hard disks: Single, RAID 0, 1, 5, 6, 10. To reduce the risk of material loss and ensure important materials are kept, the U12-423 supports online capacity expansion and online migration of RAID array.

 

Across-Platform File Management and Sharing

Supporting most of file services (SMB, AFP, SFTP/FTP, iSCSI, NFS, and WebDAV), the U12-423 can fully satisfy file management requirements in different network environments. TerraMaster’s web file management tool, File Manager, is easily operated with visualized interfaces, while its classification and search functions can make it simple to organize and share data.
