UTran: UT34U2 NVMe U.2 Drives 4-Bay RAID Subsystem

UTran Technology, Inc. announced the UT34U2 NVMe RAID subsystem hardware-based RAID acceleration, that supports 4-bay U.2 drives.

The NVMe RAID subsystem UT34U2 adopts Broadcom, Inc. Tri-mode (SAS/SATA/NVMe) ROC SAS3516 with RAID functions and various OSs support.

There are 2 SFF8643 connectors in rear of RAID subsystem, utilizing PCle switch host card or passive card connecting host with SFF8643 cables (PCle Gen3 x8). It allows to hot-replace faulty drives without system shutdown. UT34U2 is subsystem providing high bandwidth and IO/s in data protection, and is for high-end server utilizing internal storage.

Key features:

• PCIe 3.1 host interface, PCIe Gen3 x8 lanes at maximum transfer rate up to 64Gb/s

• Device interface is PCIe Gen3 x4 per U.2 slot.

• Hardware-based RAID solution that supports RAID levels 0, 1, 5, 6, and 10.

• Off-load backup at power fail using ONFI (Supercap required), with bad block management.

• Implemented 4GB 72-bit DDR4-2133 SDRAM providing hardware RAID assist engine for parity calculations.

• Front LEDs for U.2 drives and RAID subsystem status indications.

• Buzzer beeping for any of RAID card failure conditions.
