12-bay rackmount NAS with 48TB

The Buffalo Technology TS51220RH4812 is a 12-bay rackmount network-attached storage system pre-populated with twelve 4TB drives for 48TB total capacity. It runs on an Annapurna Labs AL524 quad-core processor at 2.04GHz with 16GB DDR4 memory. Designed for businesses needing high read/write performance through hardware RAID in a 2U form factor.

Dual 10GbE and 1GbE network ports

Connectivity is handled by two 10GbE and two 1GbE RJ-45 ports supporting IEEE 802.3, 802.3u and 802.3ab standards. This mix allows fast backbone links and standard client access simultaneously. The single specification that decides fit is whether your infrastructure can use 10GbE uplinks; without 10GbE switching the extra throughput cannot be realised.

Tool-less drive bays and included railkit

Installation uses tool-less drive trays that slide into the front bays and a railkit for rack mounting. The unit weighs 55.37 lbs so two people or a lift are recommended for rack placement. Common issues include forgetting to initialise the RAID array before storing data and not configuring the 10GbE ports for jumbo frames to reach advertised throughput.

Klausimai apie šią prekę

How does the AL524 2.04 GHz quad-core processor with 16GB DDR4 handle heavy RAID workloads?

The quad-core AL524 at 2.04 GHz paired with 16GB DDR4 delivers high read/write throughput across RAID 0, 1, 5, 6, 10 and JBOD arrays.

What do the two 10GbE ports actually cap at in a typical network?

Each 10GbE port supports up to 10 Gbps per IEEE 802.3ab; real-world throughput depends on switch, cabling and client capabilities.

What rack depth and clearance does the 12-bay chassis need?

The unit measures 29.0 x 18.9 x 3.4 in and includes a railkit for standard rack mounting.
