BUFFALO TS51220RH1604 – TeraStation 51220RH 16TB 12-Bay 2U Enterprise NAS
Overview
The BUFFALO TS51220RH1604 is a TeraStation 51220RH enterprise NAS configured with four 4TB enterprise-grade HDDs in a 12-bay, 2U rackmount chassis. The configuration provides 16TB of installed raw storage while leaving eight drive bays available for expansion.
The platform is designed for business and data-center storage environments requiring centralized file storage, backup, virtualization-related storage, and network-attached storage with 10GbE connectivity. The factory RAID 6 configuration provides 8TB of effective capacity from the installed four-drive configuration.
Technical Information
The TS51220RH1604 uses an Annapurna Labs Alpine V2 AL524 quad-core processor running at 2.0GHz and 16GB of DDR4 ECC memory. The system provides two 10GBASE-T ports and two 1000BASE-T ports, supporting high-speed network connectivity and link aggregation.
Storage management supports RAID 6, RAID 5, RAID 10, RAID 1, RAID 0, and JBOD. The TS51220RH platform also supports hot-swappable drives and hot spares. Snapshot functionality, snapshot backup, iSCSI, iSCSI volume backup, replication, and failover support the platform's business continuity and data-protection capabilities.
SSD caching is supported on the TS51220RH platform using separately installed compatible SSDs. The system also provides firmware redundancy and an optional redundant power supply configuration.
Compatibility
The TS51220RH1604 uses 3.5-inch enterprise-grade nearline HDDs and supports SATA 6Gbps drive interfaces. Its network interfaces include two 10GBASE-T ports and two 1000BASE-T ports with support for IEEE 802.3ad Link Aggregation, flow control, 10GBASE-T, 1000BASE-T, 100BASE-TX, and 10BASE-T on the applicable interfaces.
The NAS supports iSCSI storage connectivity and can be used as additional storage for compatible server environments. The platform is also specified for VMware-related deployment and supports business NAS functions including replication and failover.
