Synology RS3621xs+ External HDD Overview

This B&H Kit combines the Synology RackStation RS3621xs+ 12-Bay NAS Enclosure with twelve Synology 12TB HAT5300 SATA III 3.5" Internal Enterprise HDDs for a storage capacity of 144TB.

Synology RackStation RS3621xs+ 12-Bay NAS Enclosure

Engineered to deliver high throughput and robust data protection, the RackStation RS3621xs+ 12-Bay NAS Enclosure from Synology is a true enterprise powerhouse. Designed with a 12-bay, 2 RU storage form factor, built-in 500W redundant power supplies, an 8-core processor, ECC memory, advanced snapshot technology, and file self-healing, the RS3621xs+ provides a reliable founding to data-driven businesses. This unit has 12 drive bays, each of which natively supports 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs. Should users need to expand the overall capacity of their RS3621xs+, two optional RX1217/RX1217RP expansion units may be used to connect up to 24 additional drive bays, and each unit is connected using an integrated expansion port. The RS3621xs+ can deliver 4K random reads of up to 238,273 IOPS and sequential reads of up to 5819 MB/s.

The RackStation RS3621xs+ is powered by a 2.1 GHz Intel Xeon D-1541 Eight-Core processor, which will allow you to run multiple functions simultaneously. The built-in 8GB of DDR4 ECC RAM will allow quick access to frequently used files and programs and may also be upgraded to a total of 64GB by installing a 16GB module into each of the four DIMM slots. Also featured are two USB 3.2 Gen 1 Type-A ports, which allow it to be connected to external peripherals. Network connectivity is achieved via the two 10 Gigabit Ethernet or four Gigabit Ethernet ports with failover support, which help to provide redundancy in the case that a LAN connection malfunction occurs on one port. In addition, link aggregation helps to increase connection speeds beyond the limits of a single network port or cable. If you're looking to expand this NAS, there are two PCIe Gen 3.0 x8/x8 slots that support 10GbE network interface cards and M.2 NVMe adapter cards for an SSD cache.

The RackStation RS3621xs+ runs on the DiskStation Manager (DSM) operating system, which helps simplify managing your NAS, as well as accessing and sharing data. A variety of RAID modes are supported, which help provide users with data redundancy, speed, or a combination of both. Supported RAID modes include RAID 0, 1, 5, 6, 10, Basic, and Synology RAID F1. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized.

Synology has engineered the RackStation RS3621xs+ to be energy efficient. Not only does it offer four 80 x 80mm fans to help keep the system running cool, the server supports numerous scheduled power on / off cycles and hard-drive hibernation to further minimize power consumption and operation expenses. The RackStation RS3621xs+ operates on 100-240 VAC at 50/60 Hz and includes an accessory pack and two AC power cords. Protection is provided by a limited 5-year hardware warranty.
