4U space for sixty hard drives
The TL-R6020Sep-RP provides sixty 3.5-inch SAS/SATA HDD slots, delivering petabyte-level massive storage in a single chassis. QNAP NAS allows flexible management of connected TL-R6020Sep-RP storage space through the Storage & Snapshot Manager app.
The available space for a single machine is up to
1 PB
Adding a single chassis can expand the effective capacity to PB level
The TL-R6020Sep-RP provides a single chassis effective capacity of 1 PB, which can meet the capacity requirements of long-term high-definition digital surveillance.
1. Estimated bit rate is 2Mbps and 4Mbps for 1080P H.264 and 4K H.265 respectively.
2. The available storage capacity calculated using sixty 24TB HDDs in RAID 60 with 10% over-provisioning.
Flexible cascading of up to 4 JBODs for expansion up to 4PB of the available storage capacity
The TL-R6020Sep-RP features four 12Gb/s SAS 3.0 SFF-8644 SAS wide ports, allowing connection to a NAS host with a SAS expansion card. Up to four TL-R6020Sep-RP units can be daisy-chained together, expanding your NAS by 240 hard drives for up to 4PB storage space. Multipath redundancy technology supported by the NAS host ensures smooth data transfer and access, maintaining uninterrupted system service.
We recommend using the QXP-1630S-3816 PCIe 4.0 quad-port external SAS 12Gb/s storage expansion card.
Diverse JBOD connection methods improve overall performance
The TL-R6020Sep-RP is not limited to daisy chaining. By installing more SAS storage expansion cards in the NAS, you can reduce the number of single-cluster TL-R6020Sep-RP drives and improve overall performance. TL-R6020Sep-RP can also expand an existing QNAP TL SAS JBOD by adding two more, increasing the existing storage capacity to petabyte-level.
Streamline rack space, reduce weight and power consumption
With 4U of space and sixty hard drives, the TL-R6020Sep-RP significantly reduces rack space usage, power consumption, and weight. Pre-configured with the RAIL-H01 rail kit and an optional cable management kit, the freed-up space can easily organize complex cabling, thereby reducing long-term maintenance costs.
1. For information on rail and rack depth, please refer to the rack kit page.
2. The reference weight shown in this diagram does not include rail.
Monitor each hard drive from the front panel
The TL-R6020Sep-RP features sixty hard drive status indicators (blue and red) on the front panel, eliminating the need to pull the system from the rack and open the top cover to access the drive trays. A pull-out label also serves as a rack label, making it easy to identify and manage individual TL-R6020Sep-RP.
Mechanical design that facilitates maintenance and management
The TL-R6020Sep-RP features easy-to-replace drive trays and system cooling fans. Six 120mm x 120mm fans ensure adequate airflow for system cooling. A chassis depth of only 750mm facilitates deployment in racks up to 1M in depth, reducing installation difficulty.
QuTS hero's ZFS file system is a natural fit for petabyte-scale storage
Built using the ZFS file system, QuTS hero provides a highly reliable storage solution. By connecting TL-R6020Sep-RP JBODs, capacity can be expanded to petabytes, meeting requirements for explosive growth of data storage while safeguarding critical business data.
ZFS offers self-healing capabilities to prevent silent data corruption, performing checksum verification on all data blocks and automatically repairing erroneous blocks. If static data corruption occurs due to hardware failure (such as a broken cable), driver errors, or metadata errors, the next time the block is read, a checksum discrepancy is detected and data is automatically repaired. This maintenance ensures data integrity and accuracy and is essential for petabyte-level data.
