QNAP TL-R1620Sdc 16-Bay Dual-Controller SAS Expansion
Redundant SAS Expansion for a Qualified QES System The QNAP TL-R1620Sdc adds sixteen drive positions to a compatible dual-controller QES storage system. It is an expansion enclosure rather than a standalone NAS: the connected host controls storage, shares and applications. Its paired controllers support an appropriate redundant path design for enterprise storage. Choose the host, drives and topology as one system before commissioning a larger array. Highlights Enterprise SAS Connection Two controller modules, each with 3 × Mini-SAS HD SFF-8644 SAS 12Gb/s wide ports. Each wide port has four SAS lanes; dual-controller resilience requires a qualified dual-path topology. For supported dual-controller QES NAS, including ES1686dc R2, ES1686Adc and ES2486AFdc in qualified configurations. QES 2.1.1 or later and the correct SAS ports or supported SAS adapter are required; confirm the exact NAS and firmware. Sixteen Qualified Drive Positions Qualified 3.5-inch or 2.5-inch SAS HDDs and 2.5-inch SAS SSDs at 12/6Gb/s. Qualified 2.5-inch SATA SSD use requires a suitable QDA-SA2 adapter and confirmed host/drive compatibility; SATA HDDs are not a direct dual-controller substitute. Disks are supplied separately; plan RAID groups and recovery on the host. Serviceable Rack Design 3U short-depth chassis with hot-swappable drive bays. Dual 550W power supplies and three cooling fans. Controlled Expansion Up to 7 enclosures on an appropriately supported QES system; actual limits depend on the qualified host and topology. Five-year manufacturer warranty; rails are optional.

QES 2.1.1 or later and the correct SAS ports or supported SAS adapter are required; confirm the exact NAS and firmware. The enclosure has no independent Ethernet file-sharing service and does not run a separate NAS application platform. A USB, Ethernet or similarly shaped cable does not replace the required SAS connection. Plan Resilient Paths Deliberately Two controller modules, each with 3 × Mini-SAS HD SFF-8644 SAS 12Gb/s wide ports. Each wide port has four SAS lanes; dual-controller resilience requires a qualified dual-path topology. Route cables and power for the intended failure scenario. A redundant component is only one part of availability; host configuration, drive health and a separate backup still matter. Select the Correct Drive Interface Qualified 3.5-inch or 2.5-inch SAS HDDs and 2.5-inch SAS SSDs at 12/6Gb/s. Qualified 2.5-inch SATA SSD use requires a suitable QDA-SA2 adapter and confirmed host/drive compatibility; SATA HDDs are not a direct dual-controller substitute. Do not mix HDDs and SSDs in one RAID group. Check the exact drive model, firmware, sector format and intended RAID layout before ordering or moving an existing array. Scale Storage Without Assuming Every Host Fits Up to 7 enclosures on an appropriately supported QES system; actual limits depend on the qualified host and topology. Chassis count alone does not establish the usable storage capacity or performance. Account for the selected drives, RAID overhead, supported pool limits and the resources of the connected host. Manage Storage Through the NAS The supported host controls storage groups, pools and applicable snapshots. Enclosure monitoring covers relevant drive and hardware status through the supported management software. This expansion does not add processor or memory resources to the NAS, camera recording licences or application entitlements. Install with Room for Service The 3U chassis measures 425.3mm deep before protruding fittings. Choose the optional RAIL-B02 for a compatible rack, or another exact current rail verified for the rack depth and this enclosure. Allow rear cable clearance, supported power distribution and ventilation. The power ratings are maximum supply capacities rather than a promise of constant consumption. Keep Recovery Separate from Capacity An expansion increases available storage positions; it is not an independent backup merely because it uses a second chassis. Keep another appropriate copy of important data and a tested recovery plan. Any optional service coverage must be confirmed for the registered NAS and attached configuration. Summary The TL-R1620Sdc is a way to add enterprise drive capacity when the host, interface and installation have been checked together.
