Questions fréquemment posées
The QNAP QXP-820S-B3408 SAS card is primarily designed to expand the storage capacity of a QNAP NAS by enabling connections to TL SAS JBOD storage enclosures and REXP expansion units. It allows for daisy-chaining multiple expansion units via mini SAS HD cables, supporting total disk capacity expansion up to 4.6PB. This makes it ideal for businesses requiring large-scale storage solutions for virtualization, surveillance, Big Data, video editing, and TV broadcast storage.
The QXP-820S-B3408 features a PCI Express 3.0 x8 host interface and supports 12Gb/s SAS connectivity. It comes with two external SAS ports using SFF-8644 connectors, with each SAS port combining four 12Gb/s SAS channels to deliver up to 48Gb/s per host connection. The card uses a Broadcom SAS3408 Tri-mode controller and is designed in a low-profile, plug-in card form factor.
SAS offers significantly better performance compared to SATA on this card. While SATA operates at 6Gb/s with 10-20% workload capacity and higher latency, SAS operates at 12Gb/s with 100% workload capacity and lower latency. Additionally, SAS offers better reliability with 1.2-1.6M hours MTBF at 45° compared to SATA's 700,000+ hours at 25°. This makes SAS ideal for enterprise-level storage solutions requiring high performance and reliability.
The QXP-820S-B3408 can support up to 4.6PB (Petabytes) of total storage capacity. This is achieved by daisy-chaining up to 16 devices, including TL SAS JBOD storage enclosures and REXP expansion units. This calculation is based on using 18TB drives in sixteen 16-bay enclosures, making it suitable for large-scale enterprise storage requirements.
The package includes the QXP-820S-B3408 High-Bandwidth, Full Duplex 12Gb/s SAS Card along with multiple mounting options including desktop brackets, full-height brackets, and low-profile brackets. This ensures compatibility with various server and workstation configurations.
The QXP-820S-B3408 offers several features for business continuity and reliability. It supports flexible port configuration for multipath or link aggregation, which helps balance data transfer loads effectively. This configuration prevents backup failures and ensures uninterrupted system services. The card also provides low-latency, power-efficient, and IOPS-optimized storage capabilities through its SAS interface.
Yes, the QXP-820S-B3408 is environmentally friendly and holds China RoHS certification, demonstrating compliance with environmental standards for electronic components. This certification ensures the product meets specific requirements for restricting the use of hazardous substances in electronic and electrical equipment.
The QXP-820S-B3408 is ideally suited for businesses requiring high-reliability IT environments, specifically in sectors such as virtualization, surveillance, Big Data analytics, video editing, and TV broadcast storage.
