With Auto Tiering, the TVS-EC1680U-SAS-RP R2 can automatically move hot data to high-performance storage tiers and cold data to lower-cost, higher-capacity drives, making the TVS-EC1680U-SAS-RP R2 an extremely efficient shared resource. Businesses will no longer have to invest heavily in expensive Flash technology, but can still enjoy exceptional application performance and lower TCO of storage from Auto Tiering with the TVS-EC1680U-SAS-RP R2. 12Gbps DataBolt™ Advantage Implementing DataBolt technology, the TVS-EC1680U-SAS-RP R2 can deliver twice the throughput for 6Gbps SAS drives by automatically aggregating the bandwidth from 3Gbps and 6Gbps drives to fully utilize 12Gbps, effectively accelerating the existing infrastructure. Excellent performance The TVS-EC1680U-SAS-RP R2 supports 12Gbps SAS drives to provide fast data transmission speeds and drive up to 3,820 MB/s throughput and 268,152 IOPS*. Powered by an Intel® Xeon® E3 v3 quad-core processor with 16GB or 8GB DDR3 ECC RAM, the TVS-EC1680U-SAS-RP R2 greatly enhances the efficiency of CPU-demanding tasks and serves more concurrent tasks. SSD cache acceleration The TVS-EC1680U-SAS-RP R2 features 2 pre-installed 128GB mSATA modules, and there are no limits on using SSDs for caching. By installing high-performance SSDs, the IOPS performance of storage volumes can remarkably boost. It is perfect for improving overall workflow of random IOPS demanding applications such as database and virtualization. The internal cache port design reserves the space of hard drive tray for more storage capacity. Removable motherboard drawer for easy maintenance With the TVS-EC1680U-SAS-RP R2's removable motherboard drawer, IT administrators have easier access in upgrading/installing RAM, the internal cache, 40GbE adapter and other components. The motherboard itself can be removed and replaced without needing to remove the heavy TVS-EC1680U-SAS-RP R2 from the rack cabinet, making it especially useful in maintaining the TVS-EC1680U-SAS-RP R2 in data centers with multiple rack cabinets.
