You need scalable, flexible solutions that are reliable, efficient and easy to manage.
Flash storage/NVMe (Non-Volatile Memory Express) is a scalable, high performance CPU PCI-E Gen3 direct connect to NVMe devices; designed for Client and Enterprise server systems using Solid State Drive (SSD) technology that was developed to reduce latency and provide faster CPU to data storage device performance.
By deploying NVMe, our customers can benefit from reduced latency, increased Input/Output Operations Per Second (IOPS), and lower power consumption. This means that customer solutions can perform more work in less time, translating into lower costs and increased revenues. Thus the ROI benefits for customers from NVMe enabled servers is immediate and substantial. Supports standard NVMe drivers.
- Large throughput gains (6x)
- Substantial latency improvements (7x)
- Shared common backplane improves flexibility of drive choice
- 2.5″ U.2 (SFF-8639) form factor for improved serviceability vs. PCI-E Flash cards (hot-swap)
- Improved power efficiency
The capacity of flash storage systems will continue to rise: the first flash modules of 4 terabytes (TB) in only 2.5 inches are appearing. Which is six times better than the most recent record. And the price / capacity ratio will continue to improve. Prices will fall further: in 2018, the price of one terabyte of flash memory will be the same than conventional hard disks. The “100% Flash” approach is already proving more economical. Studies show that, as of now, the overall cost of SSDs, including operation and maintenance, is less than that of conventional discs.

For the bandwidth test, Supermicro ran the IOMeter benchmarking tool on two SYS-1028U-TNR4T+ Ultra 1U servers, the first with standard SAS3 and SATA3 SSDs, and the second with NVMe SSDs. The upgraded configuration with NVMe delivered a maximum of 5.9x the performance of the server with standard SSDs.
For latency, the table shows the upgraded configuration with NVMe performed with up to 7.2x improved latency compared to the servers with standard SSDs.
While the base configuration delivered excellent performance, the dramatic performance improvement offered with the NVMe SSDs makes this upgrade an excellent investment for any business looking to improve the performance of its IT resources.
