In recent years, as the market price of NAND Flash continues to fall, the price of SSD has decreased accordingly, and the reduction in flash memory costs has broadened the scope of use of high-performance SSDs. Among them, the NS series NVMe SSD independently developed by Inspur Storage helps users in various industries to cope with complex businesses in the new data era, with its three advantages of extreme energy efficiency, extreme stability and extreme reliability. It is an extremely cost-effective choice among enterprise-level NVMe SSDs.
technical strength
Inspur Storage independently developed NS6510G1 and NS6610G1 enterprise-level mainstream SSDs have been widely favored by customers since they were launched for their high performance and low price. They have now helped distributed storage SPC-1 and Inspur InCloud Rail SPECVirt reaches the world's number one . Sequential read and write 3300/1700MB/s, random read and write 570/160k, delay of 83/14, average fault-free working time of 2.6 million hours, reaching the industry-leading level. With its excellent cost control and design optimization, Inspur NVMe SSD even has a price comparable to SATA SSD , and its performance is several times better than SATA disks. To date, it has become a data storage for enterprises of various sizes. The best vector for getting the matrix.

A simple SATA SSD is gradually difficult to meet. More and more customers are turning their attention to NVMe SSDs with stronger performance and more stable performance.
Compared with SATA SSD, the high performance of NVMe SSD is mainly reflected in the two fields of I/O performance and delay. On the one hand, when data is transferred from storage to the server host, it enters a row or queue. A SATA SSD connection can only support one queue and can only accept 32 pieces of data at a time. NVMe SSD can support up to 64,000 queues, with each queue having 64,000 entries. On the other hand, the standard time of NVMe SSD is for PCIe SSD. Direct connection with CPU using native PCIe channel can eliminate the delay caused by the communication between the external controller (PCH) of SATA and SAS interface and the CPU. At the software level, the NVMe SSD standard delay is less than half of AHCI , and you do not need to read the register when calling the command; while each AHCI command needs to read 4 registers, consume 8000 CPU cycles, resulting in about 2.5μs Delay. Enterprise-level NVMe SSD is known for its performance. In the scenario of quickly processing data, 2.5μs affects customer experience, and its impact on the business far exceeds literal data of 2.5μs. Although the price gap in hard disk itself has caused expensive solution costs, Inspur's self-developed NVMe has achieved extreme cost optimization by exploring NAND characteristics.
At the same time, when building data redundant arrays, with the help of intel VROC (Virtual Raid on CPU) technology dedicated to serving enterprise-level NVMe, it can directly build Raid on PCIe channels without the need for additional storage controllers, which greatly saves Raid cost and combined with single disk cost optimization, ultimately making Inspur's self-developed NVMe data disk solution extremely competitive.
In the server field, SATA SSDs are more widely used and have a larger volume, but they are slower to read and write in terms of performance, and the SATA protocol has been finalized and can no longer be updated later. Based on this, Inspur proposed two SATA alternative solutions: Trimode solution and VROC solution. The Trimode solution is based on RAID card and can support Windows, Linux and other systems, but it can use up to 4 cards at a time, and use up to 8 cards after changing the backplane. There is a bottleneck in uplink bandwidth, PCIe3.0 × 4 or × 8. On this basis, the price is higher under the same circumstances, and multiple NVMe cannot perform the full performance of SSD when running at the same time. The corresponding cost of VROC solutions is lower, which is close to SATA. On the other hand, NVMe SSD has no upper bandwidth bottleneck, and the PCIe protocol can be continuously updated, so the performance of SSD can be fully utilized.
data comparison
RAID 0, a way to access data that distributes continuous data to multiple disks, representing the highest storage performance among all RAID levels.
Classic RAID 0 scene consists of 8 960G SATA SSD and 8i 2G memory. After replacing the 8 S4510 SATA SSD in the RAID 0 classic configuration with 4 Inspur's self-developed 1.92T NS6510G1 NVMe SSD, you can get the corresponding VROC solution. With the support of 16i's 4G memory, you can also get 4 RAID cards Trimode solution. In addition to the performance comparison of single disks, it can also be clarified that NVMe SSD performs better in specific scenarios, especially VROC solutions, which can improve performance by 2.2-11.2 times when the cost increases by less than 20%. Similar to
, Inspur NVMe SSD also performs excellently in the RAID 5 scenario that takes into account performance, security and cost. Trimode's price rises by about 30% when it improves performance by 1.8-4.9 times, while VROC's price rises by less than 20% when it improves performance by 1.3-8.9 times. It is worth mentioning that in various scenarios, the price of VROC solutions has always been lower when their performance is comparable to or even better than that of Trimode solutions, and it does not have to be restricted by the RAID card supply.
According to NSG Forecasting's forecast, SATA/SAS market share is continuing to be squeezed by PCIe. By the end of this year, PCIe's market share will account for more than 85%. With PCIe's strong market competitiveness, SATA/SAS SSDs will definitely gradually switch to NVMe SSDs in the future. From this perspective, if you can take the lead in deploying NVMe SSDs, you can maintain the advanced business in the competition and make your business ahead of your competitors.
