SSD solid-state storage improves cloud data center performance

so how much do you know about this equipment? Now let's introduce the characteristics and working conditions of the manhole cover pressure testing machine. The computing performance of the data center market plays an increasingly important role in Moore's law, but the storage performance is facing great challenges. However, with the emergence of SSD solid-state storage, the data center storage market is ushering in new changes. Due to the huge scale of the data center, thousands or even tens of thousands of servers and the number of storage bring pressure on energy consumption costs, which gives SSD solid-state disk opportunities for survival and development

The initial application of SSD is limited to real-time and high performance application scenarios. However, with the development of emerging technology trends such as cloud computing and big data, SSD has begun to penetrate into the mainstream of storage. EMC, fusion IO, HDS, IBM, Intel, NetApp, Seagate, Samsung and other manufacturers have launched or are developing solid state disk products

the performance of storage hardware determines the operation of data center. In addition, hardware storage and arrays account for 98% of the cost of enterprise data centers, which requires that the performance of storage devices in enterprise data centers should be very strong and cost-effective. SSD has obvious advantages in improving the number of input and output IOPs per second, reducing power consumption and occupying a small space

from the data center storage applications, we can see that the applications of various forms of storage media have different levels, and the characteristics of applications in each application field are also different. Enterprises, especially Ansteel plate and Fengbao tube, have a good reputation in surrounding provinces and cities. They must adjust their arrays to take advantage of potential performance benefits. This process requires monitoring their information flow, storing the most frequently updated data in flash memory, and storing other data in hard disk. In addition, applications and operating systems also need to be adjusted so that enterprises can maximize the advantages of flash memory

in addition, the essential changes brought about by virtualization to the data center, and a large number of hard disks have increased the data volume and network data flow of the data center. Traditional SATA or FC disks will increase the response time when the data volume increases. The data center needs to use the characteristics of fast response and high IO processing capacity of solid state disks to meet the new requirements brought about by data growth

database acceleration is a common case of using full SSD arrays. For those OLTP applications with transmission processing, the continuous or sudden IO demand exceeds the maximum value that HDD Hard disk can provide, so full SSD array has special attraction. Another case where full SSD arrays can help is virtual desktop infrastructure VDI. Deploying a small number of SSDs can provide a stable speed for a large number of devices. Another part of the load is the virtualization of large-scale servers. The demand of a large number of servers located in the same storage for random access to data may exceed the limit of HDD cache. Full SSD storage allows people to get rid of the slow speed of accessing traditional disks. Perhaps the emerging industry most interested in this is big data analysis. SSD array can provide enough performance to conduct real-time data analysis for very large data

the deployment mode of full SSD storage is very similar to that of full HDD products. They have the same logical unit device number Lun, raid, and other features. Most suppliers support that all control parameters and measurement results on SSD can be displayed in real time on large screen LCD to realize the traditional raid function. Other common features in SSD array are its sharp weapon to compete in the larger array market. These features include thin configuration, de duplication and some other similar features. The management methods of different full SSD products are very different. HP 3Par uses 3Par management software suite for management. Other products provide different management methods for specific systems

another advantage that solid state drives can bring is low energy consumption. As the data demand of IT departments continues to grow, their power expenditure is also getting higher and higher. Therefore, they urge manufacturers to make their products more energy efficient. Because solid state drives store information in memory, they will not do as many read and write operations as hard disk storage. Because of these potential advantages, the solid-state disk market shows a rapid development momentum

ss moving beam is cast by high-strength mold. The consolidation of high rigid beam is not easy to damage, and accurate displacement measurement can be completed. One of the biggest problems of D technology is its predictable damage. A single storage unit can only write a limited number of times. Gradually, the performance of the disk will be reduced to the extent that it must be replaced. For consumer SSDs, multi-level cell MLC technology is usually used on PCs. the lifetime of this storage unit is only about 10000 write operations. The enterprise SSD, using single level cell SLC technology, can provide about 100000 writes

the future of enterprise disk arrays still lies in the mixed use of solid state drives and hard disk drives. Under the consideration of cost control, the advantages of the two are taken respectively. Hard disk drives can provide massive storage space, while solid state drives can provide high performance. SSD will not only not threaten the hard disk drive market, but also drive the storage demand of larger capacity under faster data processing

in the long run, it is expected that the large-scale application of solid-state disks will be seen in three years. Many data centers will adopt mixed methods, including adding solid-state storage arrays and purchasing servers that support SSD. The two will be combined, which can reduce network traffic, improve response time, and use hardware with smaller footprint, lower power consumption, and lower cost
