Seagate Unified Storage Architecture: reducing storage System complexity

From 3.5 inches to 1.8 inches, from FC, SCSI to SAS, choosing storage Media is a headache for both businesses and OEMs.　　To this end, Seagate proposed the concept of a unified storage architecture. "The future of storage media will be more to the 2.5-inch, SAS interface, the overall encryption of the direction of development," said Bao, the Customer Technology Service Manager at Seagate Technology China. "Based on this, Seagate has made new plans for future enterprise-class product lines."　　In the future, Seagate will provide pulsar solid-state drives and Savvio 15K and 10K products for mission-critical tasks with high IOPS requirements.　　In addition, the Seagate Constellation series will take over Barracuda es hands of the banner, and in the Cheetah Ns.2 and cheetah with the assistance of the enterprise users to provide high reliability, cost-effective and low-power choice. Three elements of a unified storage architecture "at present, the market demand for 2.5-inch hard drives is growing rapidly." The frequent occurrence of data leakage events also makes self encryption a de facto security standard for static data protection products. "The SAS interface, the 2.5-inch specification, and the Bao storage media will become the mainstream of the future in the design of Seagate's unified storage architecture." Seagate will plan the product line according to this trend. From 2006 to 2009, the market share of 2.5-inch hard disk products grew from 9% to 48% in the first-tier storage market. Seagate expects the market share of 2.5-inch products to expand to 87% in 2011. "Bao said. 2.5-inch hard drive products are in hot pursuit of the market, because 2.5-inch hard disk products in the volume and power consumption are in line with the current data center energy-saving needs. "The 2.5-inch hard drive is 70% smaller than the 3.5-inch hard drive, with a weight of 72%," says Bao. In terms of IOPS per watt, a 2.5-inch hard drive is 2.5 times times the same type of 3.5-inch hard drive. OEMs can build a more high-density solution with a 2.5-inch hard drive, while reducing energy and cooling costs. The SAS interface is becoming the mainstream of the market. Bao said: "IDC expects that in 2011, 70% of the enterprise-class hard disk will use the SAS interface." In the past, people had to have different interfaces to the hard disk depending on the requirements, such as FC, 80-pin SCSI, 48-pin SCSI, and so on, resulting in a complex storage configuration. In the future, SAS will gradually become the main interface for multiple hard disk servers and storage arrays. "Self-encryption is also an important feature of the hard disk. Bao said: "All of Seagate's enterprise-class hard drive products can be based on customer demand for the encryption function." This is important to protect the customer's data security. "Two-tier storage requirements highlighted" in 2006, in the enterprise-class storage market, two-tier storage accounted for only 20%, compared to 38% in 2009, Bao said. Estimated to 2011Two-tier storage will account for about half of the enterprise's storage market.　　"Recently, Seagate expanded the original Barracuda ES series into constellation and constellation es two product lines to provide better support for level two storage." "Constellation series of products is characterized by the high reliability of enterprise-class hard disk, and has a good energy-saving characteristics." "Bao said," Constellation hard disk with new on-demand energy-saving technology Powerchoice, allows users to select the working state of the hard drive to achieve energy saving purposes. For example, constellation SAS hard Drive at Powerchoice Level 1 o'clock, power consumption from normal 2.82W to 2.42W, recovery time of 0.08 seconds, powerchoice level 3 o'clock, power consumption can be reduced to 1.82W, and can return to normal state in 1 seconds. SSD products have been available for a long time, but the real enterprise-class SSD needs the high reliability and durability that enterprise users need. There are few products in the market that can meet this demand. "Bao said.　　Although the launch of Seagate Pulsar is not long, this series of products undergo rigorous testing to ensure that the enterprise storage to meet the reliability and availability requirements. The High IOPS index is the advantage of SSDs. However, the performance of a long time after the decline and write performance is not a weakness of SSD. "Seagate has been committed to improving the write performance and stability of pulsar products so that it truly meets the requirements of enterprise-class applications," says Bao. "In addition to the Pulsar series products, Seagate Savvio 15K and 10K as well as the Cheetah product family are also products for tier-one storage applications." "Solid-state hard drives and traditional hard drives will coexist in the future," says Bao. Seagate offers a full range of products to meet the different needs of users. "However, from the plan of Seagate's Unified storage architecture, the 3.5-inch Cheetah series will gradually fade out of the market." The main advantage over Savvio 10k,savvio 15K is that the IOPS index is better, and the future SSD will be mainly used to meet users ' requirements for high iops metrics.　　Therefore, the Savvio 10K will be the most important traditional hard drive product line in the future. "2009, 2.5-inch 10K hard drive demand is 3 times times the demand for 2.5-inch 15K hard drives." In the future, this trend will continue. Seagate expects a 2.5-inch 10K hard drive to reach 69% in the first-tier storage market in 2011.　　"Bao said. Author: Huo
