  • Data Storage Security in Cloud Data Center

    With the development of cloud computing, cloud data centers are used more and more widely. More and more enterprises choose to use cloud data storage services. In this way, they need not buy expensive equipment or hire specialized personnel to manage data responsibilities. At present, the data storage security in cloud data center has become the first condition for enterprises to choose their own cloud platform (cloud data center). So, how to define data storage security? We can consider these aspects: data stability, high availability, data access security and data durable availability. Data Stability The data storage service provided by cloud data center should ensure the stability of each tenant’s access. It will not affect the normal business access of other tenants because of the sudden large number of I/O access to storage by individual tenants. In the design of SAN network architecture, the overload ratio between host and storage is considered to avoid congestion or performance degradation. At the same time, the core-edge SAN network design architecture is adopted to achieve flexible expansion. The response time and processing capacity…

  • The Global Optical Transceiver Market Is Striding to 200G/400G

    The demand for higher speed, couple with the prevalence of cloud computing, Internet of Things (IoT) and virtual data center, has driven the prosperity of optical transceiver market. Optical transceiver, Direct Attach Cable (DAC) and Active Optical Cable (AOC) have evolved dramatically to catch leading edge broadband network capacity. The past decades have witnessed massive adoption of optical transceivers with data rates ranging from 1G, 10G and 25G, to 40G and 100G, while higher-speed — 200G/400G is just on the horizon. The sales of optical components grows steadily and is expected to continue in the years to come. Mature Data Center — 10G, 25G, 40G and 100G As network gets faster and virtualization gradually becomes the norm, data center is undergoing a major transformation. The trend emerges in the industry signifies a migration toward higher speed transceivers and better service. These transceivers are driving revenue growth which suggests a strong market. The global optical transceiver market is anticipated to reach to $9.9 billion by 2020, driven by the widespread use of 10G, 25G, 40G and 100G optics, and with the biggest sales forecasted for…
