Union Memory’s SSD at the Level of Data Center Helps Operator to Develop Ultra-high Performance Flexible Volume Service


Partner Requirements

With the explosive growth of data, the storage mode has gradually changed from centralized storage to distributed storage. Distributed storage has the advantages of high flexibility, high reliability, and high efficiency through the scalable system structure that allows multiple servers to share the storage risks.There is an operator who uses distributed storage as the storage base in practical applications to provide users with ultra-high performance flexible volume services, and support services with requirements to high performance, such as desktop office, enterprise ERP, and portal. It has become the focus of the operator of how to ensure the high reliability and linear expansion of the storage system while meeting the requirements for fast desktop distribution, avoiding startup storms and guaranteeing the normal operation of various high-performance business scenarios.

Solutions

Based on the operator's actual requirements, Union Memory proposed the DSSD storage solutions to meet the operator's requirements for high performance.

Description of the Solution:  

•The storage server is a 2-way rack server equipped with a 2-way Intel Xeon 6230 high-performance CPU, 256GB memory, and 2 * 25GE links bound to the East-West/North-South link
•The storage pool adopts the three-copy redundancy mechanism to ensure the highest reliability while optimizing IO-intensive and bandwidth-based services
•About 400,000/100,000 IOPS reading/writing for single node, 3/1.5GBps for a disk, and 60,000/60,000 IOPS reading/writing for single disk to match all service scenarios
•Currently, Gen3 servers are used. One server is configured with 8/12 SSDs, with multiple NameSpaces and OSDs created.

Case Value

  • Excellent performance and long service life

    Union Memory's DSSD product adopted in the solution is equipped with intelligent algorithm to identify hot and cold data storage, optimize the GC storage mechanism, reduce write amplification, and achieve better performance and longer service life.

    Good user experience

    Union Memory's DSSD product adopts a dual-slope QoS mechanism to ensure normal performance and better user experience in extreme scenarios, such as when multiple service systems are running concurrently at a high speed.

    Easy maintenance

    Union Memory's DSSD product has a long service life to avoid business interruption and other losses caused by fake and inferior products, and reduce the storage maintenance frequency. This product also supports hot swap and violent swap, suitable for different maintenance methods, thus making the overall maintenance easier.
