The NOSQL database to support data and high concurrent read and write,scalability and high availability features in a distributed storage system which has been applied widely. In this paper, through the research of load balancing in distributed storage system,and it proposes the consistent hashing algorithm and the virtual node strategy, in order to improve the load balancing of the system and increase the cache hit ratio. For the load balancing principle of NOSQL and SQL Server, analysis and comparison of the experimental data.The result shows that, with the increase of the number of virtual nodes, the cache hit ratio of NOSQL is higher than the cache hit ratio of SQL Server.

In this paper, an extensible system prototype of cloud storage is designed. Considering the load balance of cloud storage system, an improved data storage strategy based on consistent hashing algorithm is proposed in this paper. The strategy adopts virtual nodes to storage data and real–time monitoring of load rate of each storage node to adjust load balancing of the whole storage system. In the improved strategy, the priority is introduced into the storage system to rapidly improve the utilization rate of the new storage nodes. The strategy can effectively optimize the performance of the whole storage system, and improve the overall effect of the load balancing.

<p><em>Distributed Storage System </em>(DSS) memiliki sejumlah perangkat server penyimpanan yang terhubung dengan banyak perangkat <em>switch</em> untuk meningkatkan utilisasi jaringan. DSS harus memperhatikan keseimbangan beban pada sisi server penyimpanan dan trafik data pada semua jalur yang terhubung. Jika beban pada sisi server penyimpanan dan trafik data tidak seimbang, maka dapat menyebabkan <em>bottleneck network</em> yang menurunkan utilisasi jaringan. Kombinasi <em>server</em> dan <em>link</em> <em>load balancing</em> adalah solusi yang tepat untuk menyeimbangkan beban pada sisi server penyimpanan dan trafik data. Penelitian ini mengusulkan metode kombinasi algoritme <em>least connection</em> sebagai metode <em>server</em><em>-load balancing</em> dan algoritme <em>global first fit</em> sebagai metode <em>link</em><em> load balancing</em>. Algoritme <em>global first fit</em> merupakan salah satu dari algoritme <em>load balancing</em> <em>hedera</em> yang bertujuan untuk menyeimbangkan trafik data berukuran besar (10% dari <em>bandwidth</em>), sehingga terhindar dari permasalahan <em>bottleneck network</em>. Algoritme <em>least connection</em> merupakan salah satu algoritme <em>server</em><em> load</em><em> balancing</em> yang menggunakan jumlah total koneksi dari server untuk menentukan prioritas server. Hasil evaluasi kombinasi metode tersebut didapatkan peningkatan pada rata-rata <em>throughput </em>sebesar 77,9% dibanding hasil metode <em>Equal Cost Multi Path </em>(ECMP) dan <em>Round robin </em>(RR). Peningkatan pada rata-rata penggunaan <em>bandwidth</em> sebesar 65,2% dibanding hasil metode ECMP dan RR. Hasil Penggunaan <em>CPU</em> dan <em>memory</em> pada <em>server</em> di metode kombinasi ini juga terjadi penurunan beban <em>CPU</em> sebesar 34,29% dan penurunan beban penggunaan <em>memory</em> sebesar 9,8% dibanding metode ECMP dan RR. Dari hasil evaluasi, penerapan metode kombinasi metode <em>server</em> dan <em>link load balancing</em> berhasil meningkatkan utilisasi jaringan dan juga mengurangi beban server.</p><p> </p><p><em><strong>Abstract</strong></em></p><p class="Judul2"><em>Distributed Storage System (DSS) has a number of storage server devices that are connected to multiple switch devices to increase network utilization. DSS must pay attention to the balance of the load on the storage server side and data traffic on all connected lines. If the load on the storage server side and data traffic is not balanced, it can cause a network bottleneck that reduces network utilization. The combination of server and link-load balancing is the right solution to balance the load on the server side of storage and data traffic. This study proposes a combination of the least connection algorithm as a server-load balancing method and the global first fit algorithm as a link-load balancing method. The global first fit algorithm is one of Hedera's load balancing algorithms which aims to balance large data traffic (10% of bandwidth), so as to avoid network bottleneck problems. Least connection algorithm is one of the server balancing algorithms that uses the total number of connections from the server to determine server priority. The results of the evaluation of the combination of these methods showed an increase in the average throughput of 77.9% compared to the results of the Equal Cost Multi Path (ECMP) and Round robin (RR) methods. The increase in the average bandwidth usage is 65.2% compared to the results of the ECMP and RR methods. The results of CPU and memory usage on the server in this combination method also decreased CPU load by 34.29% and a decrease in memory usage load by 9.8% compared to the ECMP and RR methods. From the evaluation results, the application of a combination of the server method and the link load balancing method has succeeded in increasing network utilization and also reducing server load.</em></p><p><em><strong><br /></strong></em></p>
