Run Silent, Run Deep, Run StorNext

海军与StorNext的1,000倍数据增加

When the U.S. Naval Surface Warfare Center’s Carderock Division (NSWCCD) upgraded its underwater sensor array, it required a storage system that could keep up with the 1,000-fold increase in data. NSWCCD stayed with Quantum’s StorNext data management software.结果：A scalable, reliable solution that significantly increased performance.

Reliability, Capacity Critical

NSWCCD在美国海军的许多研究活动中，NSWCCD管理了来自阿拉斯加实验室的两个先进的水下传感器阵列。这些阵列在海上和潜艇静止时收集潜艇的声学签名。此信息用于评估漏洞并开发静止措施。

When NSWCCD deployed new sensor arrays, each containing hundreds of underwater microphones, they increased data collection by a factor of 1,000, with an average of 550,000 data files and up to 3TB of data per test. All of that data needed to be accurately captured and stored during the three to twenty minutes that a test takes. If a problem was found with the data quality, tests could be rerun, but only at the significant additional cost of recalling submarines or delaying their departure.

A SAN installed in 2005 that utilized an earlier version of Quantum’s StorNext File System initially met the organization’s needs. With the new volume of data, NSWCCD’s computer scientist Bryan Bennett went looking for a high-speed, high-availability storage system. The best choice, he quickly realized, was to upgrade StorNext.

Benefit: Ability to Process More Data Quickly

NSWCCD现在能够处理更多的数据，而不是使用新的批量存储系统，其中包括三个StorNext文件系统。StorNext的高速文件共享和可扩展的SAN性能使得传感器产生的丰富详细信息的分析能够分析。

使用第一文件系统集中于高速数据摄取，第二文件系统提供了数据的合并和分析。在以前的系统架构中，一切都被写入单个分区，因为文件系统填满了速度较慢，更可靠。最后，由于仅处理数据存储在第三文件系统中，所以原始数据在第二文件系统中保持不变，以备将来的分析。当系统为NSWCCD最大的测试完美操作时，该设置的好处是显而易见的。

“当我们意识到我们可能比我们通常在一天中做更多的数据占用50％的数据，我们很惊讶，”贝内特说。“与强大的数据管理系统耦合的更快的摄取数据速率使我们能够更快地运行测试，并及时将船舶返回海。StorNext的性能收益非常令人印象深刻的管理。“
