我们的产品背后的专业技术
Cirrus Data已经开发了一种名为透明数据路径拦截（TDI，美国专利号8,255,538和8,417,818 – 点击专利选项卡了解更多）的技术。 TDI消除了在活动FC SAN上部署带内存储网关设备的所有困难。
TDI 技术是 Cirrus Data 所有解决方案的基础，为数据中心提供了极大的灵活性，以便执行迁移或添加缓存，而不必担心潜在的停机时间。 迁移数据或添加缓存解决方案不会使IT组织几个月才完成。 Cirrus Data 可以提供易于实施的解决方案，满足您的 SAN 迁移或 SAN 缓存需求。
使用TDI作为基础，CDS创建了 数据迁移服务器（DMS） 和数据缓存服务器（DCS），为现有SAN提供真正即插即用，无风险，零停机的数据迁移和数据缓存服务。 有几种可用的透明数据路径拦截插入方法，可以根据SAN环境要求和要迁移的客户端主机和LUN的限制进行使用。 所有插入方法都不需要客户端主机或存储器停机，也不会中断生产环境。
1. U.S. Patent No. 8,255,538: 系统及拦截存储卷数据的方法
这项 Cirrus Data Solutions 专利是强大的，全面保护CDS的透明数据拦截（TDI）技术。TDI是一种新颖和巧妙的发明涉及一种独特的架构和设计，它使用标准存储HBA端口建立一个透明的数据路径作为一种虚拟电缆。该技术提供了在主机和存储之间插入带内设备的性能，而不会造成停机，也无需对主机，交换机，和存储器更改。一旦连接，该设备自动发现每个目标存储端口的和主机启动端口的 WWPN，从而使其能够完全透明。其结果是一个真正的即插即用的技术，提供了一些解决方案的基础，包括数据迁移，数据缓存和数据复制。
2. U.S. Patent No. 8,417,818: 系统及拦截存储卷数据的方法
第二项 Cirrus Data Solutions 的专利延伸涵盖了TDI的发明，来增加存储协议， 如 iSCSI, SATA, Infiniband, and 其他。虽然 TDI 的具体技术细节可以从协议到协议各不相同，但是相同的透明数据通道插入的结果可以使用巧妙的手法通过这些现有的存储连接协议来实现，无缝地插入此“虚拟电缆”进入数据路径。最后，TDI 技术再次透明并悄悄地嵌入到生产环境中，因此相同期望的存储服务可以被添加到许多其他存储协议的现有存储配置中。
3. U.S. Patent No. 9,077,752: 系统，装置和方法，用于识别可由主机实体访问存储的数据，并提供数据管理服务
第二项 Cirrus Data Solutions 的专利延伸了 TDI 技术的主机端插入，覆盖了所有以前专利中的协议。另外，该专利还涵盖了vSAN，虚拟光纤交换机可用于增加扇入/扇出比率的地方。这增加了 Nexus 的效率，以允许一对多拦截，这意味着单个 Nexus 可以用来拦截多个链接。随着主机端的插入，和一对多的配置，单对 CDS 设备和少数的 Nexus 就可以用于拦截与一个大环境钟许多的存储链接。由这些链接提供的大量存储路径往往由于性能原因而不能呈现，而是由于简化冗余配置出现。通过透明地整合路径，该系统可以通过不降低性能，无截获风险，减少超过冗余路径地插入。
4. U.S. Patent No. 9,229,647: Systems, Methods, and Apparatus for Spoofing a Port of a Host Entity to Identify Data that is Stored in a Storage System and May be Accessed by the Port of the Host Entity
The fourth Cirrus Data Solutions patent extends the protection of the host side intercept technique, which allows selected interception of storage links and limits the scope of exposure. The enhanced technique provides greater flexibility and scope in supported configurations and topologies in enterprise storage environments. The added flexibility and control significantly increases the range and variety of applications using the intercept mechanism. In addition to data migration and centralized data caching, the technology can also be extended to data protection with backup, archiving, as well as malware detection, and possible data intrusion, thus making it possible to enable a complete line of advanced network storage functions.
5. U.S. Patent No. 9,298,390: Systems and methods for copying data maintained in a dynamic storage volume and verifying the copied data
U.S. Patent No. 9,298,390 is the 5th patent granted to Cirrus Data Solutions Inc. This invention is a mechanism implemented to dynamically track data images migrated for integrity verification. The Cirrus Data migration appliance performs data migration on a live production environment where the data continues to change during the migration process. The Cirrus Data migration operation is asynchronous, and is performed in a multi-pass manner. Time slots are customized for weekdays, weekends, or holidays, each with specified aggressiveness. This flexible migration system allows data to be migrated efficiently, yet with minimal impact to production traffic. The dynamic data image tracking mechanism is created to enable verification of the data under this kind of dynamic operating environment. With this invention, the migrated data can be verified whenever a consistent intermediate image is achieved, independent of the capricious nature of the source data as well as the potentially elaborate migration schedule, therefore ensuring the fidelity of the migrated data.
6. U.S. Patent No. 9,495,113: Systems, devices, apparatus, and methods for identifying stored data by a device located in a path between virtual Fibre Channel switches and performing a data management service.
U.S. Patent No. 9,495,113 is the 6th patent granted to Cirrus Data Solutions Inc. It covers the logical insertion technique for both host side and storage side configurations. With the logical insertion technique, storage links can be transparently inserted using switch commands either manually, or via the DMS insertion wizard. The current wizard supports most popular switch models, including Brocade and Cisco. Using the technique described in this patent, DMS appliances are inserted into active data paths without touching any physical cables in the storage environment. DMS appliances are simply connected into the production switches and logically inserted into data paths in a completely transparent manner, with zero disruption to the data I/O. Selected data volumes can then be migrated with minimal or no impact to production. This insertion technique also provides the most flexibility and scalability for planning and execution of mass data migration. In large environments, hosts can be selectively migrated, leaving the rest of the storage environment untouched an unaffected by migration.
7. U.S. Patent No. 9,542,120: Systems and methods for processing instructions while repairing and providing access to a copied volume of data.
U.S. Patent No. 9,542,120 is the 7th patent granted to Cirrus Data Solutions Inc. It covers the test view device method. During data migration, new destination LUNs are kept in a crash consistent state, which allows the application servers to test mount and review the data on the LUNs before the final cut-over occurs. During this time, the source and destination LUNs data differences are tracked, so each newly changed block in the source LUNs can be resynchronized to the destination LUNs as long as the LUNs are not yet cut-over. However mounting the intermediate images may change the data in the destination LUNs, which will disrupt the data relationship. The invention covered by this patent is a method to protect the destination data image while allowing unlimited access to the LUNs, ensuring the data relationship is maintained while the intermediate data images are reviewed and tested.
