StorNext File System

The highest performance is achieved by connecting to a StorNext cluster using StorNext client software. Apple machines may take advantage of the XSAN client built into MacOS. Windows and Linux machines require a simple code installation. StorNext clients connect in direct mode or proxy mode. For the fastest performance and lowest latency route to the storage, RDMA, FC SAN, and IB SAN clients connect directly to the storage network. LAN clients use proxy mode – gaining access to the shared storage through a proxy using a custom high-performance protocol.

NAS连接很简单，无需单独的客户端软件安装。在StorDext集群中，一个或多个节点可以被配置为NAS网关。NAS网关节点一起使用，提供自动负载平衡和故障转移，并支持SMB和NFS以实现通用连接。

一种StorNext Scale-out File Storage cluster may also act as a simple S3-compatible object store. Any S3-aware application or utility may be used to PUT and GET objects. Multiple object stores, projects, and buckets may be defined.

幸免makes StorNext self-protecting. FlexTier policies write files to secondary storage or cloud upon arrival, track copies and versions, and automatically offloads unused files from primary storage to make room for hot content. The Offline File Manager plug-in for Windows Explorer and Mac Finder gives end-users visibility and control over content location.

FlexSync是一种简单，高性能的工具，用于创建本地或远程副本，从单目录到完成文件系统。FlexSync是唯一可以保护所有Stordext的元数据的复制和同步工具，提供绝对的一对于One副本。

Every file system needs rules to ensure the equitable distribution of resources. StorNext supports quotas for managing and reporting on usage of both primary and secondary storage. User, group, directory, and project-level quotas provide a flexible structure. A system of soft limits, grace periods, and hard limits enables enforcement from simply reporting violations to blocking new data from being written.

Storage performance is a valuable resource. StorNext Quality of Service (QoS) rules enable administrators to control bandwidth allocation to clients based on their needs and priorities. Critical users can be guaranteed bandwidth, while other clients share the remaining throughput based on a hierarchical priority structure.

StorNext引入了两层抽象，可提供重要扩展功能。条带组通过聚合多个存储阵列并允许使用不同的访问模式分离数据来实现缩放文件系统性能和容量。

文件系统池最大限度地提高高性能存储的效用，并降低整体存储费用。池是StorNext文件系统中的可选的第二层抽象，并启用主存储分层，该主存储分层透明地移动不同类的主要存储等地之间的数据，例如NVME和HDD。

任何文件系统最重要的工作之一是确定在存储上放置文件的位置。分配是一个关键函数，因为它会影响性能。StorNext使用多种智能分配技术，包括乐观分配，a专利method known as Allocation Session Reservation, and a专利避免短写入读/修改/写入惩罚的方法。

文件系统元数据包括文件名，位置，时间戳，权限，标志和其他属性。这与内容元数据不同 - 艺术家，轨道号和比特率等内容。StorNext管理文件系统元数据，将内容元数据管理留给外部应用程序。元数据操作必须快速有效，因此它们不会阻止文件系统性能。为此，StorNext与文件数据分开地存储元数据，甚至可以通过单独的网络从数据流出元数据通信。一种专利压缩L2元数据缓存可确保所有或大多数元数据读取都来自RAM，以及专利buffering system accelerates metadata writes. Many additional patents cover advances in metadata communication and file system journaling. A custom,专利空间数据库用于归档所有元数据更改，无需扫描以检测到文件系统的更改。

Day-to-day administrative and monitoring tasks are easily accomplished using the StorNext web GUI.

Quantum’s optional Cloud Analytics console enables administrators to monitor all of their StorNext systems and Quantum tape libraries from anywhere. Quantum Service and Support provides proactive troubleshooting.

虽然网络GUI和CLI对日常行政活动有用Web服务API（WSAPI）是一个现代的、安全的连接应用接口吗cations to StorNext. Many量子技术合作伙伴亚博棋牌正网have integrated their applications with StorNext, using the WSAPI to gain information about StorNext’s internal state, or drive operations directly from their applications.

每个系统管理员都知道常用任务的自动化可以节省时间并减少错误，自动化意味着脚本。Stornext提供了全面的command-line interface (CLI)enabling administrators to script any action available in the GUI, and more. Scripts may be run ad-hoc or scheduled.
