摘要： A method and apparatus are provided for protecting sensitive information within server or other computing environments. Numerous electronic requests addressed to a server system are received over network couplings and evaluated. The evaluation scans for sensitive information including credit card information and private user information. Upon detecting sensitive data, cryptographic operations are applied to the sensitive data. When the sensitive data is being transferred to the server system, the cryptographic operations encrypt the sensitive data prior to transfer among components of the server system. When sensitive data is being transferred from the server system, the cryptographic operations decrypt the sensitive data prior to transfer among the network couplings. The cryptographic operations also include hash, and keyed hash operations.

摘要： A method and system for securing network communications are provided. In a network a Secure Reverse Proxy (“SRP”) is placed among a server and a client where the client and SRP establish a secure connection using TLS protocol. Upon receiving a request from the client for a secure HTTP page, the SRP determines if the secure page is maintained in its cache. If the page is present, the SRP responds to the client by sending the requested secure HTTP page without contacting the server. If the page is not contained within the SRP's cache, the SRP establishes secure TLS connection with the server and forwards the request for the HTTP page. Receiving the HTTP page from the server, the SRP places it in its cache for future use. Having the page in its cache the SRP retrieves the page, encrypts it, and sends it to the requesting client. Subsequent requests for the same page do not involve the server enhancing the efficiency of network operations.

摘要： A NAS switch provides file migrations in a NAS storage network that are transparent to the clients. A source file server exports an original NAS file handles indicative of object locations on the source file server to the NAS switch. The NAS switch modifies the original NAS file handles to an internal file system and maps the original NAS file handles to a switch file handles independent of location. The NAS switch exports the switch file handles to a client. The client looks-up objects and makes NAS requests to the source file server using switch file handles. The NAS switch performs file migration by first replicating the namespace containing data to be migrated from source file server to a destination file server. Separately, the NAS replicates data which is a relatively longer process than the namespace replication. During data replication, namespace access requests for objects are directed to the replicated namespace. After data replication, file object requests for migrated objects are redirected to the destination file server in a process that is transparent to the client.

摘要： A NAS switch provides large file support to a file server in a decentralized storage network such as a NAS (Network Attached Storage) storage network. For example, files greater than 2-GB can be stored on a 32-bit commodity file server. The NAS switch sits in the data path of a client on the front end and a commodity NAS file server on the back end. A segmentation module in the NAS switch stores large files as separate data chunks in the file server. To do so, the segmentation module stores a directory file handle, which points to a directory containing the data chunks, in place of the large file. The segmentation module can also store a large file/chunk directory association in a migration cache. A reconstruction module processes client requests concerning large files by issuing requests to specific data chunks. For example, in a read operation, the reconstruction module calculates chunk numbers to determine which file to read and offsets to determine which byte to read within a chunk.

摘要： An object cache stores objects in a cyclic buffer to provide highly efficient creation of cache entries. The cache efficiently manages storage of a large number of small objects because the cache does not write objects into a file system as individual files, rather the cache utilizes cyclical buffers in which to store objects as they are added to the cache. Because of the use of a cyclic buffer, the high-overhead process of purging cache entries never needs to be performed. Cache entries are automatically purged as they are overwritten when the cyclic buffer becomes full and the input pointer wraps around from the end of a cyclic buffer to the beginning of a cyclic buffer. Additionally, in the event of a system crash or disk subsystem malfunction, inspect and repair time is independent of the size of the cache, as opposed to conventional file systems in which the time is proportional to the size of the file system.
摘要翻译：对象缓存将对象存储在循环缓冲区中以提供高效创建缓存条目。高速缓存有效地管理大量小对象的存储，因为高速缓存不将对象作为单个文件写入文件系统，而是缓存使用循环缓冲区来存储被添加到高速缓存中的对象。由于使用循环缓冲区，因此不需要执行清除高速缓存条目的高开销过程。当循环缓冲器变满并且输入指针从循环缓冲器结束循环到循环缓冲器的开始时，缓存条目被自动清除，因为它们被重写。另外，在系统崩溃或磁盘子系统发生故障的情况下，检查和修复时间与缓存的大小无关，与传统的文件系统相比，文件系统的时间与文件系统的大小成正比。

摘要： A NAS (Network Attaches Storage) switch authenticates a client on multiple file servers for proxy services. The NAS switch enables proxy services by successively authenticating the client on the file servers using referrals. The NAS switch further comprises a connection manager to establish connections to the client and the file servers, a referral manager to redirect the client for successive authentications, and a transaction manager to perform data transfers with the file servers on behalf of the client. The system components support DFS (Distributed File System), and communicate using a protocol dialect that supports referral mechanisms such as NFSv4 (Network File Server version 4) or CIFS (Common Internet File System). The transaction manager also performs a protocol dialect translation service when the connection manager negotiates one protocol dialect with the client, and a different protocol dialect with the file server.

摘要： A system and method for performing policy-based storage management using data related to access frequency and file attribute accumulation. A switch device provides transparency for transactions between a client and a storage network. The transparency allows objects (e.g., files or directories) to be moved (e.g., migrated) on the storage network without affecting a reference to the object used by the client (e.g., a file handle). A monitoring module generates accumulation data associated with the transactions for use in policy-based management. The accumulation data can describe uses of the file such as how often certain files are accessed, modifications to files such as creations of new directories or files, and other uses.

摘要： The present invention provides selective migration in a storage network in accordance with a policy. The policy can include rules that establish which objects are migrated from a source file server to a destination file server based on file attributes (e.g., file type, file size, last access time, frequency of access). For example, large multimedia files that consume I/O bandwidth on expensive or critical file servers, without adding much value to enterprise productivity, can be migrated to a commodity or less critical file server.
摘要翻译：本发明根据策略提供了在存储网络中的选择性迁移。该策略可以包括基于文件属性（例如，文件类型，文件大小，最后访问时间，访问频率）确定哪些对象从源文件服务器迁移到目的地文件服务器的规则。例如，在昂贵的或关键的文件服务器上消耗I / O带宽的大型多媒体文件，而不增加企业生产力的价值，可以迁移到商品或不太关键的文件服务器。
