    Abstract: Technologies are described herein for providing a two-tier failover service. A request to access content by an application associated with an application identifier may be identified. A first record corresponding to the application identifier may be retrieved from a database information table. The first record may include a reference identifier, a database name of a database, and a failover value. A second record corresponding to the reference identifier may be retrieved from a server information table. The second record may include an indication of a first server computer as a primary server computer and an indication of a second server computer as a secondary server computer. A connection specification to either the first server computer or the second server computer may be generated based on the first record and the second record.

    Abstract: A technique for operating a high-availability (HA) data processing system includes, in response to receiving an HA logout indication at a cache, initiating a walk of the cache to locate cache lines in the cache that include HA data. In response to determining that a cache line includes HA data, an address of the cache line is logged in a first portion of a buffer in the cache. In response to the first portion of the buffer reaching a determined fill level, contents of the first portion of the buffer are logged to another memory. In response to all cache lines in the cache being walked, the cache walk is terminated.

    Abstract translation: 用于操作高可用性（HA）数据处理系统的技术包括响应于在高速缓存处接收到HA注销指示，启动高速缓存行走以定位包括HA数据的高速缓存中的高速缓存行。 响应于确定高速缓存行包括HA数据，高速缓存行的地址被记录在高速缓存中的缓冲器的第一部分中。 响应于缓冲器的第一部分达到确定的填充级别，缓冲器的第一部分的内容被记录到另一个存储器。 响应缓存中的所有缓存行被行走，高速缓存行走终止。

    Abstract: In certain embodiments, a tiered storage system is disclosed that provides for failover protection during data backup operations. The system can provide for an index, or catalog, for identifying and enabling restoration of backup data located on a storage device. The system further maintains a set of transaction logs generated by media agent modules that identify metadata with respect to individual data chunks of a backup file on the storage device. A copy of the catalog and transaction logs can be stored at a location accessible by each of the media agent modules. In this manner, in case of a failure of one media agent module during backup, the transaction logs and existing catalog can be used by a second media agent module to resume the backup operation without requiring a restart of the backup process.

    Abstract: A storage system has a RAID group configured by storage media, a system controller with a processor, a buffer memory coupled to storage devices and the processor by a communication network, and a cache memory coupled to the processor and the buffer memory by the network. A processor that stores first data, which is related to a write request from a host computer, in a cache memory, specifies a first storage device for storing data before update, which is data obtained before updating the first data, and transfers the first data to the specified first storage device. A first device controller transmits the first data and second data based on the data before update, from the first storage device to the system controller. The processor stores the second data in the buffer memory, specifies a second storage device, and transfers the stored second data to the specified second storage device.
