IBM мейнфреймдерінің кластері
Cluster of IBM mainframes
Компьютерлік жүйелерде, Parallel Sysplex – z/OS жүйесімен бірлесіп, біртұтас жүйелік бейне ретінде жұмыс істейтін IBM мейнфреймдерінің кластері. Апаттық жағдайларда қалпына келтіру үшін қолданылатын Parallel Sysplex деректерді ортақ пайдалану және параллель есептеуді біріктіріп, 32 жүйеге дейін бар кластерге жоғары өнімділік пен жоғары сенімділік үшін жұмыс жүктемесін бөлісуге мүмкіндік береді.
In computing, a Parallel Sysplex is a cluster of IBM mainframes acting together as a single system image with z/OS. Used for disaster recovery, Parallel Sysplex combines data sharing and parallel computing to allow a cluster of up to 32 systems to share a workload for high performance and high availability.
Сервердің уақыт протоколы
Компьютерлік жүйелерде уақытты дәл сақтау маңызды. Мысалы, транзакцияларды өңдеу жүйесінде деректерді қалпына келтіру процесі журналдық файлдардан транзакция деректерін қайта құрайды. Егер транзакция деректерін тіркеу үшін уақыт белгілері қолданылса және екі байланысты транзакцияның уақыт белгілері нақты тізбектен ауысып кетсе, транзакция дерекқорының қайта құралуы қалпына келтіру процесінен бұрынғы күйге сәйкес келмей қалуы мүмкін. Серверлік уақыт протоколы (STP) бірнеше серверлер арасында бірыңғай уақыт көзін қамтамасыз ету үшін пайдаланылуы мүмкін. Желілік уақыт протоколының принциптеріне негізделген, HMC жүйесінің z серверлерінің бірін негізгі уақыт көзі (Stratum 1) ретінде белгілейді. Ол, әрі қарай, Stratum 2 серверлеріне байланыс арналары арқылы уақыт сигналдарын жібереді. Stratum 2 серверлері өз кезегінде Stratum 3 серверлеріне уақыт сигналдарын жібереді. Қолжетімділікті қамтамасыз ету үшін серверлердің бірін резервтік уақыт көзі ретінде тағайындауға болады, ал үшінші сервері Арбитр ретінде тағайындалып, төтенше жағдайларда резервтік уақыт серверіне негізгі рөлге өтуіне көмектеседі. STP 2005 жылдан бері System z серверлерінде қолжетімді. STP туралы толық ақпаратты "Server Time Protocol Planning Guide" нұсқаулығында табуға болады.
Maintaining accurate time is important in computer systems. For example, in a transaction processing system the recovery process reconstructs the transaction data from log files. If time stamps are used for transaction data logging, and the time stamps of two related transactions are transposed from the actual sequence, then the reconstruction of the transaction database may not match the state before the recovery process. Server Time Protocol (STP) can be used to provide a single time source between multiple servers. Based on Network Time Protocol concepts, one of the System z servers is designated by the HMC as the primary time source (Stratum 1). It then sends timing signals to the Stratum 2 servers through use of coupling links. The Stratum 2 servers in turn send timing signals to the Stratum 3 servers. To provide availability, one of the servers can be designated as a backup time source, and a third server can be designated as an Arbiter to assist the Backup Time Server in determining if it should take the role of the Primary during exception conditions. STP has been available on System z servers since 2005. More information on STP is available in “Server Time Protocol Planning Guide”.
Географиялық таралған параллельді сисплекс
Географиялық тұрғыдан таралған параллельді Sysplex (GDPS) – әртүрлі қалаларда орналасқан, мүмкін, параллельді Sysplex жүйесінің кеңейтілген нұсқасы. GDPS бір сайттық немесе көп сайттық конфигурацияларды қамтиды:
Geographically Dispersed Parallel Sysplex (GDPS) is an extension of Parallel Sysplex of mainframes located, potentially, in different cities. GDPS includes configurations for single site or multiple site configurations:
GDPS HyperSwap Manager: This is based on synchronous Peer to Peer Remote Copy (PPRC) technology for use within a single data center. Data is copied from the primary storage device to a secondary storage device. In the event of a failure on the primary storage device, the system automatically makes the secondary storage device the primary, usually without disrupting running applications. GDPS Metro: This is based on synchronous data mirroring technology (PPRC) that can be used on mainframes apart. In a two system model, both sites can be administered as if they were one system. In the event of a failure of a system or storage device, recovery can occur automatically, with limited or no data loss. GDPS Global XRC: This is based on asynchronous Extended Remote Copy (XRC) technology with no restrictions on distance. XRC copies data on storage devices between two sites such that only a few seconds of data may be lost in the event of a failure. If a failure does occur, a user must initiate the recovery process. Once initiated, the process is automatic in recovering from secondary storage devices and reconfiguring systems. GDPS Global GM: This is based on asynchronous IBM Global Mirror technology with no restrictions on distance. It is designed for recovery from a total failure at one site. It will activate secondary storage devices and backup systems. GDPS Metro Global GM: This is a configuration for systems with more than two systems/sites, for purposes of disaster recovery. It is based on GDPS Metro together with GDPS Global GM. GDPS Metro Global XRC: This is a configuration for systems with more than two systems/sites for purposes of disaster recovery. It is based on GDPS Metro together with GDPS Global XRC. GDPS Continuous Availability: This is a disaster recovery / continuous availability solution, based on two or more sites, separated by unlimited distances, running the same applications and having the same data to provide cross site workload balancing. IBM Multi site Workload Lifeline, through its monitoring and workload routing, plays an integral role in the GDPS Continuous Availability solution.

GDPS Continuous Availability: This is a disaster recovery / continuous availability solution, based on two or more sites, separated by unlimited distances, running the same applications and having the same data to provide cross site workload balancing. IBM Multi site Workload Lifeline, through its monitoring and workload routing, plays an integral role in the GDPS Continuous Availability solution.
GDPS HyperSwap Manager: This is based on synchronous Peer to Peer Remote Copy (PPRC) technology for use within a single data center. Data is copied from the primary storage device to a secondary storage device. In the event of a failure on the primary storage device, the system automatically makes the secondary storage device the primary, usually without disrupting running applications. GDPS Metro: This is based on synchronous data mirroring technology (PPRC) that can be used on mainframes apart. In a two system model, both sites can be administered as if they were one system. In the event of a failure of a system or storage device, recovery can occur automatically, with limited or no data loss. GDPS Global XRC: This is based on asynchronous Extended Remote Copy (XRC) technology with no restrictions on distance. XRC copies data on storage devices between two sites such that only a few seconds of data may be lost in the event of a failure. If a failure does occur, a user must initiate the recovery process. Once initiated, the process is automatic in recovering from secondary storage devices and reconfiguring systems. GDPS Global GM: This is based on asynchronous IBM Global Mirror technology with no restrictions on distance. It is designed for recovery from a total failure at one site. It will activate secondary storage devices and backup systems. GDPS Metro Global GM: This is a configuration for systems with more than two systems/sites, for purposes of disaster recovery. It is based on GDPS Metro together with GDPS Global GM. GDPS Metro Global XRC: This is a configuration for systems with more than two systems/sites for purposes of disaster recovery. It is based on GDPS Metro together with GDPS Global XRC.

GDPS үздіксіз қолжетімділік: Бұл екі немесе одан көп сайттарға негізделген апатты қалпына келтіру/үздіксіз қолжетімділік шешімі, олар шексіз қашықтықта орналасқан, бірдей қолданбаларды іске қосып, сайттар арасындағы жұмыс жүктемесін теңестіру үшін бірдей деректерге ие. IBM Multi-site Workload Lifeline жүйесі, оның бақылау және жұмыс жүктемесін бағыттау мүмкіндіктері арқылы GDPS үздіксіз қолжетімділік шешімінде маңызды рөл атқарады.
Geographically Dispersed Parallel Sysplex (GDPS) is an extension of Parallel Sysplex of mainframes located, potentially, in different cities. GDPS includes configurations for single site or multiple site configurations:
