Oracle ZFS Storage Appliance 产品介绍说明书

Oracle ZFS Storage Appliance is flexible multiprotocol enterprise storage that delivers high performance, unmatched efficiency, and superior manageability for many types of workloads. For Oracle Database business intelligence/data warehousing (BIDW) workloads, Oracle ZFS Storage Appliance provides compelling performance and availability benefits. In addition, unique Oracle hardware and software co-engineering delivers performance, manageability, and efficiency advantages unavailable from other third-party systems. Using Oracle storage with Oracle Database directly empowers database administrators (DBAs) to efficiently manage and optimize the entire stack. Furthermore, by being co-engineered with Oracle Public Cloud, Oracle ZFS Storage Appliance offers a built-in cloud gateway for on-demand access to seamlessly take advantage of cloud capacity and economics.The Correct Tools for the JobOracle Exadata is the ultimate platform for Oracle Database from a performance and availability perspective. However, if you have consolidated workloads, heterogeneous vendors to support, flexible performance or availability requirements, or stringent cost constraints, an alternate solution is sometimes required. Oracle ZFS StorageAppliance, next-generation engineered storage, is just that solution due to its unique coengineering with Oracle software. This solution delivers special integrations that simplify management, reduce risk, and drive operational efficiencies.Like Oracle Exadata, Oracle ZFS Storage Appliance supports Oracle Database’s Hybrid Columnar Compression, a feature available only with Oracle Database 11g Release 2 and higher releases, when it is used exclusively in conjunction with Oracle storage systems. With multiple compression levels suitable for query and archival workload profiles, Hybrid Columnar Compression significantly enhances storage capacity utilization efficiency in many read-intensive Oracle Database data warehousing workloads. Because Hybrid Columnar Compression moves compressed data from the host to the storage, it actually uses bandwidth more efficiently and can result in higher throughput performance. In fact, customers accelerate critical BIDW queries an average of 8x. Additionally, Hybrid Columnar Compression can be used in conjunction with the Automatic Data Optimization feature of Oracle Database 12c to dynamically manage compression and storage tiering. This pairing helps you efficiently optimize partitioning for data footprint efficiency and query response performance O R A C L E O F F E R S P R O V E NS O L U T I O N S F O R O R A C L E D A T A B A S E P R I M A R Y S T O R A G E U S I N G T H EO R A C L E Z F S S T O R A G E A P P L I A N C EF O R B I D W W O R K L O A D S.C O N N E C T W I T H U S /oracle /oracle /oracle F O R M O R E I N F O R M A T I O N Contact: 1.800.ORACLE1 without manual intervention. This feature can be further enhanced by movingnoncritical data to the cloud and taking advantage of on-demand capacities in thecloud. For more information, please see the “Automatic Data Optimization with OracleDatabase 12c ” white paper.Superior BIDW PerformanceBIDW storage workloads are generally characterized by large-block-size high-throughput reads in response to query commands. From a performance perspective,the key requirement is high bandwidth throughput as opposed to high transactionalfrequency (that is, MB/sec is a priority over IOPS). Oracle ZFS Storage Appliancecombines a scalable storage operating system, high-throughput system design, andintelligent caching to deliver superior performance for just this type of workload. Plus,with all-flash and hybrid flash/disk configurations available, Oracle ZFS StorageAppliance delivers high performance at a lower cost —enabling betterprice/performance compared to competitive systems. For large and growing BIDWworkloads, this price/performance advantage is critical. For further information, pleasesee the “Realizing the Superior Value and Performance of Oracle ZFS StorageAppliance ” white paper. High Availability and Data ProtectionAside from performance, high availability is required in many BIDW environments sothat queries can continue to be served in the event of component failures. Oracle ZFSStorage Appliance offers high availability through dual-controller configurations withcontroller failover mechanism, drive failure redundancy, and network redundancyfeatures. Furthermore, the ZFS file system performs end-to-end checksumming andself-healing to ensure data integrity and prevent silent data corruption. Please see the“Architectural Overview of the Oracle ZFS Storage Appliance ” white paper for furtherdetails. Additionally, when the Data Guard feature of Oracle Database, EnterpriseEdition, is used in conjunction with Oracle ZFS Storage Appliance, a fullysynchronous, duplicate instance of the database can be maintained on a redundantsystem. This offers you the ultimate in-system or site-level outage protection with farless performance impact than traditional storage-based synchronous replicationsolutions. Oracle has documented best practices for tuning Oracle ZFS StorageAppliance for optimal performance and for availability by ensuring that database hostsdo not time out and applications continue running with zero data loss and minimaldisruption time.One of the compelling features of Oracle ZFS Storage Appliance is the ability to tunesettings for optimal performance and efficiency in different workloads. While diskmirroring is available for high transactional performance, single-parity RAID can beemployed in many throughput-oriented BIDW workloads for performance and spaceefficiency benefits. Also, share settings, including ZFS Intent Log (ZIL) behavior andblock sizes, can be tuned for different workloads, and for different conditions. Forexample, a share that contains a data warehouse compressed by Hybrid ColumnarCompression might optimally use a different record size than a share that contains anuncompressed data warehouse, and yet another record size would be used for othershares that are transactional in nature. Thus, unlike most storage systems from otherH Y B R I D C O L U M N A R C O M P R E S S I O N , U N I Q U E L Y A V A I L A B L E W I T H T H E C O M B I N A T I O N O F O R A C L E D A T A B A S E A N D O R A C L E S T O R A G E , C A N P R O V I D E U P T O 50XC O M P R E S S I O N I ND A T AW A R E H O U S I N G E N V I R O N M E N T S. Oracle ZFS Storage Appliance offers compelling benefits in an Oracle Database primary storage environment: • High availability • High performance in both transactional and BIDW workloads • Reduced management complexity costs at a lower upfront cost • Unprecedented integration with Oracle Database, such as Oracle Intelligent Storage Protocol and Hybrid Columnar Compression • Proven best practices used in Oracle I T’s own data centersC O N N E C T W I T H U S /oracle/oracle/oracle F O R M O R E I N F O R M A T I O N Contact: 1.800.ORACLE1vendors, Oracle ZFS Storage Appliance can be optimally tuned for a variety of distinctOracle Database workloads. To eliminate the tuning and guesswork required tooptimize these share parameters, Oracle ZFS Storage Appliance has exclusivecoengineering with Oracle Database 12c to dynamically automate this as abackground process. This unique technology feature of Oracle ZFS StorageAppliance, Oracle Intelligent Storage Protocol, can reduce administrative steps to tunedatabase storage by up to 65 percent. Oracle Intelligent Storage Protocol sends hintsfrom Oracle 12c and higher databases to Oracle ZFS Storage Appliance to optimizecritical storage resources without manual intervention, and it can actually prioritize I/Oto further improve performance by reducing resource contention. This can enableconsolidation of diverse database workloads on a single appliance by managing andoptimizing based on the specific incoming database I/O. See the “Oracle IntelligentStorage Protocol ” data sheet for more information. These database-awaretechnologies such as Hybrid Columnar Compression and Oracle Intelligent StorageProtocol result in much faster Oracle Database BIDW workload performance.Simplified ManagementOracle ZFS Storage Appliance also offers integration with Oracle Enterprise ManagerCloud Control. In addition to having its own Oracle Enterprise Manager plug-inavailable for single-pane-of-glass visibility of multiple appliances, Oracle ZFS StorageAppliance provides Snap Clone (a feature of Oracle Cloud Management Pack forOracle Database) integration with Oracle Enterprise Manager 12c and above toprovide database-as-a-service (DBaaS) capabilities. This is useful because it allowsadministrators to make space-efficient thin copies of entire data warehouses throughthe Oracle Enterprise Manager interface. When they use snap cloning, the copyoperation can occur much faster and occupy far less storage capacity than other copyoptions supported by most storage vendors. Snap Clone can be used in conjunctionwith the DBaaS schema provisioning functionality for rapid, low-storage provisioning ofdata marts for targeted analytical purposes.Further information on DBaaS and Oracle ZFS Storage Appliance integration usage isavailable in the “Delivering Database as a Service (DBaaS) using Oracle EnterpriseManager 12c ” white paper. Unique with Oracle ZFS Storage Appliance, thisfunctionality also can be paired with Hybrid Columnar Compression to deliver a highlycompact primary data warehouse footprint along with near-zero-initial-size data martsextracted from that small primary data warehouse. Such a setup can result insignificant savings in terms of storage footprint as well as enhanced performanceduring provisioning.In addition to integration with Oracle Enterprise Manager, it’s also important to havegranular insight into the storage itself in order to accurately tune and troubleshoot.Oracle ZFS Storage Appliance uniquely offers detailed drill-down, even to thepluggable database level, as a result of its co-engineering with the database. Theextended statistics available with the unique Oracle Intelligent Storage Protocoltechnology allows DBAs and storage administrators to resolve problems quicker withvisibility and correlations such as the help of AWR-like statistics made available on theappliance. Better visibility into the database-storage interaction replaces guessworkwith knowledge and confidence.C O N N E C T W I T H U S /oracle /oracle/oracle F O R M O R E I N F O R M A T I O N Contact: 1.800.ORACLE1 Oracle ZFS Storage Appliance offers multiprotocol support for Oracle Database. WhenOracle ZFS Storage Appliance is used in conjunction with Oracle Database 11g andhigher releases, the preferred protocol is Oracle’s Direct NFS Client —a high-performance NFS client feature built into Oracle Database. Direct NFS Client avoidsinefficiencies inherent in many OS kernel NFS implementations and achieves FC-likeperformance but with the simplified high availability and the infrastructure andmanagement cost characteristics of an enterprise Ethernet environment. For moreabout Direct NFS Client, please see the “Oracle Database 11g Direct NFS Client ”white pape.While Direct NFS Client is typically implemented over a 10 Gb Ethernet network, 40Gb InfiniBand is a connectivity option on Oracle ZFS Storage Appliance, making IPoIBwith Direct NFS Client a high-performance connectivity option. In addition, blockprotocols including iSCSI and FC are fully supported and widely used in cases whencustomers have a management preference for LUNs.Integration with Secondary Oracle Database StorageWorkloadsOne of the main benefits of using Oracle ZFS Storage Appliance for BIDW and otherprimary storage use cases is seamless integration with other Oracle Database storageworkloads. With built- in low-footprint snapshot and cloning data services, the primarydatabase can be quickly “copied” with little space and minimal overhead requirementsto meet development, test, or QA storage needs. Also, with built-in remote replicationplus best practices for Oracle Recovery Manager (Oracle RMAN) and Data Guard,Oracle ZFS Storage Appliance offers a number of options for both disaster recoveryand for backups integrated with development and test use cases that are fullycompatible with the primary database on Oracle ZFS Storage Appliance. Bestpractices for Oracle ZFS Storage Appliance are available for all of the followingsecondary workloads:» Backup using Oracle Database and Oracle RMAN» Disaster recovery using Data Guard» Provisioning development and test workloads from production, backup, or DRdatabases, including via the Snap Management Utility for Oracle Database featureof Oracle ZFS Storage Appliance (see the data sheet for more information)» Database consolidationConclusionAs engineered storage, Oracle ZFS Storage Appliance provides unique integrationswith Oracle Database to streamline management, provide superior efficiency, andaccelerate BIDW workloads in ways that are unobtainable by other vendors.Furthermore, Oracle ZFS Storage Appliance’s unique combination of a scalablestorage operating system, high-throughput system design, intelligent caching andflexible flash/disk/cloud configurations delivers the performance and availabilitycharacteristics needed for demanding mixed workload and BIDW environments.Oracle ZFS Storage Appliance is deployed by companies worldwide and proven inOracle’s own data centers, where Ora cle ZFS Storage Appliance is used for a varietyof database storage workloads.
