Database Storage by Oracle

StorageTek Tape HelpfulHarmful Internal StrenghsWeakness Fast sequential data transfers More compact and lighter wieght than hard disk. Easy to use in a long-term investment protection SAM dramatically simplifies archiving by enabling archive managers to make business-level decisions about what data to keep, for how long, and on what cost structure, Long latency for random accesses It takes tens of seconds to load a cassette and position the tape head to an arbitrary place Tape storage requires a physical tape drive which can range anywhere from $1,400 to well over $12,000. The tapes themselves range anywhere from $30 to $90 per tape and these costs add up over time. External OpportunitiesThreats If every physical server had 3 SSD cards raided together for about 2 TB of protected, local cache? The chances of a cache miss plummet. If you are 99.99% accurate requesting data from cache, then you might be able to push that non-active data set to a tape-based library, with a small hard disk area Hardisk capacity > kryder's law - moore's law SSD is a newer technology and speeds are constantly increasing. Tape Capacity is not evolving fast enough Primary Source

SPARC HelpfulHarmful Internal StrenghsWeakness very aggressive price Not an engineering system : less robust, TCO higher, (Install & Configuration) External OpportunitiesThreats Very easy access Competitor less expensive ?

Oracle Engineered Systems HelpfulHarmful Internal StrenghsWeakness very aggressive price Not an dedicated option Not an option if data is increasing, because the value is not exactly in the datastorage role External OpportunitiesThreats Ready with flash, mix of plenty of technology with algorithms Supercluster Other dedicated system are much more relevant Oracle Exadata Database Machine – Oracle Database Appliance (ODA) – Oracle Exalogic Elastic Cloud – Oracle SuperCluster

Flash FS1 HelpfulHarmful Internal StrenghsWeakness architected to exploit the power of flash for greater performance predictability and better economics through automated tiering of flash and disk. rapid controller failover A SAN has normally his own network External OpportunitiesThreats QoS Plus : autotiering 1600 times more granular than competitive Price/Performance in a constant improvement NAS/SAN more & more blur, possible competition with ZFS SA

ZFS SA HelpfulHarmful Internal StrenghsWeakness aggressive price : available for mass market Hybrid Storage Pool architecture ensure that data remains safely stored on reliable and high capacity hard-disk without performance detriment. Massive DRAM cache, and software that optimizes its use, permit to be faster than flash disks. ZS3-2,a midrange enterprise multiprotocol storage system, ideal for use in performance-intensive workloads at an attractive price point ZS4-4: a high-end enterprise multiprotocol storage system for scalability Recognizes I/O patterns and automatically places data on the best of several tiers of storage media. Oracle Snap Management Utility for Oracle Database External OpportunitiesThreats Oracle ZFS Storage Appliance features an advanced set of management and analytics to manage, and troubleshoot storage in less time than is possible with competitors’ systems other separately licensed software features: remote replication, clones, encryption, and Oracle Snap Management Utility for Oracle Database Oracle Database workloads for data warehousing or mixed workloads can achieve a 10x to 50x reduction in their data volumes, and they can accelerate queries by 3x to 8x by using Oracle Hybrid Columnar Compression on ZFS Storage Appliance ZS3 Series, established worldrecord benchmark performance, while beating major competitors in price/performance a NAS can be integrated in every network OISP for ZFS Storage Appliances Competitor (HP) less expensive NAS/SAN more & more blur, possible competition with ZFS SAless expensive Primary Source

Storage Efficiency Optimization : Oracle Partitioning, Oracle Advanced Compression Option with new Heat Map and Automatic Data Optimization features, and Hybrid Columnar Compression (HCC), which is only available on Oracle Exadata, ZFS Storage Appliance, and FS1 Flash Storage Systems. With HCC, you can reduce your data warehouse storage footprint by 75 percent. Oracle Database Partitioning enhances the manageability, efficiency, performance, and availability of a wide variety of applications and enables a simple, yet very powerful, approach to Information Lifecycle Management Oracle Database Advanced Compression Option (ACO) provides a comprehensive set of compression capabilities to help reduce overall database storage footprints by enabling compression for structured and unstructured data, as well as backups. ACO automates what many DBAs do manually on a regular basis. Hybrid Columnar Compression (HCC) technology, a combination of both row and columnar methods for storing and compressing data in a logical construct called a compression unit. HCC can provide both compression and performance benefits with typical compression ratios of 12 times being achieved, so that entire rows of a database can be accessed in a single I/O operation. Oracle Intelligent Storage Protocol (OISP) is a unique communications protocol that enables Oracle Database 12c to communicate dynamically with the ZFS Storage Appliance to automatically tune critical factors, including logbias and record size, for optimal database performance. With OISP, storage administrators reduce manual tuning tasks by 65 percent. QoS Plus is a policy-based virtualization feature, incorporating business priority I/O (input/output) queue management fused with sub-LUN (logical unit number) automatic tiering into one simple management framework. Built on Oracle’s patented storage QoS technology, QoS Plus collects detailed information on your storage usage profile, evaluates data granules for movement to different storage tiers. Oracle Snap Management Utility for Oracle Database combines the underlying snapshot, clone, and rollback capabilities (only ZFS) Oracle’s StorageTek Storage Archive Manager 5.4 (SAM) dramatically simplifies archiving by enabling archive managers to make business-level decisions about what data to keep, for how long, and on what cost structure.

Logbias = a lot concerning stored data ? ???

OBIEE, Essbase, and Hyperion?

OBIEE = Reports & Dashboards for Transactionnal Analysis Essbase = What-is Analysis, Thinking, Cubes Hyperion = Financial, Operational & Strategic Planning BI = Understanding EPM = Improvement
