  3. 3. White Paper: Hitachi VSP G1000: A Strong Foundation for Oracle Environments 3 © 2014 by The Enterprise Strategy Group, Inc. All Rights Reserved. A Better Storage Platform for Oracle Conducting business today generates massive amounts of transactional, environmental, and operational data from customers and activities. Running a business today also requires massive amounts of data for deeper understanding of historical results, real-time insights, and future possibilities. Taken together, the management of data then forms a virtuous feedback loop, with the power to directly and positively influence strategy, accelerate innovation, and improve overall odds of success. However, management of data comes with its own challenges, which can impact the loop. Enterprises need a capable environment with which to handle the rigorous demands and unforgiving attitudes of customers, partners, and internal decision makers. Most often, this environment spans the range of IT, reaching to applications, databases, networks, security, servers, and storage. Very frequently the database of choice is Oracle, and a great deal of attention is paid to tuning the databases themselves for the best possible performance, availability, and functionality. Less often do IT staff fully appreciate the interconnections and interdependencies of the entire technology stack, perhaps a symptom of worker specialization and departmental organization around particular disciplines for each of the layers. One commonly overlooked dependency is the need for an optimal storage platform underlying everything else. Yet the choice of storage is critical to most of the important attributes of the Oracle environment. A list of the desired overall characteristics must include:  Low total cost of ownership and, therefore, potential for high ROI  High scalability, which is crucial for database environments  High performance, which is a prerequisite for the majority of Oracle “data servers”  Openness and flexibility, which are key both in terms of function (e.g., migrations) and heterogeneity  Minimal downtime, which is paramount due to the mission-critical nature of databases  Easy administration, which leads to cost savings and efficiency/productivity features that actually get used  Tight integration with multiple versions of the Oracle database, which almost (almost!) goes without saying The underlying storage will have a distinct impact on the outcomes for each of these areas. To better understand this point, this paper will look at how each attribute manifests problems to be managed, the resulting business impacts, and suggested best practices to resolve the issue. Following that will be a closer look at a particularly attractive choice for storage in large enterprise Oracle environments: Hitachi Virtual Storage Platform G1000 (VSP G1000). Challenges in an Enterprise Oracle Environment Enterprises will typically encounter a range of obstacles as they increase their reliance on Oracle as a central data repository for both transactional and analytic activities. These may be magnified by scale, meaning the larger the company, the larger the problems to be faced, and if unresolved, they can actually threaten core business operations. This section will explore some of the most common points of contention. The High Cost of Database Licenses A side effect of the explosive growth of data in business is the escalating cost to store, process, manage, and protect that data. As data proliferates and data-driven business becomes the norm with many more use cases and users, there is correspondingly more load on the server infrastructure to accommodate it. Often, different business requirements push to more databases as well. Online transaction processing (OLTP) workloads may be kept distinct from online analytics processing (OLAP) requirements, different departments or workgroups may want their own isolated instances, and testing and development may be separated from production until deemed ready for rollout. And mergers and acquisitions lead to a potentially more fragmented IT infrastructure, where often the roadblock to
  4. 4. White Paper: Hitachi VSP G1000: A Strong Foundation for Oracle Environments 4 © 2014 by The Enterprise Strategy Group, Inc. All Rights Reserved. integration is islands of homogeneous storage systems. There’s no point merging software, databases, and networks if the various types of “spinning rust” at the end of the wire are effectively speaking different languages! In a traditional relational databases environment, this issue may be further magnified by database software licensing costs that weren’t originally designed for the big data era. This per-database, per-node, per-core, and per- hard drive software licensing escalation places inordinate strain on the capital and operating budgets of many organizations. A recommended approach is to look for technologies that have resources to support and deliver higher server utilization. Many customers are seeking to consolidate databases to reach much higher average utilization levels, and being able to portably move databases without interrupting operations can be a huge benefit in this effort (this might mean not only non-disruptive migrations [long held as a key element in storage nirvana], but also an ability to manage heterogeneous storage devices from one central controller). As long as a robust governance model is in place to sequester sensitive data and control access appropriately, elements of this can be done quite satisfyingly with the right hardware choice…but the range of choices for suitable storage platforms is, frankly, not extensive. The Cost and Inefficiency of Legacy Storage at Scale As already noted, the technology stack must scale to meet new demands and data volumes. If the cost of database licenses is a serious challenge, it is often matched by the cost of the underlying storage. Most IT budgets aren’t growing fast enough to cover increasing storage demands, and this can lead to self-defeating policies on long-term data retention. While some data is kept to meet mandatory regulations and for record keeping, other useful data may be archived or permanently deleted in an attempt to control costs. Redundant data sets also complicate the issue, with the same data stored multiple times for different scenarios. Many legacy storage systems may not be designed to cost-efficiently handle this rapid data growth in Oracle database environments. An advisable solution is to explore storage systems that can offer the extreme scalability required by modern enterprises. The best arrays have architectural design characteristics and pricing models that make far more financial sense as data growth reaches new exponential heights. Again, consolidation of databases can be a high- impact strategy to reduce data redundancy and related costs, which is important as ESG research has found that 25% of respondents view managing data growth as one of their most important IT spending priorities.1 Just as much as raw capacity, there is a need for solutions with optimized resource utilization features built-in to provision smoothly and to cope with the demand of large databases. Support for storage technology should, as previously mentioned, preferably be heterogeneous in nature to match today’s heterogeneous IT infrastructures. Also, storage virtualization is a prerequisite to driving the levels of optimization that scalable and flexible Oracle environments demand if storage is to be anything other than an increasingly expensive anchor dragging down the advances in Oracle software capabilities. Storage virtualization enables everything from thin provisioning to replication, and ensures the optimum use of the storage resource (i.e., constrains cost). Slow Performance at Extreme Scale Today, data is generated by a wide range of users, applications, automated processes, and even machine sensors. This data often gets loaded directly (or sometimes indirectly) into Oracle databases for immediate transaction records or analytical needs. A major consideration is how well the databases and underlying infrastructure can handle the processing of this data ingestion, later extraction, or in-place querying. If the compute or storage resources are insufficient or inadequate for the various workloads, then overall system performance suffers. If system performance suffers, users are quickly dissatisfied and soon after, IT teams and database administrators hear complaints that they aren’t meeting the needs of the business. This is clearly unacceptable to anyone involved. Often, the slowest component of any database process is the I/O time, and this delay is multiplied when it exceeds storage system resources. To solve or avoid such circumstances, technology decision makers should seek out 1 Source: ESG Research Report, 2014 IT Spending Intentions Survey, February 2014.
  5. 5. White Paper: Hitachi VSP G1000: A Strong Foundation for Oracle Environments 5 © 2014 by The Enterprise Strategy Group, Inc. All Rights Reserved. storage platforms that achieve both radically higher performance and higher scalability than traditional offerings. One future-proofing approach is to select a platform that can be upgraded non-disruptively, increasing specifications with better hardware but without stopping business. Additionally, the well-integrated, judicious use of solid-state storage will actually be able to drive up performance and at the same time, drive down the average cost per GB/TB across the storage infrastructure; to serve growing database environments, this is a crucial balancing act. A Closed and Rigid Architecture Causes Its Own Problems Another area causing significant concern for companies with large Oracle environments is the issue of vendor lock- in. While it may be tempting to go with a much-hyped brand name offering, the proprietary nature and strict design specifications of these products can be limiting sometimes. No one ever wants to have to “rip and replace” a production system for changes to manage continuous data growth or technology enhancement curves. Nor is the prospect of paying premium prices for the privilege of upgrading a viable option. Sometimes, buyers will get stuck in a “boom and bust” cycle of deliberately over-provisioning, accepting low utilization rates, and then still running short for some databases before the next scheduled hardware refresh budget comes around. This is quite wasteful in terms of both administrative time and money. There is no doubt that the database will expand, so planning ahead to smoothly accommodate this growth is essential. While ESG has found that 52% of surveyed organizations expect their 2014 IT budgets for storage to increase, 2 this spend should be directed toward more open and flexible storage platforms. Organizations will want to select offerings that allow maximum utilization of the storage capacity as a whole, with the ability to pre-allocate sufficient space for all databases, and dynamically use capacity only as it is needed. Having functionality that assigns data to appropriate classes of storage in the system helps again with overall utilization efficiency and can ensure that the most frequently accessed data is stored on the highest performing storage technology. Not least, being able to expand and embrace not only local storage and networked storage but also “naturalized” storage can also give more options for different demands. Database Service Outages and Downtime The need to handle various configuration and infrastructure changes without impacting ongoing operations has been mentioned several times. This is no accident: Disruption of services and the corresponding lost business opportunities have a very real cost, though it is sometimes difficult to estimate precisely. Oracle databases may be very resilient and well-rounded from a management point of view, but they still require occasional care and tuning. This can be compounded if the supporting storage also needs planned downtime, as few DBAs or IT staff will perform a large number of potentially risky changes all at once. Add in the inevitable unplanned incidents, and total service availability often becomes a high-profile issue for the business executives. When selecting a storage platform, functionality that can deliver continuous availability should rank high on the evaluation criteria. While many vendors say they offer good results for mean time between failures (MTBF), redundancy, hot-swapping, and similar high-availability features, few come close to truly providing a zero- downtime foundation. Trouble Migrating Oracle Versions Oftentimes the bigger and more mission-critical an Oracle database is to the organization, the less often it is updated. Fears over mishaps due to software bugs or human errors push out service intervals on production systems, to the detriment of current capabilities. Yet choosing between out-of-date versions or business interruptions is not a good choice. Organizations need to be able to fluently support and migrate from popular and proven Oracle 9i, 10g, 11g, and 12c software versions and even complex RAC implementations, when it suits the 2 Source: ESG Research Report, 2014 IT Spending Intentions Survey, February 2014.

All Rights Reserved. application requirements, or they will fall behind in valuable features and potentially lag their competitors in development. The ideal storage platform would be able to ingest and serve up data without interruption, even as new versions of Oracle are tested and rolled into production. Simplified, customer-driven, non-disruptive online data migration is the best way to accomplish this goal, yet remains a rare (although, as we shall see, not unobtainable) feature because it can be extremely difficult to implement universally at the storage layer. Customers need storage that can not only accommodate multiple versions of Oracle simultaneously, but that is also tested and capable of supporting all the common Oracle database versions. Difficulty Integrating Storage and Database A final topic of concern for enterprise database developers and IT operations staff alike is the compatibility of their respective technologies. Skills specialization means that few architects can directly manage the entire stack and they will have to work together on design and process decisions. Yet this leads to more IT overhead and project delay, and a risk of error in communications of requirements. Generic storage is lacking in any connectivity to most common Oracle tools, such as Recovery Manager (RMAN), Automatic Storage Management (ASM), and the Enterprise Manager (OEM) including Cloud Control, and this implies a lot more custom scripting or even manual administration in order to handle regular frequency tasks. This obviously adds further cost and risk. Full, native support for Oracle tools—not just as a datasheet assertion, but proven in large, sensitive, real-world environments—should be considered mandatory for any storage system to be considered in “serious” Oracle environments. Customers would be wise to audit which extensions they use today or will need in the future and identify whether their storage can integrate directly with these, eliminating the multi-domain effort to recreate the necessary operational functionality. Hitachi Virtual Storage Platform G1000 Delivers in Oracle Database Environments So far, this paper has focused primarily on the most significant challenges faced by large enterprises in their Oracle environments, and general guidance on the optimal remedies for these issues. The remainder will examine Hitachi VSP G1000 to see how well it meets these needs. Prospective customers are urged to conduct their own technical and financial evaluations, but this review should help demonstrate the superior nature of the latest HDS product, even without providing a comprehensive description of all currently available features. Let’s start with the “basics” and then return to look at how VSP G1000 supports specific Oracle database user requirements. Even Oracle users cannot survive on software dazzle alone: VSP G1000 does not disappoint in the “specs” arena, delivering 4X the internal bandwidth, 3X the IOPS, and double the cache (up to 2 TB) capacity when compared with the previous VSP. And while Oracle database environments can be performance-hungry, VSP G1000 has plenty of “oomph”—it can deliver up to three million IOPS. This is key because storage I/O really matters to databases. Another key performance feature is the integrated flash acceleration and tiering. Hitachi has built an embedded flash memory controller, specifically for the most demanding workloads such as Oracle: Hitachi Accelerated Flash. It delivers greater performance with a lower price per gigabyte then commodity solid-state drives. Figure 1. VSP G1000 and Oracle
  7. 7. White Paper: Hitachi VSP G1000: A Strong Foundation for Oracle Environments 7 © 2014 by The Enterprise Strategy Group, Inc. All Rights Reserved. Turning from “horsepower” to “handling,” the key enabler of much of the functionality is the Storage Virtualization Operating System. It enables the complete separation of host and storage, regardless of connectivity, system type, location, or vendor, and creates a continuing storage infrastructure. Regardless of where the data is or what hardware it’s on, you get one view of all virtualized storage assets; imagine the power of that as databases are merged or integrated. Users can also logically group storage resources with the business applications (such as Oracle) that rely on them, making it easier to configure, report, replicate, and migrate when needed, without having to go searching for what goes with what. The system has almost an embarrassment of functional riches, but some that are useful, both generally to IT as well specifically to Oracle environments include:  Integrated active mirroring is a new capability that ensures you can provision and manage active-active clustered volumes up to 100 km apart. In other words, VSP G1000 turns a heterogeneous mix of storage into a distributed pool of virtual storage that can be spread over multiple data centers. Here VSP G1000 nicely complements Oracle RAC with the Global Active Device (GAD) functionality. This allows read and write I/O on mirrored volumes over distance while keeping data consistency, making it a great platform for Oracle RAC environments. For those with experience in the storage industry, this should sound familiar. HDS has been delivering heterogeneous storage virtualization for more than a decade. HDS has helped Oracle customers provide disaster recovery and migration between data centers over distances for years as well. So what's new and different about the active-active stretched cluster support that's built into the new VSP G1000 platform? Put simply, instead of managing remote mirrored copies of storage, VSP G1000 transparently maintains a single cache coherent copy that can be accessed from multiple data centers. Instead of relying on application-specific stretched clustering software that's implemented at the server layer, VSP G1000 does it transparently at the storage layer. Instead of the competitive approach of adding extra layers of hardware and software in an appliance to implement stretched storage clustering, Hitachi built it into VSP G1000. What are the practical implications of this valuable new technology in an Oracle database environments? The easiest to understand is the ability to non-disruptively migrate databases between data centers. It also simplifies hardware upgrades and enables faster disaster recovery. Less obvious is the ability to provide transparent access to a centrally managed database for users being serviced from multiple data centers.  Policy-based automation makes deployment and ongoing management faster and more efficient. It also makes it easy to dynamically align storage resources according to business needs, while maximizing ROI on storage. Without data silos and virtualization islands, an organization gets the agility to scale in whatever direction it wants, with whatever assets it wants, at whatever time and in whatever location it wants. This enables IT to focus on service delivery instead of infrastructure management, and enables continuity of operations with the least amount of complexity and disruption.  Unified management is a key part of VSP G1000, and is essential to keeping costs down, which matters whether you are running Oracle as much as anything else. If you can consolidate workloads to save on power and cooling of floor space, you need to consolidate management to reduce administrative overhead. Hitachi VSP G1000 platform has integrated Storage Navigator setup tasks into the consolidated Hitachi Command Suite console, bringing together setup and ongoing operations in one application. Consolidated user resource management and task lists reduce both OpEx and training costs. With global storage virtualization, Hitachi Command Suite does all the discovery and management across heterogeneous storage resources—HDS and other vendors—aligned by business groupings. Provisioning, monitoring, keeping storage attributes (like performance and cost) in sync with application requirements, and administering data protection is all done by Hitachi Command Suite, as is the tracking of storage usage and costs for chargeback/show back.  Non-disruptive data migration. Data migration has been one of the biggest pain points for IT, traditionally requiring downtime and cost, while exposing organizations to unwanted risk of data loss and service degradation. It’s typically been a cumbersome and disruptive activity, whether you do it yourself or get
  8. 8. White Paper: Hitachi VSP G1000: A Strong Foundation for Oracle Environments 8 © 2014 by The Enterprise Strategy Group, Inc. All Rights Reserved. professional services. With VSP G1000, data migrations can be executed transparently to the application using Hitachi Command Suite. This makes migrations faster and easier, while maintaining RPOs and RTOs for disaster recovery. Most everything is automated and driven from controller-based functionality (rather than the more typical appliance approach); while heterogeneous migrations are made much easier with the agnostic VSP, HDS-to-HDS migrations are completely non-disruptive…something that the owners of mission-critical Oracle databases everywhere will love. The result of these, and many other, capabilities is that VSP G1000 can help IT users in general—and demanding Oracle users in particular —deliver against both of the key parameters by which storage infrastructures are measured: performance and cost. Colloquially, this can be summed up as the ability to “do more for less”—in a more formal sense, it is the ability to service both the CIO and the CFO simultaneously by driving better ROI. This is currently, as the ESG research in Figure 1 demonstrates, the most-cited consideration in justifying IT investments. And VSP G1000 promises to deliver against the other top five most-cited considerations as well!3 Figure 2. Top Five Most Important Considerations in Justifying IT Investments Over the Next 12 Months Source: Enterprise Strategy Group, 2014. Much as Oracle workloads are part of the overall IT endeavor (and that integration and interconnectedness again make the choice of a powerful storage system important), we should return to looking specifically at the storage challenges of Oracle databases, and reflect as to how VSP G1000 fares. In priority order: 1. Reducing database costs is possible by targeting goals of both higher utilization and consolidation. VSP G1000 has greatly increased available resources because it is able to support three times the IOPS (>3,000,000), two times the cache (up to 2TB), four times the internal bandwidth (>800 Gb/s), and up to four times the processor cores (128.) of the previous generation of VSP. All of these enhancements will help to increase the power and responsiveness of databases, allowing for more work done by fewer total Oracle instances. The built-in, storage level, active-active clustering will enable the live migration of databases and workloads, making consolidation even easier to conduct in practice. 2. Massive scalability is readily provided with the increased capacities noted, plus a wide range of complementary features including Hitachi Dynamic Tiering (HDT), Hitachi Dynamic Provisioning (HDP), and 3 Source: ESG Research Report, 2014 IT Spending Intentions Survey, February 2014. 26% 31% 37% 37% 38% 0% 5% 10% 15% 20% 25% 30% 35% 40% Reduction in capital expenditures Improved security/risk management Business process improvement Reduction in operational expenditures Return on investment Which of the following considerations do you believe will be most important in justifying IT investments to your organization’s business management team over the next 12 months? (Percent of respondents, N=562, three responses accepted)
  9. 9. White Paper: Hitachi VSP G1000: A Strong Foundation for Oracle Environments 9 © 2014 by The Enterprise Strategy Group, Inc. All Rights Reserved. support for virtualizing heterogeneous storage. HDT is extremely valuable in being able to move data to the optimal storage type based on both usage patterns and cost, finding the most efficient way to deliver on requests. HDP is thin-provisioning software that lets the manager over-subscribe available space, ensuring room to grow without the waste of excess idle system capacity. Support for heterogeneous storage means legacy storage from different vendors can be used in conjunction with VSP G1000, again supporting the best possible mix for varying requirements and extending the useful life of existing storage systems. 3. Higher performance comes from the higher utilization, and of course from the increased IOPS, cache, and bandwidth that have been provided in the new system. The ability to conduct on-the-go hardware refreshes as specs continue to improve also ensures any near future technology developments, such as faster drives, can be quickly added to the platform. This all means VSP G1000 will have a longer effective lifecycle while still raising its performance profile as needed. 4. An open, flexible platform is made possible courtesy of features including dynamic tiering, thin- provisioning, and even a Hitachi NAS option for customers who want to run Oracle on NFS. Native functionality that includes being able to automatically allocate data and related workloads to the most appropriate type of storage, whether flash memory, solid-state state drive, or traditional disks, will be essential. Incorporation of other Hitachi storage systems, including HNAS, further extend the capabilities for consolidation, management, and delivery of file systems and applications. 5. Continuous availability, more than just high availability, comes from global virtualization, replication, snapshots, and resilient storage management. While server and database software has approached this full availability goal for some time, being able to manage it all at the storage level brings tremendous benefits independent of operating system or third-party storage virtualization software. Truly seamless operations should be possible through this virtualization at the data center, metro-area cluster, or, for some use cases, even worldwide distances. As mentioned, VSP G1000 has a customer-driven workflow-based non-disruptive migration capability that promises to reduce or eliminate scheduled downtime. 6. Oracle version support and upgrade without interruption is, again, delivered through the features mentioned and the distributed active-active stretch cluster. VSP G1000 supports all common Oracle database versions and has hooks to popular APIs. New Oracle versions can even be tested at length using live clones of real data, applications, and workloads, and can be swapped into production without disturbing live operations. 7. Oracle feature integration is brought by native connectors within VSP G1000 to Oracle ASM, RMAN, Oracle VM, and OEM Cloud Control, which gives identical touch points for the database team to interact with the underlying storage in ways that they already know and trust, with no new development required.
  10. 10. White Paper: Hitachi VSP G1000: A Strong Foundation for Oracle Environments 10 © 2014 by The Enterprise Strategy Group, Inc. All Rights Reserved. The Bigger Truth Hitachi VSP G1000, bringing active-active stretch clustering, extremely simple and heterogeneous migration, as well as even more performance and capacity, is an excellent option for enterprises requiring a powerful, efficient, and flexible storage platform for their most demanding Oracle workloads. Global virtualization at the storage level will be a big advantage with any application and over distance, reducing cost and complexity. But the solution is also especially valuable in globally congruent and integrated database operations. Virtual server machines revolutionized the way we provision and manage servers in the data center. With active- active stretched clustering that's built into the storage system, transparent to applications, and easy to manage from a single pane of glass, Hitachi has created virtual storage machines that revolutionize the way we provision and manage storage in, and between, data centers. While competitive offerings may meet some of the same requirements with an assortment of offerings, HDS has excelled in addressing them all from a single solution, delivering performance and non-stop availability in a cost- efficient package that is justifiably renowned for being “rock solid.” In a world that currently appears smitten with “software-defined” everything, it is worth pausing to remember that we have not yet managed to find a way to store data in the ether; consequently, users should not only demand extreme levels of functional sophistication from the storage in their Oracle environments, but should also equally demand an indisputably reliable hardware foundation. Hitachi VSP G1000 hits both targets soundly. A well-rounded, integrated technology approach like this is quite valuable in meeting the operational needs of storage, server, and database teams alike. ESG research findings support the need for solutions that combine these benefits and economics into one storage system.
