Modernize your Data Warehouse with FlashBlade

Modernize your Data Warehouse with FlashBlade

For a number of years, market analysts have been writing about the evolution of traditional data warehouses.  It started with the development of a scalable distributed file system for large distributed data-intensive applications (e.g., Google File System). It continued with new programming frameworks to support the processing and storage of extremely large data sets in a distributed computing environment (Hadoop, Spark, et cetera). And today (2017), we have large data warehouses using all-flash storage devices designed to replace spinning media, commonly used in enterprise storage arrays.

Even with these new developments, most market analysts agree the data warehouse, built upon a relational database, will continue to be the primary analytic database for storing much of a company’s core transactional data, such as sales transactions, customer data and financial records. These data warehouses will be augmented by big-data systems (data lakes). The data lakes are repositories for new sources of large volumes of machine-generated data such as: log files, social media data, videos and images. Furthermore, the data lake will be also used as a repository for more granular transactional data or older transactional data which is not stored in the relational data warehouse.

Even though this new information architecture consists of multiple physical data repositories and formats, the logical architecture is a single integrated data platform, spanning the relational data warehouse and the data lake.

How much is all this data worth? It seems like a silly question, until you recognize the financial valuations of companies that were built on data, like LinkedIn, Uber or Twitter. The value hidden in the data comes from being able to perform real-time, ad-hoc analytics, correlate data to various internal and external sources, and create a bridge between your data warehouse and data lake stores.

Data is the new business currency. Organizations continue to generate and store large volumes of digital data. It is estimated that between now and 2020, the global volume of digital data is expected to multiply another 40 times or more. Much of that new information will consist of personal details: where people have been, what products they’ve bought, what movies they like, which candidates they support—the list is nearly endless.

The volume, velocity and variety of data poses management and processing challenges. Starting with flexibility and scalability of the environment used to host it. The volume and velocity makes it difficult to ingest, store and optimally respond to both traditional transactional reporting and newer Big Data workloads. The data growth in source systems has an impact in loading and query performance.

Fortunately new architectures and technologies are changing the landscape of the modern data warehouse.  More powerful computing and all-flash storage platforms are available for increasingly lower costs. At the same time, relational database management systems (e.g., Oracle 12c, PostgreSQL and others) continue to evolve and provide new features to address some of the challenges mentioned above.

Also, modern hardware data platforms using all-flash arrays empower businesses to implement agile ways to obtain the information needed. It also enables the analytical capabilities that are a critical part of an organization’s digital transformation and competitive strategy.

Modernizing your data warehouse using this approach unifies data and its processing, despite being strewn across multiple platforms. Users can choose the best approach for a given data workload or analytic goal, plus offload certain workloads from the data warehouse to the data lake and vice versa. FlashBlade is uniquely powered to help solve the challenges of data warehousing, management, and analysis.

Oracle® on FlashArray//X: Scalable, Efficient and Fast

A great number of applications driving the enterprise are running on top of an Oracle® database. These applications, and the users that count on them, expect rapid response times. Pure Storage FlashArray//M accelerates operational databases and data warehouse solutions, through low-latency, high Input/output Operations Per Second (IOPS) and high throughput with minimum rack space usage and lower Total Cost of Ownership (TCO).

So, you might ask yourself what is left? Is it possible to reduce latency even more and gain additional performance? The answer is yes.

Meet the next radical innovation from Pure Storage: FlashArray//X. The first mainstream 100% Non-Volatile Memory Express (NVMe) enterprise all-flash array designed for the cloud era.

Screen Shot 2017-04-11 at 7.23.22 PMPure Storage has been using a software defined approach to connect flash. But there are always going to be choke points in the input/output (I/O) path from the application to the media.  The primary bottleneck has been the protocols (SAS, SCSI, SATA, et cetera) used to address storage on SSD.

SAS (based on the SCSI command set) and SATA (based on the ATA command set) are historic protocols developed for mechanical media. They do not have the characteristics to take advantage of the benefits of flash media.

So, the industry has come up with the NVMe standard. NVMe is a modern communications protocol designed specifically for flash storage systems.

The FlashArray//X is an expansion of the FlashArray product family and includes the following:

  • Screen Shot 2017-04-11 at 7.54.35 PMDirectFlash software – a module inside the Purity platform that uses global flash management at the system level. Typically, this flash management software would run inside each SSD.
  • DirectFlash modules – which use DirectFlash software to connect directly to raw flash. The modules make 100 percent of the flash in it accessible to the FlashArray//X70 Controllers, which enable NVMe communication.

The aim of the technology is to ditch performance bottlenecks that prohibit raw flash from being used and optimized efficiently.

Why is this important? High sustained latency in mission-critical applications can have a nasty compounding effect – for example, if the database can’t write to its redo log fast enough for a single write, everything stalls until that write can complete, then moves on. If this becomes a chronic condition, the user experience will be unacceptable as requests get piled up. FlashArray//X is the answer!

If you’re grappling with performance issues in your Oracle® environment, or simply trying to squeeze more performance out of existing servers, I’d strongly recommend start looking into how FlashArray//X can help you achieve that goal. The performance efficiency achieved by using NVMe will definitely contribute to speed up your Oracle® applications and databases. To learn more visit http://www.purestorage.com.
