Give the I/Os of Your Mission and Business Critical Apps the VIP Treatment They Deserve

By | DCIG Sponsored Analysis, Oracle, Storage Systems | No Comments

Features such as automated storage tiering and storage domains on today’s enterprise storage arrays go a long way toward making it feasible for organizations to successfully host multiple applications with different performance and priority requirements on a single array. However prioritizing the order in which data and I/Os are tiered is an entirely differently matter as organizations typically want the data and I/Os associated with their mission and business critical I/Os serviced ahead of lower priority applications. This is where the Quality of Service (QoS) Plus feature found on the Oracle FS1 comes into play as it does more than provide the “brains” behind its auto-tiering feature. It also re-prioritizes and re-orders application I/O according to each application’s business value to the enterprise.

The Emergence of the Economical, Massively Scalable Storage Array

By | Storage Systems | No Comments

Enterprise storage arrays offer just about every bell and whistle that an organization can possibly want. Whether it is compression, deduplication, a mix of flash and disk, all-flash, connectivity to the cloud, multi-protocol support – you name it, an array out there probably has it. Yet in the midst of all this feature functionality and options on storage arrays, storage arrays have somewhat lost their way in one respect as many are failing to deliver on arguably one of their basic tenets: plentiful amounts of storage that is cheap, highly available and highly reliable. This explains the emergence of a new class of economical, massively scalable storage arrays.

The Persisting Enterprise Reticence to Adopt Flash

By | Flash Memory, Hybrid, Solid State Storage Flash Memory, SSD Flash High performance, SSD Storage Systems, Storage Systems | No Comments

Flash is by all estimates the future of enterprise production storage with most enterprises anticipating a day in the not too distant future where they will use flash storage arrays (all-flash or hybrid) much more broadly within their data center. Yet despite flash’s many benefits (higher levels of performance, smaller data center footprint and reduced energy consumption among others,) many enterprises still only use flash in a limited capacity if they use it at all. Today I take a look at some of the factors that still contribute to an enterprise reticence to adopt flash more broadly.

Six Observations about Today’s High End Storage Arrays

By | Buyer's Guides, Fibre Channel, Storage Systems | No Comments

Enterprises investing in today’s high end storage arrays understand the value that these arrays offer in regard to their availability and performance as it can cost upwards of $5,000 for every minute that an application is offline. Applications and data must be available all of the time as any interruption in service can seriously impact a corporation’s revenue and reputation.

Oracle Brings out the Big Guns, Rolls out the FS1 Flash Storage System

By | Database, Flash Memory, Hybrid, Oracle, Solid State Storage Flash Memory, Solid state storage Flash Memory SSD, SSD, SSD Flash High performance, SSD Storage Systems | No Comments

Dedicating a single flash-based storage array to improving the performance of a single application may be appropriate for siloed or small SAN environments. However this is NOT an architecture that enterprises want to leverage when hosting multiple applications in larger SAN environments, especially if the flash-based arrays has only a few or unproven data management services behind it. The new Oracle FS1 Series Flash Storage System addresses these concerns by providing enterprises both the levels of performance and the mature and robust data management services that they need to move flash-based arrays from the fringes of their SAN environments into their core.

Four Factors Driving the Coming Resurgence of High End Storage Arrays

By | Storage Systems | No Comments

Beginning in the early 2000’s high end storage arrays began to lose some of their luster. While the EMC Symmetrix (now the VMAX,) HDS USP (now the VSP) and IBM Shark (now the DS8870) never technically fell out of favor, a new generation of midrange arrays had, at that time, matured to the point that organizations of all sizes began to deploy them as viable alternatives to these high end storage arrays. Now, 10 years later, specific features that can often only be found on high end storage arrays coupled with changes in organizational environments are driving the resurgence of these arrays.

What Will Be Hot in Flash in the Years to Come

By | Flash Memory, Solid state storage Flash Memory SSD, SSD, SSD Flash High performance, SSD Storage Systems, Storage Systems | No Comments

A couple of weeks ago I attended the Flash Memory Summit in Santa Clara, CA, where I had the opportunity to talk to a number of providers, fellow analysts and developers in attendance about the topic of flash memory. The focus of many of these conversations was less about what flash means right now as its performance ramifications are already pretty well understood by the enterprise. Rather many are already looking ahead to take further advantage of flash’s particular idiosyncrasies and, in so doing, give us some good insight into what will be hot in flash in the years to come.

10 Characteristics That Help to Define Today’s High End Storage Arrays

By | Fibre Channel, Networked Storage, Storage Systems | No Comments

It has been said that everyone knows what “normal” is but that it is often easier to define “abnormal” than it is to define “normal.” To a certain degree that axiom also applies to defining “high end storage arrays.” Everyone just seems to automatically assume that a certain set of storage arrays are in the “high end” category but when push comes to shove, people can be hard-pressed to provide a working definition as to what constitutes a high end storage array in today’s crowded storage space.

Oracle ZFS Storage Appliances Bring It All Together to Stand Apart from the Storage Crowd

By | Cloud Storage, DCIG Sponsored Analysis, Flash Memory, Hybrid, SSD, Storage Systems | No Comments

There is literally a divergence occurring right now in data storage solutions. On one hand, a number of storage providers seek to deliver highly differentiated storage solutions that work with a broad set of applications and operating systems. On the other, a few providers focus on delivering a storage solution that tightly integrates with one or more applications to deliver unparalleled levels of application performance and ease of management. The latest Oracle ZFS Storage Appliance ZS3 Series with its new OS8.2 provide the best of what both of these categories of storage systems currently have to offer to deliver a storage platform that truly stands apart.

Distinguishing Between the Multi-Tenancy and Virtual Storage Array Features on High End Storage Arrays

By | Storage Systems, Virtualization | No Comments

Organizations are becoming increasingly virtualized within their data center infrastructures which is leading them to aggressively virtualize the storage arrays in their infrastructure to complement their already virtualized server environment. As they do so, it behooves them to distinguish between, and have a clear understanding, of each virtual component that makes up their newly virtualized storage infrastructure. The need to clarify this terminology comes clearly into focus as organizations evaluate the multi-tenancy and virtual storage array capabilities found on many high end storage arrays.

The Challenges of Delivering Inline Deduplication on a High Performance Production Storage Array

By | Data Reduction, Deduplication, Flash Memory, Networked Storage, Solid state storage Flash Memory SSD, SSD, SSD Storage Systems, Storage Systems | No Comments

The use of data reduction technologies such as compression and deduplication to reduce storage costs are nothing new. Tape drives have used compression for decades to increase backup data densities on tape while many modern deduplicating backup appliances use compression and deduplication to also reduce backup data stores. Even a select number of existing HDD-based storage arrays use data compression and deduplication to minimize data stores for large amounts of file data stored in archives or on networked attached file servers.
