All rights reserved. p. i DCIG 2010 MIDRANGE ARRAY BUYER’S GUIDE The Insider’s Guide to Evaluating FC and iSCSI Midrange Arrays Introduction This Midrange Array Buyer’s Guide represents the next generation of technology reports that I produced for many years when I wrote for Storage magazine (now part of SearchStorage.com). But it is also different in one major way: it reflects the behind the scenes evaluations that myself and many other engineers regularly did when I worked as a storage engineer for First Data Corporation. During the six years that I wrote for Storage magazine and the three (3) years since then that I have run and operated my own data storage focused analyst firm and website, I have contemplated how the technology reports that I used to write for Storage magazine could be made more thorough. Further, I wanted to leverage my experiences at First Data so the Buyer’s Guide could alleviate one of the most time consuming components of the midrange array buying decision – the information gathering and evaluation stage. In writing for both Storage magazine and now for DCIGinc.com, my intent was and is to inform users so they could make objective buying decisions on a specific technology. In this respect, the feedback that I receive from readers indicates that I have achieved a level of success. However the influence that I have on user buying decisions weighs on me, espe- cially when I considered the breadth of some of the technologies that I attempt to authori- tatively cover. Midrange arrays are a perfect example. When I started writing this Buyer’s Guide, I identified nearly 30 providers of midrange arrays that offered over 130 different models that were considered for inclusion in this Buyer’s Guide. Just coming up with that exhaustive list of storage providers and the models took some time. Then I still had to sort through each model’s hardware and software features and differentiate between them. While the differences between individual models were in many cases slight, differences do exist between each and every midrange array. So if I or anyone attempted to write a 5 – 7 page technology report that attempted to provide users with any meaningful guidance at all in regards to purchasing a midrange array, it would be incomplete. Just by the brevity of the report it would fail to take into account many of the criteria that are important when trying to develop a short list of products to consider for inclusion when making such an important buying decision. So this is what the first DCIG Midrange Array Buyer’s Guide does: It provides a much more comprehensive and in-depth look into as many midrange array models and their hardware and software features as possible. In preparing this Buyer’s Guide, I looked at these midrange array models and their features in much the same way as I did while writing for Storage magazine and working as a storage engineer at First Data Corporation: Through the eyes of an end user. During my stint at First Data, the storage team would create extensive lists of evaluation criteria for midrange arrays that included each model’s hardware and software features as well as the support offered by the storage provider. © 2010 DCIG LLC. All rights reserved. p. 1 DCIG 2010 MIDRANGE ARRAY BUYER’S GUIDE The Insider’s Guide to Evaluating FC and iSCSI Midrange Arrays Introduction continued Once these criteria were established, the team would go through and do a technical evalu- ation of each midrange array. At that time, we would try to clear up any ambiguities that existed (eg. a feature that was referred to by a different name by each storage provider), put heavier weightings on features that were more important to us and then score and rank each midrange array. Based upon these scores, First Data would then come up with 3 – 5 possible contenders for purchase and then submit that list to our procurement department to get competitive bids on each of those models. This Midrange Array Buyer’s Guide does this heavy lifting for end users. This Buyer’s Guide: • Lists each individual midrange array models by storage provider • Lists different midrange array features, whether or not they are supported and (where appropriate) how they are implemented • Weights these features according to what end users consider most important • Scores these features • Ranks each midrange array model The end result is that this Midrange Array Buyer’s Guide gives users the opportunity to do “at-a-glance” comparisons between many different midrange array models. Using these results, they can quickly come up with a short list of products that meet their specific needs and either go directly to a product evaluation stage with select midranges or even opt to get competitive bids on these products. Note that this Buyer’s Guide is not intended to be a substitute for bringing individual midrange arrays models in-house and testing them with specific applications. That function should still be done since every midrange array will perform differently under different appli- cation workloads. But it should help users get to that short list of products that they want to test much more quickly. I hope you find that this Buyer’s Guide meets this intended purpose in your environment.

But what that IDC number does not fully reflect is the growing impact that midrange arrays are having on organizations of all sizes and how much more money they are poised to spend on this particular category of external storage. The declining costs of storage capacity and network bandwidth coupled with their constantly improving performance are contributing to making external storage systems affordable and practical in all of these environments. However the introduction and rapid adoption of server virtualization is now making external storage almost a necessity in all size organizations. Among the types of external storage systems available, midrange arrays are the ones that are best positioned to benefit from this forthcoming wave of server virtualization. Today’s midrange arrays are affordable, easy to deploy, reliable, and offer high levels of performance. The only problem is that there are so many storage providers and midrange array models from which to choose that there is no way to make an objective buying decision since no analyst report or buyer’s guide has previously existed that could guide organizations through this maze to help them make a quick and informed buying decision.

By Jon Toigo hile touting “new,” flash-heavy “server-side” topologies and so-called “software-defined architec- tures” as evolutionary replacements for the “legacy” W SANs and NAS appliances that companies deployed in their previous refresh cycles, the industry continues to ignore the more fundamental drivers of storage inefficiency and cost: lack of management both of infrastructure and of data. 1 Storage Spectacular You would think from news reports that the storage industry was on its last legs. Vendor revenues from sales of everything from hard disk drives to external storage arrays, storage area networks (SANs) and network attached storage (NAS) appliances are either flat or declining ever so slightly. Seagate and Western Digital have hit a patch of dol- drums in which the trends of prior years—the doubling of drive capacities every 18 months and the halving of cost per GB every year—have frozen in their tracks. Even the redoubtable EMC, NetApp and IBM are experiencing purchasing slowdowns at customer shops that shouldn’t be happening if the capacity demand explosion that analysts say accompanies server virtualization is to be believed.

  • Real-Time Storage Tiering for Real-World Workloads
    Dot Hill Systems White Paper Real-Time Storage Tiering for Real-World Workloads Dot Hill Systems | Introduction 1 Dot Hill Systems White Paper INTRODUCTION The performance of many of today’s server-based applications is limited by the relatively slow input and output (I/O) to disk storage. A common way to mitigate this limitation and improve performance is to replicate active data from disks to higher-speed memory in a cache in servers and storage area networks (SANs). While caching content does help, it too has limitations, however. Caching primarily accelerates reads, and the size of the cache is normally only a small fraction of the disk capacity available. This makes it necessary to change the content constantly, and the algorithms employed to determine which content to cache may fail to deliver meaningful performance gains for critical applications. Advances in technologies have created a new layer or tier of storage between cache memory and traditional hard disk drives: the solid-state drive or SSD. SSDs use high-speed flash memory and offer capacities on a par with those of hard disk drives (HDDs). SSDs can be used either to create a very large cache (that substantially improves “hit” rates) or a very fast and full tier of disk storage. Either way, the performance gains can be significant for many applications. The purpose of this white paper, intended for both business and technical decision-makers, is to describe the use of flash memory in SANs, in general, and how Dot Hill Systems has implemented SSDs in its next-generation SAN.
