Adaptec Snap Server 650

The Snap Server product line has long been one of the most heralded workhorses of cost-effective NAS. With the most recent release of the Snap Server 650 from Adaptec, we believe that the company continues to move the Snap line into a critical transition point in price/performance and features.

Storing the virtual infrastructure - Block or File?

Are you deciding the fate of your virtual infrastructure, by way of whether it is destined to be built on top of block or NFS? We recommend you take a long term look at aligning your storage features with your management strategy.

NetApp SAN Efficiency

Storage efficiency is often bandied about in realms of archive and deduplication, but storage efficiency should be front and center when it comes to the golden tier of enterprise storage – primary storage. That is after all the most expensive storage resource in the data center. The problem is, few vendors have been able to do very much about storage efficiency without messing with the IOPs, raw throughput, low latency, and controller processing power that are the most precious components of enterprise storage. NetApp claims they think different here, and because they think different, they claim the storage architecture they’ve built - that delivers unified multiprotocol single system storage across the entire family of NetApp FAS systems - can deliver efficiency beyond the competition. In this Technology Validation, we took a FAS3270 infrastructure through a series of hands-on tests that made it clear that efficiency runs deep in the NetApp storage portfolio.

NexGen – Storage Control for the Virtual Data Center

In this Taneja Group Product Profile, we examine the challenges facing the data center architect when dealing with consolidating, ever-denser, next generation workloads. Clearly, the most difficult challenges show up in the storage layer. With this in mind, a new generation of storage array providers are coming to market, aiming to scale and provide more performance, in a denser footprint than ever before. But it takes more than just throwing IO at the problem, and NexGen has a unique approach that is poised to go further than ever before in solving problems around enterprise storage.

The HP Storage Portfolio – Building the Foundation for the Virtualized Infrastructure

Over the past couple of years, HP has executed an impressive number of storage acquisitions, and is systematically innovating around each of three key technologies – HP 3PAR, P4000, and their deduplicating StoreOnce. Perhaps nowhere are the synergies more clear than among the virtual infrastructure. In this Opinion, we’ll turn a critical eye toward these synergies, and render the Taneja Group perspective on whether HP is on the right path.

Selecting Exchange Storage Infrastructure-3 Critical Questions for the Selection of Microsoft..(IBM)

SELECTING EXCHANGE STORAGE INFRASTRUCTURE - 3 Critical Questions for the Selection of Microsoft Exchange Storage Infrastructure

Building ideal Microsoft Exchange storage infrastructures has always been an exercise in uncertainty and complexity. Uncertainty in terms of unknown future growth in both capacity and performance demands, and complexity because Microsoft Exchange seems to blossom in storage demanding features and capabilities with each new release. Worse yet, Microsoft itself can sometimes exacerbate the situation, by seemingly injecting Exchange with more storage features and speaking in veiled terms about the usefulness of external storage versus direct attached storage. To be certain, the demands from Exchange mandate something better than direct attached disk (DAS or DAD). In fact, Exchange demands more than run of the mill networked storage (NAS or SAN). In this solution profile, we’ll examine the fundamental pressures found in Exchange environments, and take a look at why it takes more than just capacity, and more than just performance.

The Dell FS7600 and FS7610 - Advancing unified, scalable storage

Unified storage – combined block and file storage from one system – has made serious inroads into customer datacenters over the past couple of years. It is little wonder, as it offers tremendous value and flexibility. Unified storage can serve up multiple types of data – both file and block – and help businesses support a wider number of storage demands from fewer better consolidated storage systems. The business in turn can increase storage utilization, simplify management of storage, and deliver storage services that are both more cost efficient and agile.

But despite these benefits, a historic compromise has often faced the unified storage customer. Unified storage systems were often highly capable, but lagged behind the most recent storage innovations in at least two key dimensions – adaptability and easy to use unified management. In terms of adaptability, the underlying architecture of many of these systems often made next generation capabilities like simultaneous performance and capacity scaling much harder to implement. In terms of management, these systems often fell short of allowing typical administrators to easily manage the increased functionality delivered by a unified system. 

In 2011, Dell announced the pairing of FS7500 NAS controllers with their family of EqualLogic iSCSI storage arrays – a solution set designed to unleash a new level of adaptability in unified storage. The FS7500 was no paltry piece of add-on equipment – it was in fact built for a considerable amount of performance that could make full use of big eight-array EqualLogic storage pools, which could contain up to 384 of the fastest disks on the market. Moreover, the FS7500 came with another powerful ingredient: when paired with EqualLogic storage, the combined system retained all of the classic EqualLogic scale-out capability (within the underlying iSCSI storage) while the FS7500 was itself also scalable, easily going from 2 to 4 controllers. 

This meant for the first time, the small and medium enterprise (SME) customer could purchase a truly scalable unified storage system from a major vendor – a system that could start small, and grow with them as their business needs changed over time. Just as importantly, these systems were nicely integrated. An FS7500 continued to leverage all of the SME-empowering management functionality within Dell’s class-leading (and free) Group Manager and SANHQ storage management tools, which are the same tools used to manage the iSCSI storage. We previously reviewed the FS7500 storage system in a hands-on Technology Validation exercise, available here.

Recently, Dell announced an update to the EqualLogic-paired FS family – the EqualLogic FS7600. To be clear, other Dell products exist based on the same underlying FS technology – Fluid FS – including the Dell MD storage-integrated NX3600 and the Dell Compellent storage-integrated FS8600. But with an eye toward our findings in our original FS7500 Technology Validation exercise, we were keenly interested in how the FS7600 may have advanced in a relatively short period of time since the FS7500 hit the market. This was all the more intriguing because Dell EqualLogic has long excelled in rapid storage capability innovation. A closer look revealed an all-new hardware architecture, the addition of several key storage capabilities, and some claims about performance improvements. In this Product Brief, we will examine the FS7600, and evaluate how well Dell has advanced capabilities and tackled some of the challenges in its first generation FS7500 NAS.
