ISCSI Storage: Breaking Through the Barriers - Technology Brief
IP networks running the iSCSI protocol to connect servers with storage arrays present a compelling value proposition to enterprise technical architects. Consolidating competing network infrastructures into one and using a common skill set to manage both internal Ethernet and storage networks give enterprises motivation to continue to monitor the progress of iSCSI.
Intransa Opens its Platform - Product Profile
The battle for the SAN is on. FC SANs made serious inroads into the datacenter over the past five years but failed to gain much traction in the SMB space, primarily due to cost and management issues. Over the past two years, iSCSI, which was presented to the market as the simple and cost effective alternative to FC SAN, has been making accelerating headway into SMBs for applications below the mission critical tier.
Towards Unified Storage
Storage architectures are going through a fundamental change. Whereas we have seen most legacy players continue to offer traditional architectures that present a FC interface towards the host and either FC or SCSI, or more recently, SATA drives on the backend, newer players have developed iSCSI storage using grid principles and made the management of storage much easier. We have also seen players combine NAS and SAN in the same box.
Snap server S50
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 550 from Adaptec, we believe that the company is moving the Snap line into a critical transition point in price/performance and features. By leveraging the 64 bit AMD chip architecture with both a SAS/SATA and NAS/iSCSI option in a 1U form factor, this is a NAS box that can hold its own against most higher priced competition.
The value and benefits of IP SANs are clear and unchallenged. IP SANs leverage already ubiquitous Ethernet technology as the transport for delivering storage networking to a wider class of companies and applications than previously economically possible. As a result, companies without dedicated storage administrators or expensive Fibre Channel infrastructure have a viable alternative to direct attached storage.
The Small Medium Enterprise (SME) market is on the cusp of a significant storage infrastructure upgrade cycle. The current local and direct attach disk paradigm cannot persist indefinitely. Many of these SME firms are grappling with the same infrastructure challenges, such as data protection, disaster recovery planning, regulatory compliance, and consolidation that have buffeted the Global 2000 enterprises over the past five years. Yet, they are finding that the solutions used by those enterprises are too complex and costly for them to deploy.
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.
Adaptec Snap Server 700i
The Snap Server 700i is an iSCSI storage system with dedicated iSCSI, hardware RAID, and the OnTarget operating system providing a rich storage management feature set. The series does not replace the existing dual dialect NAS/iSCSI Snap Servers, but lets Adaptec take a hard charge at the growing marketplace of enterprise-level iSCSI SANs.
My colleague Jeff Boles and I recently attended the first EqualLogic User Conference in Dallas.
Dell Acquires EqualLogic
On November 5, 2007 Dell announced that it had entered into agreement to acquire iSCSI network storage vendor EqualLogic for $1.4B in cash. We believe that this investment by Dell is a clear indicator of the anticipated growth in the iSCSI market. This investment, while sizable, is well aligned with Dell’s strength in the small to medium business (SMB) market. Dell’s challenge will be to manage channel conflict with the EqualLogic VARs as well as resolve product positioning with its current OEM of EMC Clarrion storage. If Dell leverages this investment correctly this may turn out to be one of the most profitable storage acquisitions since EMC acquired DG (Clariion) back in 1999.
NetApp Refreshes Product Line
On November 9, 2010, NetApp refreshed a significant portion of their hardware and several key pieces of their software, along with adding a unified connect capability over 10GbE. New or enhanced software included a minor update release to Data ONTAP and a new OnCommand Management Suite designed to present a more holistic view of the infrastructure and make purchasing optional software easier. One of the key aspects of the new release of Data ONTAP 8.0.1 is that it includes inline compression capability applied across all protocols (NFS, CIFS, iSCSI, FCoE). This capability is in addition to the dedupe function that already has been shipping for several years.
Breaking Down the Barriers to VDI with Dell EqualLogic iSCSI SAN Arrays
While Taneja Group has been cautious to date on the pace of desktop virtualization adoption, recent hypervisor and storage technology innovations strongly suggest that in 2011 and 2012 we will see a rapid acceleration. Key to this momentum has been increased interest in one type of desktop virtualization, namely server-hosted virtual desktops (often called “virtual desktop infrastructure,” or VDI). VDI has often promised more than it delivered, however, due to complexity, performance and cost challenges. Chief among these challenges has been the high up-front capital costs and subsequent inefficiencies of the storage platforms deployed to support VDI. Dell aims to turn this around, however, with several recent additions and enhancements to its popular EqualLogic PS Series iSCSI array family. In this first section of a three-part in-depth report, we first review the current barriers to wider adoption of VDI, focusing on key storage challenges, and look at how the new Dell PS Series XVS hybrid SAS/SSD arrays deliver the density required to overcome these barriers.
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.
Maximizing Desktop Virtualization Success with VDI-optimized Dell EqualLogic Hybrid Arrays
VDI has often promised more than it delivered, due to stubborn complexity, performance and cost challenges. Chief among these challenges has been the high up-front capital costs and subsequent inefficiencies of the storage platforms deployed to support it. Building on deep integration with VMware’s vSphere 4.1 platform via the vStorage APIs, Dell has set its sights squarely on VDI and aims to break down both the cost of acquisition and TCO (CapEx and OpEx) barriers that have plagued VDI ROI in the past. Dell has added intelligent workload tiering and new hybrid SSD/SAS arrays to its Equal-Logic PS Series family and we analyze a recent performance benchmark to evaluate in detail how Dell’s innovations reduce complexity, improve performance and lower the cost of VDI.
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.
Maximizing Database Performance With Dell Equallogic Hybrid Arrays
Today’s combination of rapidly-accelerating demand for data and rapidly-consolidating datacenter infrastructure makes choosing the right storage for each of your business applications more important—and more difficult—than ever. In our view, it’s time more of this burden is taken on by the SAN itself. In other words, it’s time for more SAN intelligence. The intelligent SAN should optimize all available storage resources—automatically. In this profile explore how dynamic, multi-tiered OLTP workloads test the limits of traditional manual storage tiering strategies, and further strengthen the case for automated tiering on the SAN itself. Then we review Dell’s internal benchmark test results and speak to Carnival Cruise Lines, an EqualLogic customer, in order to evaluate how Dell’s hybrid SSD/SAS arrays are delivering higher performance and lower overhead both in the lab and in the field.
StorSimple – Storing data the right way
In this Taneja Group Technology Validation exercise, we put an innovative new array to the test to see just what was possible when a vendor stretches their wings and takes on much more than another version of storage done the same old way.
The vendor in this case is StorSimple, and what they propose is that a single storage system can do everything, while doing it more cost effectively, and with almost zero footprint in the data center. While that may sound like an almost unbelievable set of capabilities on the surface, what StorSimple has done is integrate cloud storage over the Internet behind a primary storage array for a truly unique set of capabilities. By coupling the two together, StorSimple unlocks infinite storage capacity, a small form factor, utter simplicity, and the tools to automatically protect data in place, forever. We anticipate this will hit home with a lot of customers – no more migration, no more backup, and built in DR finally makes storage seem like a technology that matches the needs of today’s business.
Join us in this Technology Validation report as we see if StorSimple’s promises hold true, and just what those promises look poised to do for today’s data center.
The case for Intelligent Storage (Dell)
In the past decade, a volatile business climate and a dynamic technology landscape have combined to raise the pressures on the enterprise datacenter, and especially on the storage infrastructure that underlies it. The need to adapt to such constantly-shifting demands and technology developments has sorely tested the limits of existing networked storage solutions. The virtualization mega-trend has dramatically changed the way information is sized, controlled, and protected. But traditional networked storage solutions are too often rigid, complex, and inefficient. Taneja Group has identified a way forward. We have collected the essential elements of the storage solutions needed for today’s new IT realities under the term “intelligent storage.” In this profile, we define what we mean by storage intelligence, whether that storage is file or block, and whether its architecture is SAN, NAS, or unified. We then examine how Dell is delivering this intelligence with its EqualLogic storage line. Wherever you are in your datacenter evolution, we think it’s time to examine whether your storage has the intelligence to carry you to your end goals.
Midrange Reinvented - the IBM Storwize V7000
In this Product in Depth, we take a look at the IBM Storwize V7000 and how it has harnessed a unique range of sophisticated heterogeneous storage virtualization technology from the IBM portfolio of intellectual property, and turned these technologies into building blocks for a next generation mid-range storage array. The result is a unique foundation to unify the consolidating and virtualizing infrastructure.
Client Virtualization the HP Way
What’s driving customers to bigger and bigger desktop virtualization initiatives? What are the challenges they face, and what can be done to resolve hurdles, and speed customers on their way to better client virtualization infrastructures that actually deliver the benefits that attract them to desktop virtualization in the first place?
No doubt, desktop virtualization, or “client virtualization” in HP parlance, roared off to a thunderous start, and the industry has already seen many big initiatives and offerings. Moving into 2012, client virtualization increasingly looks to have the wherewithal to go entirely mainstream, and move into a much broader set of customers than the initial high profile adoptees who had unusual business needs or were turning up unique hosted services. Yet client virtualization remains a complex undertaking. HP thinks they have a clear understanding of that complexity, and a consequent solution approach built to eradicate that complexity from the equation. In turn, they aim to make the promises of client virtualization more compelling than ever, and allow customers to be certain of realizing those promises. In this solution profile, Taneja Group will take a look at the promises driving client virtualization, the challenges that too often pull those promises apart, and then look at how HP is driving those challenges out of the equation with a newly announce product – VirtualSystem CV2.
