Advanced PCI Express and Stargen

PCI Express is rapidly becoming the interconnect standard of choice for designers of storage, servers and communications equipment worldwide. More recently, the PCI Express specification was enhanced by defining a transaction layer above the physical and the media layers defined by the original standard. Known by most designers as ASI for its defining body, the Advanced Switching Interconnect Special Interest Group (ASI-SIG), the new standard adds I/O virtualization, high availability and support for multiple CPUs, along with a host of other sophisticated features to the base standard, while maintaining 100% compatibility.

Fibre Channel: The Proven and Reliable Workhorse for Enterprise Storage Networks

Mission-critical assets such as virtualized and database applications demand a proven enterprise storage protocol to meet their performance and reliability needs. Fibre Channel has long filled that need for most customers, and for good reason. Unlike competing protocols, Fibre Channel was specifically designed for storage networking, and engineered to deliver high levels of reliability and availability as well as consistent and predictable performance for enterprise applications. As a result, Fibre Channel has been the most widely used enterprise protocol for many years.

But with the widespread deployment of 10GbE technology, some customers have explored the use of other block protocols, such as iSCSI and Fibre Channel over Ethernet (FCoE), or file protocols such as NAS. Others have looked to Infiniband, which is now being touted as a storage networking solution. In marketing the strengths of these protocols, vendors often promote feeds and speeds, such as raw line rates, as a key advantage for storage networking. However, as we’ll see, there is much more to storage networking than raw speed.

It turns out that on an enterprise buyer’s scorecard, raw speed doesn’t even make the cut as an evaluation criteria. Instead, decision makers focus on factors such as a solution’s demonstrated reliability, latency, and track record in supporting Tier 1 applications. When it comes to these requirements, no other protocol can measure up to the inherent strengths of Fibre Channel in enterprise storage environments.

Despite its long, successful track record, Fibre Channel does not always get the attention and visibility that other protocols receive. While it may not be winning the media wars, Fibre Channel offers customers a clear and compelling value proposition as a storage networking solution. Looking ahead, Fibre Channel also presents an enticing technology roadmap, even as it continues to meet the storage needs of today’s most critical business applications.

In this paper, we’ll begin by looking at the key requirements customers should look for in a commercial storage protocol. We’ll then examine the technology capabilities and advantages of Fibre Channel relative to other protocols, and discuss how those translate to business benefits. Since not all vendor implementations are created equal, we’ll call out the solution set of one vendor – QLogic – as we discuss each of the requirements, highlighting it as an example of a Fibre Channel offering that goes well beyond the norm.

Oracle FS1 Throws the Gauntlet Down Against EMC

Oracle announced Oracle FS1, its first all-flash storage offering on September 29th at Oracle World. While there is much to study under the covers (which we will do in the next few weeks) it is clear that Oracle has thrown the gauntlet down against all-flash-array vendors, especially EMC and its XtremIO offering. There are essentially five things of importance with FS1. One, while it can be deployed as a true all-flash array, it is really designed as a hybrid, albeit with a flash-first engineering philosophy. Two, it is designed with four tiers, namely Performance SSD, Capacity SSD, Performance HDD and Capacity HDD. These four tiers are mapped to five QoS layers that are associated with application priority. This management framework is called QoS Plus. Three, the granularity of data movement between tiers is 640KB, compared to 1GB for EMC VNX1, 256MB for EMC VNX2 and HP 3PAR. Oracle claims for database workloads granularity matters and 640KB is much closer to ideal compared to larger chunks. Four, provisioning storage for Oracle and non-Oracle applications can be done with one click with FS1 Application Profiles that provide pre-defined and pre-tuned best practices storage profiles. Five, other Oracle differentiators, such as Hybrid Columnar Compression (HCC) and other data services available on existing Oracle systems are all available on FS1 and they are almost all free. According to Oracle, a single rack of FS1 compared to a 2-node version of EMC XtremIO configuration yields advantages in favor of FS1 of between 1.2X to 9.7X, along the dimensions of max capacity, read IOPS, write IOPS, 50/50 R/W IOPS, read GB/s and write GB/s, with the differences being huge in the sequential throughput dimension. Let’s look at these five elements in a little more detail below.

Enterprise Flash - Scalable, Smart, and Economical

There is a serious re-hosting effort going on in data center storage as flash-filled systems replace large arrays of older spinning disks for tier 1 apps. Naturally as costs drop and the performance advantages of flash-accelerated IO services become irresistible, they also begin pulling in a widening circle of applications with varying QoS needs. Yet this extension leads to a wasteful tug-of-war between high-end flash only systems that can’t effectively serve a wide variety of application workloads and so-called hybrid solutions originally architected for HDDs that are often challenged to provide the highest performance required by those tier 1 applications.

Someday in its purest form all-flash storage theoretically could drop in price enough to outright replace all other storage tiers even at the largest capacities, although that is certainly not true today. Here at Taneja Group we think storage tiering will always offer a better way to deliver varying levels of QoS by balancing the latest in performance advances appropriately with the most efficient capacities. In any case, the best enterprise storage solutions today need to offer a range of storage tiers, often even when catering to a single application’s varying storage needs.

There are many entrants in the flash storage market, with the big vendors now rolling out enterprise solutions upgraded for flash. Unfortunately many of these systems are shallow retreads of older architectures, perhaps souped-up a bit to better handle some hybrid flash acceleration but not able to take full advantage of it. Or they are new dedicated flash-only point products with big price tags, immature or minimal data services, and limited ability to scale out or serve a wider set of data center QoS needs.

Oracle saw an opportunity for a new type of cost-effective flash-speed storage system that could meet the varied QoS needs of multiple enterprise data center applications – in other words, to take flash storage into the mainstream of the data center. Oracle decided they had enough storage chops (from Exadata, ZFS, Pillar, Sun, etc.) to design and build a “flash-first” enterprise system intended to take full advantage of flash as a performance tier, but also incorporate other storage tiers naturally including slower “capacity” flash, performance HDD, and capacity HDD. Tiering by itself isn’t a new thing – all the hybrid solutions do it and there are other vendor solutions that were designed for tiering – but Oracle built the FS1 Flash Storage System from the fast “flash” tier down, not by adding flash to a slower or existing HDD-based architecture working “upwards.” This required designing intelligent automated management to take advantage of flash for performance while leveraging HDD to balance out cost. This new architecture has internal communication links dedicated to flash media with separate IO paths for HDDs, unlike traditional hybrids that might rely solely on their older, standard HDD-era architectures that can internally constrain high-performance flash access.

Oracle FS1 is a highly engineered SAN storage system with key capabilities that set it apart from other all-flash storage systems, including built in QoS management that incorporates business priorities, best-practices provisioning, and a storage alignment capability that is application aware – for Oracle Database naturally, but that can also address a growing body of other key enterprise applications (such as Oracle JD Edwards, PeopleSoft, Siebel, MS Exchange/SQL Server, and SAP) – and a “service provider” capability to carve out multi-tenant virtual storage “domains” while online that are actually enforced at the hardware partitioning level for top data security isolation.

In this report, we’ll dive in and examine some of the great new capabilities of the Oracle FS1. We’ll look at what really sets it apart from the competition in terms of its QoS, auto-tiering, co-engineering with Oracle Database and applications, delivered performance, capacity scaling and optimization, enterprise availability, and OPEX reducing features, all at a competitive price point that will challenge the rest of the increasingly flash-centric market.

It's time to shift from data-dumb to data-aware storage

With flash and virtualization technologies becoming readily available, the time has come for storage to evolve from data dumb to data aware.

Qumulo Core: Data-Aware Scale-Out NAS Software (Product Profile)

Let's face it: Today’s storage is dumb. Mostly it is a dumping ground for data. As we produce more data we simply buy more storage and fill it up. We don't know who is using what storage at a given point in time, which applications are hogging storage or have gone rogue, what and how much sensitive information is stored, moved or accessed by whom, and so on. Basically, we are blind to whatever is happening inside that storage array. On the other hand, storage should just work, users of storage should see it as an endless invisible resource, while the administrators of storage should be able to unlock the value of data itself through real-time analytical insight, not fighting fires just to keep storage running and provisioned.

Storage systems these days are often quoted in petabytes and will eventually move to exabytes and beyond. Businesses are being crushed under the weight of this data sprawl and a new tsunami of data is coming their way as the Internet of Things fully comes online in the next decade. How are administrators dealing with this ever increasing appetite to store more data? It is time for a radical new approach to building a storage system, one that is aware of the information stored within while dramatically reducing the time administrators spend managing the system.

Welcome to the new era of data aware storage. This could not have come at a better time. Storage growth, as we all know, is out of control. Granted the cost per GB keeps falling at about a 40% per year rate, but we keep growing capacity at about a 60% growth rate. This causes both the cost and capacity to keep increasing every year. While cost increase is certainly an issue, the bigger issue is manageability. And not knowing what we have buried in those mounds of data is a bigger issue. Instead of data being an asset, it is a dead weight that keeps getting heavier. If we didn’t do something about it, we would simply be overwhelmed, if we are not already.

The question we ask is why is it possible to develop data aware storage today when we couldn’t yesterday? The answer is simple: flash technology, virtualization, and the availability of “free” CPU cycles make it possible for us to build storage today that can do a lot of heavy lifting from the inside. While this was possible yesterday, if implemented, it would have slowed down the performance of primary storage to a point where it would be useless. So, in the past, we simply let it store data. But today, we can build in a lot of intelligence without impacting performance or quality of service. We call this new type of storage Data Aware Storage.

When implemented correctly, data aware storage can provide insights that were not possible yesterday. It would reduce risk for non-compliance. It would improve governance. It would automate many of the storage management processes that are manual today. It would provide insights into how well the storage is being utilized. It would identify if a dangerous situation was about to occur, either for compliance or capacity or performance or SLA. You get the point. Storage that is inherently smart and knows: what type of data it has, how it is growing, who is using it, who is abusing it, and so on.

In this profile, we dive deep into a new technology, called Qumulo Core, the industry’s first data-aware scale-out NAS platform. Qumulo Core promises to radically change the scale-out NAS product category by using built-in data awareness to massively scale a distributed file system, while at the same time radically reducing the time to administer a system than can hold billions of files. File systems in the past could not scale to this level because administrative tools would crush under the weight of the system.
