In the Cloud Era, The Era of Convergence Is Upon Us

The era of IT infrastructure convergence is upon us. Every major vendor has some type of offering under this category. Startups and smaller players are also "talking" convergence. But what exactly is convergence and why are all the vendors so interested in getting included in this category? We will explain below the history of convergence, what it is, what it is not, what benefits accrue from such systems, who the players are, and who is leading the pack in true convergence.

Violin Concerto 7000 All Flash Array: Performance Packed with Data Services

All Flash Arrays (AFAs) are plentiful in the market. At one level all AFAs deliver phenomenal performance compared to an HDD array. But comparing AFAs to an HDD-based system is like comparing a Ford Focus to a Lamborghini. The comparison has to be inter-AFAs and when one looks under the hood one finds the AFAs in the market vary in performance, resiliency, consistency of performance, density, scalability and almost every dimension one can think of.

An AFA has to be viewed as a business transformation technology. A well-designed AFA, applied to the right applications will not only speed up application performance but by doing so enable you to make fundamental changes to your business. It may enable you to offer new services to your customers. Or serve your current customers faster and better. Or improve internal procedures in a way that improves employee morale and productivity. To not view an AFA through the business lens would be missing the point.

In this Product Profile we describe all the major criteria that should be used to evaluate AFAs and then look at Violin’s new entry, Concerto 7000 All Flash Array to see how it fares against these measures.

Five VM-Level Infrastructure Adaptations

It used to be that IT struggled to intimately understand every app in order to provide the right supporting infrastructure. Today, server virtualization makes the job much easier, because IT can now just cater to VMs. By working and communicating at the VM level, both app owners and infrastructure admins stay focused, using a common API to help ensure apps are hosted effectively and IT runs efficiently.

Unified Storage Array Efficiency: HP 3PAR StoreServ 7400c versus EMC VNX 5600 (TVS)

The IT industry is in the middle of a massive transition toward simplification and efficiency around managing on-premise infrastructure at today’s enterprise data centers. In the past few years there has been a rampant onset of technology clearly focused at simplifying and radically changing the economics of traditional enterprise infrastructure. These technologies include Public/Private Clouds, Converged Infrastructure, and Integrated Systems to name a few. All of these technologies are geared to provide more efficiency of resources, take less time to administer, all at a reduced TCO. However, these technologies all rely on efficiency and simplicity of the underlying technologies of Compute, Network, and Storage. Often times the overall solution is only as good as the weakest link in the chain. The storage tier of the traditional infrastructure stack is often considered the most complex to manage.

This technology validation focuses on measuring the efficiency and management simplicity by comparing two industry leading mid-range external storage arrays configured in the use case of unified storage. Unified storage has been a popular approach to storage subsystems that consolidates both file access and block access within a single external array thus being able to share the same precious drive capacity resources across both protocols simultaneously. Businesses value the ability to send server workloads down a high performance low latency block protocol while still taking advantage of simplicity and ease of sharing file protocols to various clients. In the past businesses would have either setup a separate file server in front of their block array or buy completely separate NAS devices, thus possibly over buying storage resource and adding complexity. Unified storage takes care of this by providing ease of managing one storage device for all business workload needs. In this study we compared the attributes of storage efficiency and ease of managing and monitoring an EMC VNX unified array versus an HP 3PAR StoreServ unified array. The approach we used was to setup two arrays side-by-side and recorded the actual complexity of managing each array for file and block access, per the documents and guides provided for each product. We also went through the exercise of sizing various arrays via publicly available configuration guides to see what the expected storage density efficiency would be for some typically configured systems.

Our conclusion was nothing short of astonishment. In the case of the EMC VNX2 technology, the approach to unification more closely resembles a hardware packaging and management veneer approach than what would have been expected for a second generation unified storage system. HP 3PAR StoreServ on the other hand, in its second generation of unified storage has transitioned the file protocol services from external controllers to completely converged block and file services within the common array controllers. In addition, all the data path and control plumbing is completely internal as well with no need to wire loop back cables between controllers. HP has also made the investment to create a totally new management paradigm based on the HP OneView management architecture, which radically simplifies the administrative approach to managing infrastructure. After performing this technology validation we can state with confidence that HP 3PAR StoreServ 7400c is 2X easier to provision, 2X easier to monitor, and up to 2X more data density efficient than a similarly configured EMC VNX 5600.

EMC PowerPath: Optimized IO Multipathing for All Flash Arrays

All-flash arrays are changing the datacenter for the better. No longer do we worry about IOPS bottlenecks from the array: all-flash arrays (AFA) can deliver a staggering amount of IOPs. AFAs with the ability to deliver hundreds of thousands of IOPs are not uncommon. The problem now, however, is how to get the IOPS from the array to the servers. We recently had a chance to see how well an AFA using EMC PowerPath driver works to eliminate this bottleneck—and we were blown away. Most comparisons with datacenter infrastructure show a 10-30% improvement in performance; but, the performance improvement that we saw with PowerPath was extraordinary.

Getting bits from an array to server is easy —very easy, in fact. The trick is getting the bits from a server to an array in an efficient manner when you have many virtual machines (VM) on multiple physical hosts that are transmitting the bits over a physical network with a virtual fabric overlay; this is much more difficult. Errors can get introduced and must be dealt with, the most efficient path must be obtained and established, re-evaluated and reestablished continually, and any misconfiguration can produce less than optimal performance. In some cases, this can cause outages or even data loss. In order to deal with the “pathing,” or how the I/O travels from the VM to storage, the OS running on the host needs a driver, or in the case where multiple paths can be taken from the server to the array, a multipathing driver needs to be used to direct the traffic.

Windows, Linux, VMware and most other modern operating systems include a basic multipath driver; however, these drivers tend to be generic and not code optimized to extract the maximum performance from an array and come with only rudimentary traffic optimization and management functions. In some cases these generic drivers are fine, but in the majority of datacenters the infrastructure is overtaxed and its equipment needs to be used in the most efficient manner possible. Fortunately, storage companies such as EMC are committed to making their arrays work as performant as possible and spend a considerable amount of time and research to develop multipathing drivers optimized for their arrays. EMC invited us to take a look at how PowerPath, their optimized “intelligent” multipath driver, performed on an XtremIO flash array connected to a Dell PowerEdge R710 server running ESXi 6.0 while simulating an Oracle workload. We looked at the results of the various tests EMC ran comparing PowerPath/VE multipath driver against VMware’s ESXi Native Multipath driver and we were impressed—very impressed—by the difference that an optimized, multipath driver like PowerPath can make in a high IO traffic scenario.

Better Together: Optimizing VMware vSphere 6.0 Deployments with Dell EqualLogic PS Series

Although server virtualization provides enormous benefits for the modern data center, it can also be daunting from a storage perspective. Provisioning storage to match the exact virtual machine (VM) requirements has always been challenging, often ending in a series of compromises. Each VM will have its own unique performance and storage requirements; this can create over-provisioning and other inefficient uses of storage. A virtualization administrator has to try and match a VM’s storage requirements as close as possible to storage that has been pre-provisioned. Provisioning in this way is time consuming and does not possess the VM-level granularity required to meet the specific needs of the applications running in a VM. To exacerbate the problem, often, over the lifetime of a VM, the storage requirements for a VM will change, which requires ongoing diligence and review of the storage platform and manual intervention to meet the new requirements.

VMware vSphere 6.0 introduced the biggest change to the ESXi storage stack since the company’s inception with the inclusion of vSphere Virtual Volumes (VVol). VVol helps to solve the challenge of how to match a VM’s storage requirements with external storage capabilities on a per VM basis. We found that VVol when combined with Dell EqualLogic PS Series arrays become a powerful force in the datacenter.

In this brief, we call out some storage-related highlights of vSphere 6.0 such as Virtual Volumes, and then take a close look at how they, as well as traditional datastore stored VMs have been enhanced and packaged by Dell Storage into the EqualLogic PS Series storage solution. We will show how Dell and VMware have combined forces to deliver an enterprise-class virtual server and storage environment that is highly optimized and directly addresses the performance, availability, data protection and complexity challenges common in today’s business-critical virtualized data centers.
