Storage infrastructure management is still elusive

We've been on a multi-decade crusade to address performance and basic storage management tasks to handle things such as protecting data in place, and scaling and expanding our data storage systems to meet new requirements. But today, when performance and scaling and expansion issues are addressed, it will be revealed that the last major challenge in the data center is storage management.

Software Storage Solutions for Virtualization

Storage has long been a major source of operational and architectural challenges for IT practitioners, but today these challenges are most felt in the virtual infrastructure. The challenges are sprung from the physicality of storage – while the virtual infrastructure has made IT entirely more agile and adaptable than ever before, storage still depends upon digital bits that are permanently stored on a physical device somewhere within the data center.

For practitioners who have experienced the pain caused by this – configuration hurdles, painful data migrations, and even disasters – the idea of software-defined storage likely sounds somewhat ludicrous. But the term also holds tremendous potential to change the way IT is done by tackling this one last vestige of the traditional, inflexible IT infrastructure.

The reality is that software-defined storage isn’t that far away. In the virtual infrastructure, a number of vendors have long offered Virtual Storage Appliances (VSAs) that can make storage remarkably close to software-defined. These solutions allow administrators to easily and rapidly deploy storage controllers within the virtual infrastructure, and equip either networked storage pools or the direct-attached storage within a server with enterprise-class storage features that are consistent and easily managed by the virtual administrator, irrespective of where the virtual infrastructure is (in the cloud, or on premise). Such solutions can make comprehensive storage functionality available in places where it could never be had before, allow for higher utilization of stranded pools of storage (such as local disk in the server), and enable a homogeneous management approach even across many distributed locations.

The 2012-2013 calendar years have brought an increasing amount of attention and energy in the VSA marketplace. While the longest established, major vendor VSA solution in the marketplace has been HP’s StoreVirtual VSA, in 2013 an equally major vendor – VMware – introduced a similar, software-based, scale-out storage solution for the virtual infrastructure – VSAN. While VMware’s VSAN does not directly carry a VSA moniker, and in fact stands separate from VMware’s own vSphere Storage Appliance, VSAN has an architecture very similar to the latest generation of HP’s own StoreVirtual VSA. Both of these products are scale-out storage software solutions that are deployed in the virtual infrastructure and contain solid-state caching/tiering capabilities that enhance performance and make them enterprise-ready for production workloads. VMware’s 2013 announcement finally meant HP is no longer the sole major vendor (Fortune 500) with a primary storage VSA approach. This only adds validation to other vendors who have long offered VSA-based solutions, vendors like FalconStor, Nexenta, and StorMagic.

We’ve turned to a high level assessment of five market leaders who are today offering VSA or software storage in the virtual infrastructure. We’ve assessed these solutions here with an eye toward how they fit as primary storage for the virtual infrastructure. In this landscape, we’ve profiled the key characteristics and capabilities critical to storage systems fulfilling this role. At the end of our assessment, clearly each solution has a place in the market, but not all VSA solutions are ready for primary storage. Those that are, may stand to reinvent the practice of storage in customer data centers.

Backup Balancing Act: Growing Pains with Data Backup and the Cost of Migration

Backup these days is, as I view it, an incredibly interesting topic. Data protection has always been a challenging operation for the business. When you think about it, it is one of the most physical of systems, requiring tremendous amounts of data movement and storage - moving and storing the same bits over and over again with such requirements for speed and then storage that the task has at many different times in the history of IT seemed like mission impossible.

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.

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.

Redefining Storage Operations with VMware Virtual SAN

Virtual Machines much like physical ones require storage. Storage, on all its forms, is exponentially growing in recent years – almost doubling every other year. With the explosion of storage demands, IT managers are challenged to deliver the same service levels to virtual environments as they do with physical ones.

Software-defined Storage and VMware's Virtual SAN Redefining Storage Operations

The massive trend to virtualize servers has brought great benefits to IT data centers everywhere, but other domains of IT infrastructure have been challenged to likewise evolve. In particular, enterprise storage has remained expensively tied to a traditional hardware infrastructure based on antiquated logical constructs that are not well aligned with virtual workloads – ultimately impairing both IT efficiency and organizational agility.

Software-Defined Storage provides a new approach to making better use of storage resources in the virtual environment. Some software-defined solutions are even enabling storage provisioning and management on an object, database or per-VM level instead of struggling with block storage LUN’s or file volumes. In particular, VM-centricity, especially when combined with an automatic policy-based approach to management, enables virtual admins to deal with storage in the same mindset and in the same flow as other virtual admin tasks.

In this paper, we will look at VMware’s Virtual SAN product and its impact on operations. Virtual SAN brings both virtualized storage infrastructure and VM-centric storage together into one solution that significantly reduces cost compared to a traditional SAN. While this kind of software-defined storage alters the acquisition cost of storage in several big ways (avoiding proprietary storage hardware, dedicated storage adapters and fabrics, et.al.) here at Taneja Group what we find more significant is the opportunity for solutions like VMware’s Virtual SAN to fundamentally alter the on-going operational (or OPEX) costs of storage.

In this report, we will look at how Software-Defined Storage stands to transform the long term OPEX for storage by examining VMware’s Virtual SAN product. We’ll do this by examining a representative handful of key operational tasks associated with enterprise storage and the virtual infrastructure in our validation lab. We’ll examine the key data points recorded from our comparative hands-on examination, estimating the overall time and effort required for common OPEX tasks on both VMware Virtual SAN and traditional enterprise storage.

For Lowest Cost and Greatest Agility, Choose Software-Defined Data Center Architectures

The era of the software-defined data center is upon us. The promise of a software-defined strategy is a virtualized data center created from compute, network and storage building blocks. A Software-Defined Data Center (SDDC) moves the provisioning, management, and other advanced features into the software layer so that the entire system delivers improved agility and greater cost savings. This tectonic shift in the data center is as great as the shift to virtualized servers during the last decade and may prove to be greater in the long run.

This approach to IT infrastructure started over a decade ago when compute virtualization - through use of hypervisors - turned compute and server platforms into software objects. This same approach to virtualizing resources is now gaining acceptance in networking and storage architectures. When combined with overarching automation software, a business can now virtualize and manage an entire data center. The abstraction, pooling and running of compute, storage and networking functions, virtually, on shared hardware brings unprecedented agility and flexibility to the data center while driving costs down.

In this paper, Taneja Group takes an in-depth look at the capital expenditure (CapEx) savings that can be achieved by creating a state-of-the-art SDDC, based on currently available technology. We performed a comparative cost study of two different environments: one using the latest software solutions from VMware running on industry standard and white label hardware components; and the other running a more typical VMware virtualization environment, on mostly traditional, feature rich, hardware components, which we will describe as the Hardware-Dependent Data Center (HDDC). The CapEx saving we calculated were based on creating brand new (Greenfield) data centers for each scenario (an additional comparison for upgrading an existing data center is included at the end of this white paper).

Our analysis indicates that a dramatic cost savings, up to 49%, can be realized when using today’s SDDC capabilities combined with low cost white-label hardware, compared to a best in class HDDC. In addition, just by adopting VMware Virtual SAN and NSX in their current virtualized environment users can lower CapEx by 32%. By investing in SDDC technology, businesses can be assured their data center solution can be more easily upgraded and enhanced over the life of the hardware, providing considerable investment protection. Rapidly improving SDDC software capabilities, combined with declining hardware prices, promise to reduce total costs even further as complex embedded hardware features are moved into a more agile and flexible software environment.

Depending on customers’ needs and the choice of deployment model, an SDDC architecture offers a full spectrum of savings. VMware Virtual SAN is software-defined storage that pools inexpensive hard drives and common solid state drives installed in the virtualization hosts to lower capital expenses and simplify the overall storage architecture. VMware NSX aims to make these same advances for network virtualization by moving security and network functions to a software layer that can run on top of any physical network equipment. An SDDC approach is to “virtualize everything” along with data center automation that enables a private cloud with connectors to the public cloud if needed.

HP StoreVirtual VSA and VMware Virtual SAN - A Closer Look

The age of the software defined datacenter (SDDC) and converged infrastructure is upon us. The benefits of abstracting, pooling and running compute, storage and networking functions together on shared commodity hardware brings unprecedented agility and flexibility to the datacenter while driving actual costs down. The tectonic shift in the datacenter caused by software-defined storage and networking will prove to be as great as, and may prove to be greater than, the shift to virtualized servers during the last decade. While software-defined networking (SDN) is still in its infancy, software-defined storage (SDS) has been developing for quite some time.

LeftHand Networks (now HP StoreVirtual) released its first iSCSI VSA (virtual storage appliance) in 2007, which brought the advantages of software-based storage to small and midsize company environments. LeftHand Networks’ VSA was a virtual machine that hosted a software implementation of LeftHand’s well-regarded iSCSI hardware storage array. Since that time many other vendors have released VSAs, but none have captured the market share of HP’s StoreVirtual VSA. But the release of VMware Virtual SAN (VSAN) in March of 2014 could change that as VSAN, with the backing of the virtualization giant, is poised to be a serious contender in the SDS marketplace. Taneja Group thought that it would be interesting to take a closer look at how a mature, well regarded and widely deployed SDS product such as HP StoreVirtual VSA compares to the newest entry in the SDS market: VMware’s VSAN.

The observations we have made for both products are based on hands-on lab testing, but we do not consider this a Technology Validation exercise because we were not able to conduct an apples-to-apples comparison between the offerings, primarily due to the limited hardware compatibility list (HCL) for VMware VSAN. However, the hands-on testing that we were able to conduct gave us a very good understanding of both products. Both products surprised and, more often than not, did not disappoint us. In an ideal world without budgetary constraints, both products may have a place in your datacenter, but they are not by any means interchangeable. We found that one of the products would be more useful for a variety of datacenter storage needs, including some tier 1 use cases, while the other is more suited today to supporting the needs some of tier 2 and tier 3 applications.
