The Remote Office Data Storage Quandary: Is Cloud the Answer?

Wednesday, December 14th, 2011

If you ask IT administrators about their goals for storage infrastructure at remote and/or branch office (ROBO) locations, you’ll likely hear that they want to improve application performance and, at the same time, minimize the footprint of remote office storage infrastructure.  However, maximizing performance and minimizing footprint are competing priorities and optimizing both can be a challenge.

Having a goal to remove or minimize remote office storage infrastructure makes a lot of sense. Given most remote locations no longer have dedicated IT staffing onsite, an increased and significant burden can be avoided for the administrators working at main locations.

Improving overall application performance at remote offices also makes a lot of sense to maximize productivity of remote workers. The good news?  There currently exists in the marketplace a category of devices that provides local speed data storage access with a very small footprint: cloud storage gateways. Even better, CloudArray, an enterprise storage gateway from TwinStrata, enables local speed iSCSI access to a broad choice of public cloud storage providers, private cloud storage providers and/or existing storage, representing one of the the industry’s most flexible storage solutions.

A recent 2011 ESG survey of remote office and branch office environments revealed that a third of remote offices with over 25 employees had an average of 25TB of data at each remote office, a considerable amount of storage to maintain and manage. Taking a closer look, the following pie chart breaks down remote office storage infrastructure by type:

According to the survey results, 56% of storage deployed at ROBOs consists of SAN or NAS storage, reflecting the priority for local speed data access at those locations. The tradeoff is that managing enterprise storage infrastructure at those locations can lead to a number of headaches around

  • Hardware life cycles and upgrades
  • Running out of and replenishing capacity
  • Providing backup, replication or disaster recovery for the data stored at each site

Enterprise storage gateways are a great way to consolidate remote site storage footprint to software-only installations or small form-factor appliances while, at the same time, maintaining the plug-compatibility, speed and capacity of local storage infrastructure. Moreover, consolidation allows administrators to centralize data storage at a primary data center or in the cloud with the following advantages

  • A local iSCSI interface at each site without the iSCSI storage array footprint
  • Data reduction (compression and deduplication) before data is sent to the primary site or cloud, increasing usable centralized capacity
  • Ability to re-allocate capacity simply and dynamically between remote sites without moving hardware
  • Ability to maintain a cache or a full local copy that is replicated to the primary site or cloud for a multi-site disaster recovery strategy

Finally, a software enterprise storage gateway can be deployed virtually anywhere in the world in minutes, without additional hardware, allowing IT to rapidly meet ever-changing business needs.

If you are concerned about making the tradeoff between infrastructure footprint and performance for ROBO environments, it may be time to consider the benefits of an enterprise storage gateway solution.

Is it Time to Look Beyond the Cloud?

Thursday, December 1st, 2011

For many businesses that haven’t yet formulated their cloud adoption plans, the notion of looking beyond the cloud may sound a bit peculiar. After all, isn’t cloud the final frontier that promises to transform traditional IT infrastructure into a control panel offering limitless resources on-demand? That is certainly the outcome that many businesses aspire to. The truth is, regardless of the outcome, much can be gleaned from examining how cloud infrastructure influences business IT efficiencies.

Let’s take a look at public cloud storage and how it has inspired new ways of thinking when it comes to storage infrastructure management. For some, it may be difficult to look beyond the logistics of public cloud storage which often dictate moving data into a distant data center and relinquishing a certain amount of control. However, the benefits of adopting the cloud bring IT efficiencies that could not be otherwise realized, eliminating one of the more burdensome aspects of data storage management.

What burdensome aspect is that? Specifically, the sprawl of storage infrastructure

  • In the primary data center – Storage arrays have a recurring life cycle that demands upgrading and replacing equipment on a regular basis as capacity needs increase.  The process is costly, disruptive, risky and causes overlap of equipment costs, underutilization and overpayment for unused capacity. Read all about the storage array lifecycle here and learn how a large school system changed that pattern once and for all.
  • In the remote office or branch office – While recent surveys such as ESG’s Remote Office/Branch Office Technology Trends show that a large number of businesses would prefer to centralize their data storage, the numbers reveal that most still have data storage at remote sites, primarily consisting of SAN or NAS devices. This not only perpetuates the management lifecycle described above, but does so for unmanned sites with no dedicated administrative staff, clearly an IT management nightmare.
  • For disaster recovery – Replicated storage infrastructure for disaster recovery costs as much to purchase, run and maintain as primary storage infrastructure and has the same life cycle issues described above, not to mention redundant and costly facilities.
  • For peaks and valleys in demand – Here, storage infrastructure remains primarily idle and unused except when capacity needs increase for certain projects, testing, development or analytics that may occur seasonally

The solution for this sprawl does not necessarily involve moving all storage infrastructure to the cloud. For many businesses, that is simply not a practical, realistic or fathomable near-term solution. However, the consolidation of storage infrastructure is clearly a viable strategy.

A reasonable approach might be to leave the main data center as is but start to address data storage sprawl that is occurring in remote locations. What if you could reduce the remote and branch office storage footprint to a single piece of software per site?  What if you could substantially reduce the storage capacity required for disaster recovery while at the same time pooling storage resources to address peaks and valleys in demand? Sprawl would diminish, utilization would improve and administrative burden would lessen.

The cloud can indeed be a means to this end. However, there are other options to consider. For instance, you could use CloudArray as your storage gateway and have a choice of consolidating the sprawl to a public cloud, private cloud, existing storage infrastructure or a combination of all three. Bottom line?  You can reduce sprawl without having to rely on any particular type of cloud, realize significant cost and administrative savings, and replace your ever expanding storage footprint with software, thereby eliminating a complex life cycle.

Keep in mind there is nothing magical about the storage infrastructure that backs cloud storage. Rather, cloud storage is all about the methodologies that squeeze the utmost efficiency out of commoditized storage components, culminating from years of experience on the part of cloud providers.  For this reason, businesses need to look beyond adopting cloud — and instead, look to adopt cloud methodologies that can bring them substantial IT efficiencies.

Cloud SANs: What the Data Storage Vendors Forgot

Tuesday, November 15th, 2011

Storage area networks (SANs) have become the ubiquitous deployment model for block data storage systems, interconnecting formerly siloed storage arrays with a common high-speed network running standardized protocols such as Fibre Channel or iSCSI. It was over a decade ago that the ability to connect multi-vendor storage arrays into a common network proved revolutionary and changed the way storage arrays were configured and consumed by businesses. However, with continuing advancements in cloud storage solutions, IT administrators are now rethinking the traditional SAN.

As with many mature technologies, SANs have forced IT administrators to accept a number of limitations. The most notable are

  • The traditional 3-5 year lifecycle of storage arrays, resulting in costly upgrades, frequent migrations and the introduction of considerable business risk
  • The inability to scale performance across geographical distances without storage arrays at each site
  • The inability to easily allocate and re-allocate storage capacity across sites
  • Replication and disaster recovery that require double the number of storage arrays and infrastructure

A combined cloud storage and enterprise cloud storage gateway solution, such as CloudArray, easily overcomes all of these limitations. Pay-as-you-go cloud storage breaks the traditional storage lifecycle offering an unlimited tier of data storage without a need for hardware upgrades, while enterprise storage gateway technology enables secure local-speed performance and iSCSI access from virtually any geographic location with the ability to dynamically allocate/reallocate storage across sites as needed.

TwinStrata’s recent launch of CloudArray 3.0 extends these cloud benefits beyond just public and private clouds — to existing data storage. With CloudArray 3.0, it is easier than ever to build a Cloud SAN that transcends the limitations of existing SANs. Companies can enjoy the attributes of cloud storage immediately using their existing storage as the starting point and, when ready, seamlessly expand their existing storage pool with public and/or private cloud storage.

CloudArray Cloud SAN

Cloud SANs eclipse the limitations of traditional SANs by offering high-performance, optimized data access from virtually anywhere, with a very small local footprint. This makes them ideal for remote offices or other distributed environments. Cloud SANs also offer centralized capacity management and centralized disaster recovery for flexible and robust multi-site deployments.

Key benefits of Cloud SANs include

  • Ability to work with public clouds, private clouds and/or existing storage using software or hardware caching appliances, each with access to virtually unlimited capacity
  • Ability to scale local speed performance across sites without distance limitations
  • Ability to allocate/reallocate storage capacity between sites dynamically, simplifying movement of capacity resources to locations that need them most
  • Built-in consolidated replication and disaster recovery for each caching appliance

As ground-breaking as SANs were when they launched over a decade ago, Cloud SANs represent the next revolutionary step in simplifying deployment of data storage for businesses. Whereas traditional SANs are limited in terms of multi-site scale, capacity utilization and cost, Cloud SANs offer robust, cost-effective solutions that scale geographically and optimize data storage utilization.

Dispelling 5 Myths About Cloud Storage

Sunday, October 16th, 2011

Atlas

If you are considering cloud storage for storing business data, you may have questions regarding control and security. The truth is that not all cloud storage solutions are created equal, but when you choose an enterprise-class gateway solution to enable on-premise access to cloud storage, you not only stay in control of your data — you benefit from a level of security that rivals local storage.

With today’s cloud storage solutions ranging from consumer-grade to enterprise-class, offering huge variations in security, availability and performance, it’s really no wonder why confusion persists. In the interest of clearing the confusion, I think it’s time to debunk a number of common myths and misconceptions about cloud storage deployments for businesses. To do that, I’ve listed 5 familiar objections and myths about cloud storage that are addressed by enterprise-class cloud storage gateways:

Myth #1: It’s not secure enough

Data in the cloud can’t be safe, can it?

With cloud storage gateways offering the option of at-rest AES data encryption with locally managed keys along with fully encrypted data transfers, your data may be safer stored in the cloud rather than stored locally without encryption. Additionally, by storing encryption keys locally and separately from the cloud provider, you can even protect against an attempted breach on the cloud provider side (by let’s say a rogue employee) without exposure of data.

But what if your organization’s compliance requirements prevent you from storing any data outside your firewall? In that case, there are a number of private cloud offerings that can be deployed on-premise – EMC, Mezeo, Nirvanix, Scality and OpenStack to name a few. Even if your data must stay within your firewall, there is no reason to overlook the benefits of cloud storage.

Myth #2: It’s too complicated

I need to invest time learning new cloud storage APIs and porting applications.

With a cloud storage gateway solution, particularly one that is software-based, you can access storage capacity that will accommodate multiple Petabytes of data within minutes. There are no APIs to learn and no required changes to existing applications.

Think about that.  Traditionally, if you want to bring multiple Petabytes of storage capacity into your existing environment, you arrange a “fork-lift” of racks of storage equipment. Not only is that complicated, but what’s worse is that that infrastructure will only typically last 3-5 years. Soon, you’ll be right back into the next storage hardware upgrade cycle.

Myth #3: My data will be locked into the cloud

At least if I wait, I won’t run the risk of locking into the wrong cloud provider.

With dozens of cloud storage providers ranging from public to private to open-source clouds available today, cloud storage gateways offer you the flexibility to choose the provider that’s right for you.  In fact, you can even choose multiple providers simultaneously or switch from one to another. With open access to a growing ecosystem of providers, there is no reason to wait.

Be sure to invest in a gateway that is not locked into a single provider and is not single purpose. Instead, look for a gateway that can store backups, archives or even copies of primary data across a broad choice of providers simultaneously.

Myth #4: Why add risk? Maintaining the status quo is the safest bet

The folks who designed our existing storage environment didn’t need the cloud. Why do we?

Often, the status quo is a compromise that doesn’t include a robust disaster recovery solution, placing your entire business at risk. Perhaps the status quo involves shipping unencrypted tapes offsite as a first line of disaster recovery.  Think about the last time you ran a disaster drill and ask yourself – how quickly can I get my business back up and running? With enterprise-class cloud storage gateways, it’s simple to store data offsite for disaster recovery, with instant access from virtually anywhere.

You may consider local storage infrastructure relatively risk-free. However, the continuous purchase and retirement of on-premise storage arrays creates business risk on a regular basis, introducing complex and costly migration operations into the business. Maintenance windows, long migrations, and even policy changes can be particularly disruptive.

Myth #5: What if I work myself out of a job?

No one ever lost their job sticking with local storage infrastructure.

This particular argument has a knack for resurfacing with all new technologies. While cloud compute and storage have become very powerful tools for augmenting existing IT infrastructure, they still require skillful deployments that follow IT best practices.  The benefit of offloading the infrastructure to the provider is that it significantly reduces some of the more cumbersome IT tasks around infrastructure management. However, the task of architecting and deploying a supportable solution still remains.

Consider instead the consequences of inaction. Ignoring cloud infrastructure options available today may put your business at risk of being overtaken by more nimble competitors who are, in fact, leveraging the cloud, streamlining their operations, and improving their productivity. You may indeed work yourself out of a job in a way you may not have quite envisioned.

Bottom line? Enterprise-class cloud storage gateways have come a long way and address the risks of cloud storage deployments, making integration seamless and enabling huge cost and administrative savings. If you haven’t kept abreast of recent advances, you may want to set some time aside to revisit how enterprise-class gateways, like CloudArray, are making it amazingly easy to start augmenting your IT infrastructure.

Is there a need for a cloud storage broker?

Thursday, September 8th, 2011

clouds for sale

A recent topic of discussion in cloud computing has been the notion of the cloud broker as an emerging business in the evolving cloud ecosystem, a “middleman” of sorts in the same sense as a real estate broker or a mortgage broker. A Gigaom article by Stacey Higginbotham entitled “Future of cloud computing … more clouds. Seriously” cites a Forrester report on the topic and delves into what such such a service might look like. The article suggests capabilities that include Cloudbursting, or instantly moving applications and data from one cloud to another, and in an interesting twist, it even suggests brokering human IT resources on a seasonal basis.

The concept sounds novel, albeit even futuristic, but I’d like to examine it from the point of view of cloud storage since business adoption is growing and many of the principles apply. An automated infrastructure that decides where data gets stored based on a set of policies and attributes ought to be appealing. In fact, the idea is not really new. It sounds quite similar to automated storage tiering (see Rick Vanover article), or auto-tiering, which enables the movement of data across local storage tiers or subsystems. The main difference is incorporating the choice of private cloud storage providers as well as a number of public cloud storage providers.

Since auto-tiering is available today, you may be wondering if there is an easy way to incorporate cloud storage. It turns out there is. A cloud storage gateway or appliance, like TwinStrata CloudArray, allows multiple cloud storage tiers from one or many providers to seamlessly integrate with existing auto-tiering products. It also offers a way to test drive and benchmark storage from a number of cloud providers first hand. This would be in addition to researching cloud providers on paper, on the basis of attributes such as price, performance, service level agreements (SLA), certifications, etc.

With auto-tiering able to make real-time decisions on data placement across both traditional and cloud storage, where does that leave the future of the cloud storage broker? Well, perhaps the cloud storage broker will do a better job of accounting for fluctuations in market price and even find favorable pricing based on peaks and valleys in supply and demand. Another value might be tracking provider SLA compliance over time, which may be more informative for prospective customers than just the text of the SLA itself. Perhaps there are other real-time attributes specific to the individual cloud providers that a broker can track — and lest I forget, there is also the potential for managing seasonal needs for people resources.

Do you see potential value in a cloud storage broker? Let us know.

Future of cloud computing … more clouds. Seriously.

Cloud Storage for Multi-site Consolidation, Part III: Compute Anywhere

Tuesday, July 19th, 2011

Part I of this series covered the benefits of Multi-site Storage Consolidation using the cloud, while Part II focused specifically on disaster recovery benefits. This installment explores the ability to access your data virtually anywhere, one of the unique benefits enabled by cloud storage.

Let’s say you run a database on server and storage hardware at your main datacenter and you want to run analytics on that data to better understand your business trends. Let’s also say the results of those analytics were only needed once or twice a month and you felt purchasing additional dedicated hardware was a bit wasteful. How would you proceed with the deployment?

A secondary site with excess compute capacity might be an ideal solution if you could get a copy of your database there. If you are running a cloud storage hybrid appliance like CloudArray, you’re in luck. You can move ownership of a data volume or a snapshot of a data volume between sites, across CloudArray instances. You now have access to your data or a copy of your data wherever and whenever you need it.

But what if  you don’t have the luxury of excess compute capacity at a secondary site or any site for that matter? What if growing server infrastructure is just not an option? That’s where CloudArray shines. You can simply bring up another instance of CloudArray in the cloud and run analytics using pay-as-you-go cloud compute, paying only for the compute cycles you use, with no need to purchase additional hardware. Sound intriguing?

Keep in mind that not every cloud storage solution supports the capability to access your data for compute tasks anywhere. Some gateways make cloud storage look like a local storage array, with only a single local point of access. Other appliances appear as storage arrays, with an extra tier of storage in the cloud that is only accessed internally. Unlike solutions that limit access to your data, CloudArray let’s you enjoy all of the benefits of cloud storage, with local-speed performance, seamless interoperability and a multi-site distributed storage model.
