The #1 pain point in the data center is poor performance. That’s what we found from our study of 1,000 data center professionals, who every day watch virtual machines (VM) conflict with databases, slow each other down, and eat up hours spent fine-tuning storage and tackling trouble tickets.
A huge contributor to this performance pain is what’s called “the noisy neighbor problem” — a VM consuming too many resources at the expense of others.
The problem stems from LUNs, the conventional storage groups made up of dozens or even hundreds of VMs. When one of them gets noisy, demanding more than its share of performance reserves, it slows down its neighbors and throws the entire LUN into chaos.
Because they’re built on that LUN architecture, most storage environments running VMs face this challenge. Stopping these rogue VMs is difficult because they’re nearly invisible to scrutiny and correction.
Here’s how you put the issue to rest and guarantee every VM’s performance: isolation. By eliminating the LUN and giving every VM its own neighborhood through VM-aware storage, you can more precisely control the resources apps can demand. Continue Reading…
When faced with bad choices, it’s sometimes easier to just do nothing, even if that inaction can lead to a new round of issues.
Such was the situation for a children’s hospital in one U.S. city. The hospital had no disaster recovery (DR), and it was stuck with an impractical plan from a consultant – backup hardware in a building across the street. Continue Reading…
You’ve never seen virtualization work like this before.
vSphere 6, the newest installment of VMware’s cloud computing OS, is available now for upgrade. The latest version has hundreds of new features and capabilities, but its true power lies in its breadth: vSphere 6 can “vMotion” instances across virtual switches, vCenters, and long distances. Now an instance can be moved from any cluster of computers and servers in an organization to another, regardless of where the two clusters are, and regardless of the version of vCenter that the second destination cluster is running.
But as useful as this load-bearing capability can be for spreading virtual machines throughout a network to maintain uptime, it can also create issues with your Microsoft licensing. Before you upgrade to vSphere 6, make sure you know the potential conflicts and take steps to remedy them. Continue Reading…
Gartner identified 10 strategic technology trends for 2014 at a symposium last fall, including mobile, the Internet of Everything, and cloud technology. As we enter 2014, several megatrends stand out from the rest, shaping the way we do business and accelerating the transformation of IT. It’s important to understand these trends beyond the buzzwords and marketing lingo. The key to preparing for tech’s imminent shift is recognizing the business drivers behind these changes and acknowledging their impact on the future of business.
Here are the megatrends that should be top of mind for IT departments and business owners alike:
Software-defined anything (SDx)
The traditional datacenter landscape has changed forever, leaving infrastructure abstracted and virtualized, delivered as a service. We’re seeing virtualization extend well beyond just computing, with storage and network virtualization quickly becoming the norm for most organizations.
This model holds true regardless of whether the infrastructure resides internally or in the cloud. Dependency on physical hardware is being eliminated as software manages everything, increasing flexibility and agility. As infrastructure becomes highly virtualized and moves toward the private cloud, traditional IT resources need to evolve or risk becoming irrelevant.
As businesses begin to consume infrastructure as a service, the skills required to architect and support these environments must evolve as well. Once infrastructure is fully abstracted and optimized, organizations can shift their focus to developing applications to support business outcomes. Continue Reading…
I’m fresh off the 10th annual VMworld, and amid the sea of often conflicting visions for the future IT landscape, one constant remains: Organizations are making IT architecture decisions today that will provide the foundation for future success or failure.
SHI has made significant investments in building resources and processes to help our customers make sense of these different visions. To help wade through the sea of change, here is a summary of the major themes and announcements from last week’s VMworld, along with how SHI can provide additional customer insight and support:
1. vCloud Hybrid Service (vCHS) becomes generally available to U.S. customers in September.
Back in May, VMware announced vCHS, an Infrastructure-as-a-Service (IaaS) offering built on VMware vSphere that enables customers to extend the same skills, tools, networking, and security models across both on-premises and off-premises environments. The Early Access Program’s momentum signals the potential demand for vCHS when it becomes generally available this month.
What this means for SHI customers: As one of VMware’s top partners, SHI has substantial experience helping customers transform their business based on VMware’s virtualization platform, of which vCHS is a natural extension. SHI was also one of VMware’s initial vCHS launch partners, so we’ve had a few months’ head start on other technology resellers. In that time, we’ve built resources and processes to support our customers’ adoption of vCHS and help them maximize their IT investment. Continue Reading…
Software-defined data center (SDDC) is the latest buzzword in our industry. SDDC is the phrase used to refer to a data center in which all infrastructure is virtualized and delivered as a service. Management of the data center is automated by software — meaning the configuration of hardware is done through upper-level software systems. This allows new services to be turned on or off rapidly and existing services to grow and shrink as needed.
This is very different from traditional data centers in which the infrastructure is typically defined by hardware and devices that might require multiple IT administrators to configure them, which can greatly extend the time to market for these solutions.
There are three core components of the software-defined data center: network virtualization, server virtualization, and storage virtualization. There is also an overlying layer that has to support the business logic of SLAs and application performance demands of the organization.
The software-defined data center is considered by many to be the next step in the evolution of virtualization and cloud computing. What separates the software-defined data center from the cloud is its ability to support legacy enterprise applications as well as new services written with cloud in mind. Continue Reading…
If you’ve been watching this space over the past few weeks, you know that my past two blog posts have been part of a series of posts dedicated to reflecting on the first year of the SHI Cloud.
When we launched our cloud offering last summer, we knew that interactions with our customers would validate the true differentiators in our service and help us identify areas for improvement. So far, I’ve covered how our unique networking design has helped us build a successful cloud model for our customers, how we learned that customers prefer simplicity in their cloud service, and how keeping track of every single detail of the cloud for the past year has paid off.
Today, I’m nearing the end of the series with the last two lessons that the past year has taught us: the business model conversation and the importance of transformative ease-of-use. Continue Reading…
In my last post, I talked about how networking from the bottom up helped us reach success when we built the SHI Cloud. In the second part of our “Lessons Learned” series, I want to stress the importance of simplicity and attention to detail.
Lesson #2: Keep it simple
Customers want the SHI Cloud to provide a secure networking model, world-class virtual infrastructure, and appropriate security controls, all backed by a well-designed operations team with a resilient data center of the highest quality. After that, they want us to get out of the way.
Unfortunately, not all cloud providers do this. Amazon, for instance, has developed their own constructs for cloud computing — their own naming conventions, models, and ways of creating configurations pre-packaged for customers. So application teams, development teams, QA teams, and other functional users of IT infrastructure would have to learn to do things differently if they went with the Amazon cloud.
Customers told us they wanted a cloud that fit with their current processes and operations. The SHI Cloud was built so that customers won’t have to change anything they’re already doing. They have virtual machines running applications or hosting development environments, and they do everything in very specific ways. They’ve invested a lot in their own design, and their own view of computing.
The benefits of virtualization are well known at this point. It’s not like it’s a new technology. It’s been an industry standard for the last five or six years, if not longer. However, we’re still seeing some mid-market customers that are hesitant to jump on the virtualization bandwagon. While many of these organizations don’t have a robust Fortune 50-type infrastructure, that doesn’t mean they can’t benefit from virtualization.
Those benefits are extensive. For example, the consolidation of an organization’s IT infrastructure, and anytime, anywhere access to its applications.
The main concern frequently expressed in our conversations with customers who are considering a switch to virtualization is in regards to business continuity. IT is being challenged more than ever to assure critical applications are always available to support lines of business.
