In the vehicle manufacturing industry, companies want an efficient and economical way to ensure smooth operation of all servers, software and applications. Any instance of unscheduled downtime could lead to a loss of data, or in a worst case scenario, to a complete disruption of production and services.

Serve customer needs online without interruption

One European vehicle manufacturer, who understands the importance of protection against downtime, has been using Marathon solutions since 2000. As their security needs as an organization have grown, so has their relationship with Marathon. They began by using the Endurance 4000 system to help protect their forklift management system. Three years later, they upgraded to everRun FT to further safeguard files and applications and to ensure continuous server availability.

The implementation of everRun FT gave the company the opportunity to undertake other IT projects to maximize efficiency and reliability. They were able to establish a centralized network to allow the entire staff to access all applications and system updates remotely.

Defend 24/7 operations with Marathon everRun FT software

With these new initiatives in place, one company executive says that it is now more important than ever for applications and servers to be accessible 24/7 – no matter what. “A disruption to the provision of data and applications would affect every employee, and in the worst case scenario, halt operations altogether,” said the executive.

The company uses both Marathon’s everRun FT and SplitSite to allow two servers to operate simultaneously in 100 percent lock-step. SplitSite provides an additional layer of protection against larger scale failures and disasters. This means that the two servers create a single virtual environment and if one fails, no downtime will occur and all software, applications and data will continue to run on the remaining server.

The organization utilizes several levels of security, including a single server, a Windows cluster, and a Marathon System, but all of their most important and mission-critical applications are operated on everRun FT.

Elimination of system failure and increased competitive advantage

Any instance of unscheduled downtime would impact not only the company’s main factory, but also their several hundred other outlets. If an employee was unable to connect to the network because the server was down, all data on customers and products would become unavailable – this could mean a stall on productivity and unhappy customers. The company executive maintains that this is no longer a concern, thanks to Marathon. “With everRun FT, we no longer have to worry about downtime.”

We all like to think that we will be prepared in the event of an emergency, or a disaster. Hospitals exist if we fall sick; fire stations surround us if flames break loose; we are constantly preparing so if a catastrophe strikes, we are ready.

Preparing for a system’s disaster is no different. However, how to go about preparing for an event like this can be confusing. There are many options out there when it comes to protecting your system, each best suited for specific requirement. Unfortunately, many vendors use terms like disaster recovery and high availability interchangeably to describe their solutions when in fact they are usually designed for one or the other.

Disaster Recovery (DR) is the way to recover applications and from a system failure. DR is a reactive solution where if a failure occurs, IT relocates the data, builds the system over, and brings everything back up to working order. This takes time, a precious commodity that typically businesses relying on critical applications don’t have. In addition, recovering applications could bring about a number of side effects which you really don’t want to endure every time some minor failure happens.

But what if I could tell you that instead of worrying about how to recover from a computer system failing, you could simply prevent it from occurring at all?

Disaster tolerance (DT) is a proactive way to prevent system failure from impacting application and data availability. A disaster tolerant solution isn’t going to recover the data if there’s a disaster. Instead it will tolerate the fault if a disaster occurs – keeping an organization’s critical applications up and running at all times. It is not recovery, but rather prevention. And with solutions like our everRun SplitSite, separate servers don’t even need to be in the same building – they can be up to 100 miles apart with fault-tolerant protection between the two locations.

DR solutions are good for applications that can afford some downtime while you recover them. But for essential applications like Microsoft Exchange, SQL, and SharePoint, which need to be available all the time, disaster tolerance is often the best way to go.

So what combination of DT and DR protection would work best for your company’s applications?

Disaster tolerance (DT) is a proactive way to prevent system failure from impacting application and data availability. A disaster tolerant solution isn’t going to recover the data if there’s a disaster. Instead it will tolerate the fault if a disaster occurs – keeping an organization’s critical applications up and running at all times. It is not recovery, but rather prevention.

“When we describe everRun VM to customers and prospects, the common reaction is ‘it’s too good to be true’” – Steve Keilen, VP of Marketing for Marathon Technologies

It comes with everything you need to get started, including an evaluation copy of XenServer Enterprise Edition. Feel free to leave a comment or contact us with any questions you may have.

With Microsoft’s Hyper-V announcement a few weeks back, the buzz around virtualization continues to rise. In this Network World podcast, our CTO Jerry Melnick discusses what Microsoft’s announcement means for the virtualization industry. Jerry believes that Microsoft’s moves will bring virtualization within reach of many companies who have been hesitant about adopting it before now – giving Microsoft the opportunity to swim in uncharted waters where VMware hasn’t been able to go.

The podcast also highlights Jerry’s take on the thriving virtualization industry and how the growing virtualization ecosystem is creating solutions that “fill in the blanks” e.g. everRun VM allows customers of all sizes to “consolidate with confidence” with reliable availability for virtual servers.

Do you think availability is a critical factor for a successful virtualization deployment?

Following last week’s discussion, event attendees had additional questions that we didn’t get to answer even though we went ten minutes over. We wanted to continue the discussion here on our blog so we figured we would post the continuation of questions and answers for everyone to see. As we mentioned before, if you would like to view the presentation delivered last week by John Humphrey’s (IDC), Simon Crosby (Citrix) and Jerry Melnick (Marathon), download the presentation here.

Are there any performance limitations with everRun VM?

everRun VM supports any guest environment created by XenServer, including multi-CPU VM’s.

Effect of losing inter-server link?

As a best practice we recommend two Availability Links for redundancy. If one should be lost, we will continue to operate unaffected using the remaining one. If both are lost we will take action to prevent complete loss of the VM or SplitBrain.

How far apart can the two machines be – i.e. is there a propagation delay issue?

Host separation is a factor of network latency, which must be <10ms round trip. Current deployments have exceeded 100 miles.

In case of a disk failure, does everRun rebuild the disk from the good physical host to the bad one?

Correct. Recovery of storage is handled as a background task so as not to require downtime or otherwise impact the running VM and application.

When will level 3 of everRun VM be available?

Level-3, System-Level fault tolerance is scheduled for later this year.

What requirements are associated with the everRun Level 3 Protection? (Bandwidth, latency, etc.)

Network and configuration requirements are the same for level-2 and level-3 protection.

Is StorServer a similar or competitive product to everRun?

StorServer is a backup appliance, not a fault-tolerant availability solution, and addresses very different requirements. It would be more complimentary then competitive.

What virtual machines (VMware, Parallel, etc) are supported by Marathon?

Currently only Citrix XenServer, however future plans are to expand upon this.

Are there certain applications that are not suited for everRun, such as I/O or compute intensive apps? Home does DR configurations affect performance?

This is very dependent on the configuration of the server, the VM, the storage and all other components. Appropriate best practices should be followed to ensure optimal performance for all applications.

Can Marathon support physical to vm HA? Does Marathon’s product fully support FC/iSCSI SAN shared storage between protected physical and/or vm pairs? Does Marathon product support local site HA server pair with a third node at a remote site in the event of site failure? Does Marathon product have latency limitations?

Marathon offers solutions for physical and virtual servers. These solutions utilize the same proven fault tolerant technologies however are independent of each other. everRun VM supports any type of storage that is supported by XenServer. Fault tolerance is configured using two VM’s. However we will soon be releasing an asynchronous solution that will allow a third replicated system at a local or remote site. Because everRun VM is a synchronous solution there is a latency requirement of 10ms round-trip between hosts. Our asynchronous solution will not have any latency requirements.

What is the pricing of everRun VM?

everRun VM lists at $4500 when bundled with XenServer Enterprise, and $2000 if you already have XenServer.

Thanks for all of your interest and questions.

A research report by IDC’s virtualization guru, John Humphreys, The Future of Virtualization: Leveraging Mobility to Move Beyond Consolidation highlights the fact that the automatic restart used by most high availability solutions for virtualization fails to deliver what most customers really want and need. Here is what John has to say:

“To address unplanned downtime today virtualization companies are providing an automatic restart capability if the hypervisor or host go down for whatever reason. While this is a good start to trying to combat the lost revenue associated with unplanned outages, ultimately knowing what is happening at the hypervisor and hardware layers fails to deliver customers what they most want — application-level awareness and action. In this way, current HA solutions in the virtualization market are “blind from the waist up.” That is, they do not know what is happening inside the virtual machine. They do not know if the operating system or application has stopped working, and that is ultimately what IT professionals charged with delivering application services most care to know.”

If you would like to learn more about high availability for virtualization, how to get application-level awareness and what that can buy you, we encourage you to join the webinar Thursday, June 26 at 11:30 EST. with John Humphreys (IDC), Simon Crosby (Citrix) and Jerry Melnick (Marathon).

Do you know what capacity of your server is currently being utilized by your organization? No? Well you should. If you can recognize where the gaps in your current server environments are, then it’s easier to analyze the potential savings and opportunities for deploying green technology.

Each year on average an organizations data center only outputs 10-15% of its total processing capacity. By deploying a virtualization strategy, organizations can raise their hardware use to 70-80% resulting in a much more efficient use of corporate capital.

We’ve seen for quite some time now that executives are still iffy on whether or not to deploy a virtualization strategy. For the most part they understand the benefits: reducing energy expenditures, consolidating physical server space, decreasing their environmental footprint, etc. What seem to be the common causes for concern are the effects suffered during the deployment – fear of data loss and the possibility of downtime.

If VARs introduce their customers to high availability technology, such as everRun VM, and offer it alongside their virtualization solutions, then customers will increase their willingness to virtualize their applications – knowing they will be protected from downtime and data loss.

This week, Steve Keilen, VP of Marketing for Marathon, discussed the green side of everRun with eWeek Channel Insider and how it has aided VARs.

What green strategies does your organization currently have in place to maximize productivity and cut energy costs?

As demand rises for IT managers and C-level executives to embrace virtualization, we thought it would be worthwhile to share our insights into adopting server virtualization. The tips below are designed to help companies determine if server virtualization is right for them and how they should prepare to ensure a successful initial implementation.

Tip #1 – Make the business case for server virtualization

Before implementing server virtualization, IT executives should assess whether the technology will provide a reasonable return on investment. They should first take a look at how they are using servers today and ask themselves:

• Do they have common applications running on a number of different servers?
• Do they have enough servers that could and should be consolidated? Is the number of applications increasing and the capacity required for the applications continuing to expand?
• Do they expect the number of servers they have to buy each year to increase? If so, by how much?
• Is the business planning to undertake other large-scale technology implementations, and if so, how will this fit with a possible virtualization development?

In short, the IT department has to make a strong business case and justify the virtualization investment to ensure executive management support. To help conduct a quick assessment, ROI calculators are available from VMware and Marathon. Marathon also has a webinar available with John Humphreys, Program Vice President, Virtualization Software for IDC, “Making the Business Case for Server Virtualization,” in which John provides essential guidance in making your business case.

Tip #2 – Consider the license and support implications

IT managers need investigate what, if any, impact virtualization will have on their application licenses and support. Depending on the application, the original licensing terms and conditions may no longer apply after the applications have been migrated to the virtualized environment. In addition, it may be that the providers of some of the software applications do not support virtualization systems, and are unwilling to offer technical support for the applications after the migration to a virtualized environment.

Tip #3 – Afford to spend the time to plan

As any IT professional knows, implementing a new system requires dedicated resources, budget and time. Industry experts have estimated that the planning stage constitutes 90% of a virtualization implementation project. The actual migration is relatively simple to undertake provided that the implementation has been well-planned. Any system information to be migrated should be collated and backed-up up to six months before the start of the migration. IT managers should remember to assess how much hardware each virtual machine needs in order to operate efficiently. They also need to ensure that the number of virtual environments residing in a single hardware does not sprawl out of control - this could have serious consequences on the stability of the environment and application availability. A thorough implementation plan will help businesses minimize any hiccups that might arise.

Tip #4 – Assess levels of application availability and risk to business continuity

Despite the many benefits of virtualization, businesses are beginning to realize that there are risks associated with the technology. While virtualization is useful for protecting applications from planned downtime, protecting virtual environments from unplanned downtime is a different matter. Today, the cost of just a few minutes of unplanned downtime can be hugely detrimental and with virtual environments the risk is greater because server consolidation often results in a single point of failure for multiple applications. Businesses should therefore consider a solution that combines virtualization technology with the high availability protection necessary to keep the business going through disruptions.

Tip #5 – Demonstrate that virtualization won’t impact end users

After the implementation, it is critical to demonstrate to executive management that virtualization can be accomplished without hindering applications performance and without diminishing service to end users. IT managers should monitor closely the performance of initial deployments, and if necessary, modify hardware and networking configurations to ensure that the virtual environment is completely transparent to end-users.

Emerging virtualization technologies are opening doors by removing existing barriers of entry such as cost and complexity. More and more businesses of different sizes are starting to reap the benefits of server virtualization. But, before embarking on a virtualization project, organizations should assess their needs carefully, choose the right technology, make sure the implementation doesn’t impact end user performance - and start small.

A common question we get from analysts and something that continues to come up in discussions (see Brian Madden’s blog) is why we developed everRun VM for XenSource and not VMware. One of the biggest obstacles in developing a version of our software for protecting virtual environments was making a strategic decision on which hypervisor platform to develop for initially. Some of the key factors that weighed in on our decision were:

• Virtualization platform market share
• Robustness of the virtualization platform
• Performance of the virtualization platform
• Openness of the architecture
• Virtualization vendor’s approach to partnerships
• Compatibility with future Microsoft virtualization platforms

Although VMware was the clear market leader, for most of the criteria, XenSource (now Citrix Virtualization and Management Division) was a much better fit. To acheive the superior availability that everRun VM uniquely provides, it had to be tightly integrated with the hypervisor, the openness of the architecture was very important. And since our solution would be directed at virtualizing applications that weren’t being virtualized yet, in part due to concerns about their performance in virtual machines, the near “bare-metal” performance of XenServer was also a major advantage. XenSource’s philosophy of growing through an ecosystem of technology partners gave us the confidence that they would get the technical, management and marketing support required to achieve our time-to-market objectives. Finally, because of the company’s relationship with Microsoft and the planned interoperability between the XenServer platform and Microsoft’s Hyper-V, we are confident that developing for XenServer now would provide the shortest path to supporting Microsoft Hyper-V when it becomes available.
