Virtualized Disaster Recovery: Obvious Benefits, Hidden Obstacles

  1. 1. issue number 1 // april 2008 Virtualized Disaster Recovery: Obvious Benefits, Hidden Obstacles Virtualization alone—no matter how advanced— will not be enough to save you in a disaster if you haven’t planned for a virtual recovery. “are you ready to expand your virtual machines?” As an IT Director of a medium-sized (or any-sized) company with virtual servers, you’ve experienced the benefits of virtualization. Virtual machines (VM) have cut your infrastructure costs and increased your flexibility to respond to changing business demands. Senior executives and internal departments have seen the advantages inherent in virtualization and want to increase the number of virtual servers. You want to expand the number of virtual servers to meet the growing need, but you also worry about “server sprawl” given your budget and ROI requirements. When you overlay the need to protect these additional virtual servers and their applications in the event of an unplanned outage, you worry even more about the complexity of it all and your ever-tightening budget.
  2. 2. “or, are you ready for your first virtual machines?” servers on the same brand or kind of physical x86 hardware. As an IT Director of a small or mid-sized business with A virtual server tuned for virtual recovery doesn’t know the limited IT resources, you’ve been evaluating virtualization difference. but want to make sure you plan and execute a cost effective solution. As you bring the significant benefits of VMs into the power of Green it your data center for the first time, you also need to think Fewer servers operating at higher utilization rates can about what a disruption means to your disaster recovery reduce the energy needed to run and cool data centers. plans and RTOs in a virtualized production and back-up Energy savings are attractive to customers and vendors environment. alike when paying out the initial investment in virtualization. Whether you are expanding your virtual capacity Better yet, your customers (and ours) are increasingly or are about to embrace virtualization, will you be seeking green suppliers as concern increases over their own and vendors’ carbon footprints. ready for vm disaster recovery? If you get that dreaded “call in the middle of the night”— the one that tells you the cooling has failed and the server virtualization heightens both opportunities is fried, or that the data center is soggy from a flood, or and risks. the power is down and out for the count — will you have Virtualization’s single biggest benefit, more servers a disaster recovery plan and processes that back-up and with less hardware, is the much needed solution to the restore your virtual server environment? geometric increase in applications and data, the rising expectations of IT, and the ever-tightening budget and So, before you exploit virtualization even more or introduce productivity demands. IT Directors can now increase it into your data center, now is the time to prepare the utilization, respond flexibly to internal and external plan, processes, personnel, and configurations necessary priorities and reduce infrastructure costs. Virtualization for virtualized DR. has given IT directors and staff more control, agility, and sunGard availability services helps you capacity to transform IT from its support role to a strategic maximize the benefits and navigate the obstacles driver of core competencies, competitive advantage and in a virtualized disaster recovery plan and business results. Yet, it is not without multiple layers of risk. implementation. it directors and staff who are new to virtualization may think virtual back-up and recovery are easier. Obvious Benefits: How it’s more difficult. here’s why. virtualization improves DR portability Hidden Obstacles: Today, virtualized disaster recovery represents an Look before you leap. innovative, yet practical application of virtualization’s greatest feature—portability. Virtualized DR facilitates a common mistake failover from one partition to another partition in the same It’s impossible to ensure the true availability of VM within server or to another server located in the same data center. the same server or to another server within the same data This same portability facilitates faster recovery times when center when a disaster compromises an entire data center. third-parties, like SunGard, provide off-site back-up and These single location environments are vulnerable to the restoration in virtualized environments. same devastating threats as non-virtualized environments. Remote back-up is the only solution. What’s more, the Faster recovery times re-staging of images increases the need for remote-back SunGard takes snapshots (images) of your infrastructure and up. Recovery time and recovery point objectives go out the replicates them in virtual servers off-site.

  3. 3. “Virtualization is a disruptive technology with great transformational potential, but it is in danger of becoming all disruption and little benefit to companies’ infrastructure and businesses without the people, processes, and technologies working in harmony.” don norbeck, sunGard availability services director, product development vms: higher criticality than non-virtual servers As virtual machines replace multiple physical servers, VMs become increasingly critical in their support of operating systems, applications, processes and data that drive your business. Despite the overall “green’ advantage of reducing the number of servers, a single server hosting multiple VMs requires more power and therefore more cooling. Something as simple as a pulled plug could cause a major failure. look to sunGard SunGard’s virtualization-based infrastructure and services help simplify recovery, testing, quality assurance and production applications for enterprises striving for information availability at all times. SunGard’s disaster recovery and AdvancedRecoverySM capabilities provide businesses with options for risk mitigation; for data monitoring, managing, and protecting; and for rapid hardware provisioning. new dimensions of complexity Virtualization places greater emphasis on a comprehensive understanding of interdependencies—that is, how a change to a particular hardware element may impact another infrastructure element and the applications and operating system instances that element supports. With virtualization, the task of taking and maintaining inventory of servers, their application workload roles or identities (including systems and application software tied to each specific server model) becomes more difficult and critical, while the interdependencies multiply and become more complex. Most virtualization initiatives consider the basics— overlapping input/output or scheduling around peaks—but do not consider the importance of availability requirements in the overall design. Managing complexity within the tense situation of an unplanned outage can not depend on ad hoc actions. look to sunGard talk to us about your SunGard understands the criticality of virtual servers and the business workloads that run on them, which is why we developed a SunGard Virtualization virtualization needs and Assessment consulting solution.
