Scalable NAS Room
Scale capacity and performance for business-critical data with HP Scalable NAS
Three-quarters of IT executives surveyed believe virtualization by itself can play a major role in an enterprise disaster recovery plan, but it in no way represents a complete answer to a DR strategy, according to a "State of Disaster Recovery" survey released June 25 by market researcher Harris Interactive.
While many IT decision makers say they have deployed virtualization in a production setting, survey data indicated that most had not yet utilized it in a disaster recovery situation.
A full-fledged disaster recovery system using virtualization replicates the system and all its data to an off-site location away from the main enterprise data center. In the event of the main data center going offline and out of action, virtual machines replicated at the backup location continue to keep the workloads running smoothly, with little or no latency in daily production.
However, many companies are not able to deploy separate backup data center locations to provide the complete data recovery system, relying instead on failover to separate storage arrays and servers within the same physical building.
"The Achilles heel of many virtualized IT environments is they depend on a single data center to execute system failover should an outage occur," said Don Norbeck, technology officer at SunGard Availability Services. "A recovery strategy with no off-site data center can result in no recovery."
Seventy-four percent of survey respondents indicated that virtualization can play a major role but is not a total solution for disaster recovery plans. One-quarter of IT respondents said they would never include virtualization technologies in their disaster recovery plans.
Virtualization: only nominal success in DR thus far
Sixty percent of respondents said they have virtualization in place now as a recovery tool from unplanned outages; only 29 percent said they have used it successfully. Eight percent said they used virtualization, but that it didn't work to their satisfaction.
Another 29 percent of IT decision makers say they have deployed virtualization but not yet used it as a tool for disaster recovery.
Over the next two years, the survey said, half of IT decision makers say they will be looking into virtualization as an option for managing unplanned outages and disaster recovery. About a quarter of IT executives say they will be looking into cloud computing and grid networking as potential options.
This survey was conducted online within the United States in March 2009 with 497 qualified respondents, including 277 business and 220 IT participants.
The survey was commissioned by SunGard Availability Services, which provides disaster recovery services, managed IT services, information availability consulting services and business continuity management software to more than 10,000 customers in North America and Europe.
Scalable NAS Resources
- Storage Consolidation Without Performance Compromise
Given the current state of the economy, storage consolidation is now a high priority for every IT organization. But for IT organizations running performance-sensitive applications, storage consolidation can be a major challenge.
- Demystifying NAS Clustering
Data storage needs are on the rise. But beyond simply providing more raw capacity, today¿s storage solutions must also be easy to provision and manage, energy-efficient, and highly scalable in performance and capacity. Download this white paper to learn about HP NAS clustering solutions that help meet today¿s rapidly changing storage requirements.
- Windows File Server Consolidation: Reference Architecture and Configurations
Organizations that deploy Microsoft Windows file servers receive many useful services. Traditional file servers, however, lack scalability, so organizations must add file servers as their data storage needs grow. This results in server sprawl, which leads to low utilization of the file servers and sub-optimal availability of storage. Learn how organizations benefit from consolidating their Windows file serving environments using HP Scalable NAS, a highly scalable, manageable and available storage solution.

- Scalable NAS: Insights from customers, analysts and HP
When IT administrators are looking for networked storage solutions, they often look to NAS because they can use the Ethernet infrastructure they are familiar with to build pools of storage for significantly less money than SAN with equivalent capacity. Unfortunately, traditional NAS doesn't scale and administrators find themselves having to add NAS platforms to keep up with growing storage demands. As a result, many administrators have started looking for alternative solutions.
