VM HA Can Be Easy & Affordable for SMBsUsing affordable yet sophisticated Drobo shared storage to maximize high availability for Microsoft Hyper-V™
Businesses of all sizes receive great benefits from virtualizing their servers, and many small businesses have already deployed server virtualization. Depending on the hypervisor, there can still be significant costs when it comes to high availability features such as failover and live migration. And when SMBs want to implement a SAN for the first time, they find that networking and storage costs are greater than their savings from lowever server costs.
A shared SAN allows all servers to see the same storage, enabling movement of VMs and applications across redundant server infrastructure - opening up tremendous flexibility; applications can be moved without impacting user access or uptime. Since Hyper-V is part of Windows Server 2008 R2, SMBs can continue to leverage their individual skills with a minimal learning curve. Drobo storage integrates just as easily, with no learning curve required to manage SAN storage.
Businesses of all sizes receive great benefits from virtualizing their servers, and many small businesses have already consolidated servers using virtualization. Depending on the hypervisor, there can still be significant costs when it comes to high availability features such as failover and live migration. In addition to these software costs, dependencies on network and storage infrastructure can be a limiting factor for smaller organizations. When choosing a virtualization strategy, SMBs often consider deploying a SAN for the first time, and they find that networking and storage costs are greater than the savings from lower server costs.
The right infrastructure to support server virtualization enables higher availability, which justifies the investment. With comparable TCO, uptime for applications is dramatically increased. Every IT manager at a small company can also benefit from the time and effort savings enabled by virtualization. Maintenance and testing are typically performed on weekends and during off-hours (often in the middle of the night!) to avoid affecting application uptime. Planned downtime can be reduced or even eliminated via live migration, allowing IT managers in smaller organizations to do more of their work during working hours without impacting application uptime.
Shared SAN allows all servers to see the same storage, enabling movement of VMs and applications across redundant server infrastructure. This architecture opens up tremendous flexibility and IT managers can move applications without impacting user access or uptime.
This is a life saver when it comes to maintenance— move a VM and application, perform maintenance, migrate back--without users even noticing. Without a SAN, VMs are limited to one physical server and its direct-attached storage, and are subject to downtime for maintenance or even extended downtime in the event of a failure.
Since Hyper-V is part of Windows Server 2008 R2, it provides great value to SMBs who can continue to leverage their individual skills with a minimal learning curve. Customers can use a single set of tools to manage both their physical and virtual resources. It easily plugs into customer IT infrastructure, because existing patching, provisioning, management, support tools, and processes can all be leveraged. Drobo storage integrates just as easily, with no learning curve required to manage SAN storage.

How To Build It
To provide HA in a VMware environment in one working day:
- Install Drobo Dashboard on management server (can be on a VM).
- Deploy iSCSI SAN storage, easy one-click setup with Drobo, configure SmartVolumes.
- If not already complete, enable Windows Clustering and Hyper-V
- Configure the iSCSI Initiator, activate and format Drobo volumes
- Configure the Microsoft cluster and provision Hyper-V Virtual Machines
- Test a live migration, you have mobility and HA!
Where Drobo is Different
SAN storage is a must if you want to maximize mobility and availability for Hyper-V. Fibre Channel SANs have a high entry cost, preventing companies with smaller configurations and budgets from participating. iSCSI can be lower in price, but many iSCSI arrays still cost several tens of thousands of dollars for each system and are considered high-cost by most measures. Vendors claim that iSCSI arrays are easy to use and deploy, but most are built with large enterprises in mind.
Drobo provides superior data protection with BeyondRAID™ technology, in easy-to-use and affordable packages that are especially designed for SMBs. With failover and live migration built into Hyper-V at no additional cost, customers can buy two iSCSI SAN arrays for disaster recovery (DR) for less than half the cost of most midrange iSCSI arrays. With Drobo, there is no reason you cannot reap the benefits of a highly available virtualized environment.
