Four-node configuration for Hyper-V using StarWind iSCSI SAN

IT department is now a part of any infrastructure that undertakes responsibility of making business process safe and solid. It means that, in order to go with the times and provide up-to-date services, companies must invest resources – budgets and man-hours – in IT. Business continuity is extremely critical today, because just a short operations’ break can result in a large financial loss.

Manufacturing businesses and financial services actively turn regard on modernization and updating their IT-infrastructures. Only this approach suggests intensive and effective business growth, and the key requirement for business-continuity maintenance is High Availability of applications and data.

High Availability mechanism ensures that in case of failure of any node of the environment another node takes over all critical processes and keeps delivering your data intact and safe without any delays. This process is non-transparent for users – they do not notice any operational downtime and continue working with data in a normal mode.

With usage of HA approach, IT-departments can significantly increase system uptime and multiply ROI.

High Availability of disk storages is a key condition when it is about Hyper-V virtual machines, which need high protection level for being in operation in any case of failure.

Microsoft Hyper-V technology is a powerful virtualization platform that is designed for building and managing virtualized environments. It provides many reliable features and can be easily integrated into any IT-infrastructure.

Combining High Availability with Hyper-V virtual machines is a great benefit for your com¬pany. It means not only to save money on physical hardware, but also to be able to failover to another server in the events of hardware failure and keep the virtual machine running.

StarWind Software Inc. offers solution for building two main Hyper-V-based configurations to provide companies with reliable and high available storages: a two-node one and a four-node one. The difference between them lies principally in cost.

The four-node configuration is an excellent solution for virtualized server environments of companies with substantial IT budgets. It is somewhat expensive than a two-node configuration, but it provides very high performance level and ensures double reliability.

(It`s worth mentioning that both configurations are still much lower in cost than other proprietary solutions.)

StarWind iSCSI SAN can be installed on any Windows server (Microsoft Windows Server 2008 R2 is recommended). In order to create failover configuration four servers are used - two of them serve as storage nodes and two other serve as failover cluster nodes. This full-redundant scheme ensures fault-tolerance and High Availability of your storage.



The whole process consists of several simple steps, which will turn your existing servers to a high-performance SAN within 30 minutes:

• Preparing Shared Storage (Configuring StarWind)
• Configuring Windows Hyper-V Servers
• Creating cluster
• Making the VM highly available

Using the StarWind iSCSI SAN solution Hyper-V you obtain a reliable, manageable, and scalable iSCSI SAN that completely protects your Hyper-V environment in case of a failure.

The four-node configuration created with StarWind iSCSI SAN for Hyper-V provides the following advantages:

• High performance
• Optimization of your virtualized environment
• Efficient use of resources
• Reduction of downtime
• Faster Disaster Recovery
• Faster Backups
• Cost-effective solution
