Reduced costs by reducing amount of servers

For how long have you used this solution? - 1 year

Which features are most valuable? - Live migration

Can you give an example of how this solution has improved the way your organization functions? -We where able to reduce the amount of servers. This has reduced our costs significantly.

What areas of this solution have room for improvement? - The interface is sometimes not logical and previous versions where not so stable but luckily this has been mostly resolved.

Did you encounter any issues with deployment, stability or scalability? If so, please describe. - Stability and bugs in previous 2.x versions

Did you previously use a different solution and if so, why did you switch? - No this was our first virtual platform

Before choosing this solution, did you evaluate other options? If so, which ones? - The choice was clear for us; it had to be open-source with commercial support

How would you rate the level of customer service and technical support? - The support we got so far from redhat as customers was great. You would probably not get better elsewhere

Was the initial setup straightforward or complex? In what ways? - Straightforward. Yes there is a great guide online at redhat on how to install this

Did you implement it in-house or through a vendor team? If through a vendor, how would you rate their work? - We installed it in-house as we are reseller and integrator

What is your ROI on this solution? - There is no investment in this product. As a reseller we can use it to test for free we pay every year a fixed cost as partner.

What was your original setup cost for this solution and what is your day-to-day cost of using it? - Free for us

What advice would you give to others looking into this solution? - I would say give it a look if you are looking for a virutalization platform. Most of the things can be done with rhev and the cost is much lower then with other commercial solutions. Since version 3 this product is mature and since version 3.1 most glitches where removed.

Disclosure: The company I work for is partners with several vendors (including Red Hat) - http://www.open-future.be/solutions/partners

Patrik, I do not think you are allowed to use NFR licenses for production.

RHEV 3.2 is Quite Stable, Unlike Previous Versions

I am very pleased to say that I like Red Hat in many ways because of their innovations,working on new technology and improving day by day bringing it upto the expectations of customers with premium support available through out at all time. RHEV was launched as a web portal based access of virtual machines throughout the network which is used in organizations for different purposes with all virtualization features available today; earlier they were having problems with the product but now RHEV 3.2 is quite stable.

Disclosure: My company does not have a business relationship with this vendor other than being a customer.

RHEV is excellent due to cost, performance and security.

Valuable Features:

RHEV costs are very low compared to other Virtualization products. RHEV hypervisor supports up to 160 cores and up to 2 TB of RAM on a host machine. Performance and security are key advantages of RHEV. One of the new features are transparent huge pages, where kernel dynamically creates large memory pages for virtual machines, which improves performance for most workloads by reducing the number of times that memory is accessed. It is open source, which means that it is available for use by every one. There is a “Power user portal” feature that helps developer and IT staff with a self-service interface that allows them to provision virtual machines, define templates, and be an administrator to their own environment.

Room for Improvement:

You need to buy support from red hat and you need to renew support every year in order to keep getting support from red hat. Some features are unavailable compared to leading visualization products. RHEV hyper-visor came later into the market than other leading visualization product.

Other Advice:

RHEV hyper visor is a cost effective solution for virtualization. Its work on kernel base virtualization systems. Its usage keep growing in the market.

Very good information about how many logical and virtual CPU can be supported on different types of virtualization. However, could you please guide us where there are any significant better performances or bottlenecks when the number of CPUs are quite large.
