Red Hat and Virtualization

September 19th, 2011    Posted in virtualization

Being the vendor of Linux, Red Hat would want that its customer should run its technologies on Linux but the customers need to run RHEV i.e. Red Hat Enterprise Virtualization management system on Microsoft windows. This concept has changed now as a result the management system has been re-written so that java applications would run on top of a Red Hat Enterprise Linux server. For authentication of work, RHEV supports Active Directory. It also allows opening up the source of PostgreSQL database. According to thadani, the newly upgraded RHEV provide zero-downtime up-gradation. This updated windows free management would not cost you anything extra than what has been charged previously. They also let you know about the reason for which you will pay for i.e. enterprises needs to count the CPU sockets on the basis of the number used by them and accordingly they will be paying for the same.

The best part would be that Red Hat charges you one-seventh of the cost of VMware. Due to the addition of the new management server, we can come across a big change in the new version of KVM i.e. RHEV 3.0. This new version is simply hold to power the solution as a core virtualization hypervisor. The underlying hypervisor has been replaced with new KVM which is about to ship in RHEL 6.2. Along with this new up gradation, they have also considered performance enhancements which includes various features such as:-

  • Transparent Huge Pages for database performance,
  • ¬†paravirtualized interrupt controllers,
  • a sync I/O
  • An entire rewrite of the networking infrastructure.

They have also explained that the stack of the network has been moved from user to kernel space so that it can deliver better performance. Another most important feature of this system is that it can scale up to 128 CPUs with 2 TB of RAM at the host level providing for large virtual machines. It also provides built-in reporting infrastructure which help to leverages an embedded Jasper Reports engine. This engine provides historic views on usage and management so that it becomes easy for the users to manage the system.

Therefore, we can conclude the fact they have succeeded in grabbing more and more customers across the industry segments which has made RHEV 3.0 available in beta. It has been observed that Red Hat customers including major players like Qualcom, BNP Paribas and DreamWorks use RHEV.
