Red Hat Provides Leading Healthcare Institution with a More Cost-Effective, Dependable, and Secure Virtualization Solution
March 20, 2012
A leading healthcare instituion set out to find a more cost-effective virtualization technology with better support and reliability. With Red Hat Enterprise Virtualization, the healthcare provider has reduced datacenter costs and much more.
"We now have a new mantra within our organization: ‘If it can go on Red Hat, then move it to Red Hat.” – Jeffrey Allred, manager of network resources, leading healthcare institution

Ranked as one of the nation’s top cancer hospitals by U.S. News & World Report, the leading healthcare institution is an internationally recognized medical organization that combines cancer care and research together under one comprehensive system. With a network of more than 300 researchers and physicians as well as 500 clinical staff, the leading healthcare institution serves nearly 6,000 new cancer patients from around the world each year. The leading healthcare provider is a National Cancer Center Institute-designated cancer center — one of only 40 in the nation —and operates as part of the Health System. The IT team is a shared resource within the leading healthcare institution that provides integrated information systems in support of clinical and basic science biomedical research. The group provides a state-of-the-art computing infrastructure, personnel, technical support, assistance, and consultation in four areas: data management design, database application development, network and server management (including high-performance computing), and web application programming.
In 2006, the demand for servers was increasing, and the datacenter was growing exponentially. With a history of implementing cutting-edge solutions, the IT team decided to move to a virtualization infrastructure to manage this growth. After a small pilot on VMware, the IT team rolled out two deployments over time, one using VMware and the majority of their virtualization workload on to Virtual Iron’s VI-Center.
The IT team team was confident about using virtualization technology, but questioned whether it had chosen the right vendor, especially after Virtual Iron ceased existing as an independent company. Not only was the product they were using reaching end of life, the IT team also experienced some unfortunate support experiences with the new owner of the technology. In addition, a blade server was beginning to fail in one of its VMware clusters, and the maintenance renewal was quickly approaching. Rather than invest money into older hardware and an even older VMware installation, the IT team decided to start looking for other options.
Because the leading healthcare institution is 100 percent grant funded, money is always a key concern when making purchasing decisions. After running the numbers, the team ruled out VMware because it was not providing enough value for the increasing price tag. The IT team also considered other alternatives such as Xen and Oracle VM, but the vendor that particularly stood out was Red Hat.
“I’ve always been a Red Hat fan,” said Jeffrey Allred, manager of network resources, leading healthcare institution. “Knowing how stable the Red Hat Enterprise Linux platform was, I was eager to learn more about Red Hat’s virtualization offering, especially given that it is based on Kernel-based Virtual Machine (KVM) technology.” Red Hat Enterprise Virtualization for Servers offered all the features the manager and his team were looking for at a cost-competitive price. “With Red Hat Enterprise Virtualization, we could buy both the hardware and virtualization solution for the same amount of money that VMware charged for the virtualization software alone.
“Additionally given Red Hat’s solid reputation in the datacenter and its position as the leading Linux vendor, we feel secure that Red Hat is in a solid position to continue to offer and expand its infrastructure product portfolio over the longterm,” said Allred. “And then considering our initial experiences with Oracle’s support team, the choice was especially obvious."
The IT team made a successful transition into its new Red Hat Enterprise Virtualization environment. The team used Acronis Backup & Recovery Virtual Edition software to migrate from its existing platform to Red Hat Enterprise Virtualization. Today, leading healthcare institution’s datacenter houses 85 servers running both Red Hat Enterprise Linux and Microsoft Windows. Roughly 65-75 percent of those servers are virtualized through Red Hat Enterprise Virtualization. As part of its initial deployment, the IT team rolled out five two-socket server virtualization hosts, each supporting 11 virtual machines, for a total of 55 virtual machines.
The servers are two-socket, six-core HP AMD blade servers housed in an HP BladeSystem c7000 enclosure. Currently, about 35 percent of the virtual machines are running Red Hat Enterprise Linux, with the remaining running on Windows. And there are plans to deploy more Red Hat Enterprise Linux instances. “The ratio of Red Hat servers to Windows servers will definitely change as we move into the future.”
As for storage, the IT team selected the storage area network (SAN) route with RAID 6, in the form of an HP StorageWorks EVA4400 storage array with 96 terabyte capacity. This new infrastructure supports approximately 1,000 users, ranging from research staff to family support groups, who rely on it for research, clinical work, and the support of application and database workloads. Database servers include Oracle, MySQL, and Microsoft.
The manager and the IT team department are especially happy with how easy it is to maintain their new virtualization environment with the management capabilities provided as part of the Red Hat Enterprise Virtualization for Servers solution. “The graphical user interface in Red Hat Enterprise Virtualization Manager is very intuitive and easy to use,” said Allred. “You don’t need an engineering degree to figure out what you’re doing. If I see our main VM file server start to consume too much of the host server resources, I can use the live migration feature to easily move it to another hypervisor that is not seeing a lot of CPU usage. Being able to do that on the fly and transparent
to users is extremely valuable."
The IT team takes advantage of all of Red Hat Enterprise Virtualization Manager’s capabilities, from its high availability feature that enables the prioritization of virtual machine restarts, to the maintenance management feature that enables patches to be applied to the hypervisor host.
There’s the obvious cost savings associated with server consolidation, as well as the greater flexibility and high availability through virtualization. However, with Red Hat Enterprise Virtualization, the IT team also gets unmatched reliability at a much lower price than other solutions. “The stability of the Red Hat platform cannot be beat,” said Allred. “The only time I have to reboot a Red Hat machine is when I upgrade the kernel. In comparison, Windows requires a reboot at least once a month on ’Patch Tuesday.’”
The IT team also recognizes compelling performance improvements for its virtual machines, because of Red Hat Enterprise Virtualization. “We’ve definitely noticed improved responsiveness and performance from our Windows and Red Hat Enterprise Linux virtual machines, which are configured identically to our old VMware/Virtual Iron cluster,” said Allred. “From boot up to application performance, they perform better on Red Hat Enterprise Virtualization.”
This greater performance translates into improved productivity for its users. Furthermore, with its integration into the Linux kernel, Red Hat Enterprise Virtualization for Servers’ KVM-based hypervisor provides all of the technology advances of Linux for virtualization. The IT team also takes advantage of Red Hat’s industry-leading security support team. “In addition to a greater sense of security with Red Hat, we also get a higher quality of support,” said Allred. “With Red Hat, I always get an explanation of how things work, whereas with our old solution, it was positioned more as black magic. Red Hat’s technical expertise, both within its support center and field teams, is world class. Its a world of difference form other virtualization vendors out there.”
The organization also takes comfort in the robust security capabilities of Red Hat Enterprise Virtualization. With SELinux (Security-Enhanced Linux) as part of the Red Hat Enterprise Virtualization hypervisor kernel, security is built in from the ground up and not a bolt-on feature. Acronis was critical to the IT team’s migration to Red Hat Enterprise Virtualization. Red Hat does have a fully supported migration path for VMware, but does not support migrations from the older vSphere 3.1. For this work the IT team turned to the Acronis Backup and Recovery 11 Virtual Edition, which is certified for Red Hat Enterprise Virtualization and includes P2V, V2V, and V2P migration capabilities. The migration solution is platform-independent and took the worry out of the platform-specific issues that leading healthcare institution and the IT team previously encountered. The migration process was very fast, and the VMs just started working once they were on Red Hat Enterprise Virtualization. “It’s a tremendous feeling to be helping a customer like leading healthcare institution and the IT team with open source virtualization technology in their mission to fight and defeat such a terrible disease. And the team at the IT team has been great to work with,” said David Huff, solution architect at Red Hat.
Looking ahead, Allred reflects, “Our c7000 blade enclosure and SAN have a lot of room for expansion, so we will be looking at a desktop virtualization at some point.” He has no doubt that they will look to Red Hat to support this desktop infrastructure as well. “We now have a new mantra within our organization: If it can go on Red Hat, move it to Red Hat.”
