PHYSnet doubles its file serving performance

  1. 1. Case Study IBM Systems and Technology Group Education PHYSnet is responsible for providing IT services to the University of Hamburg Physics Department. It runs a large datacenter, whose systems deliver basic IT services and also the high levels of computing power needed by physics researchers at the university. Bodo Krause-Kyora, Head of Systems and Deputy Director at PHYSnet, explains: “Our researchers do a lot of number crunching, which generates huge volumes of data. To give an example, with the most complex computations, you can have something like half a terabyte of data being produced by a single calculation. We need to make sure that all of this information is readily and rapidly available.” Like many other scientific research institutions, the University of Hamburg uses OpenAFS, a distributed, open source and highly scalable network file system that enables easy and fast access to documents. This is useful for researchers, who frequently collaborate and share resources on different projects. PHYSnet doubles its file serving performance With a powerful, highly virtualized IBM solution Overview The need PHYSnet’s existing servers were not delivering the required levels of performance. The university wanted to improve file serving throughput without investing in large numbers of physical servers. The solution PHYSnet implemented a virtual distributed configuration for its OpenAFS file system using two IBM® PowerLinux™ 7R2 servers running 10 virtual Linux servers using IBM PowerVM® virtualization. The benefit The IBM PowerLinux Open Source Infrastructure Services solution has improved file system performance by 50 percent. The PowerLinux servers deliver improved economics with 30 percent less cost and five times less cooling than the competing option. Main Building, University of Hamburg Source: UHH/Schell
  2. 2. Case Study IBM Systems and Technology Group Education Lack of computing power A scaled-out environment works best for OpenAFS, as it enables the system to provide the high bandwidth required by users. PHYSnet found that its OpenAFS servers were not performing well on its Intel processor-based environment. “With the Intel-based machines, we weren’t seeing the high levels of throughput that we needed,” says Krause-Kyora. PHYSnet realized that it needed to increase file server performance, and evaluated its options. Analysis showed that it would take ten new Intel-based servers to meet the throughput requirements – representing a significant capital cost and also requiring additional investment in cooling systems. As Krause-Kyora states, “Cooling is a big constraint for us. Our datacenter was already limited on cooling capacity, and it simply wasn’t feasible for us to add ten more physical servers.” Additionally, using VMware virtualization on new Intel-based systems would have required additional investment in costly licenses for each server. These issues meant that it was not cost-effective for PHYSnet to purchase more Intel-based servers, so it looked for a solution that would allow it to obtain the high levels of throughput it needed on fewer systems, at a lower total cost of operation. Developing a virtualized solution PHYSnet had been using IBM® hardware for many years, and trusted IBM Power Systems™ machines for mission-critical IT services. The PHYSnet team approached IBM Business Partner pro-com DATENSYSTEME GmbH for advice on finding a solution that could meet its needs. In response, pro-com designed a distributed configuration for OpenAFS that was based on just two IBM PowerLinux™ 7R2 servers. To provide the system architecture needed to run OpenAFS effectively without the need for additional physical servers, pro-com proposed a virtual scale-out environment, using IBM PowerVM® to set up five virtual machines on each IBM PowerLinux server.

  3. 3. Case Study IBM Systems and Technology Group Education “The IBM solution appealed to us for a number of reasons,” notes Krause-Kyora. “We only had to invest in two physical servers as opposed to ten, and IBM PowerVM allowed us to scale out our architecture virtually instead of physically, which meant that we wouldn’t have to drastically increase our cooling capacity. Finally, as we were already running other IBM Power Systems servers, this solution allows us to take advantage of our existing knowledge without the need for additional training.” Higher performance at a lower price The new IBM PowerLinux Open Source Infrastructure Services solution allows PHYSnet to deliver services faster, with higher quality and at lower cost. File serving performance has improved by over 50 percent. As Krause-Kyora explains, “IBM PowerLinux is the best option for running OpenAFS as it can handle the high I/O requirements of the system and delivers the throughput needed to quickly access files. We would have needed to purchase significantly more Intel-based systems to achieve the same levels of file serving performance that we do with just two IBM PowerLinux servers.” The impressive throughput of the IBM PowerLinux Open Source Infrastructure Services solution also enables the organization to fully exploit the capabilities of its IBM SAN solution with IBM System Storage® DS3512 devices. PHYSnet’s storage systems are a perfect complement to the IBM PowerLinux Open Source Infrastructure solution, as they match its high throughput to prevent bottlenecks from forming. This is of particular importance to PHYSnet, as it manages a total of 600 TB of active data, with half of this being produced by the OpenAFS system. “IBM PowerLinux is the best option for running OpenAFS as it can handle the high I/O requirements of the system and delivers the throughput needed to quickly access files.” — Bodo Krause-Kyora, Head of Systems and Deputy Director at PHYSnet
  4. 4. Case Study IBM Systems and Technology Group Education Additionally, PHYSnet was able to make a 30 percent savings by investing in just two IBM PowerLinux 7R2 servers, as opposed to ten Intel-based x86 systems. Implementing fewer servers has introduced additional savings around power and cooling costs, as the new IBM PowerLinux servers use five times less cooling and electricity compared to the equivalent Intel-based servers. Bodo Krause-Kyora describes the advantages of investing in an IBM Open Source Infrastructure solution: “As we are a university organization, it is particularly important for us to spend our money wisely. IBM PowerLinux with PowerVM provides us with a solid base and gives us the flexibility to take on new projects without having to invest more money in new hardware or virtualization software.” Virtual scale out with IBM PowerVM PHYSnet has maximized the cost savings and efficiency of its new solution by taking advantage of the advanced virtualization features of IBM PowerVM, which provides market-leading virtualization for PowerLinux servers. IBM invested heavily in optimizing its PowerVM technology for IBM PowerLinux, and the solution has helped PHYSnet to maximize its IT investment while reducing cost and complexity. By virtually scaling out its server architecture with ten virtual machines, PHYSnet gained the increased throughput it needed without costly investment in a large amount of physical servers. Equally, the IT team has avoided the need to manage an additional eight physical servers, leaving staff free to focus on other tasks and turn operational cost into investment. The IBM PowerLinux solution with built-in IBM PowerVM is also significantly less expensive than the competing Intel and VMware solution initially considered by the organization. As Krause-Kyora states, “IBM PowerLinux offers a virtualization technology with easy and effective manageability for virtual server environments. It allows us to increase our server utilization and reduce our total cost of operation, at a much lower price than with VMware.” “With the IBM PowerLinux Open Source Infrastructure Services solution, we can operate our OpenAFS system reliably, and there is still room to put other infrastructure services on additional virtual machines.” — Bodo Krause-Kyora, Head of Systems and Deputy Director at PHYSnet
  5. 5. Case Study IBM Systems and Technology Group Education Even though PHYSnet deployed just two IBM PowerLinux servers, the new virtualized configuration meets the need for increased file serving performance, and still has the capacity to run additional workloads. “With the IBM PowerLinux Open Source Infrastructure Services solution, we can operate our OpenAFS system reliably, and there is still room to put other infrastructure services on additional virtual machines,” says Krause-Kyora. “We are currently taking advantage of this additional capacity to support 4,500 users on our central email servers, and we have plans to migrate our IBM Tivoli® Storage Manager application to the new PowerLinux servers. IBM PowerVM lets us easily balance the server workload from a single point of management. In this way we are able to get optimal response times from each application.” Looking ahead, the organization plans to exploit other advanced virtualization features of the system, such as PowerVM Live Partition Mobility, which allows running virtual machines to be moved from one physical server to another with no impact to end users. This optional feature is offered as part of IBM PowerVM for IBM PowerLinux, and will further enhance the flexibility and availability of PHYSnet’s PowerLinux Open Source Infrastructure Services solution.
