Last Monday, HP announced the availability of their Moonshot system. In a word, it is about packaging a large number of nodes under-10 W computation or storage in a fraction of the space of what has been available so far on the server market business. HP are currently delivering densities calculation servers 45 by 4.3U chassis, which means that 450 servers per rack. HP also visualized future densities up to 180 servers per chassis or 1800 servers per rack. Although each system may not be as powerful as traditional x86 server, you win a large number of servers and consuming much less energy.
Virtualization Is Dead?
On the face of it, HP Moonshot the architecture lends itself to "physicalization", a term coined to describe the movement in some areas in an architecture in which only some workloads - perhaps to four - run on a single host. In such a scenario, what role would have virtualization?
The answer is, of course, that there is definitely a place for hypervisors, but it looks very different from the way we use them today.
Virtualization & Manageability
HP Moonshot will lead to tens of thousands of servers in a single line of a data center. A user of this infrastructure would not care what exact server where they running out: they just want their workload to keep running. Thus, administrators will move workloads around (for example to take the machines into and out of maintenance). The best way to do this is to use a virtualization platform.
Of course, this does not mean that you will necessarily need all the features of a traditional virtualization product. bloating or memory page sharing, for example, is not useful if you run a two virtual machines. As we move into the future with Moonshot what you will need is a way to manage the complexity of many machines. That's where an orchestration layer is necessary.
Your Very Own Cloud
As service providers and enterprises start to deploy Moonshot systems, even a small deployment means a large number of servers. Provide the ability to divide this infrastructure across multiple tenants, with the system allocate servers to users on request (not someone who needs to physically carry out the distribution), and monitoring / billing for usage becomes key. That is why the orchestration layers as Apache CloudStack (on which is based the Citrix CloudPlatform) and OpenStack are really important for the adoption HP Moonshot grows.
Xen is armed
Today, the original HP Moonshot servers are based Intel Atom. All x86 hypervisor must be compatible; However, HP plans to rapidly introduce servers based on ARM in Moonshot. There is currently a lot of interest surrounding the potential of ARM in servers, and the recent announcement of the Xen project that the Xen 4.3 hypervisor will support ARM architectures help enable and grow this ecosystem.
Citrix is a major contributor to Xen project and recently announced that it will join the Linaro Enterprise Group (LEG). Meanwhile, Citrix has also worked with the CloudStack Calxeda port management ARM-based bare metal servers. We are excited about the possibilities this market holds, and you can expect to see more activity surrounding virtualization ARM servers and orchestration of us in the future!
So What
Many people are? will start investigating alternative processing architectures Moonshot after the announcement of HP, and there will be a significant need for both virtualization and cloud orchestration to help manage deployments. Citrix and HP are well positioned to jointly deliver solutions using XenServer, Apache CloudStack and OpenStack, and Moonshot system.
