Since the advent of the Internet and with the exponential development of access to the network, the increasing dependence of users on network connectivity, the birth of increasingly popular online applications, the gigantic increase in the amount of information deposited on the network, the growing power of web-oriented programming languages, the birth and exponential development […]
NASA is launching its cloud computing platform called NEBULA in beta, a platform that integrates a set of open-source components into a single self-service platform. From the architecture diagram you can see database elements such as MySQL Cluster, storage network clustering solution such as the Lustre File System, elements of the Eucalyptus cloud system, Trac, […]
Despite the draft definition of NIST, National Institute of Standards and Technology, we continue to talk about Cloud Computing as if it were the technology capable of doing everything. One of these much-mentioned features is the alleged innate scalability of the technology, so let’s start with a proper understanding of scalability first: We can define […]
Some time ago in the in-depth analysis of hypervisor performance we found ourselves faced with a native problem of virtual Simmetric MultiProcessing (vSMP) which would be a methodology of Simmetric MultiProcessing (SMP), thanks to which we can assign more than one virtual CPU (vCPU) to a virtual machine. This feature would allow you to give […]
The proliferation of datacenters, the number of under-used servers, the delays and complexity in designing and implementing a reliable and scalable multi-tier infrastructure, the need of companies to no longer want to worry about the infrastructure, to no longer want to keep “in-house” system engineers and architects useful only at certain times, are finally developing […]
Months ago we underlined at the bottom of the article: http://blog.vmengine.net/2008/05/30/marten-mickos-ceo-di-mysql-a-la-sapienza-di-roma/ related to the Roman conference of MySQL at Sapienza, about the future possibilities of creating performance using the new native ZFS filesystem of Solaris and the MySQL database engine. Well something was born, thanks to some features of the phenomenal ZFS filesystem and the […]
The First National Bank of Omaha (FNBO – Nebraska, USA) wanted to insure its data center against any power outage. So they built a new “underground” data center in Omaha, lined with concrete. The facility is powered by hydrogen fuel cells, fully operational “off the grid”, not connected to the national electricity grid. “If the […]

Microsoft’s Hyper-V hypervisor is available for free download on October 2nd The Xen hypervisor, notoriously FREE in various versions, can be downloaded in the XenExpress version here The new free version of […]
Hewlett-Packard acquired LeftHand Networks on October 1 to open its market to the new logic of storage virtualization, storage clustering, or rather commodity-based storage clusters. LeftHand Networks, a pioneer in iSCSI SAN technology, offers scalable storage software for the standard hardware industry. With the LeftHand, HP’s portfolio of virtualization solutions for small and medium-sized businesses […]
