Reading Time: 2 minutesA3 Technology Live! is a one-day event, organized by A3 Communications, where up to four vendors showcase their technologies in action to a group of technical journalists, bloggers and analysts. A combination of presentations and demos allows each company to present its solutions with a much higher level of detail than is usually possible in traditional briefings. A highly interactive day for all participants.  Each editions has 3-4 companies, usually storage related, presenting their vision and/or products.

Reading Time: 3 minutesAfter cloning VMs that are running “recent” version of Ubuntu as Guest Operating System (OS) from VM template or a parent VM, the new VMs acquire the same DHCP IP addresses from the DHCP server, no matter if guest customization is applied or not… also if the two VMs have different MAC addressess. And doesn’t matter the type of hypervisor that you are using… but, of course, VMware has documented this issue in this article: Cloned VM acquires the same DHCP IP address towards guest customization process (KB 82229).

Reading Time: 2 minutesGreenfield and brownfield are terms usually used in factory planning and facilities engineering to describe two different approaches to developing or expanding manufacturing facilities. But they are also used in IT to define different deployment scenarios.

Reading Time: 3 minutesAs you know the VMUG membership is completly free as also most of the benefits, including the online resources, local meeting and UserConf events (some events may have a fee depending by the local VMUG, but almost are for free). But, if you want (and note that it’s not mandatory for VMUG membership), you can have more benefits by subscribing to the VMUG Advantage, that is an interesting way to stay on top of your technical skills with discounts on training, certifications, attendance at VMworld and on product licenses.

Reading Time: 7 minutesTo implement some encryption solutions (like VM encryption, backup encryption, storage encryption) you need to manage symmetric keys in a secure way. Key management has always been solved with proprietary solutions. Each vendor have offered in the past their own key management server/client combination, but as the complexity of datacenters increased, this designed has shown its limits. If you have multiple components, all in need of security keys, why you would need to run multiple key management solutions? But in order to have a common solution, you first would need a protocol to let all […]

Reading Time: 2 minutesSome years ago, I’ve published a post about the Hyperconverged infrastructure market share (2018)… but what about now? How HCI has grow? HCI has become a hot topic with several vendors that aim to be a leader in this area, or with several “magic quadrants” that try to define who is in.

Reading Time: 3 minutesPiù di dieci anni fa avevo scritto un posto su come sia meglio evitare i dischi dinamici di Windows (specialmente Windows Server)… ma a quanto pare c’è ancora chi si ostina ad usarli pensado siano utili e non pensado alle conseguenze. Microsoft Windows Dynamic Disks (chiamati anche Dynamic Volumes) sono un livello di astrazione (introdotto in Windows 2000) sulle partizioni (simile a LVM in ambiente Linux/Unix) per disaccoppiare i volumi (con i relativi dati NTFS) dalle partizioni del disco e avere un maggiore flessibilità, come l’estensione a caldo di un volume semplicemente aggiungendo nuove partizioni […]
