Comments off

Reading Time: 4 minutesNow that Network Virtualization and Software Defined Network are becoming mainstream, there is a new trend in networking: Software-Defined WAN (SD-WAN). What is SD-WAN? SD-WAN is best defined as traffic monitoring and management from physical devices to the application itself, capitalizing on flexibility and agility. This intelligent routing is abstracted into a virtual overlay, enabling a secured pooling of both private and public connections allowing for automation, centralized network control and real-time management across multiple links.

Reading Time: 2 minutesRemote Direct Memory Access (RDMA) is an interesting way to improve network connections and bandwith by providing a direct memory access from the memory of one system  into that of another. Compared to the full TCP/IP stack, RDMA can be managed without involving either one’s operating system (OS) and this means saving host resources and speed-up the communication. RDMA permits high-throughput and low-latencynetworking, but more important is becoming a common feature on some network card, and also supported by different OSes and hypervisors.

Problemi con il driver vmxnet nelle VMware Tools 10.3.0

8 Settembre 2018
Comments off

Reading Time: 3 minutesTre anni fa, VMware ha annunciato l’intenzione di gestire le VMware Tools in modalità standalone, ossia con un rilascio indipendente da quello dei prodotti di virtualizzazione e con un proprio ciclo di vita e sistema di versioning.

Sembra bello, ma sicuramente siamo ancora in una fase confusionale, visto che esistono sia le VMware Tools standalone, sia quelle incluse nei prodotti di virtualizzazione.
