Reading Time: 1 minute The last week I’ve realized a new article for the StarWind blog focused on the different types of storage controllers in VMware vSphere (see Storage Controllers in VMware vSphere). To access block-based devices (like virtual disks, CD/DVD-ROM), but also generic SCSI devices, a virtual machine uses storage controllers, which at least one is added by default when you create the virtual machine and the type of it depends by the type of guest OS that you have chosen. You can make several change changes while you are in the creation wizard.

Reading Time: 3 minutes This year has started with the revelation of the Meltdown and Spectre vulnerabilities afftecting most of the (old and new) processors including Intel, AMD and ARM… but also others. In little less than one year we are still far from the solution because there are some patches, but those patches have serious performance impacts and sometimes are those patches require more and more time to become effective (instead of causing new issues).

Reading Time: 2 minutes Announced during the last OpenIO Summit 2018, the new release OpenIO SDS 18.10 has been announced. OpenIO SDS transforms commodity servers into large object storage and compute pools. They build a scalable solution designed to grow as you need, that can handle from terabytes to petabytes.

Usually OpenIO SDS has a 6-month release cycle and now following the OpenIO SDS 18.04 released in August 2018, this new version version of SDS is now available with a […]

Reading Time: 4 minutes Now 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 minutes Remote 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.

Reading Time: 5 minutes You can easily move hard drives from one QNAP NAS to another for seamless system migration while retaining all existing data. But this usually works if you are moving from an old to a new model. For example, users can migrate their QNAP NAS to another Turbo NAS model with all the data and configuration retained by simply installing all the hard drives of the original (source) NAS on the new (destination) NAS according to its original hard drive order and restart the NAS. What it’s nice is that this procedure can also migrate between […]
