Reading Time: < 1 minuteStarting with ESXi 7.0 the partions layout has totally changed, compared to previous versions. And also the disk requirements have changed… you cannot install anymore on a very small disk (less than 4 GB) and the minimum required size is 32 GB. A big change, considering that before was possible install ESXi with less than 1 GB!
Reading Time: 3 minutesIn VMware ESXi, I/O filters can gain direct access to the virtual machine I/O path. The I/O filters are independent of the storage topology and is possible to enable the I/O filter for an individual virtual disk level. VMware offers certain categories of I/O filters, in addition, third-party vendors can create the I/O filters. Typically, they are distributed as packages that provide an installer to deploy the filter components on vCenter Server and ESXi host clusters.
Reading Time: 2 minutesAfter VMware acquisition, Broadcom has start to change VMware’s licensing tring to normalize and simplify it, but also tring to maximize the possible revenew. This not not so good for all customers. Also some offering has been dismissed, like the Free vSphere Hypervisor or the basic VMware vSphere Essential bundle.

Reading Time: 5 minutesSystem virtualization remain the foundation of several datacenter infrastructures, although somebody thinkgs that virtualization is not cool anymore. For the on-prem deployment VMware (by Broadcom) vSphere is still the main solution with a large adoption (over 60% according with several analyst), but after Broadcom acquisition and all the changes in the licensing model and licensing price, some customers are looking for some alternatives.
Reading Time: 2 minutesVMware vSphere 8.0.3 introduces several new features and also a new snapshot management. One of the issues of VM snapshots is that people forget to delete them: according to VMware snapshot management recommended practices you shoul NOT keep snapshots for more than 3 days (I suggest to don’t keep them for more than one day, because usually you have backups as other possible restore points).
Reading Time: 4 minutesIPv4 (Internet Protocol version 4) is a widely used protocol for network communication and is a core component of the TCP/IP stack. But it has some limits, one is the limit in terms of available addresses, expecially if we are talking about public IP. IPv6 (Internet Protocol version 6) was design to resolve all the limitation of IPv4. IPv6 is designated by the Internet Engineering Task Force (IETF) as the successor to IPv4 providing the following benefits:
Reading Time: 2 minutesLike every hardware and software components, before apply a VMware vSphere upgrade or update you have to check all compatibility aspects. One is related to the backup software that can be critical because you may loose the capability to perform backup and/or restore. Of course this apply also to “minor” update, like vSphere 8.0U3. For Veeam Backup & Replication there is a specific Veeam KB (KB 2443) that provides information about compatibility between VMware vSphere and Veeam Backup & Replication. And finally, some weeks after ESXi 8.0.3 become GA, there is an official support for vSphere […]
