Quick Boot is a vSphere feature that speeds up the upgrade process of an ESXi server.  A regular reboot involves a full power cycle that requires firmware and device initialization.  Quick Boot optimizes the reboot path to avoid this, saving considerable time from the upgrade process.

Quick Boot of an ESXi host is a setting that allows VMWare Update Manager (VUM) to optimize the remediation time of hosts that undergo patch and upgrade operations. If the Quick Boot feature is enabled, Update Manager skips the hardware reboot (the BIOS or UEFI firmware reboot).

As a result, the time spent by ESXi host in Maintenance Mode shortens and the risk of failures during remediation is minimized.

Reading Time: 6 minutesFound a proper way to protect your public cloud services and your data in a public cloud is becoming more and more important, to achieve a desired retention limit, but also to have more control on the data and the restorability of them.

One interesting case is the messaging and collaboration services, like Office365 and G Suite.

Reading Time: 4 minutesRecently, during VMworld US 2018, VMware has celebrated the 20 years of the company.

But there is another virtualization project that has a lot of history like VMware: the Xen Project and this October marks our 15th anniversary.

On October 2003, Ian Pratt (founder of the Xen Project) announces the first stable release of the Xen virtual machine monitor for x86, and port of Linux 2.4.22 as a guest OS.

It was one of the most popular open source hypervisors and amasses more than 10 million users; but now there is a clear rise of KVM and also Amazon AWS has announced to adopt a home-brewed KVM as new hypervisor instead of the home-brewed Xen.

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.

One of the most read post remain how to Purge old data from a vCenter Server DB, but was written on 17 January 2014 and related to vSphere 5.1 version with the vCenter Server based on Windows Server.

Thinks are changed in those years, but problems could remain the same also with VCSA 6.x.

You can have similar issue also with the VMware vCenter Server database, considering that it can continuous grow due to the statistics and also due to the events/tasks. In really small system a simple solution could be re-install a fresh version of vCenter Server (maybe during an upgrade) and re-create all the configuration stored only in the vCenter Server database. But in several cases this approach is not realistic.
