Now that both Microsoft and VMware have officially announced the new released of their virtualization products it’s possible to make some kind of comparison between Hyper-V available on Windows Server 2019 and vSphere 6.7 (like I’ve done some years ago with the Microsoft Hyper-V 2016 vs. VMware vSphere 6.5 article).

Comparing two different product is not so easy, also if they are released closed one each other (at least in the same year). You need to found some homogenous aspects to make the comparison, at least at the technical level (but as written, it’s not so much important now where the technology gap is really reduced). For numbers could be really easy, but numbers are not enough: for example memory management it’s still really different (VMware implement different technologies, Hyper-V only Dynamic Memory, only on some OSes)… so it’s not the same what you can do with the same amount of memory.

VMware certification paths are quite clear with well defined technology paths (DCV, EUC, NV, Cloud) and different levels (VCP, VCAP, VCDX).

All certifications require at least one proctored exam (some may require two different exams). The names of all exams and certifications will change using a “year” notation, but the concept remain the same.

But there are also other type of exam, non proctored and just on-line version. One example are the Foundation exams.

La notizia delle ultime ore è veramente grossa: IBM è in procinto di acquistare Red Hat per 34 miliardi di dollari ($190 per share in cash). La chiusura dell’operazione è prevista per la seconda metà del 2019.

Partner da oltre 17 anni, IBM e Red Hat hanno gettato le basi delle community aperte che supportano soluzioni IT innovative e fornito infrastrutture IT che consentono alle aziende di migrare da architetture limitate a datacenter moderni.

Questa operazione è una delle più grandi acquisizione in ambito software di sempre ed acquisisce ancora più valore considerando che Red Hat è uno dei principali espondenti non solo del mondo Linux, ma del mondo Open Source in generale.

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: 2 minutesDi recente, durante il VMworld US 2018, VMware ha celebrato i suoi 20 anni di storia che hanno segnato una rivoluzione nel mondo dell’IT, grazie alla virtualizzazione per ambienti x86.

Ma in realtà esiste un’altra soluzione di virtualizzazione su x86 che anch’essa ha tanta storia e che questo mese compie i suoi 15 anni: Xen Project, con il supporto a guest Linux 2.4.22.

Nel lontano ottobre 2003, Ian Pratt (il fondatore del Xen Project) annuncia la prima release stabile del Xen virtual machine monitor per x86!

The job was starting correctly, VMs have been discoverted, but when the backup start to copy the VMDK the job failed with a “VDDK async operation error 14009” message.
