Reading Time: 6 minutes VMware vCloud Air is the public cloud offer by VMware (formally known as vCloud Hybrid Service) built on the foundation of vSphere and compatible with your on-premises VMware’s based data center. Actually it included several different services: infrastructure, disaster recovery, and various applications as service. For the IaaS services there are: Dedicated Cloud, Virtual Private Cloud, Virtual Private Cloud OnDemand. For the availability services there are: Disaster Recovery and Data Protection. I’m spending some time by testing the Virtual Private Cloud OnDemand service, with a limited time $500 service credit offer. If you are also interested […]

Reading Time: 3 minutes After an upgrade to VMware vSphere 5.5 on a Dell PowerEdge R710, I’ve got strange occasion issues, where the hosts got completly disconnected from vCenter (with the ESXi/ESX host’s status as Not Responding or Disconnected in vCenter Server) and there was no way to reconnect, also after restarting the management services. Locking in the ESXi console those kind of errors where notable: Bootbank cannot be found at path ‘/bootbank’. The only temporally solution was power-off the VMs and restart the host. But the issue can randomly came back.

Reading Time: 3 minutes In previous posts (see ESXi – Partitions layout of system disk and ESXi – More on partitions) I’ve described how are handles the partitions table on the destination installation media of ESXi 5.x (both in the case of a hard disk or a SD/USB disk). With the new ESXi 6.0 the partition tables is similar in the case of a 1 or 2 GB destination device (like a previous SD media), but has some changes in the case of larger devices. Core partitions remain the same with standard size:

Reading Time: 5 minutes Some days ago I was invited to as a delegate at the first edition of Data Field Day (#DFD1) event, scheduled in May 13–15, 2015 in California (Silicon Valley and San Francisco). Data Field Day event purpose was to cover different topics from others Technical Field Day events: from big data to analytics to hyperscale architecture and cloud security, and all waves of innovations that are transforming the IT. A new format for some growing trends, including micro-services, mobile and the Internet-connected world. But if you have seens some of the presentation video you may have some doubts if […]

Reading Time: 2 minutes VMware EVO:RAIL represent the first Hyper-Converged Infrastructure offerings from VMware, announced in VMworld 2014 and available from the second half of 2014, and based (on the software part) on vSphere 5.5 and VSAN 1.0. Now there is a new software release of VMware EVO:RAIL which includes also support for the VMware EVO:RAIL vSphere Loyalty Program. One of the most notable improvements is that the scale of the hyper-converged infrastructure appliances are now doubled: from beyond the initial four appliances in a cluster and 16 nodes overall to eight appliances in a cluster and 32 nodes […]

Reading Time: 3 minutes Due to the changes in the new vCenter Server 6.0 architecture, the SSO has now been incorporated in the new VMware Platform Services Controller “role”. But the concepts of a global SSO accounts still exist and remain important to manage the infrastructure (and more important during installation and upgrade). If you forget the SSO admin password you can have some trouble. I’ve already wrote on how reset the VMware SSO password in the vSphere 5.1 and 5.5 versions and the procedure remain almost the same also in the 6.0 version.

Reading Time: 2 minutes In previous post we have already see how add custom drivers to an ESXi installation ISO and how use ImageBuilder to make custom ESXi ISO, but in other cases you may need to define some custom settings during the installation or add custom vib files. Booting from CD is not the only way, but custom ISO could be used also for boot from USB or for boot from virtual devices (like the iDRAC or ILOE). In case you need to build custom ISO with custom option this post could help you: How to Create Bootable ESXi […]

Reading Time: 2 minutes Maxta, a storage company that provide hyper-converged solutions, announced MxInsight and MxCloudConnect, confirming a recent trend both in the analytics applied to the storage and also in the cloud based management solutions available as SaaS. Other vendors (not only in the storage area, see for example Meraki in the network area with a real unique management solution) are moving in one or both of this directions. Of course those aspects are not related to the core technology (for Maxta the hyper-converged storage), but on the services that you can have in order to simplify the IT management.

Reading Time: 2 minutes Compatibility remain one of major reason for wait before a major upgrade, but now several backup products are compatible with vSphere 6.0 (see Backup products and vSphere 6.0 compatibility – Updated). Same for several other 3rd part software. But in the backup space there are still some issues that may limiting the choice of running (yet) vSphere 6.0 in production environments. As written in VMware vSphere 6.0 – Upgrade or not upgrade post one was related in CBT in ESXi 6.0 that can impact your environment also if your backup program will already support vSphere […]

Reading Time: 6 minutes As written in a previous post (VMware certification roadmap v6) there are already several v6 exams (and the VCP level is almost completed, although still with some beta exams for the DCV path). VCP level has also changed (Are you ready for new VMware’s certifications?) with a “foundations exam” common for all paths and then specific VCP exams. The VCP6-DCV has different upgrade paths, but if you are already a VCP-DCV (not expired) the simple way is just took the VMware Certified Professional 6 – Data Center Virtualization Delta Beta Exam. Those beta exams (for […]
