When you create a new virtual machine in VMware vSphere (or also on a standalone ESXi) a default virtual hardware is choosed, according with the version of the ESXi. You can choose your own (with the custom wizard) or upgrade later, but note that the virtual hardware upgrade from the vSphere Client will always upgrade to the latest version supported by the host. Otherwise the upgrade from the vSphere Web Client you can choose the different version of virtual hardware.

VMware has announced the End of Availability (“EoA”) of all versions of vSphere Enterprise, vSphere with Operations Management Standard and vSphere with Operations Management Enterprise. The EoA effective date is June 30, 2016. After these dates, you will only be able to purchase these products on an exception basis VMware has also announced price changes for vSphere with Operations Management Enterprise Plus from $4,245 per CPU to $4,395 per CPU, and VMware vCenter Server™ Standard from $4,995 per instance to $5,995 per instance (referenced pricing represents suggested MSRP for the U.S., in USD; regional prices […]

VMware is unveiling the new VMware vCloud Suite 7 and vRealize Suite 7 that define the entire Cloud Management Platform (CMP). VMware delivers an Enterprise-ready cloud management platform (CMP) that supports two IT Outcomes.  The CMP speeds up IT service delivery, improves IT efficiency, and optimizes IT operations and capital spending. In this new release, VMware is further enhancing the cloud management platform to better support specific use cases our customers are addressing in their cloud management journeys.

As announced some months ago, the new Virtual SAN (VSAN 6.2) will add new data services making this solution more rich that before. Version 6.1 was announced during the last VMworld editions with some interesting features, including a ROBO scenario. But was still limited in data service: better snapshot technologies, better VMFS, but still some limits and no deduplication, no compression, no erasure coding at all.

End User Computing (EUC) is a difficult and challenge market: each year there is a promise to solve and manage it with MDM or VDI solutions (wasn’t the 201x the year of VDI?). But enterprise needs conflict with users and consumer needs. Enterprise needs security (at each levels) and users need simplicity (and usability) otherwise the solution is not adopted or accepted. VMware has address the EUC market in those year (see for example this 2012 report) with different products (like Horizon View, Mirage, AirWatch, …) and still consider it as a major pilar of […]

VMware vSphere 6.0 has got some issues, like the several related to CBT and data protection, during the first years of its life. Mostly is finally resolved, but you may still have strange issuesespecially during the upgrade procedure (most when you start from a vSphere 5.1 version). I notice, after an upgrade, also a strange behavior with vMotion where live VM migration fails with this error: A general system error occurred: PBM error occurred during PreMigrateCheckCallback: No connection could be made because the target machine actively refused it.

As you probably know VMware vSphere 6.0 had a critical issue con its Change Block Tracking (CBT) implementation that can impact all incremental backup with “VMware native” backup program (all agent-less implementation using the VMware VDAP API). This issue occurs due to an issue with CBT in the disklib area, this causes the change tracking information of I/Os that occur during snapshot consolidation to be lost. The main backup payload data is never lost and it is always written to the backend device. However, the corresponding change tracking information entries which occur during the consolidation task are missed. […]

Photon Platform is a new infrastructure stack optimized for containers and cloud-native apps. It’s built to be used in API-driven, multi-tenant, high scalable, greenfield environments. You can run on it Docker, Mesos, Cloud Foundry or Kubernetes in a secure environment. The Photon Platform tt’s composed of two main components: Photon Machine, a lightweight “microvisor” based on ESX with Photon OS built-in.With Photon Machine, you can deploy Docker containers on a VMware hypervisor that includes built-in, mature, and enterprise-ready capabilities. Photon Controller, a distributed and multi-tenant, API-driven control plane optimized for scale, churn and high-availability. It manages […]

Changed Block Tracking (CBT) is a VMware feature introduced in vSphere 4.0 in order to implement native incremental backup at source level. VMware VDAP uses this technology and so all backup and recovery software designed for VMware use it for speed the backup. But last week a critical issue has been discovered on all vSphere 6  version (included the lates Update 1a) where Changed Block Tracking (CBT) data on ESXi 6 cannot be trusted.

As usually in the past years (see for example the 2014), the European VMworld is used to announce new software releases in the VMware Cloud Management Platform. In VMware strategy, Cloud Management is the control plane for the Software-Defined Data Center and the Hybrid Cloud and, of course, is one strategical aspect for both pillars. In the past year there is a shift from multiple products, multiple suites, to a unified platform:

Mastering VMware vSphere Storage book is intented for users who already have some experience with the VMware vSphere platform and want to learn and design VMware vSphere storage solutions and how to troubleshoot vSphere storage issues. The main purpose of this book is monitor and optimize the storage capabilities of your vSphere environment.
