Now that the PSOD on vSphere 6.5 and 10 Gbps NICs issue is finally solved seems that vSphere 6.5 critical bugs are closed, but it’s not totally true. During an upgrade from a vSphere 6.0, I’ve found a really strange iSCSI storage issues where all the VMs on the iSCSI datastore were so slow to become un-usable. First I was thinking about drivers or firmware, in the hosts and in the NIC (1 Gbps) or the firmware on the storage.

On October 2017, I wrote a post about a possible issue with vSphere 6.5 and 10 Gbps NICs (mostly standard on new deployment). The final result was a PSOD (Purple Screen Of the Death) and no solution was available (yet). VMware KB 2151749 describe this issue as related to possible upgrade at vSphere 6.5. But other customers have report the issue also on new deployment. Veeam, one of the first vendor to found this issues (from their customers), reports that the issues is due to network-intensive activities such as backup over NBD or vMotion randomly triggering one.

In the spirit of the holiday season, Veeam is offering 6 lucky winners a fully paid trip to a VeeamON 2018 event organized in their respective region! This opportunity will close on 31 December 2017… so just few days left!

As written in a previous post, some months ago, I’ve started a huge personal project that consumes all my spare free time. This project was a new book on VMware vSphere 6.5, really ambitious considering that will be a “Mastering” book, but the title and part of the content were not negotiable with the editor. Finally, the book Mastering VMware vSphere 6.5 is done and it’s now available on Packt site (and in the future also on Amazon).

Nutanix has announced the new list of Nutanix Tech Champions (NTC) 2018. NTC is a community award, started on 2014, similar to others programs like VMware vExpert, Microsoft MVP, Cisco Champions, EMC Elect, … rewarding members of the community on their efforts in sharing their knowledge and enabling fellow community members. The Nutanix Technology Champion program spans the globe and is comprised of IT professionals from every cloud, application group, and technology. They are committed to news ways of thinking that will power the next generation of enterprise computing.

Veeam has just released a lot of new versions of its products, providing the strategic Availability and data management platform for customers of any size. Veeam Availability Platform supports any workload — virtual, physical or cloud — in multi‑cloud environments comprised of private, public, Software as a Service (SaaS) or managed clouds. For some products is just an updated version, but Veeam has started (with VBR 9.5) a continuous integration of new features (and some anticipations of new features of v10), so this list of new products it’s very interesting:

Tintri has an interesting VM-aware All-Flash storage platform for virtualization and cloud environments. There are both All-Flash and Hybrid-Flash products, but the most interesting aspects are the VM-aware capability, the analytics data, and the scaling model. The arrays are similar to other two-controllers arrays, with a scale-up (or scale-in) model. But some years ago Tintri unveils its scale-out storage model where was possible grow your storage base in a simple way.

For this Monday, Packt is selling each book and each video for just 5 dollars! Over 5000 resources where you can choose. Strange but in Euro it’s more than 5 (it’s 5,24€) but remains anywhere a big deal for a very few weeks! For all VMware books use this search:

One year ago, VMware has started the bifurcation of VMware Tools for Legacy and Current Guests using of two separate delivery vehicles: VMware Tools 10.1 is available for OEM-supported guest OSs only VMware Tools 10.0.12 was for the guests OS that have fallen out of support by their respective vendors are offered “frozen”. The frozen VMware Tools will not receive feature enhancements going forward.

vOneCloud is an OpenNebula distribution optimized to work on existing VMware vCenter deployments to provide full cloud features. It deploys an enterprise-ready OpenNebula cloud just in a few minutes where the infrastructure is managed by already familiar VMware tools, such as vSphere and vCenter Operations Manager, and the provisioning, elasticity and multi-tenancy cloud features are offered by OpenNebula.

VMUG Virtual Events are the single most impactful tech events for professionals utilizing VMware products and solutions. Created by VMware users for VMware users, these FREE day-long events are geared to empower you through education, training, and collaboration, all with the goal of impacting your projects and your career. Next VMUG Virtual event will be the 13th of December 2017:

This is an article realized for StarWind blog and focused on the design and implementation of stretched cluster. A stretched cluster, sometimes called metro-cluster, is a deployment model in which two or more host servers are part of the same logical cluster but are located in separate geographical locations, usually two sites. In order to be in the same cluster, the shared storage must be reachable in both sites. Stretched cluster, usually, are used and provided high availability (HA) and load balancing features and capabilities and build active-active sites.

VMware vSAN should manage better VM snapshots compared with traditional storage and VMFS datastores. The reason is the new (v2) on-disk format in VSAN 6.0 and the new filesystem that is used: VirstoFS. VirstoFS is the first implementation of technology that was acquired when VMware bought a company called Virsto a number of years ago. Also there is a new sparse format called vsanSparse. These replace the traditional vmfsSparse format (redo logs).

In the VMware ESXi 6.x partitions layout, usually there is a partition called “scratch” that hosts the log, the updates and other temporally files. Scratch space is configured automatically during installation or first boot of an ESXi host, and is not required to be manually configured. If you install ESXi on a local hardware disks (or also if you are using a remote LUN in “boot from SAN” mode), this partition is build during the installation phase (it’s 4 GB Fat16 partition created on the target device during installation, if there is sufficient space).
