Reading Time: 2 minutesVMware 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).
Reading Time: 3 minutesIn the VMware ESXi 6.x partitions layout, usually, there is a partition called “scratch” that hosts the log, the updates, and other temporal 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 disk (or also if you are using a remote LUN in “boot from SAN” mode), this partition is built during the installation phase (it’s 4 GB Fat16 partition created on the target device during installation, if there is sufficient space). If you install ESXi on a USB connected mass storage (like the SD cards), then this partition is usually skipped and the ramdisk will be used instead.
Reading Time: 2 minutesAfter the release of VMware NSX-T v2.0 only three months ago, now VMware has released the new version: NSX-T v2.1, that will enable advanced networking and security across these emerging app architectures, just as it does for traditional 3-tier apps.
More specifically, NSX-T 2.1 will serve as the networking and security platform for the recently announced VMware Pivotal Container Service (PKS), a Kubernetes solution jointly developed by VMware and Pivotal in collaboration with Google. NSX-T 2.1 will also introduce integration with the latest 2.0 release of Pivotal Cloud Foundry (PCF), serving as the networking and security engine behind PCF. In these environments, NSX-T will provide Layer 3 container networking and advanced networking services such as load balancing, micro-segmentation, and more.
Reading Time: 3 minutesVMware Cloud Foundation is VMware’s unified SDDC platform for the hybrid cloud and it’s based on VMware’s compute, storage, and network virtualization technologies to deliver a native integrated software stack that can be used on-premises for private cloud deployment or run as a service from the public cloud with consistent and simple operations.
VMware has announced the upcoming release of VMware Cloud Foundation 2.3. This new release comes with many new capabilities to help further simplify the tasks of deploying, operating and maintaining a VMware based hybrid cloud.
Reading Time: 2 minutesOn December, 4th 2017, I’ve been invited at the VMUG CZ Meeting and it was a nice opportunity to meet some friends (and know new friends).
It was also the opportunity to bring my experience with stretched clusters, mainly in VMware environment, in a presentation that I’ve titled “The dark side of stretched cluster“, in order to pointing not only at the pro of this configuration, but also at the possible cons.

Reading Time: < 1 minuteVMware has announced a preview of VMware Hybrid Cloud Extension service as an add-on service to VMware Cloud on AWS. (like the Site Recovery add-on).
Hybrid Cloud Extension service will enable customers to adopt the latest VMware Cloud on AWS offers, without the need to refactor applications and redo security and compliance architectures. Hybrid Cloud Extension service will provide large scale application migration and mobility between legacy VMware vSphere environments (vSphere 5.0+) and VMware Cloud on AWS to support this use case.
