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).

VMware 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.

VMware 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.

During AWS re:Invent 2017 event, VMware has announced a new service based on VMware Cloud on AWS. The new service brings VMware enterprise-class Software-Defined Data Center (SDDC) Disaster Recovery as a Service to the AWS Cloud. VMware Site Recovery™, a robust disaster recovery as a service (DRaaS) offering that protects workloads between on-premises datacenters and VMware Cloud on AWS, as well as between different instances of VMware Cloud on AWS.

Microsoft has announced the preview of VMware virtualization on Azure, a bare-metal solution that runs the full VMware stack on Azure hardware, co-located with other Azure services. General availability is expected in the coming year. This new service will be delivered in partnership with premier VMware-certified partners, and not directly with VMware (like, for example, VMware Cloud on AWS).

VMware has recently released the new verion of vRealize Network Insight (vRNI) 3.6 that adds key capabilities that enhance network and security visibility in customers’ SDDC and AWS environments, and that enable customers to confidently deploy, manage and scale their VMware NSX deployments. VMware vRealize Network Insight delivers intelligent operations for software-defined networking and security and helps customers build an optimized, highly-available and secure network infrastructure across multi-cloud environments. Also it can accelerates micro-segmentation planning and deployment, enables visibility across virtual and physical networks and provides operational views to manage and scale VMware NSX deployments.

VMware Cloud on AWS brings enterprise-class SDDC software to the AWS Cloud, delivered as an on-demand service. VMware Cloud on AWS is a vSphere-based cloud service offered directly by VMware, but with resources hosted on AWS. Announced during VMworld 2016, finally was available during VMworld 2017 (actually only available in the US regions Virginia and Oregon).

Seems that there are still some issues with vSphere 6.5, with a possible PSOD (Purple Screen Of the Death) after upgrade to 6.5U1 on ESXi hosts using 10 Gbps NICs. The VMware KB 2151749 describe this issue and explains that this occurs because Netqueue commit phase abruptly stop due to the failure of hardware activation of a Rx queue. As a result, Internal data-structure of the Netqueue layer’s could go out of sync with the device and cause PSOD.

The latest Adobe Flash update (note that the update has been included also in Microsoft Update) with v 27.0.0.170 make the vSphere Web Client no more usable with all browsers. With Chrome and Firefox you will recognize that the Flash plugin hangs, in Internet Explorer you will have a simple generic error and the browser that will close.

If you are going to using vSphere Replication you will notice, after the deployment of the two virtual appliances a continuous (also each minute) logging of installation activities on all the ESXi hosts in the protected cluster. This is quite annoying but also is going to fill up your log both in the ESXi hosts and in the vCenter database (are all tasks visible in the the vCenter console).

One of the big advantages of the virtual appliance version of VMware vCenter (vCSA) is the ability to update both the OS components and the VMware parts with a simple menu. Just use the administrative UI available at https://vCSA_IP:5480 and login with user root and the password that you have choose during the deployment.
