VMware vSphere 6.5 Host Deep Dive – Free ebook

VMware
The VMware vSphere 6.5 Host Resources Deep Dive is a guide to building consistent high-performing ESXi hosts. A book that people can’t put down. Written for administrators, architects, consultants, aspiring VCDX-es and people eager to learn more about the elements that control the behaviour of CPU, memory, storage and network resources. This book shows that we can fundamentally and materially improve the systems we’re building. We can make the currently running ones consistently faster by deeply understanding and optimising our systems. The reality is that specifics of the infrastructure matter. Details matter. Especially for distributed platforms which abstract resource layers, such as NSX and vSAN. Knowing your systems inside and out is the only way to be sure you’ve properly handled those details. It’s about having a passion for these…

VMware Labs – DRS Dump Insight

VMware
DRS Dump Insight is a service portal where users can upload drmdump files and it provides a summary of the DRS run, with a breakup of all the possible moves along with the changes in ESX hosts resource consumption before and after DRS run. Users can get answers to questions like: Why did DRS make a certain recommendation? Why is DRS not making any recommendations to balance my cluster? What recommendations did DRS drop due to cost/benefit analysis? Can I get all the recommendations made by DRS? Once the drmdump file is uploaded, the portal provides a summary of all the possible vMotion choices DRS went through before coming up with the final recommendations. The portal also enables users to do What-If analysis on their DRS clusters with options like:…

Nested Virtualization in Azure

Microsoft
Today Microsoft announced that you can now enable nested virtualisation using the Dv3 and Ev3 VM sizes. Microsoft will continue to expand support to more VM sizes in the coming months. For software and hardware prerequisites, configuration steps and limitations for nested virtualisation please see the document here. In this blog Microsoft discuss a couple of interesting use cases and provide a short video demo for enabling a nested VM. Now not only you can create a Hyper-V container with Docker (see instructions here), but also by running nested virtualisation, you can create a VM inside a VM. Such nested environment provides great flexibility in supporting your needs in various areas such as development, testing, customer training, demo, etc. For example, suppose you have a testing team using Hyper-V hosts on-prem today.…

Azure VPN Gateways New SKU

Microsoft
A VPN gateway is a type of virtual network gateway that sends encrypted traffic across a public connection to an on-premises location. You can also use VPN gateways to send encrypted traffic between Azure virtual networks over the Microsoft network.  To send encrypted network traffic between your Azure virtual network and your on-premises site, you must create a VPN gateway for your virtual network. Microsoft have recently released a new set of gateway SKU's which provides an increase in aggregate throughput, you can see the increase in throughput and new SKU below. If you haven't got the luxury of Express Route then you'll be jumping for joy knowing that you can go beyond the old restriction of 200MB (High Performance SKU), but hang on for a second there are some…

Azure ASR for IaaS virtual machines

Microsoft
Microsoft this week announced the public preview of disaster recovery for Azure IaaS virtual machines (VMs) using Azure Site Recovery (ASR). You can now easily replicate and protect IaaS based applications running on Azure to a different Azure region of your choice within a geographical cluster without deploying any additional infrastructure components or software appliances in your subscription. This new capability, along with Azure Backup for IaaS virtual machines, allows you to create a comprehensive business continuity and disaster recovery strategy for all your IaaS based applications running on Azure. As you move production applications to the cloud, Azure natively provides you the high availability and reliability that your mission critical workloads need. However, compliance requirements such as ISO 27001 still require that you have a provable disaster recovery solution…

Azure IaaS Virtual Machines Temporary Drives

Microsoft
I’ve seen many posts on forums asking for more detail on the temporary disks assigned to Azure IaaS Windows and Linux VMs so here is a quick post explaining what they are. When you create a VM either in the portal or command line utilities (i.e. PowerShell) you automatically receive an additional drive or mount point which is available for you to use at no additional cost for storage or transactions.  The primarily use case is to provide faster storage (IOPS and Latency) but although this sounds great it isn’t to be used for any data that you wish to keep. You typically store temporary data on these drives like Windows page files and Linux Swap files or even SQL TempDBs.  As you can see from the images below it…
