There is a new PDF called What’s New in vSphere 6 – Performance, since a couple of days at VMware which compares the performance of vSphere 5.5 and vSphere 6.0. vSphere performance improvements since the v 5.5 are one of the core questions from users after the “What’s New in vSphere 6.0” question. The compare […] Read the full post vSphere Performance Improvements – New PDF at ESX Virtualization.
In this post, I’m going to cover the installation of the Storage Replication Adapter (SRA) for Site Recovery Manager. When using array-based replication, this is an absolute must piece of software that the vendor providers as it enables SRM to integrate and work the specific array. The SRA needs to be installed into each SRM […] The post SRM with VMAX 20K Part VII: Installation of Storage Replication Adapters appeared first on vRyan.co.uk – Virtualization Blog.
Yesterday VMware released the vRealize Production Test which is an add-on tool to the vRealize Suite that you can use to monitor the production health of your vRealize Suite deployment from the initial deployment to the operational phase. By using vRealize Production Test, you can run a suite of tests from the command line using the API of the vRealize Suite components to assess and report on the health of those components. The vRealize Suite is a platform of data collection intensive applications used to govern and manage virtual and cloud infrastructure. In a production environment outages can range from loss of connectivity to one vCenter, to a complete inability to provision or monitor the environment. vRealize Production Test is a…Read More
Ealier this week I’ve been configuring a new VSAN cluster. The old configuration was using hardware that wasn’t complying with the VMware vSAN HCL. We ordered new raid controllers and HDD’s and reused the SSD disks, as those where compliant with the HCL. Adding and configuring the new hardware went well and ESXi was installed without a problem. After doing some network configurations on the hosts it was time to turn on VSAN. And that is where I ran into an issue. The moment I turned on VSAN (manual mode) each host created a disk group containing the SSD’s present in the host. Each disk group however was showing only absent HDD’s. Seeing as I was using SSD’s from a previous configuration I wasn’t that suprised and tried removing the disk…Read More
An existing vShield environment can be upgraded to a full NSX environment, as described in my VCIX post “Upgrade VMware NSX Components”. All vShield components can be upgraded, except for one; vShield Data Security. The documentation states: NSX Data Security does not support a direct upgrade. You must uninstall the current Data Security software before upgrading to NSX Manager. After NSX Manager is upgraded, you can install NSX Data Security version 6.0. If you upgraded to NSX Manager without uninstalling Data Security, you must do so using a REST call. A few days ago, someone came to me with an environment where this exact thing happened. They had upgraded to NSX for all its goodness, but had not removed Data Security and could not…Read More
VMware vSphere Metro Storage Cluster (vMSC) is not a product but a certified configuration where a vSphere cluster spans geographical locations. This could be spread across a campus, metropolitan area or a larger area up to 200 km apart. vMSC … Continue reading →
Cody’s article on UNMAP changes for vSphere 6 got me thinking about how this plays out in the VDI context.I’ll explore a bit desktops deployed both as linked clones with and without se-sparse disks as well as full desktops with thin provisioned disks. Before we get started I’m first goingto turn on the advanced option […] The post UNMAP Observations w/Horizon Desktops appeared first on JediMT.
I think we can all agree that ol’ Al Einstein was a pretty smart dude right? Especially when it came to his thoughts around insanity and the “doing the same thing over and over and expecting different results” spiel. The thing is Al’s not here anymore and while yeah, he was a wise one, he
by Rich Bourdeau VMware NSX and vRealize Automation deliver secure, scalable, and high performing applications on-demand Applications need much more than appropriately sized virtual machines. They also need accurately configured network connectivity, security, availability, scale, and performance. In order to deliver these capabilities to your applications you will need to automate more than just assigning IP […]
Who loves virtual Performance? Who wants to learn more about it? Everybody of course! I’m very excited about this year’s Extreme Performance Series mini-track being hosted at VMworld San Francisco and Barcelona. These sessions are created and presented by VMware’s best and most distinguished performance engineers, architects and gurus. I’ve tried to provide my personal […]

VMware NSX is the network virtualization and security platform that emerged from VMware after they acquired Nicira in 2012. This acquisition launched VMware into the software-defined networking (SDN) and network functions virtualization (NFV) world. The solution de-couples the network functions from the physical devices, in a way that is analogous to de-coupling virtual servers (VMs) from physical servers. In order to de-couple the new virtual network from the traditional physical network, NSX natively re-creates the traditional network constructs in virtual space — these constructs include ports, switches, routers, firewalls, etc. In the past, everyone knew what these things were. It was possible to see and touch the switch port…Read More
Not networking, but a little gotcha that caught me out today with very slow boot times for ESXi V5.5 associated with RDM’s and MSCS configured LUN’s mounted via VPLEX.

There is a new free utility called Local Administrator Password Solution (LAPS) which enhances a security on domain managed workstations (servers) by managing the local admin passwords in the domain on those systems. The tool might interest a system admins which want to reinforce their domain security as it allows setting a different, random password […] Read the full post Free Tool – Local Administrator Password Solution (LAPS) at ESX Virtualization.
