VMware’s Photon and containers in VMware
Posted by Gary Williams on April 12, 2017
4.5/5 (2)

The past month has been categorized as something of a performance and upgrades challenge as one of the constant calls I hear is “application X is going to slow”, of course, a month ago it was fine but today it isn’t and normally this is just down to increasing load.
One of the common fixes for increasing load is to add more vCPU and RAM but often that can cause its own set of problems especially when NUMA boundaries are crossed and when vCPU contention pushes things a little too far.
The second part of the challenge is the upgrade challenge where various applications need upgrading but there are dependency chains to take into account, this is the sort of thing where application X needs a very specific version of application y. In those cases, an upgrade is much easier to do by reinstalling the OS and starting again then transferring the data across!

As a potential solution to these issues that I’ve been exploring is Docker on VMWare’s Photon OS.

vSphere 6.5: HA & DRS improvements. Part 2
Posted by Askar Kopbayev on March 3, 2017
5/5 (1)

In Part II we will review the remaining improvements in vSphere Availability and Resource Management brought by vSphere 6.5.

Challenge: HA Restart priorities are not flexible enough

Description

Modern applications can be very complex and may consist of more than one server. Very often multi-tier applications require specific restart order, e.g. classic scheme DB – App – Web.  For instance, if an application server powers on before the database server the application will fail to start. To make it worse, there is no guarantee that the application server will automatically recover after DB server is powered on.  Sometimes the application server will have to be rebooted to restore the service. Moreover, there could be inter-application dependencies which make the situation even more complicated.

Connect Veeam to vCenter and add a Backup repository
Posted by Romain Serre on February 27, 2017
5/5 (1)

In the previous topic, we have seen how to install and update Veeam Backup & Replication 9.5. In this topic, we will prepare the environment. We will connect to vCenter to be able to backup virtual machines and we will add a backup repository.

Connect Veeam to vCenter 6.5

In my lab environment, I have deployed a vCenter Server Appliance 6.5 (VCSA). The VCSA FQDN is admin.vsphere.lab.

First, you need an administrator user to connect to vCenter from Veeam. From vCenter, add a new user as below. I have called mine Veeam.

Encryption of VMware vSphere 6.5 virtual machines and vMotion migrations. And their performance
Posted by Alex Samoylenko on January 26, 2017
5/5 (2)

As many admins of virtual infrastructures know, for the first time ever, VMware vSphere 6.5 received the long awaited encryption feature of both virtual disks content and vMotion hot migrations.

The VMs encryption works based on AES-NI algorithm, and the key management is carried out based on KMIP 1.1 standard. When I/O operation comes to the disk of the virtual machine, it is immediately encrypted on-the-fly, which provides complete security against data security attack.

Create an ESXi 6.5 installation USB under two minutes
Posted by Vladan Seget on January 24, 2017
5/5 (5)

The Installation of ESXi 6.5 did not change much since previous release. After you’re download your installation ISO, you need to burn it to a CD-ROM in order to proceed with installation. Know that there is a way to install ESXi from USB stick too. And in this post we will prepare one. You as an administrator or consultant have to have your toolkit with the latest ESXi installer ready in your pocket, so today we’ll show one of the methods to create an ESXi 6.5 installation USB under two minutes.

While this method of creation of USB media is quick and it is done under two minutes, it is not always obvious to deal with hardware compatibility and drivers and firmware (combination of those two) for latest vSphere 6.5. At the end of the post we’ll show you few ways how to deal with that.

VMware’s vRealize Log Insight – The easy way to get datacenter insight
Posted by Michael Ryom on December 21, 2016
5/5 (2)

For those of you who do not know vRealize Log Insight. It is a log collector and analyzer, with a pretty, simple and intuitive GUI. An easy way of managing logs and messages from all your datacenter devices. Best of all, it is not a VMware only product! In that sense that as long as the message is in syslog format it can be ingest by Log Insight. Wait, that is not all. If the device does not support syslog, like a Windows server. The Log Insight agent you can install on the OS in question. The Log Insight agent can handle Windows event viewer messages and log files of any kind. So even applications that do not adhere to any of the normal ways of logging messages (like syslog or windows event viewer), can still be collected, by specifying the location and format of the log file(s).

The latest updates in vSphere 6.5 and VSAN 6.5
Posted by Askar Kopbayev on October 18, 2016
4.88/5 (8)

 

This day has come – vSphere 6.5 has been just announced. As many of you I have been waiting for the presentation of new vSphere during VMworld event in the USA, but I guess VMware preferred to use vSphere 6.5 as a treat for those who were in doubt whether to attend VMworld Europe or not after all VMworld US were made available online to everyone; or perhaps VMware hasn’t decided what features should be included into the GA release.

In this post, I will try to cover all new features of vSphere 6.5 and VSAN 6.5, but if I missed something feel free to let me know by leaving a comment.

To be honest, there is so much to talk about and some of the new features require separate posts to be explained properly. Therefore, please don’t expect detailed review of the every single feature.. This is more ‘What’s new in vSphere 6.5 and VSAN 6.5′ overview, but in the future posts I will be talking about some of the most interesting improvements and enhancements in detail.

vSphere Auto Deploy
Posted by Askar Kopbayev on August 22, 2016
5/5 (1)

The Auto Deploy is one of the underestimated vSphere features. I have seen many vSphere Designs where using Auto Deploy was outlined as overcomplicating and manual build of ESXi servers was preferred. That is pretty frustrating as we, as IT professionals, strive to automate as much as possible in our day to day work.

Configuring Auto Deploy is definitely not as simple as VSAN for instance, but using Auto Deploy really pays off when you manage hundreds and thousands of ESXi hosts.
