VMware vCenter Server Appliance (VCSA) and after install tricks
Posted by Vladan Seget on April 10, 2017
5/5 (1)

It is not new that VMware vCenter Server Appliance (VCSA) is a very popular option, especially for small businesses which can save money on an additional Windows Server license.

It is a prepackaged and preconfigured virtual appliance with PostgreSQL database, vCenter server 6.5 components and also (in case you deploy “all-in-one” VM) Platform services Controller that contain all of the necessary services for running vCenter Server such as vCenter Single Sign-On, License service, and VMware Certificate Authority.

The VCSA is running Photon OS which is a VMware own lightweight distribution, optimized for fast booting, security, and scalability. During a long time, VMware was using Suse Linux Enterprise Server (SLES) distribution, but the fact that VMware did not own the stack was a break to faster development.

Virtual workload migration with VMware
Posted by Askar Kopbayev on March 27, 2017
No ratings yet.

It is quite surprising how many companies migrate virtual workload nowadays. There could be different reasons – expiring contract with the service provider, move to the new office, consolidation of resources to minimize Capex and Opex, but in every case, companies need efficient and flexible V2V migration solution.

Very often people think of migration in terms of moving data from one place to another. However, migration is much more than that. For instance, you would probably want VMs to keep the same IP addresses after the migration. Which means you need to consider stretching VLANs between the source and target locations in case you cannot migrate all VMs in particular subnet in one go. You must plan a network cutover too.

Veeam Backup Entreprise Manager is an optional component that enables to consolidate several Veeam Backup & Replication server through a single pane of glass. Veeam Backup Enterprise Manager provides a web-based interface to centrally control and manage all jobs. You can edit job, monitor them and have a consolidated view of the reporting of all Veeam Backup & Replication server. In this topic, we’ll see how to configure Veeam Backup Enterprise Manager.

Backup and restore your first VMware VM with Veeam
Posted by Romain Serre on March 8, 2017
No ratings yet.

In the previous topics, we have installed and updated Veeam B&R 9.5. Then we have connected Veeam to vCenter 6.5 to get visibility on VMware VM and backup them. To finish, we have added a backup repository to store backup files. Now we can backup a virtual machine. Once we have some restore points, we can also recover the VM.

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

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.

Capacity planning with vRops
Posted by Michael Ryom on January 18, 2017
5/5 (2)

Capacity planning is one of the tasks that every IT organization need to do, but most do very poorly. This is not out of bad will or lack of skills. Most often, it is because they lack a good way of dealing with all the changes, past, present and future. Most of them are also done reactively. Statistics may be pulled from vCenter and put into word or excel where graphs of past data points from a historical trend. This is then used to predict the future growth and based there of cluster sizing and purchasing decisions are made. Alternatively, the all too familiar, “we are out of resources. Hurry we need to buy more”, scenario comes into play. None of these capacity technics are very good. There is most properly a need to do things smarter.

VMware vSphere 6.5 – What to be aware of before upgrade?
Posted by Vladan Seget on December 6, 2016
4.67/5 (6)

VMware vSphere 6.5 has been released few weeks back and many users would like to hit the upgrade button. Not so fast. In this post I’ll talk a little bit about what to consider before upgrading to vSphere 6.5. One of the good news is that there are no new license keys needed for vSphere 6.5 so if you’re currently on vSphere 6.0 you don’t need to enter new license keys.

Planning is a pain, but it is necessary step. Also, playing with Firmware on your physical NIC cards and applying proper firmware-driver combination is a hard reality before even thinking going further…. I have experienced that recently when upgrading my pNICs to proper firmware/driver combination (Those were the x710-da2 Intel Hyper converged 10GbE adapters).

Below you’ll find few points which are essentials to every IT admin.
