StarWind VVols for VMware vSphere Environment

Introduction

VMDK file to LUN storage architecture has been the most usable scenario for years until VMware released Virtual Volumes in vSphere 6.0. In the case of an array with block access, own VMware file system – VMFS  – was used -, and NFS was used for file storage. The array capacity was divided into LUNs or NFS-shares and presented ESXi hosts in the datastore form. Frequently, datastore is a large capacity storage housing numerous VMs. In fact, allocating a separate datastore for each VM is quite inconvenient and time-consuming in terms of administration.

With this approach, the VM storage maintenance operations are at the datastore level, and not at the Virtual Machine level. The operations like snapshots, replication, deduplication, encryption, etc. are performed at the storage level, thus being implemented faster with no use of compute and networking resources. The traditional VM storage technology described in vSphere is still supported. At once, Virtual Volumes (VVols) is an object containing VM files virtual disks and their derivatives.

This handy and at the same time advanced technology was integrated with StarWind Products, that I am about to implement.

VMware vCenter Server Appliance Homelab tips
Posted by Vladan Seget on June 15, 2017
No ratings yet.

Many IT administrators or virtualization guys runs their homelabs at home. It is a good way to learn new technologies, be able to break things in a lab to get stronger skills.

It is sometimes a challenge, to squeeze as much RAM as possible from it. The main challenge is always a memory utilization. VMware VMs are getting memory hungry all the time and they are not “optimized” for Homelab use, but rather for production environments. Yes, it is the main purpose of those VMs after all.

One of the large VMs, but most critical, is VMware vCenter Server Appliance (VCSA). This product is becoming very popular within VMware communities and it is very easy to setup. Today we will have a look if we can do some optimizations and some “tweaks” to make it less memory hungry.

StarWind Virtual Storage Appliance Linux edition
Posted by Alex Bykovskyi on May 5, 2017
5/5 (1)

Introduction

This article describes the new StarWind Virtual Storage Appliance, which was released on 26th of April. StarWind has always been a Windows native solution. However, due to market trends and the huge interest of our customers, we have decided to work in Linux direction. The main goal of the article is to show what StarWind VSA can do for clients and how you can work with it.

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
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.
