Now let's get to the meat of this article and cover all of the third-party products for VMware ESX I could locate. Here is the list:

Vizioncore - Vizioncore offers esxRanger, esxMigrator, esxCharter, and esxReplicator. esxRanger is a popular backup application for VMware ESX Server. esxMigrator is a P2V conversion application, esxCharter is a performance monitoring application, and esxReplicator is used replicate virtual machines or SAN LUNs to other servers or SANs, either on the LAN or across the WAN.

Dunes VS-O and VD-O - VS-O offers a management layer on top of VMware Virtual Center or Microsoft Virtual Server which helps in virtual automation. VS-O is a type of virtual infrastructure management package. VD-O is used for VDI.

EsXpress - a scaleable and fault tolerant backup, restoration, and disaster recovery solution for VMware ESX. They offer the Virtual Backup Appliance (VBA)

Platespin - offers Power Convert and Power Recon. Power Convert is a P2V, V2V, and complete server workload management system (depending on the package you buy). Platespin also offers PowerRecon which collects and reports on all physical and virtual servers. PowerRecon will report the most efficient use of your hardware & software, as well as tell you how much you could save by virtualizing your systems (both in hardware and in cooling/electricity usage)

Veeam - offers Veeam Configurator, Reporter, FastSCP. Veeam configurator is used to extend the Virtual Center console and give you access to more options and flexibility than what Virtual Center provides. Veeam Reporter is used to document, discover, and create a visual diagram of your ESX server farm. Veeam FastSCP is used to transfer ISO files to your ESX server. They claim that FastSCP is 6 times faster than traditional SCP clients. Veeam also offers a couple of free utilites - Rootaccess Wizard for ESX and Veeam Monitor for VMware Server.

VMTS - offering a variety of FREE tools and scripts for VMware ESX Tools such as VMTS Patch Manager, SSH client for ESX, and more.

Of course, there are a number of companies making Virtual Desktop brokers used with Virtual Desktop Infrastructure (VDI).

In summary, the number of third-party tools for VMware ESX server continues to grow. If you are using ESX server already, I encourage you to consider some of these third party tools. While VMware has some excellent tools in their virtual infrastructure suite, there is always room for improving on those tools or complementing those tools.

On the Richard 's site there is a tool that I've not used but seems to be interesting to configure the VLAN on a single esx host and present on the other.

Citrix entered the datacenter and desktop virtualization markets with the recent acquisition of XenSource, a leader in enterprise-grade virtual infrastructure solutions. Citrix now offers the industry’s broadest end-to-end virtualization portfolio extending across servers, applications and desktops.

The acquisition moves Citrix into adjacent and fast growing datacenter and desktop virtualization markets. The combination of Citrix and XenSource brings together strong technical, customer, partner, channel and go-to-market synergies that will make virtualization solutions easier to use and dynamically combined more relevant to business. The acquisition will also extend Citrix’s leadership in the broader Application Delivery Infrastructure market by adding key enabling technologies that make the end-to-end computing environment far more flexible, dynamic and responsive to business change.

Virtualization has become one of the most talked-about technologies in recent years because it breaks the “hard-coded” link between hardware and software, allowing individual computing components to be dynamically combined and reassembled for maximum efficiency and agility. Citrix has long been the leading provider of virtualization technologies at the user tier of computing with products that deliver mission-critical applications to end users with the best performance, security and cost savings. This acquisition allows Citrix to extend its use of virtualization into the logic and data tier of applications, improving overall customer value and enhancing its position as the market leader in end-to-end application delivery infrastructure.
