As a result of this design, hosts have multiple ways of reaching a logical unit number (LUN). For most users, viewing and setting multipathing information is best handled with the VI Client. How to setup a test network in VMware & Virtual Box. New User’s Guide to Configuring VMware ESX Networking via CLI.
23 June 2009 A lot of the content on this site is oriented toward VMware ESX/ESXi users who have a pretty fair amount of experience. As I was working with some customers today, though, I realized that there really isn’t much content on this site for new users. That’s about to change. As the first in a series of posts, here’s some new user information on creating vSwitches and port groups in VMware ESX using the command-line interface (CLI). For new users who are seeking a thorough explanation of how VMware ESX networking functions, I’ll recommend a series of articles by Ken Cline titled The Great vSwitch Debate.
Before I get started it’s important to understand that, for the most part, the information in this article applies only to VMware ESX. The majority of all the networking configuration you will need to perform on VMware ESX boils down to just a couple commands: Configuring VMware ESX networking boils down to a couple basic tasks: Creating, Configuring, and Deleting vSwitches. VMware NSX: Game Changer for Data Center Networks. VMware's network virtualization product, NSX, may upend data center networks the same way the hypervisor changed servers. Now that VMware has conquered data center computing via server virtualization, the company is opening a beachhead on the network via its NSX product, which is being officially launched today at VMworld in San Francisco.
VMware NSX is a software-defined network (SDN) that uses controllers and overlay networking. I'll examine just a few of the key aspects of the announcement and how they apply to your data center strategy. Overlay networking refers to the use of protocols such as VXLAN and STT to create a virtual network between hypervisors. As data flows from the guest VMs and into the network, the Ethernet frames are encapsulated. I've written previously about the value of overlay networking, but the following are the key points to note about VMware's approach: Networks Agents as Software Controller-Based Networking Next page: Software Defined Data Centers 1 of 2.
Virtual Networking 101: Understanding VMware Networking. May 30, 2012By Petra Jorgenson On a basic, structural level, virtual networks in VMware aren’t that different from physical networks; vSphere is designed to mimic the functions of a physical network, so a lot of the network hardware you’ll find in the real world, you’ll find virtualized in VMware. If you understand how physical networks operate, then understanding virtual networking shouldn’t be too difficult.
Before jumping into an explanation of how VMware handles virtual networking, I’ll first provide a quick refresher of the basic equipment that makes up a physical network. If you already have a firm understanding of how networking works, then you can skip the following paragraph. To connect to a network, a computer must be network-capable, meaning that it must have a working network interface controller (NIC), also known as a network card or network adapter, installed. In VMware, switches are used to establish a connection between the virtual network and the physical network. Understanding Virtual Networking in VMware Workstation 9. Introduction In my opinion, VMware Workstation is the premier and ideal platform for virtualizing desktops on your local Windows or Linux laptop or desktop computer. This is because Workstation offers the most maturity and functionality out of any of the desktop-based hypervisors. Workstation has a strong snapshot manager, the greatest list of supported guest operating systems, remote virtual machine management/control with the new WSX (see my article – Managing VMware Workstation VMs Remotely with WSX), connectivity to vSphere in the datacenter for VM management and import/export and, finally, the most mature virtual networking.
What I’ll be focusing on in this article is how virtual networking works in VMware Workstation and what’s new related to virtual networking in Workstation version 9. Introduction to Virtual Networking in VMware Workstation It’s the virtual network, as created by VMware Workstation, which connects your virtual machines to the physical network. Additional notes: VMware vSphere 5 Host NIC Network Design Layout and vSwitch Configuration [Major Update] | Tech Blog | Blog. This is an update to an older post and I wanted to overhaul it for the Indy VMUG... This was also another VMworld submission that didn't get the votes. See what you guys are missing out on? :) As vSphere has progressed, my current 6, 10, and 12 NIC designs have slowly depreciated. In an effort to update these to VMware vSphere 5, I took the 2 most popular configurations of 6 and 10 NICs and updated the Visios to make them a bit more pretty.
I also don't know how much longer these will be necessary as the industry moves forward with 10GbE as a standard. The assumption of these physical NIC designs is that these hosts are going to be configured with Enterprise Plus Licensing so all the vSphere features can be used.

Connect to VMWare virtual machines using Remote Desktop. Had a short training on VMWare on Tuesday, the software development department finally got the official permission (read: get a license) to use VMWare Workstation. I’m no stranger to Virtual Machines (VMs) – started playing with Virtual PC 2005 a fwe years back and I understood the general concepts of hardware virtualization. The biggest problem I have with VMs in general is the slowness; I’d rather develop directly on my PC, which is faster. Can’t say I’ve delved deep into it, but I know enough to utilize it and be dangerous Regardless, virtual machines provide a way to simulate multiple computers and I’ve done 3-tier software testing (client to app server using WCF and app server to SQL 2005 backend) to verify our framework can support both 2-tier (client –> DB) and 3-tier deployments.
Fast forward to the current time, I’d like to be able to do some coding on Windows 7; unfortunately Windows 7 is not quite sanctioned yet to be deployed, and it’s a pain to have to dual-boot. . . VMware wants to be the VMware of Networking « IT 2.0. By Massimo, on April 17th, 2012 There have been a lot of discussions lately about SDN (Software Defined Networking). Arguably SDN may mean a lot of different things to a lot of different people. If you ask the like of Facebook, Google and academic researchers they will probably tell you that SDN is all about gaining full visibility (and control) on how packets flow on the network.
People and organizations that are closer to the commercial world may tell you that SDN is all about creating an abstraction layer (virtualization anyone?) In the network – from layer 2 all the way to layer 7. That abstraction will allow you to become more agile and flexible in how you define the network and security characteristics for the applications you are deploying. In fact (compute) virtualization can reduce the time to deploy an application from weeks down to minutes. I’d like to focus on the latter definition of SDN. Look at the picture. Massimo. VMware storage: SAN configuration basics. VMware storage entails more than simply mapping a logical unit number (LUN) to a physical server. VMware’s vSphere enables system administrators to create multiple virtual servers on a single physical server chassis. The underlying hypervisor, vSphere ESXi, can use both internal and external storage devices for guest virtual machines.
In this article we will discuss the basics of using storage area network (SAN) storage on vSphere and the factors administrators should consider when planning a shared SAN storage deployment. VMware storage: SAN basics vSphere supports internally-connected disks that include JBODs, hardware RAID arrays, solid-state disks and PCIe SSD cards. SAN storage, however, provides a shared, highly available and resilient storage platform that can scale to a multi-server deployment. It is possible to use NAS and SAN-based storage products with vSphere, but in this article we will consider only SAN, or block-based devices.

Software-Defined Storage (SDS) and Storage Virtualization. VMworld 2014 VMware vCloud Air and ViPR Object Storage. This one is short and sweet! The vCloud Hybrid Service is no more, and is now VMware vCloud Air! Furthermore – it keeps getting bigger (more locations), and better (more capabilities – DR as a Service, Backup as a Service, and Platform as a Service) – with one of the new additions being one of the industries’ richest web-scale, geo-dispersed and efficient - which can translate into the lowest cost model – object (and HDFS!) Store! No cloud service is really complete without PaaS and Object stores – and it’s great that the vCloud Air service is getting them… What is delivering the underlying Object/HDFS Storage?
Answer – EMC ViPR. Yup – the VMware vCloud Air Object Storage service runs on EMC ViPR Object! For the doubters for the concept of the Federation, sure you can see examples where the Federation parties are “Open” (which we are – see how VMware and EMC are embracing Openstack a little differently, or Pivotal running on AWS, or EMC’s HDFS offerings partnering with Cloudera). vSphere Storage vMotion: Storage Management & Virtual Machine Migration. VMware vSphere Storage Appliance Documentation. VMware Storage Integration & Top Storage Vendors. Research done in collaboration with Stuart Miniman and Nick Allen Introduction In April 2011 Wikibon ran a survey looking at the area of storage and VMware. The results showed that EMC and NetApp had a clear lead in the number of respondents that selected them as the best VMware storage and as the primary VMware storage vendor. Wikibon has further analyzed the results of the survey, including a detailed analysis of the degree of integration.
Figure 1 – Relative Positioning of VMware Storage Integration by VendorSource: Wikibon Survey April 2011, n=361, and detailed analysis of vendor implementations. Wikibon believes that practitioners can use the methodology in this report to help position the importance of integration features for their own VMware storage decisions and to help decide which vendors to include in RFPs. Vendors and Storage Assessed Wikibon looked at the major storage offerings from the six (6) largest storage vendors. Rating Importance of Integration Features Conclusions. VMware's Virtual SAN Threatens Traditional Data Storage Models. VMware has launched the final part of its software defined data center puzzle: a virtual SAN product called Virtual SAN. The product has been in beta testing for the last six months, with around 12,000 customers, but there were still plenty of surprise announcements made at the launch event on March 6. The biggest of these was the maximum size of its Virtual SAN.
Previously VMware had said that this would be 8 server nodes, and then 16. But VMware CEO Pat Gelsinger announced that the product has been upgraded to support 32 nodes. Now for some math. "This is a monster," said Gelsinger, echoing the monster VM concept that the company introduced in 2011 with the introduction of vSphere 5.
He added that performance scales linearly - a 16 node setup offers 1M IOPS, a 32 node one offers 2M IOPS - and despite his previous comment about 32 nodes being monstrous, he hinted that even larger Virtual SANs are on the roadmap: "There will be more in the future. It turns out that there's two ways. VMware Networking and Storage.
