We got a question this morning on twitter from a customer asking for our best practices for setting up iSCSI storage and vMotion traffic on a VLAN.
The question caused a bit of a discussion here amongst our Tech Support staff and the answer it seems is too long to fit into a Tweet! Instead, here’s what you need to know if you are working on the best design for your VLANS.
iSCSI and vMotion on the same pipe (VLAN) is a big no-no unless you are using multiple teamed 1GbE uplinks or 10GbE uplinks with NIOC to avoid the two stomping on one another.
While vMotion traffic can be turned off/on/reconfigured on the fly, iSCSI traffic does not handle any changes to the underlying network (though great improvements have been made 5.1/5.5) on the fly. You will need to take a maintenance window to reconfigure how you want your VLANs to function – especially for the iSCSI network – and then (more than likely) perform a rolling reboot of all hosts. If iSCSI traffic is already VLAN’d off, you should just leave the iSCSI traffic where it is as to avoid taking down the whole environment and just move the vMotion network to a separate VLAN.
VMware recently launched the new VMWARE Secure Data Transfer portal which offers the ability to upload diagnostic information and files to VMware in a safe and secure way.
To address a Support Request, VMware Technical Support may request diagnostic information from the affected VMware products. Our video today provides a demonstration of the procedures necessary to upload diagnostic information to VMware using the Secure FTP (sftpsite.vmware.com) portal.
Uploading diagnostic information to VMware using the Secure FTP portal includes these methods:
Using your web browser and the HTML Interface
Using your web browser and the Java Applet
Using the command-line from a Linux operating system
Using third-party clients
Internet Explorer 9 and above is supported.
Other supported browsers include Firefox, Chrome, and Safari.
When uploading with Internet Explorer 10/11, you may have to switch to compatibility mode.
Do not use the HTML interface to upload files larger than 2 GB.
A new year is upon us and with it brings some new videos!
The first video of 2014 is for our VMware Fusion users and features a demonstration showing how you can install OS X 10.9 Mavericks as a guest operating system inside of a virtual machine running on VMware Fusion 6.
Apple’s End User license agreement allows you to install up to two additional copies of Mac OS X 10.9 on a Mac that is already running a retail version of the operating system and not a pre-installed version.
The installation sequence demonstrated within this video has been shortened for demonstration purposes. Actual installation will take several minutes to complete.
Seasonal greetings from the KBTV team here at VMware.
As it is the time of year for giving, today we are giving our vSphere 5.5 users a small present of three new short videos which demonstrate how to allocate, adjust, and disable vSphere Flash resources to a virtual machine in vSphere 5.5
The videos are based on the following VMware Knowledge Base articles:
One thing that catches a few customers up is the process of installing async drivers in their ESXi host … We have a KB article on the topic here, but there is more than one method to choose from and preparation steps involved. Since these steps might seem a little tricky, we decided a quick, live video explaining the topic might help many of you.
We called upon Kiwi Ssennyonjo to walk us through the salient points.
VMware ESXi 5.5 allows you to upgrade from previous ESXi versions using several different methods. These methods are described and outlined in VMware Knowledge Base article Methods for upgrading to ESXi 5.5 (2058352).
In this new video tutorial we demonstrate how you can upgrade from VMware ESXi 5.1 to ESXi 5.5 using the Interactive Installer that is supplied on the ESXi 5.5 Installation Media. We’ll show you the step-by-step procedure for performing a basic upgrade from ESXi version 5.1 to version 5.5 using the Interactive Installation method, however the instructions apply to older versions of ESXi as well.
