vSphere Replication 6.0 Compression

VMware recently introduced vSphere version 6.0. One of the features of vSphere 6.0 is vSphere Replication 6.0, which is included in the Essentials Plus Kit and higher editions of vSphere. The reason I mention that explicitly is there are still many VMware customers and partners that do not realize they have access to a mature, proven host-based replication technology for their vSphere virtual machines. vSphere Replication is also compatible with VMware Virtual SAN and vCenter Site Recovery Manager.

I recently posted a blog article that briefly covers the new features of vSphere Data Protection and vSphere Replication. In the article you are reading now, we will dig into the newly added option for enabling compression in vSphere Replication to reduce the amount of bandwidth consumed when replicating virtual machines.

VMware Certificate Authority overview and using VMCA Root Certificates in a browser

 

With vSphere 6.0 the vCenter Virtual Server Appliance (VCSA), now has a component called the Platform Services Controller (PSC). The PSC handles things like SSO and the License Server and ships with its own Certificate Authority called VMware Certificate Authority (VMCA). In this blog post we’ll quickly go over some of the modes of VMCA operation and how to download and install the VMCA root certificate into your browser.

Oracle Licensing On VMware Webinar

VMware is announcing the sponsorship of a webinar to address confusion on the subject of licensing Oracle Software running on vSphere. Database Trends and Analysis will host the webinar. Please use the link below to register. Don Sullivan will moderate a discussion between David Welch of House Of Brick and Daniel Hesselink of License Consulting. The small description below describes the event perfectly.

Many organizations that run or plan to run their Oracle Business Critical Applications on VMware virtualization do not understand that the Oracle contract is agnostic to VMware and how that translates to their infrastructure. VMware, in partnership with DBTA has invited the world’s most recognizable experts in this subject to join us on a webinar for a frank presentation and conversation about Oracle on VMware licensing by the contract.

vSphere 6 Web Client

With the recent announcement of VMware vSphere 6, I can finally start talking about the improvements we’ve made for vSphere 6 Web Client.  Over 100 enhancements, with some user actions performing 5x faster.  There are excel sheets and graphs full of performance data, but the best way to see the difference is to experience it yourself.  If you’ve been wary of using vSphere Web Client in the past, you should give it another shot with vSphere 6.

In my time here I’ve heard of many tips on using Web Client that I didn’t learn during training or while using it directly.  I thought it would be helpful to put all of these learnings in one place.  I’m sure many of you reading this know about some of these tips, but hopefully there are some new ones in there that are helpful to you as well.  This is a living document, so if there are tips and tricks not on the list, please share with the rest of us by adding it to the list.  I should stress that this is not an official VMware document:

There are also many enhancements in the vSphere 6 Web Client, some of which are highlighted below:

  • Controlling “All Users’ Tasks” for performance

We know that the All Users’ Tasks view of Recent Tasks is an important feature, but  it also turns out to be an incredibly “heavy” feature, which can quickly spiral out of control and impact vCenter Server performance.  The focus of this version of vSphere Web Client was improving performance and giving you more control on customizing your experience.  In order to achieve both of these goals, we had to make it a bit harder to get to All Users’ Tasks.  This will help ensure that your systems will run smoother out of the box, with the option to enable the feature if you need it.  We are also actively working on a better solution for this feature, but couldn’t get it in time for this release.

You’ll see some instructions when you first select All Users’ Tasks, and more detailed steps are in the Release Notes, but I included them here for reference.  Once you’ve enabled this feature, it becomes the default view:

A) Click More Tasks in the Recent Tasks panel to view all users’ tasks.

OR

B) Edit the webclient.properties file and change the “show.allusers.tasks” setting. For large vSphere environments, changing the “show.allusers.tasks” setting can potentially impact performance.

1. Locate the webclient.properties file

For the vCenter Server Appliance, the file is located in the /etc/vmware/vsphere-client/webclient.properties directory.

For vCenter Server on Windows, the file is located in the C:\ProgramData\VMware\vCenterServer\cfg\vsphere-client\webclient.properties directory.

2. Edit the file using a text editor and change show.allusers.tasks=false to show.allusers.tasks=true.

3. That’s it!  No restart of anything should be required.  Go to vSphere Web Client, select “All Users’ Tasks” and it should work.

  • Many performance enhancements

Performance was the primary goal of this release of vSphere Web Client.  Efforts were made to improve the performance of every portion of the interface, and you should see these improvements when you start using vSphere 6.  Here are some of the major areas we worked on: Login and Home page, Summary pages, Networking pages, Related Objects lists, General Navigation, Performance Charts, Action Menus (right click), and reducing unnecessary data retrieval, which also serves to lighten load on vCenter Server.

The net result is that the vSphere 6 Web Client is an entirely new experience and easier to use than previous versions of vSphere Web Client.

  • Tasks where they belong

This was shown at VMworld, but is worth another mention: The tasks pane is now back at the bottom, giving you room to see the information you need.

Tasks at bottom

This comes along with the ability to move and resize panes (we call this Dockable UI), allowing you to customize it to your liking, such as below where Alarms and Work in Progress have been moved to provide a larger workspace.

Dockable UI

  • Reorganized Action menus (right click)

Action menus have been reorganized and flattened so that your actions are easier to find, and placed more familiarly.  It should be much easier to pick up as you transition from the old desktop client to vSphere Web Client.

Action Menus

  • Home menu navigation

The new and improved home button now shows a navigation menu which allows you to jump from wherever you are to one of the common views.  You can now get back to any of the major inventory trees from anywhere in one click!

Homeburger

I hope this overview encourages you to upgrade your existing vCenter Servers to vSphere 6 so that you can experience these improvements (and more!) that we’ve made.

What’s New with vSphere Data Protection 6.0 and vSphere Replication 6.0

There are many interesting items coming out of VMware’s 28 Days of February where customers can learn more about “One Cloud, Any Application, Any Device”. A couple of the biggest items are the announcements of vSphere 6.0 and Virtual SAN 6.0. In this article, we will look at what is new with two of the more popular vSphere features: vSphere Data Protection and vSphere Replication. Perhaps the biggest news with these two features is around vSphere Data Protection. Before vSphere 6.0 and vSphere Data Protection 6.0, there were two editions of vSphere Data Protection: vSphere Data Protection, included with vSphere, and vSphere Data Protection Advanced, which was sold separately. With the release of vSphere Data Protection 6.0, all vSphere Data Protection Advanced functionality has been consolidated into vSphere Data Protection 6.0 and included with vSphere 6.0 Essentials Plus Kit and higher editions. Keep reading to learn more about the advanced functionality now included as part of vSphere Data Protection 6.0.

vSphere 6 – Clarifying the misinformation

With the Announcement of vSphere 6 this week there is a lot of information being published by various sources. Some of that information is based on old beta builds and is much different than what we’ll see in the final product. In this post I aim to correct some of the information based on the beta builds that’s floating around out there.

First off there’s confusion on the maximum number of virtual machines per cluster vSphere 6 supports. This is in part my fault, when we wrote the What’s New in vSphere 6 white paper the number was 6000. Additional scale testing has been done and that number is now 8000. The what’s new paper will be updated soon to reflect this.

vSphere 6.0 Hardening Guide – Overview of coming changes

The vSphere Hardening Guide provides guidance on how to securely deploy VMware vSphere in a production environment. The vSphere Hardening Guide also serves as a foundation upon which regulatory compliance objectives are built. These organizations map compliance guidelines with vSphere Hardening Guide guidelines.

Hardening Guides are an industry recognized method of implementing stricter security to meet regulatory and local security standards above and beyond frameworks like Common Criteria.

Version 6.0 of the vSphere Hardening Guide is the next step in the evolution of the guide. A goal of the vSphere 6.0 Hardening Guide is to make the guide easier to implement and assess.

The intent of this article is to go over some of the major changes that come with the new 6.0 guide prior to its release. Consider this your “heads up”.
