vSphere Business Continuity Webcast

Next up in the vSphere 6 Webcast Series is the very important topic of business continuity.  For many, business continuity equals business productivity and application downtime needs to be minimized or eliminated.  Learn how vSphere 6 reduces downtime for applications and maximizes productivity for businesses.  Matt Meyers will lead our discussion on availability and data protection.

This webcast will occur on Tuesday June 30 at 9am PST and there will be a team present to answer questions you may have.  Register today for the free live webcast.

Agile Big Data Webcast

We are adding a special webcast to the vSphere 6 Webcast series.

The next webcast will be on the topic of agile Big Data happening on June 23 at 9am PST.

Learn how vSphere 6 + Big Data Extensions 2.2 can help you build an agile Big Data platform.      Provision your Hadoop clusters faster, simplify configuration and management of your nodes, efficiently scale and utilize resource saving you time and money, all with no impact on performance.  Justin Murray, our Big Data guru, will be sharing his insights and answer any questions you may have.

vSphere 6 Hardening Guide GA now Available

It’s time to release the vSphere 6.0 Hardening Guide! As I mentioned back in April, there are a lot of changes that have been made. In talking with customers and auditors in detail for the past year, the conclusion was reached that the Hardening Guide was

  1. Difficult to understand
  2. Contained a mix of
    • Operational Guidance - How you use the product in your environment
    • Programmatic Guidance - What settings should be applied OR audited

Basically, it was NOT easy to implement. And if security is too difficult to implement, people will either not do it or will do it poorly.

vSphere with Operations Management Product Walkthroughs

If you’ve ever tried to watch a product demo video, or tried to use it to show a product to someone else, often times you find yourself trying to pause the video at the exact right moment, and then having scrub backwards or forwards because you missed the timing.  At VMware we’ve created an alternative way ot showing demos, which we call Product Walkthroughs.  These are web-based demos that let you walk through a scenario screen-by-screen, at your own pace.  Each screen has annotations to explain what’s going on and markups that highlight important parts of the screen, both of which can be turned off if you want a clean view.

Although we have created Product Walkthroughs for numerous products and solutions, the ones I want to focus on are for vSphere 6 and vSphere with Operations Management.  Both of these provide a great way to learn about these products and their features at your own pace, as well as to show how something works to your colleagues (or bosses).  The one on vSphere 6 highlights the features in this major new release, with sections on:

and more.

The vSphere with Operations Management product walkthrough provides an in-depth look at all the features of its two major components, vSphere and vRealize Operations, including

So, check them out and let us know what you think!

VM Component Protection (VMCP)

vSphere 6.0 introduces a powerful new feature as part of vSphere HA called VM Component Protection (VMCP). VMCP protects virtual machines from storage related events, specifically Permanent Device Loss (PDL) and All Paths Down (APD) incidents.

Big Data Extensions Version 2.2 - What's New? A summary of the new features.

The new  vSphere Big Data Extensions Version 2.2 shipped on the 5th June 2015!

Here is a quick summary of the new features that appear in the 2.2 release. This is an exciting and much-awaited release. As always, refer to the technical documents and the release notes to get more detail on these subjects. 

• Support for the Latest Hadoop Distributions. BDE 2.2 supports the latest versions from the major Hadoop distribution vendors, including Bigtop 0.8, Cloudera CDH 5.4, Hortonworks HDP 2.2, MapR 4.1, and Pivotal PHD 3.0.

• Better Fully Qualified Domain Name (FQDN) Management. We found that some users had difficulty with generating FQDNs within their network for newly cloned virtual machines. BDE can now generate and propagate meaningful host names in FQDN form for your new  virtual machines that host the Hadoop nodes. The new FQDNs will be registered to a DNS server if you are using a Dynamic DNS server.

• Shrink clusters. You can now reduce (as well as expand) the number of worker virtual machines that belong to a running Hadoop cluster in an easy way. The virtual machines targeted for shrinking will be quiesced, withdrawn from the Hadoop cluster and then deleted to release any resources that they used completely.

• Active Directory/Lightweight Directory Access Protocol (AD/LDAP) integration. You can use an AD/LDAP server to manage the accounts generated by BDE within the Hadoop nodes . You can specify the accounts to be Hadoop users accounts and/or service accounts in an AD/LDAP server.

• vSphere 6.0 Instant Clone. BDE will, at the user's request, use Instant Clone technology to spin up new Hadoop VMs. This feature reduces the time of spinning up Hadoop VMs and the runtime footprint. This is an optional way to do this. You can choose to use the older "full clone" method also if you prefer to. We recommend that you use this new type of cloning for your test and development workloads to begin with.
• Centralised logging. You can configure BDE to direct logging information to an external syslog server including LogInsight.
• Quiesce the BDE management server. You can quiesce BDE management server with a command so that you can backup BDE management server's data for your clusters safely.
• Automatic GUI installation. BDE GUI is automatically registered to the vCenter after BDE is deployed.

• Support for the Latest Partner Hadoop Management Tools. BDE 2.2 supports Cloudera Manager 5.3, and Ambari 1.7. You have more flexibility to deploy Hadoop clusters, including a compute-only cluster,a  HBase-only cluster,a  data-compute separated cluster etc. even when using a Partner Hadoop Management tool.

• Support for the Latest Isilon Version. Fully automated process to deploy and manage compute only clusters on OneFS 7.2.

• Big Data Extensions Upgrade. You can upgrade Big Data Extensions 2.1 to the current version, Big Data Extensions 2.2, and preserve all the data for the Hadoop clusters that were created using Big Data Extensions 2.1. All of your existing clusters can be managed by Big Data Extensions once the upgrade completes.

• Localization. BDE is localized to 6 languages including DE, FR, ZH_CN, ZH_TW, KO, and JA.

Configure Auto Deploy Rules - PowerCLI

In the previous post Configure DHCP and TFTP for Auto Deploy, we discussed how to setup your DHCP and TFTP servers to allow your ESX hosts to PXE boot. However, once an ESX host boots, it will need directions to know what to boot. This is where Auto Deploy Rules come in. Continue reading

DRS Keeps VMs Happy

Since the introduction of Distributed Resource Scheduler (DRS) almost 10 years ago, it has become the most trusted way to ensure virtual machines are running at their peak performance. Over 80% of customers that have introduced DRS use it in fully automated mode, which allows for automatic placement and rebalance operations that simplifies capacity planning and administrative overhead.

There seems to be quite a bit of inaccurate information floating around recently about vSphere DRS. The most common thing I hear is that “DRS is focused on balancing hosts in the cluster, and is not focused on workload performance.”  Actually, nothing could be further from the truth, and hopefully this will help explain how DRS is working to keep your VMs performing optimally.
