I normally bring you information about business critical apps such as Oracle, SAP, Java, SQL Server and the like, and the infrastructure configurations and performance that support them. But if you look at it any Virtual Desktop Infrastructure that is widely deployed to a larger percentage of an organisation, it is a business critical app. I’ve been involved in architecting and troubleshooting a few VDI environments over the last few years, one as big as 6,000 seats using Horizon View, and if we go back a bi,t a much larger environment using Citrix XenApp. I’ve seen many of the challenges, and I’ve seen what it takes to succeed. This is why today’s announcement from Nutanix is exciting, in that it brings all the benefits of VDI to organisations of any size, without all the risk and complexity that might have come along with it. Let’s take a look at the announcement and what an environment and infrastructure to support 10,000 Power Users’ VDI desktops might look like on Nutanix.
Another year has flown by, and what a year it was, and now we’re in a new year and I’m a year older and hopefully a little wiser, we never learn less. The great thing about being in the IT industry and especially being involved with Virtualization, Cloud and Software Defined Datacenters, there is always so a lot to learn and things are changing at an ever faster pace. All the time the economics and customers benefits are rapidly increasing all the time. I mean we don’t just do things because they are cool and technically interesting, there has to be an ROI for our customers, partners and customers organizations. It was great for me to personally be involved in revolutionizing many customers economics of delivering IT infrastructure and applications services throughout 2013, especially with the many Unix to VMware migration projects I was involved with. So this article will reflect on some of the highlights of 2013.
If you’re upgrading from vSphere 5.1 to vSphere 5.5 and you ARE NOT using Custom CA SSL Certificates then you might run into an error. The error will be encountered during the upgrade of SSO, and specifically the Lookup Service, and only occurs in specific conditions, such as when using the default VMware Self-Signed Certificates. If you run into this problem your upgrade process will roll back, but leave behind some upgrade files that need to be cleaned up. This article will briefly touch on the recommended solution to this problem.
VSS Labs will be showcasing its latest offerings at the New Innovator Pavilion at Booth 2035 at VMworld USA 2013. The two offerings include it’s globally successful and VMware exclusive Cloud Migration Portal and it’s new SSL Certificate lifecycle management product vCert Manager. Lets have a look at what these two products are all about to give you a glimpse of what you might find out at their booth at VMworld USA.
One of the most important documents for any vSphere administrator or architect has been released. The vSphere 5.1 Hardening Guide is now available. The guide was announced on the vSphere Blog by Mike Foley – vSphere 5.1 Hardening Guide – Official Release. I’d like to thank Mike and the rest of the VMware Security Team that was involved in putting this invaluable resource together. It has been reformatted from the previous version to make it easier to use. I think you’ll all like the new improvements.
I was upgrading my VMware View environment recently from 5.0 to 5.1 and wrote about some initial problems in my article Trouble Recomposing View 5.x Desktops After Upgrade to vSphere 5.0 U2. After I had resolved those initial problems I needed to load my internal Root CA certificate onto all my company’s iPhone’s and iPad’s. This is because one of the big changes or improvements in View 5.1 is with security and you now need trusted certificates in order to connect to any of the desktops. Fortunately there is no need to purchase expensive public certificates if you have an internal corporate PKI / CA’s already configured, unless you want to. This article will show you how you can easily get your iPhones or iPad’s to trust your corporate CA certificates for use with VMware View.
Microsoft recently issued a security advisory and a patch that blocks any certificates with a key length less than 1024 bits. This has impacted a wide variety of systems including VMware Site Recovery Manager 5.0 and below. This article will provide you a way to quickly regenerate the self-signed SRM certificates.
Recently I wrote about Updating CA SSL Certificates in vSphere 5.1 which applied to the Windows installable version of the vCenter 5.1 and it’s supporting components including SSO. VMware has now also released the instructions to update the CA SSL certificates in the vSphere 5.1 vCenter Virtual Appliance.
Over the past few weeks I have been working behind the scenes with a team of people at VMware spread around the globe on the process to successfully change out the self-signed certificates in vSphere 5.1. With the introduction of Single Sign-On in vSphere 5.1 the process is somewhat more complicated than vSphere 5 (ok quite a lot more complicated). But now I’m able to bring you some of the solutions you’ve all been waiting for.
