64TB VMDKs? Yes we can.

Here’s a tasty tidbit for you – in the just announced vSphere 5.5, we can now create 64TB VMDK files.  While much of vSphere 5.5 offers a 2x increase in configuration maximums over vSphere 5.1, the increase in VMDK size is a whopping 32x.  (It may actually be a bit less – I’m not sure if the -512B caveat comes into play on the virtual disk size for vSphere 5.5.  I didn’t think to test this out in the lab during my beta testing… the max size is actually 62.9TB as space is reserved in the containing VMFS for snapshots, metadata, etc.). Now just because you can, doesn’t mean you should.  I … [Read more...]

Going Nostradamus Style on VMworld 2013

It's hard to believe that VMworld 2013 is upon us.  Before last year's show I wrote a couple posts on my predictions for VMworld 2012 (here and here).  A good number of my predictions were correct on new products, services, and overall direction for VMware.  Emboldened by my future telling success, I thought I would try to do the same this year.  So without further ado, here's what I see coming at VMworld 2013, based on the VMworld 2013 Content Catalog, earlier announcements, rumors, social media hints, and pure conjecture. A Narrowed Focus First prediction: we'll see a narrowing of focus … [Read more...]

PCoIP Packet Loss? Don’t Blame the Network!

Several months ago I was called into a new customer to diagnose some odd behavior in their VMware View environment. The organization was struggling with constant disconnects and generally poor performance on their View desktops. When users weren’t being randomly disconnected from their desktops, the users experienced lag when dragging windows between multiple monitors, ‘choppy’ graphics/video, and slow application launching. The problems occurred with local and remote users (both WAN and LAN could be involved).  The customer had done some troubleshooting, worked with VMware Support and the … [Read more...]

Multipathing Support in vSphere Standard Edition

A customer recently asked me if storage multipathing is supported in vSphere Standard Edition.  The customer had reviewed the vSphere Editions comparison chart at https://www.vmware.com/products/datacenter-virtualization/vsphere/compare-editions.html and saw that Standard Edition did not include the 'Storage APIs for Array Integration, Multipathing' feature.  While the answer was quick and easy, I saw a good chance to provide some detailed information to the customer to better equip them to make an informed purchasing decision and to run their vSphere environment in the long run.  So what is … [Read more...]

Updated HAProxy Load Balancer Virtual Appliance

Last year I shared a free load balancer virtual appliance for VMware View that I created on SuSE Studio.  The load balancer uses HAProxy and came with a very basic configuration for use with VMware Horizon View Connection Servers or Security Servers.  The appliance has been downloaded a few hundred times and has been useful to me in my own home lab. Since publishing the appliance I have made several changes to the configuration and thought I would share those updates. You can download the latest version of the appliance in OVF format here: … [Read more...]

Conccurrent User Licensing for VMware Horizon Suite

VMware has made some changes to the Horizon Suite licensing since my last post about VMware’s Horizon Suite licensing and promotions.  The changes are included in the VMware End-User Computing Licensing, Pricing and Packaging Whitepaper, but are not well called out.  Here’s what you need to know about the licensing changes. Horizon Suite (a combination of Horizon View for virtual desktops, Horizon Mirage for physical desktop management, and Horizon Workspace for application and data presentation and management) is now available in a Concurrent User scheme.  Previously, the Suite was only … [Read more...]

Horizon View vs. Horizon Mirage

I recently covered the launch of VMware’s Horizon Suite of End User Computing (EUC) products, including VMware Horizon View, VMware Horizon Mirage, and VMware Horizon Workspace.  The products present a set of tools that enable IT to exercise comprehensive end-point management while delivering a unified user experience across a variety of devices and access methods. Today, I want to focus a bit more on View and Mirage. Specifically, when would you choose one solution over the other? Let’s briefly review each product. VMware Horizon View provides a virtual desktop infrastructure (VDI) … [Read more...]

Updated VMware Horizon View Visio Shapes Stencil

It's been about 9 months since I published my own set of Visio shapes for VMware vSphere and Horizon View.  The VMware Visio stencils have been quite popular, with the pages that host them seeing more than 37,000 page views since I first published them.  I've since updated both stencils with new shapes and diagrams as I've worked on different projects at Clearpath.  Most of the changes are in the Horizon View Visio Stencil, with new shapes and diagrams.  I included some hand-drawn shapes for Horizon View for some fun whiteboard like diagrams that I'll be using in some posts very soon - the … [Read more...]

At EMC World yesterday, the newly formed joint venture between EMC and VMware, along with a strategic investment by General Electric (GE) was discussed by Paul Maritz (former VMware CEO) in the morning’s keynote address.  Pivotal combines intellectual property and engineering resources (1200 employees) from both EMC and VMware to focus on solving big and fast data problems.  Pivotal combines solutions such as EMC Greenplum and VMware Cetas to serve and analyze ‘Big Data’, VMware Gemfire to rapidly ingest ‘Fast Data’, VMware’s Spring and vFabric technologies, and Pivotal Labs software for rapid … [Read more...]
