VMware SDDC Architects Group

By admin on September 11, 2013 in General

During VMworld VMware launched a Software Defined Data Center community, where architects could go for a few drinks and discuss all things SDDC. This was a really cool idea, and allowed people to ask questions about the content they had seen during the course of VMworld. Now that VMworld is over, people have been asking “where do we go for more information? Who can we bounce ideas off? Who can we speak too?” The answer is: VMware SDDC Architects Group VMware has recently launched a LinkedIN group titled “VMware SDDC Architects” where everyone who is interested in SDDC Architecture can go for discussions and further information. The description of the LinkedIN group: Having pioneered the technology behind the Software-Defined Data Center, VMware is now helping support technical architects who have led its adoption. Apply to this private discussion group to join discussions, share insights, and help shape the data center […]

VMware Virtual SAN Scalability Limits – VSAN

By admin on September 10, 2013 in Storage

I have had a few questions off people recently asking what are the scalability limits of the new VMware Virtual SAN. I thought I would post a quick table to show these. Description Limit Maximum number of disk stripes 12 Maximum number of failures tolerated 3 No of VSAN hosts per Cluster 8 Max number of IOps 120,000 Max number of Parallel vMotion per VSAN cluster 8 Max number of Parallel SvMotion per VSAN cluster 2 Max number of VMs per host 100 Max number of VMs per (evenly distrubted) VSAN cluster 800 Max number of disk groups per host 5 Max number of hard disks per disk group 6 Hopefully by providing these numbers, if you are thinking about implementing VMware Virtual SAN in your environments it will help you with the design. Note: Please remember that with the release of VMware vSphere 5.5, the VMware Virtual SAN product […]

VMware vCloud Director 5.5 new features

By admin on September 4, 2013 in VMware Posts

With the announcement of VMware vCloud Director 5.5 I thought it would be a good idea to list the new features that are included in vCloud Director 5.5. I would like to thank my colleague Ananda Kammampati for producing this extensive list. vCloud Director 5.5 new features Official support for Virtual Appliance form factor (but still not in production) Catalog Sharing and Synchronizing Versioning support vApp Provisioning and Lifecycle Support for cloning of running vApps with memory state Added OVF import/export features VCD 5.5 Virtual Appliance The Virtual appliance form factor of VCD 5.5 is now officially supported, however full support does not mean it is available for deployment in Production environments. Catalog Sharing and Synchronizing VCD 5.5 Administrator has the ability to limit the organizations with which one can share the catalogs. It can share the catalogs between VCD instances. This works in a Publisher/Subscriber model Catalogs can be […]

VMworld 2013 recap – Day 1

By admin on August 27, 2013 in VMworld

The day began with meeting up with Aidan Dalgleish and Kamau Wanguhu at the Hilton lobby, with us putting last minute changes to our slide deck for session VSVC7371. Well mainly it was Aidan being the OCD expert he is putting last minute changes to slide deck. We went straight to the speaker lounge and updated the presentation. Keynote After grabbing breakfast it was time to head to the keynote. This was going to be the first keynote Pat Gelsinger presented. I enjoyed this keynote, it was a different angle to what we have seen in the past from Paul Maritz, Pat poked fun at himself, showing off pictures of him as a dragon slayer among others. It was good fun. Then the moment came in the keynote where Pat announced the general availability of vSphere 5.5 and I was able to publish two of my articles I have had […]

Configure Disk Redundancy VMware VSAN – Virtual SAN

By admin on August 26, 2013 in Storage, VMware Posts

This article demonstrates demonstrates how to configure disk redundancy VMware VSAN and is a follow on post from my How to enable VMware VSAN The previous article showed how to configure a vSphere cluster for use with VMware VSAN. Configure Disk Redundancy in VMware VSAN When we configure Disk redundancy in VMware VSAN we do not setup any hardware based RAID configuration (remember the design consideration, this was a pre-requisite to have Pass-Through RAID Controllers). So how do we ensure data protection? VMware VSAN uses Storage policies to do this. These can be found in vCenter Home -> Rules and Profiles -> VM Storage Profiles. Using VM Storage Profiles you can assign capabilities to storage. In a Cloud environment, we like to use Gold, Silver and Bronze to determine our storage capabilities. We can easily create these policies to now match the capabilities of the storage. We have a number […]
