Configure Disk Redundancy VMware VSAN – Virtual SAN
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 […]
VMware VSAN – Virtual SAN – How to configure
This article shows how to enable a VMware Virtual SAN (VSAN) cluster within VMware vSphere. If you are unfamiliar with VSAN, and what it is, I recommend reading the following articles. Duncan Epping’s Tech Preview of Distributed Storage Cormac Hogan’s Distributed Storage Tech Preview Lets start off by looking at the Pre-requisites of VMware VSAN, what do we need in place before we begin the configuration. Pre-requisites There are a number of pre-requisites that are needed, prior to configuring a vSphere cluster to participate as a VSAN. The following list shows the minimum requirements to implement a VSAN. Minimum of three hosts. Each storage* host has a minimum of one SSD and one spindle hard disk. Each storage* host has a Pass-thru RAID controller as specified in the HCL. The RAID controller must be able to present disks directly to the host without a RAID configuration. 10GB Network. (1GB network […]
VMware vCloud Architecture Toolkit – vCAT Book released
I am pleased to announce that my first book I co-authored has been released on Amazon. This is really exciting news, which I am extremely pleased about. The book is titled VMware vCloud Architecture Toolkit (vCAT): Technical and Operational Guidance for Cloud Success. This has been quite a long journey for a lot of us, and we have spent many a long hour writing or editing for this book, and the paper version available on vmware.com. The vCAT book synopsis: The complete vCAT printed reference: knowledge, tools, and validated designs for building high-value vCloud® solutions The vCloud Architecture Toolkit (vCAT) brings together validated designs, tools, and knowledge for architecting, implementing, operating, and consuming modern vCloud infrastructure based on the Software Defined Data Center (SDDC). vCAT has already helped hundreds of VMware customers succeed with vCloud. Now, pioneering VMware architect John Arrasjid has integrated essential vCAT information into a definitive printed […]
BMW E46 M3 vs C32 AMG Mercedes
BMW E46 M3 vs C32 AMG Mercedes, Lets start this by pointing out this is not a virtualization post. Its about my other favourite and passionate topic, CARS. I have been wondering about which is best, and which one would I buy, an E46 M3 or a C32 AMG. This post is mainly for me to understand the differences between the two cars, and hopefully get some responses from owner of both, or either. Lets start off this thought process, I have owned three BMW’s and one Mercedes in my lifetime so far. All of the BMW’s I have loved, (330 CI Clubsport, 325D M Sport Tourer, X3 SE), but my experience with the Mercedes was not good (a C220CDI Avantgarde). I think the experience of the Merc was more about me than the car. Nothing went wrong, but I went from a BMW 330CI Clubsport with 240+BHP to an […]
