For Service Providers who are looking to lower the costs of launching new services like VMware vCloud Availability, exploring the use cases with VMware vSAN is essential. This vTechTalk gives an overview of how VMware vSAN can help a Service Provider drive down costs and build new services quickly. For further information go to cloudproviders.vmware.com
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 […]
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 […]
