Supermicro and VMware have released a new generation of VMware EVO:RAIL appliances and VMware Virtual SAN Ready Nodes.  The arrival of the new Supermicro servers is occurring alongside the release of VMware’s vSphere 6.0 suite, which is VMware’s most important release in several years.  Combined, the Supermicro and VMware launches are more than simply an incremental improvement and serve as an exceptional showcase for the power and flexibility the modern software defined datacenter is capable of delivering. The 2015 generation of Supermicro servers that have been specially designed with VMware’s VSAN and EVO:RAIL in mind are the 2U TwinPro² and the 4U FatTwin series servers.  Supermicro’s various partners have led the industry in delivering hyperconverged solutions using previous generations of Twin series servers.  Lessons learned there, combined with the increased capability of the next generation of VMware software, have driven the design of the next generation Supermicro Twin series servers. Increments of change A generational change can occur either because a major feature is introduced, or through a series of iterative implements that, combined, result in a significantly superior product.  The 2015 Twin series servers have done both. Supermicro hasn’t simply relied on evolving standards and new generations of equipment being made available by upstream partners.  The quality of Supermicro servers (which Supermicro feels was already quite good) has been significantly improved.  Supermicro is constantly working with customers and partners to identify design elements that need improvement, and the 2015 servers are the result of many such changes. The most notable incremental improvement will be found in the addition of Supermicro’s Titanium Level high-efficiency digital power supplies (more detail below) and architecture designs that improve airflow for optimal cooling. In addition to these green computing improvements, the rail kits have undergone several design tweaks...
