Supermicro, VSAN and EVO:Rail

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...

Micron demos all-flash VSAN

For their VMworld demo, Micron is taking VSAN to a whole new level by creating an all flash VSAN. The thought process behind this is to demonstrate “best in class” performance of a VSAN configuration. Eliminating the storage bottlenecks on the data store by using 100% solid state storage and the latest high speed network interconnects, Micron is aiming for performance that can push the limits of storage. Micron’s all flash VSAN configuration includes a 6 node cluster of Dell R610, Dual 2.7Ghz 12 core Xeon v2 CPU, 10 x 960GB Micron M500 SSD for the data storage, 2 x 1.4TB HHHL Micron P420m PCIe SSDs for the VSAN cache, and 768GB RAM, configured into 2 disk groups. Each disk group consists of 1x P420 and 5 x M500 drives. The M500 SSD drives are rated up to 80,000/80,000 random read/write IOPS each. The PCIe P420m is rated at read 750,000 IOPS with write IOPS at 95,000. With these kind of statistics, expect to see some great throughput. The end result is 9.4TB of storage space and 1.9TB of read cache, which results into a 1:5 cache to data ratio. (The unrepresented cache space is used for the write buffer which is 840GB for each host.) The VMworld demo has Active Directory and VMs running various applications – including high-IOPS-consuming Microsoft SQL server and backups using Veeam. The VDI deployment on the VSAN showcases what kind of performance can be achieved when storage bottlenecks are removed. The all flash VSAN is not a fully supported configuration at the moment; however, when VMware does support it Micron will be ready. If you are at VMworld San Fransisco, stop by the Micron booth to see the demo and what kind of high performance VSAN you can...
