With the new virtualization technologies such as Virtual SAN vSphere or VMware Virtual Volumes want the software-defined data center push , In addition, the manufacturer is planning to merge together with Google’s cloud platforms vCloud Air and Google Cloud in a single hybrid cloud service. The current status.

With the general availability of vCloud Suite 6 , vSphere with Operations Management 6 and vSphere 6 including Virtual Volumes and VMware Virtual SAN 6 and the strategic importance of VMware’s software-defined storage technology is becoming increasingly clear. Here Virtual SAN 6 and the new Virtual Volumes feature of vSphere 6 play a central role. Both Mark loud VMware a new generation of enterprise storage for a broad range of software-defined storage. VMware Virtual SAN 6 was compared to version 5.5 radically simplified and can provide many enterprise features to support mission-critical applications are available at four times the performance and twice the scalability.

VMware Vitual SAN 6

VMware Virtual SAN is designed as a flawless Software Defined storage product. VMware refers to its SDS-variant as a “hypervisor converged storage solution”. Virtual SAN abstracted and grouped internal DAS (local disks) and Flash Storage ESXi hosts into logical storage pools. These are virtual machines so as shareable data storage. . The result, according to VMware vSphere with 6 Virtual Volumes an unprecedented level of storage integration

The recommended Editors:

VMware Virtual SAN is fully integrated with VMware vSphere and provides functions for policy-based storage management, so that the management model for storage on the device moves to the application. So admins can deploy applications within minutes, with users also benefit from the good integration with the entire VMware stack

.

What’s new in VMware Virtual SAN 6

VMware vSphere Virtual SAN 6 allows, among other things, the construction of a two-stage All-flash architecture in which can be used for both intelligent caching and for the persistent storage of data flash devices. Unlike Virtual SAN 5.5 of the I / O throughput per node due to the new all-flash architecture is more than four times higher and provides predictable latency of concretions less than a millisecond.

allows a VMware Virtual -San cluster with 64 nodes up to seven million input / output operations per second (IOPS), and the whole thing with near linear scaling. Incidentally doubled in Virtual SAN scalability 6 to 64 nodes per cluster. So users can operate up to 6,400 VMs per cluster and extend up to 8 petabytes of storage capacity per cluster.

Further Virtual SAN 6 brings an improved snapshot function that extends the snapshot depth to 32 per virtual machine, while minimizing the performance overhead. In addition, Virtual SAN 6 allows an intelligent placement of virtual objects between server racks. This increases the availability of applications improved even in the case of a full rack failure. In addition, the new support of “direct-attached” -JBODs customers, VMware Virtual SAN 6 clusters in the server blade environments allows for generous scale.

Virtual SAN also provides a flexible, seamless scaling of storage resources. In this capacity and performance can be scaled at the same time, if the cluster, a new host is added (horizontal scale). Capacity and performance can be also independent of each scale by existing hosts to be extended by additional DAS Storage (new disks or SSDs) (vertical scale).
