VMware's Latest Release VSAN 6.1 to Provide Greater Availability and Management Abilities
VSAN 6.1 focuses on delivering high performance and increased scale and aims at providing enterprise-class storage for virtualized workloads, it will include Tier-1 production and business-critical applications. Since its release, the previous version VSAN 6.0 has successfully run mission critical application for its customers and with the release of the latest version VSAN 6.1, VMware looks at expanding VSAN’s capabilities in areas of enterprise availability and data protection, reports Adam Armstrong for StorageReview.com.
The latest release VSAN 6.1 comes with features listed below:
Virtual SAN Stretched Cluster: VSAN 6.1 is able to have a stretched cluster across multiple geographically separated sites with the ability to synchronously replicate the data between sites.
Virtual SAN for Remote Office / Branch Office (ROBO): It provides the ability and support for deploying VSAN clusters for ROBO locations.
Virtual SAN Replication with vSphere Replication: By utilizing vSphere Replication for its replication data services, vSphere Replication and VSAN support RPOs and VMware’s Site Recovery manager )SRM) can be used to deliver a completely orchestrated disaster recovery solution.
Support for Multi-Processor Fault Tolerance (SMP-FT): VSAN 6.1 supports vSphere Fault Tolerance feature and provide continuous availability with zero downtime for mission critical applications in the event of hardware failure.
Support for Windows Server Failover Clustering (WSFC) and Oracle Real Application Cluster (RAC): VSAN 6.1 supports clustering technologies from both Oracle and Microsoft, furthermore it will also now support Windows Server Failover Clustering (WSFC) failover clustering functionality is enabled, and can guard against application and service failures.
Maximum Performance and Low latencies: VMware will continue performance improvements of VSAN by expanding their support of the new type of hardware devices and interfaces.
ULLtra DIMM: ULLtra DIMM SSDs connect flash storage to the memory channel via DIMM slots, achieving very low (<5us) write latency. Ultra DIMM provides even greater density and performance – for example, it allows for a 12-TB All Flash Virtual SAN host in a thin blade form factor, as well as 3x improvement in latency compared to external arrays.
Non-Volatile Memory Express (NVMe): NVMe is a new communications interface which has been developed especially for SSDs, this will allow for greater parallelism for both hardware and software to be utilized resulting in various performance improvements. Leveraging NVMe in a VSAN as an all flash deployment resulted in 3.2M IOPS measured on a 32-node cluster – ~100K IOPS/Host.
Virtual SAN Health Check-Plug-in: This feature is a vCenter Server plug-in for the vSphere Web Client designed to provide and centralize health reporting solution that checks all aspects of the Virtual SAN configuration and health of hardware, data and its limits.
Virtual SAN Management Pack for vRealize Operations: integration of VSAN 6.1 with vRealize operations delivers a comprehensive set of features to help manage Virtual SAN with global data visualization.
