Yes (with Vendor Add-On: Virtual SAN 6.0)
Details
Virtual SAN 6.0 delivers new all-flash architecture on flash devices to deliver high, predictable performance and sub-millisecond response times for some of the most demanding enterprise applications.
With double the scalability of up to 64 nodes per cluster and up to 200 virtual machines per host along with performance enhancements and highly efficient snapshot and clone technology, Virtual SAN 6.0 is the ideal storage platform for virtual machines.
Hosts per Cluster 64 (vSphere 5.x it was 32)
VMs per Host 200 (vSphere 5.x it was 100)
IOPS per Host 90K (vSphere 5.x it was 20K)
Snapshot depth per VM 32 (vSphere 5.x it was 2)
Virtual Disk size 62 TB (vSphere 5.x it was 2 TB)
Rack Awareness – Virtual SAN 6.0 Fault Domains provide the ability to tolerate rack failures and power failures in addition to disk, network and host failures.
vSphere Requirements
Virtual SAN 6.0 requires VMware vCenter Server 6.0. Both the Microsoft Windows version of vCenter Server and the VMware vCenter Server Appliance can manage Virtual SAN. Virtual SAN 6.0 is configurable and monitored exclusively from only VMware vSphere Web Client.
Virtual SAN requires a minimum of three vSphere hosts contributing local storage capacity in order to form a supported cluster. The minimum, three-host, configuration enables the cluster to meet the lowest availability requirement of tolerating at least one host, disk, or network failure. The vSphere hosts require vSphere version 6.0 or later.
Disk Controlers
Each vSphere host that contributes storage to the Virtual SAN cluster requires a disk controller. This can be a SAS or SATA host bus adapter (HBA) or a RAID controller. However, the RAID controller must function in one of two modes:
- Pass-through mode
- RAID 0 mode
Network Interface Cards (NIC)
In Virtual SAN hybrid architectures each vSphere host must have at least one 1Gb Ethernet or 10Gb Ethernet capable network adapter. VMware recommends 10Gb.
The All-flash architectures are only supported with 10Gb Ethernet capable network adapters. For redundancy and high availability, a team of network adapters can be configured on a per-host basis. The teaming of network adapters for link aggregation (performance) is not supported. VMware considers this to be a best practice but not necessary in building a fully functional Virtual SAN cluster.
