VMware on Thursday announced the release its Virtual SAN product that has been in beta test since August 2013.
Virtual SAN, or VSAN for short, is part of VMware’s Virtual Volumes Initiative, which aims to make storage VM-centric.
VSAN is integrated into vSphere and aggregates server disks in a cluster to create shared storage that can be provisioned from vCenter during creation of a virtual machine. It is object-based and fully compatible with VMware vSphere High Availability, vSphere Distributed Resource Scheduler and vSphere vMotion.
Each vSphere host participating in the VSAN cluster requires a SAS or SATA HBA or RAID controller, its own local HDD and one SSD. The HDDs make up the storage capacity of the VSAN datastore; the SSDs provide a write buffer and read cache for faster performance and faster rebuild in the event of a failure. VSAN scales to as many as 32 attached nodes. The vSphere host must also contain a 1GbE or 10GbE network adapter.
Partners of VMware for VSAN include Cisco, Dell, Fujitsu, Hitachi, HP, IBM and Lenovo on the server side. In storage, EMC, Fusion-io, Intel, LSI, Micron, NEC, Samsung, SanDisk and Virident are partners. In the data protection area – at present the most common use case for VSAN, Acronis, Actifio, Commvault, Symantec and Veeam are partners.
The product is expected to be available on a standalone basis and requires a vSphere license.
