Users can now migrate block-level data from anywhere into any of Azure’s block storage offerings using the Cirrus Migrate Cloud Block storage. It delivers high performance and provides granular access to raw data, making it highly suitable for Tier-1 business critical applications. The versatility of block storage also allows it to be used as boot disks (OS disks) and data disks supporting virtual machine-based file systems, RAID arrays, databases, and container applications. On-premises, scalable block storage is mainly provided by SAN (Storage Area Network) appliances, and Cirrus Data helps migrate those to Azure - for example, to Azure Elastic SAN (in preview).
