Device-Independent Storage Virtualization Software, 
Core to Your IT Infrastructure 

Over the past decade DataCore has developed sophisticated storage virtualization technologies to overcome device-specific differences and limitations so that you may experience non-stop, lightning-fast, waste-free SANs despite continuous changes in the makeup of your storage pool. We use software to transform imperfect storage hardware devices into ideally behaved disks; i.e., “virtual disks” that have plenty of capacity, run fast, are easily shared, never age and are always accessible. This unique emulation overcomes differences, limitations and flaws inherent in all real devices, whether they are basic disk drives or top-of-the-line disk arrays.

The software harnesses the power of dedicated x86/x64 Windows servers to speed up disk response, execute replication, data protection, and other advanced functions, while generally managing the allocation of the virtual storage pool. The servers effectively turn into locked down, “storage virtualization nodes” and cease to be general purpose machines. They may be chosen from your preferred manufacturer and sized to your specific I/O requirements.

Configuring the DataCore nodes for N+1 redundancy eliminates single points of failure. This allows one node and its resources to be taken out-of-service for repairs, upgrades, expansion and replacement while another takes over its duties without disruption.

Unlike device-specific  firmware, there’s no discarded investment and no upheaval in your storage practice when you transition to the next hardware platform. It’s as portable as moving your database server and its licenses to a faster machine. You can run DataCore software on physical and virtual machines for the widest choice of platforms and compatibility. Up to 1 TB of SAN-wide cache per DataCore node can be configured for unprecedented, lightning-fast response from modest back-end disks.

The software pools free space from any disks internal to the nodes and any direct-attached or SAN-based external arrays. The system administrator carves out virtual disks from this resource pool according to the specific capacity, availability and performance needs of your computers. For example, some groups of virtual disks may be defined to be cached, locally mirrored, remotely replicated and thinly provisioned. In the background, the DataCore software will tap multiple real devices and the necessary computing and network connections to meet those requirements. The virtual disks are then assigned to specific iSCSI or Fibre Channel ports on the computers needing storage where they appear as conventional disks on a SAN.

DataCore supports storage consumers running any of the popular operating systems. It is compatible with Windows, MacOS, Linux, HP-UX, AIX, and Solaris, but does not depend on host-based agents to provide services. Server and desktop virtualization products from companies like Citrix, Microsoft and VMware depend on DataCore SANs for well behaved, highly-available, shared storage. They realize distinct availability and performance advantages when implementing virtual machine migrations, workload fail-over and dynamic load balancing.
