DataCore: The big barrier to virtualization is storage, so it should be no surprise that VMware is trying to do more in this area; however, it is not their primary area of expertise. Thin provisioning is a good thing and is the centerpiece of the vStorage announcement. However, DataCore was doing thin provisioning 10 years ago, and we have continued to evolve and enhance the capabilities, but it is just one component of doing a comprehensive storage virtualization capability. Most shops have a combination of systems that are not virtualized and VMware does nothing for those. In truth, the world contains a mix of physical and virtual systems and storage virtualization that only works for VMs misses the reality of today's environments. Also, virtualization of many servers and the consolidation that comes from it stresses many performance and high-availability aspects of storage. DataCore has been designed to work with both the physical and virtual worlds, provides high-performance caching software (the new releases support Mega Caches) to overcome performance bottlenecks and provides the high-availability (automatic failover and failback) required to enable non-stop storage for business continuity. Whether the applications reside on VMs or on other platforms, DataCore safeguards the storage, makes it faster and more efficient.
DataCore also realizes that the world is not only a mix of physical and virtual worlds but that hypervisors are becoming a commodity, and therefore, the ability to work and support all the major hypervisors and migrate and manage storage for all the brands is essential.
InfoWorld: So tell us, why are DataCore-powered SANs necessary for VMware environments?
DataCore: Virtually everything hinges on storage. Server and desktop consolidation, in particular, place extraordinary demands on it. Too often, disks slow down, interrupt, or endanger these centralized IT operations, not because they are poorly built, but because they are physically constrained. Although VMware virtualization helps you to overcome similar limitations in processors, when it comes to advanced functions such as workload migration, load balancing, fail-over, and disaster recovery, it is completely dependent on highly available (HA), shared storage. You'll be shocked at the high hardware costs and major overhaul generally proposed to put such a storage infrastructure in place.
InfoWorld: Would you go so far as to say that DataCore storage virtualization solutions are essential for VMware environments? And if so, why?
