Database High Availability Simplified

Flash Storage for Virtualized Oracle RAC

Running Oracle RAC on virtualized nodes allows reducing the amount of hardware while ensuring full isolation of resources between separate databases.

FlashGrid Storage Fabric software enables high-performance storage shared between VMs. Each VM has its own set of dedicated local NVMe SSDs installed in the hypervisor server. Each NVMe SSD provides performance comparable to an all-flash array. FlashGrid Read-Local™ Technology minimizes the storage network I/O between nodes by serving all read requests from local SSDs. Optional use of PCI Pass-Through for the NVMe SSDs and for NICs allows achieving performance of bare-metal while keeping the flexibility of using virtual machines.

Data mirroring and volume management is done by the proven Oracle ASM running inside the VMs, thus eliminating the risk associated with 3rd-party data management.

The solution can be deployed on Oracle VM, VMware, or KVM.

“We had to migrate dozens of mission critical Oracle RAC databases from Exadata to AWS with FlashGrid SkyCluster, and were able to do it without sacrificing performance or availability.”

Rama Kolli, Sr. Director – Database Management, S&P Global Ratings

“FlashGrid SkyCluster provides us all elements needed for running our mission-critical Oracle databases in Azure: storage and networking software, deployment automation, and 24x7 support.”

Jay Wilder, Sr. Director of Software Engineering, Nuance Communications

“With FlashGrid and AWS we can now deploy a new application within two weeks instead of six months, without compromising our availability SLA.”

David Urban, VP Operations, Aria Systems

“SkyCluster for Azure proved to be a reliable solution that is easy to implement and support for us as a systems integrator.”


“With our new virtualized RAC running on FlashGrid architecture we do a 125GB full table scan in 6 seconds. That is an 11x improvement over our previous setup.”

Sam Shiel, Oracle DBA, Simplyhealth

“Implementing Oracle RAC with FlashGrid in AWS is an important milestone in Digital Virgo’s cloud journey.”

Mikolaj Klimek, Deputy Director IT Operations and Infrastructure, Digital Virgo
