Shared storage

FlashGrid Storage Fabric software turns locally attached disks into shared disks accessible from both nodes of the cluster. The sharing is done at the block level with concurrent access from all nodes.

Each database node has a full copy of user data stored on locally attached Premium SSD disks. FlashGrid Read‑Local™ Technology allows serving all read I/O from the locally attached disks and increases both read and write I/O performance. Read requests avoid the extra network hop, thus reducing the latency and the amount of the network traffic. As a result, more network bandwidth is available for the write I/O traffic.

Advanced networking

FlashGrid Cloud Area Network™ (CLAN) enables running high-speed clustered applications in public clouds or multi-datacenter environments with the efficiency and control of a Local Area Network.

Network capabilities enabled by FlashGrid CLAN on Azure:
Each type of traffic has its own virtual LAN with a separate virtual NIC, e.g. fg-pub, fg-priv, fg-storage
Negligible performance overhead compared to the raw network
Minimum guaranteed bandwidth allocation for each traffic type while accommodating traffic bursts
Multicast support
Transparent connectivity across Availability Zones
