Database High Availability Simplified

FlashGrid Cloud Area Network

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.

A typical network configuration in a public cloud or between data centers provides only a single communication channel between VMs or servers. Even configuring additional NICs may not be enough because the channel bandwidth is shared between the NICs. This constraint makes high-performance clustering challenging because lower priority traffic can occupy all available bandwidth and starve other types of traffic. Other advanced network features, such as multicast or virtual IPs, required by clustering software are often not available.

FlashGrid CLAN removes these limitations by creating a set of high-speed virtual LAN networks and ensuring QoS between them. With FlashGrid CLAN the most advanced clustered applications can be deployed in public cloud or across data centers.

Network capabilities enabled by FlashGrid CLAN

  • Each type of traffic has its own virtual LAN with a separate virtual NIC, e.g. fg-pub, fg-priv, fg-storage
  • Minimum guaranteed bandwidth allocation for each traffic type while accommodating traffic bursts
  • Low latency of high priority traffic in the presence of large volumes of lower priority traffic
  • Transparent connectivity across availability zones or data centers
  • Virtual IP addresses
  • Multicast
