WhipTail Tech announced on Wednesday that its Datacenter XLR8r solid-state storage appliance now supports synchronous and asynchronous high-availability. With two appliances connected via dual 10Gb Ethernet, a heartbeat function synchronizes the devices. Data can be written to either appliance at any time. Asynchronous HA allows the replication of two geographically disperse devices. The HA solution is expected to be available in September starting at $15,000.
