Network Instruments has launched an appliance that allows users to save data to a 2TB, 4TB or 8TB capture buffer or to a storage area network.

The company said that with the GigaStor-WAN probe, data could be gathered and reviewed in real-time without stopping the continuous data capture.

Once data is gathered, it can use the management interface to perform forensic analysis on it, play back voice and video conversations and web transactions, and reconstruct email for corporate governance and compliance.

GigaStor's Write-to-SAN capability lets administrators remove the storage limitation of an 8TB capture buffer.

Network Instruments claims that the GigaStor-WAN captures and decodes all native WAN error and line conditions. It supports capture and write-to-disk rates of over 320MB/s, and can monitor up to 12 links concurrently.
