Used Cisco Persistent Storage Device (PSD)

Part # WS-SVC-PSD-1

Product Description: This Cisco Persistent Storage Device (PSD) device tracks when information fails and calls detail records (CDRs) and their associated revenues-can be lost. Outages can be planned (system upgrades) or unplanned (network connection failure or data collector failure). A redundant data collector setup is not enough-reliable physical media is necessary to safely store the CDRs generated during an outage.

With the Cisco PSD’s 37-GB on-board storage space, CDRs from up to 3 Cisco CSGs or 3 GGSNs can be safely be stored which provides, in many instances, several day’s worth of protection. A single Cisco PSD can support the Cisco GGSN and CSG concurrently. The number of PSDs required can be determined based on expected network traffic and the corresponding number of billing records the CSGs or GGSNs would generate.
