2.2 FCD Duplication: Binary and File System

FCD operates in two main modes: Binary or File System (aka Smart Duplication).

Either mode is selected based on settings in the FCD Manager.

2.3 Binary Mode Operation

information sector-by-sector. In binary mode, duplicator can use duplicated data from the following sources:

• Master Flash Card/Drive

• Binary image le with multicast streaming

2.3.1. Using a Master Card as a source of duplicated data

When Master Card or Drive is being used as the source of duplicated data in a binary mode, Master card

must be present in Master Slot before duplication can be started. Slave cards are not required to be the same

size as master card for duplication process to start, but user must understand the results of duplication of

mismatching cards in binary mode.

Ifmastercardislargerthanaslavecards,someofthedatawillnott;asaresultslavecardswillnotbean

exact copy of Master Card. The same logic applies to the case when slave card is larger than a master. We

leave it for the user to decide if use of mismatching cards is appropriate in each individual case.

Ifapplicationrequiresthatmasterandslavecardsmustmatch,FCDManagerofferscongurationparameter

«Master-Slave Size Match Control», enabling which prevents duplication from starting if size of Slave Cards

is not identical to the size of Master Card. By default this parameter is turned off.

2.3.2. Using Card/Drive Binary Image File as a source of duplicated data

has to be present in master Card slot. The same consideration about mismatching card sizes applies here.

2.3.3. Using Multicast Streaming (In Development)

To support higher quantities of simultaneously duplicated cards, FCD supports stacked multicast operation.

In this mode up to 100 duplicators can copy data transmitted by FCD Manager application via IP multicast.

All FCD units in multicast stack must be connected to Fast Ethernet switch. Due to the nature of multicast

transmission, concurrent operation of multiple duplicators will take the same amount of bandwidth and time
