Not sure if this is the right forum...I have two identical ASA 5520's that were purchased at the same time. I use them in an active/passive failover. This week I noticed that the displayed flash size on the active one was 64 MB and the flash size on the passive one was 256 MB. Is there a reason that the active one would have lowered the flash size if it needed more of the memory for other things? Both have 512 of RAM. I checked the Cisco spec sheet for the 5520 and it lists 64 MB of flash as default. Any suggestions?
