ASA 5520 Flash Size

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?

Thanks,

Jeff

Re: ASA 5520 Flash Size

Flash is never used instead of RAM, so you really have one unit with 64 and one with 256 (unless you put in a compact flash card of your own and were looking at that instead of the builtin flash).

I guess you just were lucky to get a free upgrade.

Show version will show you what size of flash is installed.
