I have a question regarding the bit-level caching which Cisco WAAS performs. In our scenario, we're going to have a central site with a WAE-7326 or WAE-7341, and many (dozens) of remote sites with WAE-512 devices. Data transfer between all the sites will be very similar.
The way I understand it, is that the caching happens between pairs of devices, and the result is that chunks of data may be repeated on the central site unit for each remote site which transferred the same chunk of data.
Similar products can share the same cached data with multiple remote sites, improving scalability at the central site.
Is there any way to mitigate this behaviour? I suspect it is going to greatly reduce our cache hit rate and affect performance.
