WAAS cache sync

[andre.ortega]

Hi,

is possible 2 WAE-674 synchronize cache?

Regards.

Andre,

Guys from PDI will probably have a full answer...

But I believe we don't sync caches, the only application of this I could see is during failure or one WAE in cluster. Unless you mean to share DRE cache globally accross all devices?

Hi Marcin,

I am waiting answer for PDI, and I would like to synchronize the cache in cluster to avoid trouble during a failure.

In a cluster has each WAE your cache? Only during a failure the secondary WAE have to learn cache?

Thanks.

Andre,

According to best of my knowledge no DRE/cifs cache syncrhonization is done in case of multiple WAEs.

I believe that this is per design and we've chosed this to have better scalability over uncertain benefit (+ mutliple read/write operations required to sync multiple devices).

Ok, thanks.
