How much L2 cache is read vs write?

[rrbnc]

Is there a set percent of the L2 cache that is dedicated to read cache vs write buffer in StarWind? For instance I think VMware vSAN's cache drives are dedicated 70% to read cache and 30% to write buffer.

L2 cache is used for hosting read operations. It operates on write-through mode and this cannot boost writes.

Thanks. Does L1 cache contribute to write buffering? If so how much of L1 cache is write buffer vs read cache?

[Boris (staff)]

L1 cache is completely dedicated to boosting write operations. While the data is still cached, it can be read from L1 cache directly with no need to address the storage.
