Re: OCZ Tests SSD Caching Solution for Linux Systems
The technical details of how this is done is incredibly sparse. All that's given on a technical level is this marketing gobbledegook:
quote:To me, that reads as: there are two Linux kernel modules you need to load to accomplish this task. And I have two comments on this:
... It achieves this type of dynamic cache selection optimization by splitting the caching policy engine between the core mechanism running in the Linux kernel and an advanced statistical out-of-band analysis module that optimally determines which data needs to be placed in the cache and stores the data locally in OCZ enterprise-SSDs. ...
1. Are these modules open-source or binary blobs? If binary blobs, then this will almost certainly fail,
2. Why is this being implemented like this? Either the underlying a) filesystem, or b) block/device I/O, layer should be responsible for this kind of thing. Honestly if I had to pick (a) or (b), it would be (a).
Sometimes I don't understand what OCZ is doing...
