OCZ Tests SSD Caching Solution for Linux Systems

From Xbit Labs:

OCZ Technology Group has initiated a beta test program for its Linux Acceleration (LXL) software development and invites its enterprise SSD customers to participate. The new OCZ LXL software is a fast caching storage solution for OCZ's portfolio of enterprise SSDs and designed specifically for Linux-based physical and virtual environments.

Details at site.

Recently I purchased an OCZ Vector (512 GB) for my laptop. This drive absolutely screams. Boot time is blindingly fast as well as all operations. I'm now CPU bound.

Cheers,

Such features are also available in a package called bcache (I don't think it's standard in the kernel yet) which acts as a cache to an existing block device, and it's also available in ZFS if you're into that kind of thing.

Bcache is potentially better as the cache contents survive a reboot, but if you like or use ZFS then it's a good choice as well.

I used a OCZ Vertex 4 in my recently built desktop, and I must say I am extremely happy with it. Boot time is incredible. I'm not using it for any caching purposes though.

I have a 3 year old Vertex 2-60GB, and a .8yr old Vertex 3-256GB.

Windows 8 natively supports SSDs, with new defrag.

The V2 has seen so many OSes, and just keeps flying.

Love my SSDs.

The technical details of how this is done is incredibly sparse. All that's given on a technical level is this marketing gobbledegook:

quote:
... 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. ...
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:

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...
