:RAID 0. I know, I know, it sounds almost suicidal but as I
:said speed is more
:important in this instance than recovery. We'll be testing
:this 760 against
:an Auspex, which can be configured to use RAID 0, so I was
:wondering if the
:NetApps could also do this.
---Actually, the way RAID4 is used in conjunction with WAFL, really looks and feels like RAID0, just with a parity write at the end. WAFL removes the problem on a UFS type filesystem of having that single parity drive just thrash to tiny bits, taking the stripe performance with it. When a series of writes comes into the box, it is buffered *im making this simple*, and it flushed out to disk (on a 760) ever 10 seconds, of when 16Mb of data is in the buffer (NVRAM). A single stripe (or series of stripes) is then written in a _very_ optimized manner using the WAFL filesystem, and a single parity calculation/write is created per stripe. I direct you to a document Mr. Hitz wrote at http://www.netapp.com/tech_library/3001.html for more details. I have every confidence you will enjoy our performance in your testing.
