Short stroking disk drives to improve performance

Print Friendly, PDF & Email

Reading a post from┬áHans DeLeenheer (VEEAM) which ramped up quite a bit including responses from Calvin Zito (HP), Alex McDonald (NetApp) and┬áNigel Poulton. The discussion started on a comment that XIO had “special” firmware which improved IO performance. Immediately the term “short-stroking” came up which leads to believe X-IO is cheap-skating on their technologies. I was under the same impression at first right until the moment I saw that Richard Lary is (more or less) the head of tech at X-IO together with Clark Lubbers and Bill Pagano who also come out of the same DEC stable. For those of you who don’t know Richie, he’s the one who ramped up Digital StorageWorks back in the late 70’s/early 80’s and also stood at the cradle of VAX-VMS. (Yeah yeah, I’m getting old, google it if you don’t know what I’m talking about.)
