Re: iSeries and SSD drives

[John Jones <chianime@xxxxxxxxx>]

Sometimes its easier and faster to throw hardware at a performance issue
but as a rule, application, database, and OS tuning should occur before
making your reseller happy.  Even if disks are overly busy, it may be a
sign of poor app design or index management more than insufficient disk
performance.
