IO Spikes

Hello:

I'm not a server guy per say and not overly technical but I'm getting IO spikes. Some aren't to bad and some are worse then others. My notification goes off if it goes over 1000 IO ops/sec.

My server has 1.5 GIG of RAM, 60GB of space and my swap is at the default of 512MB.

The techs here at Linode directed me to the knowledge base about changing the mySQL settings and the apache settings which I've done a while back.

I have no idea what else I can try if anything to cure these spikes that go over the 1000 point.

If anyone out there can help it would be very much appreciated.
