Hmmmm, I have an F540 filer. I'm sure it's a 540. Positive. Says 540 on it somewhere. I'm sure.

No such thing as a 540 on www.netapp.com. There's a 520, which looks pretty darn similar. Can I just s/540/520/g, and be a happy camper? -- End of excerpt from Jaye Mathisen

Not quite. But almost. We've got an F540 and an F520 here, the differences are slight but significant.

The F520 uses FW/SE while the F540 shipped with FW/D SCSI interfaces.

A few bits of the F520's are more recent than the F540 - NVRAM cards for example.

Plus the F540 was rated as a FOADBMF (a big machine) at launch and NetApp revised down what customers could expect from it, and relaunched it as the F520 in the shadow of the F630 which was the new FOADBMF in town until the F760 came on the scene. 8)
