NetApp Terminology - Disks


NetApp currently uses 3 types of disks:

FCP (Fiber) – fast, expensive, on all models, originally in filers
SATA (Serial ATA) – slower, cheaper, on all models, originally on nearstores
SAS (Serial Attached SCSI) – fast, expensive, currently only on FAS20x0 series, poised to replace FCP in the long run

-Now:

Recent models can combine FC, SATA, & SAS disks
SATA is slower than FCP & SAS
Note: “FCAL = Fiber Channel – Arbitrated Loop”
A fast, serial-based standard meant to replace the parallel SCSI standard
Primarily used to connect storage devices to servers
