[OpenIndiana-discuss] iops...

[Roy Sigurd Karlsbakk]

Hi all

The numbers I've heard say the number of iops for a raidzn volume should be about the number of iops for the slowest drive in the set. While this might sound like a good base point, I tend to disagree. I've been doing some testing on some raidz2 volumes with various sizes and similar various amount of VDEVs. It seems, with iozone, the number of iops are rather high per drive, up to 250 for these 7k2 drives, even with an 8-drive RAIDz2 VDEV. The testing has not utilized a high number of theads (yet), but still, it looks like for most systems, RAIDzN performance should be quite decent.

Vennlige hilsener / Best regards

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er et elementært imperativ for alle pedagoger å unngå eksessiv anvendelse av idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og relevante synonymer på norsk.
