Running business critical stuff on b134 isn''t what I''d
recommend - no updates anymore - either use S10, or S11ex or perhaps
openindiana.

Most drives should work well for a pure SSD pool. I have a postgresql database
on a linux box on a mirrored set of C300s. AFAIK ZFS doesn''t yet
support TRIM, so that can be an issue. Apart from that, it should work well.

Vennlige hilsener / Best regards

I all pedagogikk er det essensielt at pensum presenteres intelligibelt. Det er
et element?rt imperativ for alle pedagoger ? unng? eksessiv anvendelse av
idiomer med fremmed opprinnelse. I de fleste tilfeller eksisterer adekvate og
relevante synonymer p? norsk.
