I/O Performance RS 500 SAS G8

aubergine

Hi,

hat zufällig jemand einen Rootserver RS 500 SAS G8 und kann etwas zur I/O Performance sagen?

Super wäre eine Messung mit z.B. fio auf einem Server auf dem aktuell kaum I/O stattfindet.

Code

fio --ioengine=libaio --direct=1 --name=fio.raw --bs=4k --size=200M --readwrite=randrw
fio --ioengine=libaio --direct=1 --name=fio.raw --bs=4k --size=400M --readwrite=rw

Danke vorab

Ich hab mit fio nie gearbeitet, beim 2. Command möchte er nicht.

Code

fio: failed parsing readwrite=rw

Dank dir vielmals.

Der Schalter ist scheinbar versionsabhängig. Bei dir müsste das --readwrite=readwrite heißen.

Hattest du fio auf der SAS Variante dieses Servertyps ausgeführt?

Ja, RS 500 SAS G8
