HPE Smart Array P408i-a SR Gen10 - RAID6 (ADG)

Guten Tag

Server: ProLiant ML350 Gen10
Product ID: 877623-421
Storage Controller: HPE Smart Array P408i-a SR Gen10

Disk: SAS 600GB
Model: EH000600JWHPN
Geschwindigkeit: 15k
Anzahl: 8
Fehlertoleranz: RAID 6 (ADG)

Ich verwende einen HP ProLiant ML350 Gen10 mit einem Smart Array Controller P408i-a Storage Controller. Ich habe 8 Stk. Disk in einem RAID (ADG) Verbund.

Ich habe schon mehrmals von Berufskollegen mitbekommen, dass ein RAID 6(ADG) nicht optimal mit 8 Disk arbeitet. Ideal wären fünf Disk oder neun Disk. Der Controller könne so optimaler arbeiten.
Hat jemand schon Erfahrungen damit gemacht oder weiss jemand etwas davon ?

Ich freue mich auf einen Antwort und danke euch für eurte mühungen.

Gruss

Chris

Good day

Server: ProLiant ML350 Gen10
Product ID: 877623-421
Storage Controller: HPE Smart Array P408i-a SR Gen10

Disk: SAS 600GB
Model: EH000600JWHPN
Speed: 15k
Number: 8
Fault Tolerance: RAID 6 (ADG)

I'm using an HP ProLiant ML350 Gen10 with a Smart Array Controller P408i-a storage controller. I have 8 pcs of disk in a RAID (ADG) composite.

I've heard from colleagues a number of times that a RAID 6 (ADG) does not work optimally with 8 disk. Ideal would be five disk or nine disk. The controller could thus work optimally.
Has anyone had any experience with it or does anyone know about it?

I look forward to an answer and thank you for your efforts.

Greeting
Chris

Hello, 

In Raid 6, increasing the number of drives will increase the Read speed. But the write speed will not have much difference.

So for example, if we have 8 drives with 1TB each in RAID 6

Usable Capacity 6 TB

Speed 6x read speed, no write speed gain

 

And if we use 6 Drives with 1TB each in RAID 6 

Usable Capacity 4 TB

Speed  4x read speed, no write speed gain

 

I hope the above example explained above answers your question.

Regards

Raj
