sda contains /, /tmp, /usr, /var and swap. sdb, sdc and sdd contain only 1 partition each: sdb1, sdc1 and sdd1. md0 is made of sdb1, sdc1 and sdd1

I found the problem.
The reason why sda is under heavy stress when using dd on md0(sdb,sdc,sdd) is the swap.
Using 10 times dd with bs=1G require 10G memory which I don't have. So the system uses the swap on sda and md0 is quietly waiting doing nothing.
Using 10 times dd with bs=256M require 2.5G memory which I have. So all the stress is on md0.

I have read anecdotes about people installing RAID0 (RAID - Wikipedia, the free encyclopedia) on some of their machines because it gives a performance boost. Because bandwidth on the motherboard is limited, can someone explain exactly why it should be faster? (7 Replies)

Both servers share an external SCSI disk array. Both server runs a Data base wich uses the disk array to write the data, and that is the way they share the information.

Hello,
On 4/20/2018, we performed a disk replacement on our IBM 8202 P7 server. After the disk was rebuilt, the SAS Disk Array sissas0 showed a status of degraded. However, the pdisks in the array all show a status of active.
We did see a message in errpt. DISK ARRAY PROTECTION SUSPENDED.
