MSA1500 and MSA20 performance problems

[BR827584]

I have bougth a MSA1500 with 4 MSA20 shelves and 48 250 GB serialATA drives. The performance is very poor, writting to a Raid 5 with 12 disks I can get only 20 MB/seg and the ligths on the MSA1000 controller shows it is using all the CPU. If I connect the same MSA20 with the same disks to a 6400 controller and make the same array I can reach 70-90 MB/seg. If I attach a MSA30 with 14 SCSI disks to the MSA1500 I get more performance (about 60MB/seg. I am using the last firmware (4.82 for the MSA1500 and 1.24 for the MSA20). Is there any problem with my configuration?

Hi,

See the hp supportwebsite in a few days. There should be soon a new firmware mentioned for the MSA1500 4.94 where this should be fixed in.

Probably battery problem...

check your battery values at your MSA20 shelves.

Boot shelve in combination with a serial cable attached to it, value needs to be above 6000mv.

and update to 5.02/1.48 (minimum)
