Hi,
we have a SAP "development" System with MaxDB 7.9 running Windows 2012 on vmware esxi 5.1; vmdk disks for system, swap, DB, LOG and backup file.
SAN is an DELL Equallogic PS6100X (10K SAS). IOMeter performance test seams to be successfull (Windows 2012 - VMware RR 4P - PS6100-bytes.jpg). The drives for DB and backup are on seperate controllers.
During backup the performance is not as good as we expected (ScreenHunter_18 Nov. 06 16.03.jpg). We only get 3.5MB/s per kernel.exe thread.
We have nocomparable system. Is this normal in virtualized SAP systems only to achive a backup rate of 100-120GB per hour?
Or can we also backup on Network Shares or NFS targets? An RDM device instead of vmdk is also possible, but i dont think that the target ist the problem.
Thanks in advance.
Alex
