Hi Team ,
We have 2 app and 2 db servers of 11iv3 each 16c / 256 GB RAM , rx2800 i4 .
We are facing tremendus performance issue for our batch jobs commencing from 9pm everyday.
We collected sar statistics , and it shows %wio is consistently above 40 for 4 hrs.
These all 4 servers each has 2 hba connected to EMC SAn switch 8gb , and storage is VNX 5500 with
24GB Cache
12 nos. of 8Gbps FC port
6Gbps SAS back-end architecture.
85 nos. of 300GB 15K SAS drives
58 nos. of 600GB 15K SAS drives
8 nos. of 2TB NL SAS drives
5 nos. of 100GB SSD
Application is finance related & database is oracle 11g.
Tried all parametrs filecache,hires,etc...no use
DB async_io false , increased SGA ...no use
Now if we increase number of HBA's will our perfmnce improve ?
We already have EMC multipathing software
PFA sar o/p colected during performance degradation
Solved! Go to Solution.
