We have an ESSbase server that is running within our Vmware virtual environment. Lately there have been some performance issues, the vendor seems to think that it could be tied to the storage on which the data lives.
From within windows on the guest OS running perfmon during slow performance we noticed that the counter for Disk Transfers/sec was averaging about 40 and sometimes as high as 200. From everything Ive seen online this points to a disk bottleneck.
This server has an RDM attached which is comprised of 4 15k sas drives in a RAID 10 configuration from our EMC VNX SAN so it should be performing better than this.
Im just looking for some advice on what I can monitor through vmware or windows that might provide some insight into the slowness.
Any help is appreciated.
