Testing with and without the LSIprovider installed. This is only for my two SSDs attached the the Dell PERC H310 controller in a RAID1 setup. The test was done in a default Ubuntu Try session and a 17GB VM drive. All tests were repeated several time and ESXi was reinstalled several times because I couldn't believe the results. To summarize, installing the LSIprovider file slows the system down considerably. So I can live with this for now. I will need to find another way to check the drive status, maybe once a month I will need to jump into the PERC H310 card to check the status manually.
