Our biggest customer installed a new server over the weekend, and is experiencing a great drop in performance compared to the old server.
The server is a HP ProLiant BL460c Gen8. 64 GB RAM. 2 x 200GB SSD drives in RAID 1 setup. Win2012.
The database is about 22 GB in size, and was rebuilt using unload/reload, pagesize 8K.
The IT-manager has been monitoring the IO to the disks on the server, and for regular usage it's averaging around 500 MB/s. But when monitoring the db and log files, the IO is only between 100 KB/s and 1 MB/s. Which is way lower than expected.
Any first thoughts on why this server is not operating as expected when it comes to performance? Perhaps there is some switches we can add to the startup? Or something else we can check up on?
