I set up a new server 2012 R2 and the server is very slow. CPU and RAM usage is low but the Resource Monitor shows that Disk is 100% for "Highest Active Time" on the 10MB/S scale, while Disk I/O is relatively low. I suspect this is why the ten Pastel clients are timing out continuously. Even with just one or two clients logged in and maybe just running an average sized report, the server seems to be bottle necking with the storage system. When I installed Windows, I installed Intel's latest driver.
I have read various posts and am quite puzzled as what to do about it, there were posts about changing Stripe size of the RAID for to suit SQL and disabling Write Caching on the drives.
Server hardware:
Intel S2400SC-2
3x WD Black SATA 1TB
Using the Intel RSTe embedded software RAID 5
16GB RAM
Software:
Server 2012 R2 64bit
SQL Express 2012
Thanks
