Hello,
We're having a problem with a new server we've recently set up. It's a Windows Server 2012 R2 virtual machine running under ESXi 5.1. It has 16GB RAM, 2 allocated CPU cores, 2 VHDs (120GB C, 100GB D:) linked to our one and only datastore which is direct attached storage on the host (4x NL-SAS 4TB HDDs running in RAID10 in a Dell PowerEdge R515 if that matters).
It runs Microsoft SQL Server 2014 Standard and has been set up to act as an on-site data warehouse as a central repository for various disparate data stores spread locally and on the web so that we can perform in-depth reporting and analysis.
To transform the data, we have a number of scheduled ETL processes to perform various tasks.
We have found that when updating tables the lookup transformation is causing very high disk latency. By default it was set to Full Cache Mode...
